RFC 6247 Undeployed TCP Extensions to Historic May 2011 1. IntroductionTCP 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.
2. RFC Editor Considerations
Per this document, the RFC Editor has changed the status of the following RFCs to Historic [RFC2026]:
3. 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.
4. Security Considerations
As mentioned in [RFC4614], the TCP Extensions for Transactions (T/TCP) [RFC1379][RFC1644] are reported to have security issues [DEVIVO].
