Status of This Memo

This document is not an Internet Standards Track specification; it is published for informational purposes.

This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community.

Introduction

TCP has a long history, and several proposed TCP extensions have never seen widespread deployment. Section 5 of the TCP "roadmap" document RFC4614 already classifies a number of TCP extensions as Historic and describes the reasons for doing so, but it does not instruct the RFC Editor and IANA to change the status of these RFCs in the RFC database and the relevant IANA registries. The sole purpose of this document is to do just that. Please refer to Section 5 of RFC4614 for justification.

RFC Editor Considerations

Per this document, the RFC Editor has changed the status of the following RFCs to Historic RFC2026:

o RFC1072 on "TCP Extensions for Long-Delay Paths"

o RFC1106 and RFC1110 related to the "TCP Big Window and Nak

  Options"

o RFC1145 and RFC1146 related to the "TCP Alternate Checksum

  Options"

o RFC1379 and RFC1644 on "T/TCP -- Extensions for Transactions

  Functional Specification"

o RFC1693 on "An Extension to TCP : Partial Order Service"

IANA Considerations

IANA has marked the TCP options 6, 7, 9, 10, 11, 12, 13, 14, and 15 documented in RFC1072, RFC1146, RFC1644, and RFC1693 as "obsolete" in the "TCP Option Kind Numbers" registry [TCPOPTREG], with a reference to this RFC.

Security Considerations

As mentioned in RFC4614, the TCP Extensions for Transactions (T/TCP) RFC1379RFC1644 are reported to have security issues [DEVIVO].
