999 Westine Apr 87 Requests For Comments Summary
This memo.
998 Lambert Mar 87 NETBLT: A Bulk Data Transfer
Protocol
This document is a description of, and a specification for, the NETBLT
protocol. It is a revision of the specification published in RFC-969.
NETBLT (NETwork BLock Transfer) is a transport level protocol intended
for the rapid transfer of a large quantity of data between computers.
It provides a transfer that is reliable and flow controlled, and is
designed to provide maximum throughput over a wide variety of networks.
Although NETBLT currently runs on top of the Internet Protocol (IP), it
should be able to operate on top of any datagram protocol similar in
function to IP. This document is published for discussion and comment,
and does not constitute a standard. The proposal may change and certain
parts of the protocol have not yet been specified; implementation of this
document is therefore not advised. Obsoletes RFC-969.
997 Reynolds Mar 87 Internet Numbers
This memo is an official status report on the network numbers used in
the Internet community. As of 1-Mar-87 the Network Information Center
(NIC) at SRI International has assumed responsibility for assignment of
Network Numbers and Autonomous System Numbers. This RFC documents the
current assignments of these numbers at the time of this transfer of
responsibility. Obsoletes RFC-990, 960, 943, 923 and 900.
Westine & Postel [Page 1]
RFC 999 March 1987
996 Mills Feb 87 Statistics Server
This RFC specifies a standard for the ARPA Internet community. Hosts and
gateways on the DARPA Internet that choose to implement a remote
statistics monitoring facility may use this protocol to send statistics
data upon request to a monitoring center or debugging host.
995 ANSI Apr 86 End System to Intermediate System
Routing Exchange Protocol for use in
conjunction with ISO 8473.
This Protocol is one of a set of International Standards produced to
facilitate the interconnection of open systems. The set of standards
covers the services and protocols required to achieve such interconnection.
This Protocol is positioned with respect to other related standards by
the layers defined in the Reference Model for Open Systems Interconnection
(ISO 7498) and by the structure defined in the Internal Organization of the
Network Layer (DIS 8648). In particular, it is a protocol of the Network
Layer. This Protocol permits End Systems and Intermediate Systems to
exchange configuration and routing information to facilitate the operation
of the routing and relaying functions of the Network Layer.
994 ANSI Mar 86 Final Text of DIS 8473, Protocol for
Providing the Connectionless Mode
Network Service
This Protocol Standard is one of a set of International Standards
produced to facilitate the interconnection of open systems. The set of
standards covers the services and protocols required to achieve such
interconnection. This Protocol Standard is positioned with respect to
other related standards by the layers defined in the Reference Model
for Open Systems Interconnection (ISO 7498). In particular, it is a
protocol of the Network Layer. This Protocol may be used between
network-entities in end systems or in Network Layer relay systems (or
both). It provides the Connectionless-mode Network Service as defined
in Addendum 1 to the Network Service Definition Covering Connectionless-mode
Transmission (ISO 8348/AD1).
993 Clark Dec 86 PCMAIL: A Distributed Mail System for
Personal Computers
This document is a discussion of the Pcmail workstation-based
distributed mail system. It is a revision of the design published in
NIC RFC-984. The revision is based on discussion and comment fromm a
variety of sources, as well as further research into the design of
interactive Pcmail clients and the use of client code on machines other
than IBM PCs. As this design may change, implementation of this
document is not advised. Obsoletes RFC-984.

RFC 999 March 1987
992 Birman Nov 86 On Communication Support for
Fault-Tolerant Process Groups
This memo describes a collection of multicast communication primitives
integrated with a mechanism for handling process failure and recovery.
These primitives facilitate the implementation of fault-tolerant process
groups, which can be used to provide distributed services in an
environment subject to non-malicious crash failures.
991 Reynolds Nov 86 Official ARPA-Internet Protocols
This RFC identifies the documents specifying the official protocols used
in the Internet. Comments indicate any revisions or changes planned.
This memo is an official status report on the numbers used in protocols
in the ARPA-Internet community. Obsoletes RFC-961, 944 and 924.
990 Reynolds Nov 86 Assigned Numbers
This Network Working Group Request for Comments documents the currently
assigned values from several series of numbers used in network protocol
implementations. This memo is an official status report on the numbers
used in protocols in the ARPA-Internet community. See RFC-997. Obsoletes
RFC-960, 943, 923 and 900.
989 Linn Feb 87 Privacy Enhancement for Internet
Electronic Mail: Part I: Message
Encipherment and Authentication
Procedures
This RFC suggests a proposed protocol for the Internet community and
requests discussion and suggestions for improvements. This RFC is the
outgrowth of a series of IAB Privacy Task Force meetings and of internal
working papers distributed for those meetings. This RFC defines message
encipherment and authentication procedures, as the initial phase of an
effort to provide privacy enhancement services for electronic mail
transfer in the Internet. It is intended that the procedures defined
here be compatible with a wide range of key management approaches,
including both conventional (symmetric) and public-key (asymmetric)
approaches for encryption of data encrypting keys. Use of conventional
cryptography for message text encryption and/or authentication is
anticipated.
988 Deering Jul 86 Host Extensions for IP Multicasting
This memo specifies the extensions required of a host implementation of
the Internet Protocol (IP) to support internetwork multicasting. This
specification supersedes that given in RFC-966, and constitutes a
proposed protocol standard for IP multicasting in the ARPA-Internet.
The reader is directed to RFC-966 for a discussion of the motivation and
rationale behind the multicasting extension specified here.
Westine & Postel [Page 3]
RFC 999 March 1987
987 Kille Jun 86 Mapping between X.400 and RFC-822
The X.400 series protocols have been defined by CCITT to provide an
Interpersonal Messaging Service (IPMS), making use of a store and
forward Message Transfer Service. It is expected that this standard
will be implemented very widely. This document describes a set of
mappings which will enable interworking between systems operating the
X.400 protocols and systems using RFC-822 mail protocol or protocols
derived from RFC-822. This RFC suggests a proposed protocol for the
ARPA-Internet community, and requests discussion and suggestions for
improvements.
986 Callon Jun 86 Working Draft -- Guidelines for the Use
of Internet-IP addressing in the ISO
Connectionless-Mode Network Protocol
This RFC suggests a method to allow the existing IP addressing,
including the IP protocol field, to be used for the ISO Connectionless
Network Protocol (CLNP). This is a draft solution to one of the
problems inherent in the use of "ISO-grams" in the DOD Internet.
Related issues will be discussed in subsequent RFCs. This RFC suggests
a proposed protocol for the ARPA-Internet community, and requests
discussion and suggestions for improvements.
985 Mills May 86 Requirements for Internet Gateways
This RFC summarizes the requirements for gateways to be used on networks
supporting the DARPA Internet protocols. While it applies specifically
to National Science Foundation research programs, the requirements are
stated in a general context and are believed applicable throughout the
Internet community. The purpose of this document is to present guidance
for vendors offering products that might be used or adapted for use in
an Internet application. It enumerates the protocols required and gives
references to RFCs and other documents describing the current
specification.
984 Clark May 86 PCMAIL: A Distributed Mail System for
Personal Computers
This document is a preliminary discussion of the design of a
personal-computer-based distributed mail system. Pcmail is a
distributed mail system that provides mail service to an arbitrary
number of users, each of which owns one or more personal computers
(PCs). The system is divided into two halves. The first consists of a
single entity called the "repository". The repository is a storage
center for incoming mail. Mail for a Pcmail user can arrive externally
from the Internet or internally from other repository users. The
repository also maintains a stable copy of each user's mail state. The
repository is therefore typically a computer with a large amount of disk
storage. It is published for discussion and comment, and does not
constitute a standard. As the proposal may change, implementation of
this document is not advised. See RFC-993.

RFC 999 March 1987
983 Cass Apr 86 ISO Transport Services on Top of the
TCP
This memo describes a proposed protocol standard for the ARPA Internet
community. The CCITT and the ISO have defined various session,
presentation, and application recommendations which have been adopted by
the international community and numerous vendors. To the largest extent
possible, it is desirable to offer these higher level services directly
in the ARPA Internet, without disrupting existing facilities. This
permits users to develop expertise with ISO and CCITT applications which
previously were not available in the ARPA Internet. The intention is
that hosts in the ARPA-Internet that choose to implement ISO TSAP
services on top of the TCP be expected to adopt and implement this
standard. Suggestions for improvement are encouraged.
982 ANSI Apr 86 Guidelines for the Specification of the
Structure of the Domain Specific Part
(DSP) of the ISO Standard NSAP Address
This RFC is a draft working document of the ANSI "Guidelines for the
Specification of the Structure of the Domain Specific Part (DSP) of the
ISO Standard NSAP Address". It provides guidance to private address
administration authorities on preferred formats and semantics for the
Domain Specific Part (DSP) of an NSAP address. This RFC specifies the
way in which the DSP may be constructed so as to facilitate efficient
address assignment. This RFC is for informational purposes only and its
distribution is unlimited and does not specify a standard of the
ARPA-Internet.
981 Mills Mar 86 An Experimental Multiple-Path Routing
Algorithm
This document introduces wiretap algorithms, a class of experimental,
multiple routing algorithms that compute quasi-optimum routes for
stations sharing a packet-radio broadcast channel. The primary route (a
minimum-distance path), and additional paths ordered by distance, which
serve as alternate routes should the primary route fail, are computed.
This prototype is presented as an example of a class of routing
algorithms and data-base management techniques that may find wider
application in the Internet community. Discussions and suggestions for
improvements are welcomed.
980 Jacobsen Mar 86 Protocol Document Order Information
This RFC indicates how to obtain various protocol documents used in the
DARPA research community. Included is an overview of the new 1985 DDN
Protocol Handbook and available sources for obtaining related documents
(such as DOD, ISO, and CCITT).

RFC 999 March 1987
979 Malis Mar 86 PSN End-to-End Functional Specification
This memo is an updated version of BBN Report 5775, "End-to-End
Functional Specification and describes important changes to the
functionality of the interface between a Host and the PSN, and should be
carefully reviewed by anyone involved in supporting a host on either the
ARPANET or MILNET". The new End-to-End protocol (EE) is being developed
in order to correct a number of deficiencies in the old EE, to improve
its performance and overall throughput, and to better equip the Packet
Switch Node (PSN, also known as the IMP) to support its current and
anticipated host population.
978 Reynolds Feb 86 Voice File Interchange Protocol (VFIP)
The purpose of the Voice File Interchange Protocol (VFIP) is to permit
the interchange of various types of speech files between different
systems in the ARPA-Internet community. Suggestions for improvement are
encouraged.
977 Kantor Feb 86 Network News Transfer Protocol
NNTP specifies a protocol for the distribution, inquiry, retrieval, and
posting of news articles using a reliable stream-based transmission of
news among the ARPA-Internet community. NNTP is designed so that news
articles are stored in a central database allowing a subscriber to
select only those items he wishes to read. Indexing, cross-referencing,
and expiration of aged messages are also provided. This RFC suggests a
proposed protocol for the ARPA-Internet community, and requests
discussion and suggestions for improvements.
976 Horton Feb 86 UUCP Mail Interchange Format Standard
This document defines the standard format for the transmission of mail
messages between computers in the UUCP Project. It does not however,
address the format for storage of messages on one machine, nor the lower
level transport mechanisms used to get the date from one machine to the
next. It represents a standard for conformance by hosts in the UUCP
zone.
975 Mills Feb 86 Autonomous Confederations
This RFC proposes enhancements to the Exterior Gateway Protocol (EGP) to
support a simple, multiple-level routing capability while preserving the
robustness features of the current EGP model. The enhancements
generalize the concept of core system to include multiple communities of
autonomous systems, called autonomous confederations. Discussion and
suggestions for improvement are requested.
Westine & Postel [Page 6]
RFC 999 March 1987
974 Partridge Jan 86 Mail Routing and the Domain System
This RFC presents a description of how mail systems on the Internet are
expected to route messages based on information from the domain system.
This involves a discussion of how mailers interpret MX RRs, which are
used for message routing.
973 Mockapetris Jan 86 Domain System Changes and Observations
This RFC documents updates to Domain Name System specifications RFC-882
and RFC-883, suggests some operational guidelines, and discusses some
experiences and problem areas in the present system.
972 Wancho Jan 86 Password Generator Protocol
This RFC specifies a standard for the ARPA Internet community. The
Password Generator Service (PWDGEN) provides a set of six randomly
generated eight-character "words" with a reasonable level of
pronounceability, using a multi-level algorithm. Hosts on the ARPA
Internet that choose to implement a password generator service are
expected to adopt and implement this standard.
971 DeSchon Dec 85 A Survey of Data Representation
Standards
This RFC is a comparison of several data representation standards that
are currently in use. The standards discussed are the CCITT X.409
recommendation, the NBS Computer Based Message System (CBMS) standard,
DARPA Multimedia Mail system, the Courier remote procedure call
protocol, and the SUN Remote Procedure Call package. No proposals in
this document are intended as standards for the ARPA-Internet at this
time. Rather, it is hoped that a general consensus will emerge as to
the appropriate approach to a data representation standard, leading
eventually to the adoption of an ARPA-Internet standard.
970 Nagle Dec 85 On Packet Switches With Infinite
Storage
The purpose of this RFC is to focus discussion on a particular problem
in the ARPA-Internet and possible methods of solution. Most prior work
on congestion in datagram systems focuses on buffer management. In this
memo the case of a packet switch with infinite storage is considered.
Such a packet switch can never run out of buffers. It can, however,
still become congested. The meaning of congestion in an
infinite-storage system is explored. An unexpected result is found that
shows a datagram network with infinite storage, first-in-first-out
queuing, at least two packet switches, and a finite packet lifetime
will, under overload, drop all packets. By attacking the problem of
congestion for the infinite-storage case, new solutions applicable to
switches with finite storage may be found. No proposed solutions this
document are intended as standards for the ARPA-Internet at this time.
Westine & Postel [Page 7]
RFC 999 March 1987
969 Clark Dec 85 NETBLT: A Bulk Data Transfer Protocol
This RFC suggests a proposed protocol for the ARPA-Internet community,
and requests discussion and suggestions for improvements. This is a
preliminary discussion of the Network Block Transfer (NETBLT) protocol.
NETBLT is intended for the rapid transfer of a large quantity of data
between computers. It provides a transfer that is reliable and flow
controlled, and is structured to provide maximum throughput over a wide
variety of networks. This description is published for discussion and
comment, and does not constitute a standard. As the proposal may
change, implementation of this document is not advised. See RFC-998.
968 Cerf Dec 85 'Twas the Night Before Start-up'
This memo discusses problems that arise and debugging techniques used in
bringing a new network into operation.
967 Padlipsky Dec 85 All Victims Together
This RFC proposes a new set of RFCs on how the networking code is
integrated with various operating systems. It appears that this topic
has not received enough exposure in the literature. Comments and
suggestions are encouraged.
966 Deering Dec 85 A Multicast Extension to the Internet
Protocol
This RFC defines a model of service for Internet multicasting and
proposes an extension to the Internet Protocol (IP) to support such a
multicast service. Discussion and suggestions for improvements are
requested. See RFC-988.
965 Aguilar Dec 85 A Format for a Graphical Communication
Protocol
This RFC describes the requirements for a graphical format on which to
base a graphical on-line communication protocol, and proposes an
Interactive Graphical Communication Format using the GKSM session
metafile. We hope this contribution will encourage the discussion of
multimedia data exchange and the proposal of solutions.
964 Sidhu Nov 85 Some Problems with the Specification of
the Military Standard Transmission
Control Protocol
The purpose of this RFC is to provide helpful information on the
Military Standard Transmission Control Protocol (MIL-STD-1778) so that
one can obtain a reliable implementation of this protocol standard.
This note points out three errors with this specification. This note
also proposes solutions to these problems.
Westine & Postel [Page 8]
RFC 999 March 1987
963 Sidhu Nov 85 Some Problems with the Specification of
the Military Standard Internet Protocol
The purpose of this RFC is to provide helpful information on the
Military Standard Internet Protocol (MIL-STD-1777) so that one can
obtain a reliable implementation of this protocol. This paper points
out several problems in this specification. This note also proposes
solutions to these problems.
962 Padlipsky Nov 85 TCP-4 Prime
This memo is in response to Bob Braden's call for a transaction oriented
protocol (RFC-955), and continues the discussion of a possible
transaction oriented transport protocol. This memo does not propose a
standard.
961 Reynolds Dec 85 Official ARPA-Internet Protocols
This memo identifies the documents specifying the official protocols
used in the Internet, and comments on any revisions or changes planned.
This edition of the Official Protocols updates and obsoletes RFC-944.
This memo is an official status report on the protocols used in the
ARPA-Internet community. See RFC-991.
960 Reynolds Dec 85 Assigned Numbers
This memo documents the currently assigned values from several series of
numbers used in network protocol implementations. This edition of
Assigned Numbers updates and obsoletes RFC-943. This memo is an
official status report on the numbers used in protocols in the
ARPA-Internet community. See RFC-990 and 997.
959 Postel Oct 85 File Transfer Protocol (FTP)
This memo is the official specification of the File Transfer Protocol
(FTP) for the DARPA Internet community. The primary intent is to
clarify and correct the documentation of the FTP specification, not to
change the protocol. The following new optional commands are included
in this edition of the specification: Change to Parent Directory
(CDUP), Structure Mount (SMNT), Store Unique (STOU), Remove Directory
(RMD), Make Directory (MKD), Print Directory (PWD), and System (SYST).
Note that this specification is compatible with the previous edition.
958 Mills Sep 85 Network Time Protocol (NTP)
This document describes the Network Time Protocol (NTP), a protocol for
synchronizing a set of network clocks using a set of distributed clients
and servers. NTP is built on the User Datagram Protocol (UDP), which
provides a connectionless transport mechanism. It is evolved from the
Time Protocol and the ICMP Timestamp message and is a suitable
replacement for both. This RFC suggests a proposed protocol for the
Westine & Postel [Page 9]
RFC 999 March 1987
ARPA-Internet community, and requests discussion and suggestions for
improvements.
957 Mills Sep 85 Experiments in Network Clock
Synchronization
This RFC discusses some experiments in clock synchronization in the
ARPA-Internet community, and requests discussion and suggestions for
improvements. One of the services frequently neglected in computer
network design is a high-quality, time-of-day clock capable of
generating accurate timestamps with small errors compared to one-way
network delays. Such a service would be useful for tracing the progress
of complex transactions, synchronizing cached data bases, monitoring
network performance and isolating problems. In this memo one such clock
service design will be described and its performance assessed. This
design has been incorporated as an integral part of the network routing
and control protocols of the Distributed Computer Network (DCnet)
architecture.
956 Mills Sep 85 Algorithms for Synchronizing Network
Clocks
This RFC discussed clock synchronization algorithms for the
ARPA-Internet community, and requests discussion and suggestions for
improvements. The recent interest within the Internet community in
determining accurate time from a set of mutually suspicious network
clocks has been prompted by several occasions in which errors were found
in usually reliable, accurate clock servers after thunderstorms which
disrupted their power supply. To these sources of error should be added
those due to malfunctioning hardware, defective software and operator
mistakes, as well as random errors in the mechanism used to set and
synchronize clocks. This report suggests a stochastic model and
algorithms for computing a good estimator from time-offset samples
measured between clocks connected via network links. Included in this
report are descriptions of certain experiments which give an indication
of the effectiveness of the algorithms.
955 Braden Sep 85 Towards a Transport Service for
Transaction Processing Applications
The DoD Internet protocol suite includes two alternative transport
service protocols, TCP and UDP, which provide virtual circuit and
datagram service, respectively. These two protocols represent points in
the space of possible transport service attributes which are quite "far
apart". We want to examine an important class of applications, those
which perform what is often called "transaction processing". We will
see that the communication needs for these applications fall into the
gap "between" TCP and UDP -- neither protocol is very appropriate.
This RFC is concerned with the possible design of one or more new
protocols for the ARPA-Internet, to support kinds of applications which
are not well supported at present. The RFC is intended to spur
Westine & Postel [Page 10]
RFC 999 March 1987
discussion in the Internet research community towards the development of
new protocols and/or concepts, in order to meet these unmet application
requirements. It does not represent a standard, nor even a concrete
protocol proposal.
954 Harrenstien Oct 85 NICNAME/WHOIS
This RFC is the official specification of the NICNAME/WHOIS protocol.
This memo describes the protocol and the service. This is an update of
RFC-812.
953 Harrenstien Oct 85 Hostname Server
This RFC is the official specification of the Hostname Server Protocol.
This edition of the specification includes minor revisions to RFC-811
which brings it up to date.
952 Harrenstien Oct 85 DoD Internet Host Table Specification
This RFC is the official specification of the format of the Internet
Host Table. This edition of the specification includes minor revisions
to RFC-810 which brings it up to date.
951 Croft Sep 85 Bootstrap Protocol (BOOTP)
This RFC describes an IP/UDP bootstrap protocol (BOOTP) which allows a
diskless client machine to discover its own IP address, the address of a
server host, and the name of a file to be loaded into memory and
executed. The bootstrap operation can be thought of as consisting of
TWO PHASES. This RFC describes the first phase, which could be labeled
`address determination and bootfile selection'. After this address and
filename information is obtained, control passes to the second phase of
the bootstrap where a file transfer occurs. The file transfer will
typically use the TFTP protocol, since it is intended that both phases
reside in PROM on the client. However BOOTP could also work with other
protocols such as SFTP or FTP. This RFC suggests a proposed protocol
for the ARPA-Internet community, and requests discussion and suggestions
for improvements.
950 Mogul Aug 85 Internet Standard Subnetting Procedure
This memo discusses the utility of "subnets" of Internet networks, which
are logically visible sub-sections of a single Internet network. For
administrative or technical reasons, many organizations have chosen to
divide one Internet network into several subnets, instead of acquiring a
set of Internet network numbers. This memo specifies procedures for the
use of subnets. These procedures are for hosts (e.g., workstations).
The procedures used in and between subnet gateways are not fully
described. Important motivation and background information for a
subnetting standard is provided in RFC-940. This RFC specifies a
protocol for the ARPA-Internet community. If subnetting is implemented
it is strongly recommended that these procedures be followed.
9Westine & Postel [Page 11]
RFC 999 March 1987
949 Padlipsky Jul 85 FTP Unique-Named Store Command
There are various contexts in which it would be desirable to have an FTP
command that had the effect of the present STOR but rather than
requiring the sender to specify a file name istead caused the resultant
file to have a unique name relative to the current directory. This
RFC proposes an extension to the File Transfer Protocol for the
ARPA-Internet community, and requests discussion and suggestions for
improvements. See RFC-959.
948 Winston Jun 85 Two Methods for the Transmission of IP
Datagrams Over IEEE 802.3 Networks
This RFC describes two methods of encapsulating Internet Protocol (IP)
datagrams on an IEEE 802.3 network. This RFC suggests a proposed protocol
for the ARPA-Internet community, and requests discussion and suggestions
for improvements.
947 Lebowitz Jun 85 Multi-Network Broadcasting Within the
Internet
This RFC describes the extension of a network's broadcast domain to
include more than one physical network through the use of a broadcast
packet repeater.
946 Nedved May 85 Telnet Terminal Location Number Option
Many systems provide a mechanism for finding out where a user is logged
in from usually including information about telephone extension and
office occupants names. The information is useful for physically
locating people and/or calling them on the phone. In 1982 CMU designed
and implemented a terminal location database and modified existing
network software to handle a 64-bit number called the Terminal Location
Number (or TTYLOC). It now seems appropriate to incorporate this
mechanism into the TCP-based network protocol family. The mechanism is
not viewed as a replacement for the Terminal Location Telnet Option
(SEND-LOCATION) but as a shorthand mechansim for communicating terminal
location information between hosts in a localized community. This RFC
proposes a new option for Telnet for the ARPA-Internet community, and
requests discussion and suggestions for improvements.
945 Postel May 85 A DoD Statement on the NRC Report
In May 1983 the National Research Council (NRC) was asked jointly by DoD
and NBS to study the issues and recommend a course of action. The final
report of the NRC committee was published in February 1985 (see
RFC-942). The enclosed letter is from Donald C. Latham (ASDC3I) to DCA
transmitting the NRC report and requesting specific actions relative to
the recommendations of the report. This RFC reproduces a letter from the
Assistant Secretary of Defense for Command, Control, Communications, and
Intelligence (ASDC3I) to the Director of the Defense Communications Agency
(DCA). This letter is distributed for information only.

This Network Working Group Request for Comments documents the currently
assigned values from several series of numbers used in network protocol
implementations. This RFC will be updated periodically, and in any case
current information can be obtained from Joyce Reynolds. The assignment
of numbers is also handled by Joyce. If you are developing a protocol
or application that will require the use of a link, socket, port,
protocol, network number, etc., please contact Joyce to receive a number
assignment. This memo is an official status report on the numbers used
in protocols in the ARPA-Internet community. See RFC-990 and 997.
942 NRC Feb 85 Transport Protocols for Department of
Defense Data Networks
This RFC reproduces the National Research Council report resulting from
a study of the DoD Internet Protocol (IP) and Transmission Control
Protocol (TCP) in comparison with the ISO Internet Protocol (ISO-IP) and
Transport Protocol level 4 (TP-4).
941 ISO Apr 85 Addendum to the Network Service
Definition Covering Network Layer
Addressing
This Addendum to the Network Service Definition Standard, ISO 8348,
defines the abstract syntax and semantics of the Network Address
(Network Service Access Point Address). The Network Address defined in
this Addendum is the address that appears in the primitives of the
connection-mode Network Service as the calling address, called address,
and responding address parameters, and in the primitives of the
connectionless-mode Network Service as the source address and
destination address parameters. This document is distributed as an RFC
for information only. It does not specify a standard for the ARPA-Internet.

940 GADS Apr 85 Toward an Internet Standard Scheme for
Subnetting
Several sites now contain a complex of local links connected to the
Internet via a gateway. The details of the internal connectivity are of
little interest to the rest of the Internet. One way of organizing
these local complexes of links is to use the same strategy as the
Internet uses to organize networks, that is, to declare each link to be
an entity (like a network) and to interconnect the links with devices
that perform routing functions (like gateways). This general scheme is
called subnetting, the individual links are called subnets, and the
connecting devices are called subgateways (or bridges, or gateways).
This RFC discusses standardizing the protocol used in subnetted
environments in the ARPA-Internet.
939 NRC Feb 85 Executive Summary of the NRC Report on
Transport Protocols for Department of
Defense Data Networks
This RFC reproduces the material from the "front pages" of the National
Research Council report resulting from a study of the DOD Internet
Protocol (IP) and Transmission Control Protocol (TCP) in comparison with
the ISO Internet Protocol (ISO-IP) and Transport Protocol level 4
(TP-4). The point of this RFC is to make the text of the Executive
Summary widely available in a timely way. The order of presentation has
been altered, and the pagination changed. This RFC is distributed for
information only. This RFC does not establish any policy for the DARPA
research community or the DDN operational community.
938 Miller Feb 85 Internet Reliable Transaction Protocol
Functional and Interface Specification
This RFC is being distributed to members of the DARPA research community
in order to solicit their reactions to the proposals contained in it.
While the issues discussed may not be directly relevant to the research
problems of the DARPA community, they may be interesting to a number of
researchers and implementors. This RFC suggests a proposed protocol for
the ARPA-Internet community, and requests discussion and suggestions for
improvements.
937 Reynolds Feb 85 Post Office Protocol - Version 2
This RFC suggests a simple method for workstations to dynamically access
mail from a mailbox server. This RFC specifies a proposed protocol for
the ARPA-Internet community, and requests discussion and suggestions for
improvement. This memo is a revision of RFC-918.

936 Karels Feb 85 Another Internet Subnet Addressing
Scheme
There have been several proposals for schemes to allow the use of a
single Internet network number to refer to a collection of physical
networks under common administration which are reachable from the rest
of the Internet by a common route. Such schemes allow a simplified view
of an otherwise complicated topology from hosts and gateways outside of
this collection. They allow the complexity of the number and type of
these networks, and routing to them, to be localized. Additions and
changes in configuration thus cause no detectable change, and no
interruption of service, due to slow propagation of routing and other
information outside of the local environment. These schemes also
simplify the administration of the network, as changes do not require
allocation of new network numbers for each new cable installed. This
proposal discusses an alternative scheme, one that has been in use at
the University of California, Berkeley since April 1984. This RFC
suggests a proposed protocol for the ARPA-Internet community, and
requests discussion and suggestions for improvements.
935 Robinson Jan 85 Reliable Link Layer Protocols
This RFC discusses protocols proposed recently in RFCs 914 and 916, and
suggests a proposed protocol that could meet the same needs addressed in
those memos. The stated need is reliable communication between two
programs over a full-duplex, point-to-point communication link, and in
particular the RFCs address the need for such communication over an
asynchronous link at relatively low speeds. The suggested protocol uses
the methods of existing national and international data link layer
standards. This RFC suggests a proposed protocol for the ARPA-Internet
community, and requests discussion and suggestions for improvements.
934 Rose Jan 85 Proposed Standard for Message
Encapsulation
This memo concerns itself with message forwarding. Forwarding can be
thought of as encapsulating one or more messages inside another.
Although this is useful for transfer of past correspondence to new
recipients, without a decapsulation process (which this memo terms
"bursting"), the forwarded messages are of little use to the recipients
because they can not be distributed, forwarded, replied-to, or otherwise
processed as separate individual messages. In order to burst a message
it is necessary to know how the component messages were encapsulated in
the draft. At present there is no unambiguous standard for interest
group digests. This RFC proposes a proposed protocol for the
ARPA-Internet community, and requests discussion and suggestions for
improvements.

RFC 999 March 1987
933 Silverman Jan 85 Output Marking Telnet Option
This proposed option would allow a Server-Telnet to send a banner to a
User-Telnet so that this banner would be displayed on the workstation
screen independently of the application software running in the
Server-Telnet.
932 Clark Jan 85 A Subnetwork Addressing Scheme
This RFC proposes an alternative addressing scheme for subnets which, in
most cases, requires no modification to host software whatsoever. The
drawbacks of this scheme are that the total number of subnets in any one
network are limited, and that modification is required to all gateways.
931 StJohns Jan 85 Authentication Server
This RFC suggests a proposed protocol for the ARPA-Internet community,
and requests discussion and suggestions for improvements. This is the
second draft of this proposal (superseding RFC-912) and incorporates a
more formal description of the syntax for the request and response
dialog, as well as a change to specify the type of user identification
returned.
930 Solomon Jan 85 Telnet Terminal Type Option
This RFC specifies a standard for the ARPA Internet community. Hosts on
the ARPA Internet that exchange terminal type information within the
Telnet protocol are expected to adopt and implement this standard. This
standard supersedes RFC-884. The only change is to specify that the
TERMINAL-TYPE IS sub-negotiation should be sent only in response to the
TERMINAL-TYPE SEND sub-negotiation.
929 Lilienkamp Dec 84 Proposed Host-Front End Protocol
The Host-Front End Protocol introduced in RFC-928 is described in detail
in this memo. The first order of business is to declare that THIS IS A
PROPOSAL, NOT A FINAL STANDARD, and the second order of business is to
request that any readers of these documents who are able to do test
implementations (a) do so and (b) coordinate their efforts with the author.
This RFC suggests a proposed protocol for the ARPA-Internet community, and
requests discussion and suggestions for improvements.
928 Padlipsky Dec 84 Introduction to Proposed DOD Standard
H-FP
The broad outline of the Host-Front End Protocol introduced here and
described in RFC-929 is the result of the deliberations of a number of
experienced H-FP designers, who sat as a committee of the DoD Protocol
Standards Technical Panel. It is the intent of the designers that the
protocol be subjected to multiple test implementations and probable
iteration before being agreed upon as any sort of "standard".
Westine & Postel [Page 16]
RFC 999 March 1987
Therefore, the first order of business is to declare that THIS IS A
PROPOSAL, NOT A FINAL STANDARD, and the second order of business is to
request that any readers of these documents who are able to do test
implementations (a) do so and (b) coordinate their efforts with the
author. This RFC suggests a proposed protocol for the ARPA-Internet
community, and requests discussion and suggestions for improvements.
927 Anderson Dec 84 TACACS User Identification Telnet
Option
The following is the description of a TELNET option designed to
facilitate double login avoidance. It is intended primarily for TAC
connections to target hosts on behalf of TAC users, but it can be used
between any two consenting hosts. For example, all hosts at one site
(e.g., BBN) can use this option to avoid double login when TELNETing to
one another. This RFC suggests a proposed protocol for the ARPA-Internet
community, and requests discussion and suggestions for improvements.
926 ISO Dec 84 Protocol for Providing the
Connectionless-Mode Network Services
This note is the draft ISO protocol roughly similar to the DOD Internet
Protocol. This document has been prepared by retyping the text of ISO
DIS 8473 of May 1984, which is currently undergoing voting within ISO as
a Draft International Standard (DIS). This document is distributred as
an RFC for information only. It does not specify a standard for the
ARPA-Internet.
925 Postel Oct 84 Multi-LAN Address Resolution
The problem of treating a set of local area networks (LANs) as one
Internet network has generated some interest and concern. It is
inappropriate to give each LAN within an site a distinct Internet
network number. It is desirable to hide the details of the
interconnections between the LANs within an site from people, gateways,
and hosts outside the site. The question arises on how to best do this,
and even how to do it at all. In RFC-917 Jeffery Mogul makes a case for
the use of "explicit subnets" in a multi-LAN environment. The explicit
subnet scheme is a call to recursively apply the mechanisms the Internet
uses to manage networks to the problem of managing LANs within one
network. In this note I urge another approach: the use of "transparent
subnets" supported by a multi-LAN extension of the Address Resolution
Protocol. This RFC suggests a proposed protocol for the ARPA-Internet
community, and requests discussion and suggestions for improvements.
924 Reynolds Oct 84 Official ARPA-Internet Protocols
This RFC identifies the documents specifying the official protocols used
in the Internet. This edition of Official ARPA-Internet Protocols
obsoletes RFC-900 and earlier editions. This memo is an official status
report on the protocols used in the ARPA-Internet community. See RFC-991.
Westine & Postel [Page 17]
RFC 999 March 1987
923 Reynolds Oct 84 Assigned Numbers
This RFC documents the currently assigned values from several series of
numbers used in network protocol implementations. This edition of
Assigned Numbers obsoletes RFC-900 and earlier editions. This memo is
an official status report on the numbers used in protocols in the
ARPA-Internet community. See RFC-990, and 997.
922 Mogul Oct 84 Broadcasting Internet Datagrams in the
Presence of Subnets
We propose simple rules for broadcasting Internet datagrams on local
networks that support broadcast, for addressing broadcasts, and for how
gateways should handle them. This RFC suggests a proposed protocol for
the ARPA-Internet community, and requests discussion and suggestions for
improvements.
921 Postel Oct 84 Domain Name System Implementation
Schedule - Revised
This memo is a policy statement on the implementation of the Domain
Style Naming System in the Internet. This memo is an update of RFC-881,
and RFC-897. This is an official policy statement of the IAB and the
DARPA. The intent of this memo is to detail the schedule for the
implementation for the Domain Style Naming System. The explanation of
how this system works is to be found in the references.
920 Postel Oct 84 Domain Requirements
This memo states the requirements on establishing a Domain, and
introduces the limited set of top level domains. This memo is a policy
statement on the requirements of establishing a new domain in the
ARPA-Internet and the DARPA research community. This is an official
policy statement of the IAB and the DARPA.
919 Mogul Oct 84 Broadcasting Internet Datagrams
This RFC proposes simple rules for broadcasting Internet datagrams on
local networks that support broadcast, for addressing broadcasts, and
for how gateways should handle them. This RFC suggests a proposed
protocol for the ARPA-Internet community, and requests discussion and
suggestions for improvements.
918 Reynolds Oct 84 Post Office Protocol (POP)
This RFC suggests a simple method for workstations to dynamically access
mail from a mailbox server. The intent of the Post Office Protocol
(POP) is to allow a user's workstation to access mail from a mailbox
server. It is expected that mail will be posted from the workstation to
the mailbox server via the Simple Mail Transfer Protocol (SMTP). This
RFC specifies a proposed protocol for the ARPA-Internet community, and
Westine & Postel [Page 18]
RFC 999 March 1987
requests discussion and suggestions for improvement. The status of this
protocol is experimental, and this protocol is dependent upon TCP.
917 Mogul Oct 84 Internet Subnets
This memo discusses subnets and proposes procedures for the use of
subnets, including approaches to solving the problems that arise,
particularly that of routing. A subnet of an Internet network is a
logically visible sub-section of a single Internet network. For
administrative or technical reasons, many organizations have chosen to
divide one Internet network into several subnets, instead of acquiring a
set of Internet network numbers. This RFC suggests a proposed protocol
for the ARPA-Internet community, and requests discussion and suggestions
for improvements.
916 Finn Oct 84 Reliable Asynchronous Transfer Protocol
(RATP)
This RFC suggests a proposed protocol for the ARPA-Internet community,
and requests discussion and suggestions for improvements. This paper
proposes and specifies a protocol which allows two programs to reliably
communicate over a communication link. It ensures that the data entering
one end of the link if received arrives at the other end intact and
unaltered. The protocol, named RATP, is designed to operate over a full
duplex point-to-point connection. It contains some features which tailor
it to the RS-232 links now in common use.
915 Elvy Dec 84 Network Mail Path Service
This RFC proposed a new service for the ARPA-Internet community and
requests discussion and suggestions for improvements. The network mail
path service fills the current need of people to determine mailbox
addresses for hosts that are not part of the ARPA-Internet but can be
reached by one or more relay hosts that have Unix to Unix Copy (UUCP)
mail, CSNET mail, MAILNET mail, BITNET mail, etc. Anyone can use the
service if they have TCP/TELENET to one of the hosts with a mail path server.
914 Farber Sep 84 A Thinwire Protocol
This RFC focuses discussion on the particular problems in the
ARPA-Internet of low speed network interconnection with personal
computers, and possible methods of solution. None of the proposed
solutions in this document are intended as standards for the
ARPA-Internet. Rather, it is hoped that a general consensus will emerge
as to the appropriate solution to the problems, leading eventually to
the adoption of standards.
Westine & Postel [Page 19]
RFC 999 March 1987
913 Lottor Sep 84 Simple File Transfer Protocol
This memo describes a proposed Simple File Transfer Protocol (SFTP). It
fills the need of people wanting a protocol that is more useful than
TFTP but easier to implement (and less powerful) than FTP. SFTP
supports user access control, file transfers, directory listing,
directory changing, file renaming and deleting. Discussion of this
proposal is encouraged, and suggestions for improvements may be sent to
the author.
912 StJohns Sep 84 Authentication Service
This memo describes a proposed authentication protocol for verifying the
identity of a user of a TCP connection. Given a TCP port number pair,
it returns a character string which identifies the owner of that
connection on the server's system. Suggested uses include automatic
identification and verification of a user during an FTP session,
additional verification of a TAC dial up user, and access verification
for a generalized network file server.
911 Kirton Aug 84 EGP Gateway under Berkeley Unix 4.2
This memo describes an implementation of the Exterior Gateway Protocol
(EGP) (in that sense it is a status report). The memo also discusses
some possible extentions and some design issues (in that sense it is an
invitation for further discussion).
910 Forsdick Aug 84 Multimedia Mail Meeting Notes
This memo is a report on a meeting about the experimental multimedia
mail system (and in a sense a status report on that experiment). The
meeting was held at Bolt Beranek and Newman on 23-24 July 1984 to
discuss recent progress by groups who are building multimedia mail
systems and to discuss a variety of issues related to the further
development of multimedia systems. Representatives were present from
BBN, ISI, SRI and Linkabit.
909 Welles Jul 84 Loader Debugger Protocol
The Loader Debugger Protocol (LDP) is an application layer protocol for
loading, dumping, and debugging target machines from hosts in a network
environment. This RFC specifies a proposed protocol for the
ARPA-Internet and DARPA research community, and requests discussion and
suggestions for improvemts.
908 Velten Jul 84 Reliable Data Protocol
The Reliable Data Protocol (RDP) is designed to provide a reliable data
transport service for packet-based applications. This RFC specifies a
proposed protocol for the ARPA-Internet and DARPA research community,
and requests discussion and suggestions for improvemts.
Westine & Postel [Page 20]
RFC 999 March 1987
907 Storch Jul 84 Host Access Protocol Specification
This document specifies the Host Access Protocol (HAP). Although HAP
was originally designed as the network-access level protocol for the
DARPA/DCA sponsored Wideband Packet Satellite Network, it is intended
that it evolve into a standard interface SATNET and TACNET (aka MATNET)
as well as the Wideband Network. HAP is an experimental protocol, and
will undergo further revision as new capabilities are added and/or
different satellite networks are suported. Implementations of HAP
should be performed in coordination with satellite network development
and operations personnel.
906 Finlayson Jun 84 Bootstrap Loading Using TFTP
It is often convenient to be able to bootstrap a computer system from a
communications network. This RFC proposes the use of the IP TFTP
protocol for bootstrap loading in this case.
905 ISO Apr 84 ISO Transport Protocol Specification
(ISO DP 8073)
This is the current specification of the ISO Transport Protocol. This
document is the text of ISO/TC97/SC16/N1576 as corrected by
ISO/TC97/SC16/N1695. This is the specification currently being voted on
in ISO as a Draft International Standard (DIS). This document is
distributed as an RFC for your information only, it does not specify a
standard for the ARPA-Internet or DARPA research community. Our thanks
to Alex McKenzie of BBN for making this online version available.
Please note the size of this document, the file contains 258,729
characters.
904 Mills Apr 84 Exterior Gateway Protocol Formal
Specification
RFC-904 is the specification of the Exterior Gateway Protocol (EGP).
This memo updates portions of RFC-888 and RFC-827. This RFC specifies
an official protocol of the DARPA community for use between gateways of
different autonomous systems in the ARPA-Internet.
903 Finlayson Jun 84 A Reverse Address Resolution Protocol
This RFC suggests a method for workstations to dynamically find their
protocol address (e.g., their Internet Address), when they know only
their hardware address (e.g., their attached physical network address).
This RFC specifies a proposed protocol for the ARPA Internet community,
and requests discussion and suggestions for improvements.

RFC 999 March 1987
902 Postel Jul 84 ARPA-Internet Protocol Policy
The purpose of this memo is to explain how protocol standards are
adopted for the ARPA-Internet and the DARPA research community. There
are three important aspects to be discussed: the process, the
authority, and the complex relationship between the DARPA community and
the DDN community. This memo is a policy statement on how protocols
become official standards for the ARPA-Internet and the DARPA research
community. This is an official policy statement of the ICCB and the
DARPA.
901 Reynolds Jun 84 Official ARPA-Internet Protocols
This RFC identifies the documents specifying the official protocols used
in the ARPA-Internet. Annotations identify any revisions or changes
planned. This memo is an official status report on the protocols used
in the DARPA research community. See RFC-991.
900 Reynolds Jun 84 Assigned Numbers
This RFC specifies parameter values use in the Internet family of
protocols, such as network numbers, well known ports, protocol types,
and version numbers. This memo is an official status report on the
protocol parameters used in the Internet protocol system. See RFC-990
and 997.
