1.  Introduction

TCP has a long history, and several proposed TCP extensions have never seen widespread deployment. Section 5 of the TCP "roadmap" document [RFC4614] (Duke, M., Braden, R., Eddy, W., and E. Blanton, “A Roadmap for Transmission Control Protocol (TCP) Specification Documents,” September 2006.) 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] (Duke, M., Braden, R., Eddy, W., and E. Blanton, “A Roadmap for Transmission Control Protocol (TCP) Specification Documents,” September 2006.) for justification.

2.  RFC Editor Considerations

The RFC Editor is requested to change the status of the following RFCs to Historic [RFC2026] (Bradner, S., “The Internet Standards Process -- Revision 3,” October 1996.):

• [RFC1106] (Fox, R., “TCP big window and NAK options,” June 1989.) and [RFC1110] (McKenzie, A., “Problem with the TCP big window option,” August 1989.) related to the "TCP Big Window and NAK Options"
• [RFC1145] (Zweig, J. and C. Partridge, “TCP alternate checksum options,” February 1990.) and [RFC1146] (Zweig, J. and C. Partridge, “TCP alternate checksum options,” March 1990.) related to the "TCP Alternate Checksum Options"
• [RFC1263] (O'Malley, S. and L. Peterson, “TCP Extensions Considered Harmful,” October 1991.) on "TCP Extensions Considered Harmful"
• [RFC1379] (Braden, B., “Extending TCP for Transactions -- Concepts,” November 1992.) and [RFC1644] (Braden, B., “T/TCP -- TCP Extensions for Transactions Functional Specification,” July 1994.) on "TCP Extensions for Transactions"
• [RFC1693] (Connolly, T., Amer, P., and P. Conrad, “An Extension to TCP : Partial Order Service,” November 1994.) on "TCP Partial Order Service"

3.  IANA Considerations

IANA is requested to mark the TCP options 6, 7, 9, 10, 11, 12, 13, 14 and 15 documented in [RFC1072] (Jacobson, V. and R. Braden, “TCP extensions for long-delay paths,” October 1988.), [RFC1146] (Zweig, J. and C. Partridge, “TCP alternate checksum options,” March 1990.), [RFC1644] (Braden, B., “T/TCP -- TCP Extensions for Transactions Functional Specification,” July 1994.) and [RFC1693] (Connolly, T., Amer, P., and P. Conrad, “An Extension to TCP : Partial Order Service,” November 1994.) as "obsolete" in the TCP option numbers registry [TCPOPTREG] (Internet Assigned Numbers Authority (IANA), “TCP Option Kind Numbers,” .), with a reference to this RFC.

(None of the other documents moved to Historic status had TCP options numbers assigned; no IANA action is therefore required for them.)

4.  Security Considerations

This document has no known security implications.
