The IESG has received a request from the TCP Maintenance and Minor Extensions WG (tcpm) to consider the following document: - 'Shared Use of Experimental TCP Options' <draft-ietf-tcpm-experimental-options-03.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-12-13. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes how the experimental TCP option codepoints can support concurrent use through the use of a magic number. This mechanism avoids the need for a coordinated registry and is backward-compatible with currently known uses. It is recommended for all new TCP options that use these codepoints. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-tcpm-experimental-options/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-tcpm-experimental-options/ballot/ No IPR declarations have been submitted directly on this I-D.
