Moving Outdated TCP Extensions and TCP-Related Documents
to Historic or Informational Status
Abstract
This document reclassifies several TCP extensions and TCP-related
documents that either have been superseded, have never seen
widespread use, or are no longer recommended for use to "Historic"
status. The affected documents are RFCs 675, 721, 761, 813, 816,
879, 896, 1078, and 6013. Additionally, this document reclassifies
RFCs 700, 794, 814, 817, 872, 889, 964, and 1071 to "Informational"
status.
Status of This Memo
This document is not an Internet Standards Track specification; it is

1. Introduction
TCP has a long history. Over time, many RFCs have accumulated that
describe aspects of the TCP protocol, implementation, and extensions.
Some of these have been superseded, are no longer recommended for
use, or have simply never seen widespread use.
Sections 6 and 7.1 of the TCP roadmap document [RFC7414] already
reclassified a number of TCP extensions as "Historic" and describes
the reasons for doing so, but it did not instruct the RFC Editor to
change the status of these RFCs in the RFC database. The purpose of
this document is to do just that.
In addition, this document reclassifies all other documents mentioned
in the TCP roadmap that currently have an "Unknown" status to either
"Historic" or "Informational".

2. Status Changes
The following two sections give a short justification why a specific
TCP extension or a TCP-related document is being reclassified as
"Historic" or "Informational". In addition, the letter code after an
RFC number indicates from which original status a particular RFC is
changed to "Historic" or "Informational" (see BCP 9 [RFC2026] for an
explanation of these categories):
S - Standards Track (Proposed Standard, Draft Standard, or
Internet Standard)
E - Experimental
I - Informational
H - Historic
B - Best Current Practice
U - Unknown (not formally defined)
For the content of the documents itself, the reader is referred
either to the corresponding RFC or, for a brief description, to the
TCP roadmap document [RFC7414].
2.1. Moving to "Historic" Status
This document changes the status of the following RFCs to "Historic"
[RFC2026]:
o [RFC675] U, "Specification of Internet Transmission Control
Program" was replaced by the final TCP specification [RFC793]
o [RFC721] U, "Out-of-Band Control Signals in a Host-to-Host
Protocol" was a proposal that was not incorporated into the final
TCP specification [RFC793]
o [RFC761] U, "DoD Standard Transmission Control Protocol" was
replaced by the final TCP specification [RFC793]
o [RFC813] U, "Window and Acknowledgement Strategy in TCP" was
incorporated into [RFC1122]
o [RFC816] U, "Fault Isolation and Recovery" was incorporated into
[RFC1122] and [RFC5461]
Zimmermann, et al. Informational [Page 3]
RFC 7805 Outdated TCP Extensions and Documents April 2016
o [RFC879] U, "The TCP Maximum Segment Size and Related Topics" was
incorporated into [RFC1122] and [RFC6691]
o [RFC896] U, "Congestion Control in IP/TCP Internetworks" was
incorporated into [RFC1122] and [RFC6633]
o [RFC1078] U, "TCP Port Service Multiplexer (TCPMUX)" should be
deprecated, because:
* It modifies the TCP connection establishment semantics by also
completing the three-way handshake when a service is not
available.
* It requires all new connections to be received on a single
port, which limits the number of connections between two
machines.
* It complicates firewall implementation and management because
all services share the same port number.
* There are very limited deployments, and these are not used in
an Internet context. (The only reported use is for SGI's Data
Migration Facility in private networks.)
o [RFC6013] E, "TCP Cookie Transactions (TCPCT)" should be
deprecated (although only published in 2011) because:
* It uses the experimental TCP option codepoints, which prohibit
a large-scale deployment.
* [RFC7413] and [TCP-EDO] are alternatives that have more "rough
consensus and running code" behind them.
* There are no known wide-scale deployments.
2.2. Moving to "Informational" Status
This document changes the status of the following RFCs to
"Informational" [RFC2026]:
o [RFC700] U, "A Protocol Experiment", which presents a field report
about the deployment of a very early version of TCP
o [RFC794] U, "Pre-emption", which recommends that operating
systems need to manage their limited resources, which may include
TCP connection state
o [RFC814] U, "Name, Addresses, Ports, and Routes", which gives
guidance on designing tables and algorithms to keep track of
various identifiers within a TCP/IP implementation
o [RFC817] U, "Modularity and Efficiency in Protocol
Implementation", which contains general implementation suggestions
Zimmermann, et al. Informational [Page 4]
RFC 7805 Outdated TCP Extensions and Documents April 2016
o [RFC872] U, "TCP-on-a-LAN", which concludes that the fear of
using TCP on a local network is unfounded
o [RFC889] U, "Internet Delay Experiments", which describes
experiments with the TCP retransmission timeout calculation
o [RFC964] U, "Some Problems with the Specification of the Military
Standard Transmission Control Protocol", which points out several
specification bugs in the US Military's MIL-STD-1778 document,
which was intended as a successor to [RFC793]
o [RFC1071] U, "Computing the Internet Checksum", which lists a
number of implementation techniques for efficiently computing the
Internet checksum
3. Security Considerations
This document introduces no new security considerations. Each RFC
listed in this document attempts to address the security
considerations of the specification it contains.
