Moving Outdated TCP Extensions and TCP-related Documents to Historic and Informational Status


This document reclassifies several TCP extensions and TCP-related documents that have either been superseded, never seen widespread use, or are no longer recommended for use to Historic status. The affected RFCs are RFC 675, RFC 721, RFC 761, RFC 813, RFC 816, RFC 879, RFC 896, RFC 1078, and RFC 6013. Additionally, it reclassifies RFC 700, RFC 794, RFC 814, RFC 817, RFC 872, RFC 889, RFC 964, and RFC 1071 to Informational status.

Status of This Memo

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 Some of these have become superseded, are no longer recommended for use, or simply have never seen widespread use, respectively deployment.

Section 6 and 7.1 of the TCP Roadmap document [RFC7414] already classify a number of TCP extensions as "historic" and describes the reasons for doing so, but it does 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, it moves all remaining TCP-related documents of the TCP Roadmap document with an "unknown" status either to Historic or Informational.

2. Terminology

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. These words only have such normative significance when in ALL CAPS, not when in lower case.

3. RFC Editor Considerations

The following two sections give a short justification, why a specific TCP extension or a TCP-related document should be moved to Historic or Informational. In addition, a letter code after an RFC number indicates from what category in the RFC series a particular RFC is changed to Historic or Informational status (see BCP 9 [RFC2026] for explanation of these categories): [RFC7414].

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

3.1. Moving to Historic Status

The RFC Editor is requested to change the status of the following RFCs to Historic [RFC2026]:

3.2. Moving to Informational Status

The RFC Editor is requested to change the status of the following RFCs to Informational [RFC2026]:

4. IANA Considerations

None of the documents moved to Historic or Informational status had TCP options numbers assigned. Therefore no IANA action is required for them.

5. 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.
