Request for Comments: 961 J.

Obsoletes: RFCs 944, 924, 901, 880, 840 December 1985


OFFICIAL ARPA-INTERNET


STATUS OF THIS

This memo is an official status report on the protocols used in
ARPA-Internet community. Distribution of this memo is unlimited



This RFC identifies the documents specifying the official
used in the Internet. Comments indicate any revisions or
planned

To first order, the official protocols are those in the "
Protocol Transition Workbook" (IPTW) dated March 1982. There
several protocols in use that are not in the IPTW. A few of
protocols in the IPTW have been revised. Notably, the mail
have been revised and issued as a volume titled "Internet
Protocols" dated November 1982. Telnet and the most useful
options have been revised and issued as a volume titled "
Telnet Protocol and Options" (ITP) dated June 1983. The
Transfer Protocol has been revised most recently as RFC 959 which
not yet included in any collection. Some protocols have not
revised for many years, these are found in the old "ARPANET
Handbook" (APH) dated January 1978. There is also a volume
protocol related information called the "Internet
Implementers Guide" (IPIG) dated August 1982.

This document is organized as a sketchy outline. The entries
protocols (e.g., Transmission Control Protocol). In each entry
are notes on status, specification, comments, other references
dependencies, and contact

The STATUS is one of: required, recommended, elective,
experimental

The SPECIFICATION identifies the protocol defining documents

The COMMENTS describe any differences from the specification
problems with the protocol

The OTHER REFERENCES identify documents that comment on or
on the protocol

The DEPENDENCIES indicate what other protocols are called upon
this protocol

The CONTACT indicates a person who can answer questions about
protocol

In particular, the status may be



- all hosts must implement the required protocol



- all hosts are encouraged to implement the
protocol



- hosts may implement or not the elective protocol



- hosts should not implement the experimental
unless they are participating in the experiment and
coordinated their use of this protocol with the
person,



- this is not a protocol

NETWORK

Internet Protocol --------------------------------------------- (IP

STATUS:

SPECIFICATION: RFC 791 (in IPTW

COMMENTS

This is the universal protocol of the Internet. This
protocol provides the universal addressing of hosts in
Internet

A few minor problems have been noted in this document

The most serious is a bit of confusion in the route options
The route options have a pointer that indicates which octet
the route is the next to be used. The confusion is between
phrases "the pointer is relative to this option" and "
smallest legal value for the pointer is 4". If you
confused, forget about the relative part, the pointer
at 4.

Another important point is the alternate reassembly
suggested in RFC 815.

Some changes are in the works for the security option

Note that ICMP is defined to be an integral part of IP.

include ICMP

COMMENTS

The control messages and error reports that go with
Internet Protocol

A few minor errors in the document have been noted
Suggestions have been made for additional types of
message and additional destination unreachable messages

A proposal for two additional ICMP message types is made

Address Mask Reply (A2=18). The details of these ICMP
are subject to change. Use of these ICMP types

HOST

User Datagram Protocol --------------------------------------- (UDP

STATUS:

SPECIFICATION: RFC 768 (in IPTW

COMMENTS

Provides a datagram service to applications. Adds
addressing to the IP services

The only change noted for the UDP specification is a
clarification that if in computing the checksum a padding
is used for the computation it is not transmitted or counted
the length

Transmission Control Protocol -------------------------------- (TCP

STATUS:

SPECIFICATION: RFC 793 (in IPTW

COMMENTS

Provides reliable end-to-end data stream service

Many comments and corrections have been received for the
specification document. These are primarily document
rather than protocol bugs

Event Processing Section: There are many minor corrections
clarifications needed in this section

Push: There are still some phrases in the document that give
"record mark" flavor to the push. These should be
clarified. The push is not a record mark

Urgent: Page 17 is wrong. The urgent pointer points to
last octet of urgent data (not to the first octet of non-
data).



Reynolds & Postel [Page 6]



Official ARPA-Internet Protocols RFC 961


Listening Servers: Several comments have been received
difficulties with contacting listening servers. There
be some discussion of implementation issues for servers,
some notes on alternative models of system and
organization for servers

Maximum Segment Size: The maximum segment size option
be generalized and clarified. It can be used to
increase or decrease the maximum segment size from the default
The TCP Maximum Segment Size is the IP Maximum Datagram
minus forty. The default IP Maximum Datagram Size is 576.
default TCP Maximum Segment Size is 536. For
discussion, see RFC 879.

Idle Connections: There have been questions
automatically closing idle connections. Idle connections
ok, and should not be closed. There are several cases
idle connections arise, for example, in Telnet when a user
thinking for a long time following a message from the
computer before his next input. There is no TCP "probe
mechanism, and none is needed

Queued Receive Data on Closing: There are several points
it is not clear from the description what to do about
received by the TCP but not yet passed to the user
particularly when the connection is being closed. In general
the data is to be kept to give to the user if he does a
call

Out of Order Segments: The description says that segments
arrive out of order, that is, are not exactly the next
to be processed, may be kept on hand. It should also point
that there is a very large performance penalty for not
so

User Time Out: This is the time out started on an open or
call. If this user time out occurs the user should
notified, but the connection should not be closed or the
deleted. The user should explicitly ABORT the connection if
wants to give up

if you see any problems within the linking, don't worry be happy,
this is version 0.1 of the Relevance System and you gotta expect some crappy subroutines sometimes,
just be content we did not write this in Java, which would have made this "bigger and better" HAHAHHA.
