The TCP Maintenance and Minor Extensions (tcpm) working group in the Transport Area of the IETF has been rechartered. For additional information please contact the Area Directors or the WG Chairs. TCP Maintenance and Minor Extensions (tcpm) ------------------------------------------------ Current Status: Active WG Chairs: Michael Scharf <michael.scharf@alcatel-lucent.com> Yoshifumi Nishida <nishida@sfc.wide.ad.jp> Pasi Sarolahti <pasi.sarolahti@iki.fi> Assigned Area Director: Martin Stiemerling <mls.ietf@gmail.com> Mailing list Address: tcpm@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/tcpm Archive: http://www.ietf.org/mail-archive/web/tcpm/ Charter: TCP is currently the Internet's predominant transport protocol. TCPM is the working group within the IETF that handles small TCP changes, i.e., minor extensions to TCP algorithms and protocol mechanisms. The TCPM WG serves several purposes: * The WG mostly focuses on maintenance issues (e.g., bug fixes) and modest changes to the protocol, algorithms, and interfaces that maintain TCP's utility. * The WG is a venue for moving current TCP specifications along the standards track (as community energy is available for such efforts). * The focus of the working group is TCP. In cases where small changes are directly applicable to other transports (e.g., SCTP or DCCP), the mappings to other transports may be specified alongside that for TCP, but other significant additions and changes to other transports are not in scope. TCPM also provides a venue for standardization of incremental enhancements of TCP's standard congestion control. In addition, TCPM may document alternative TCP congestion control algorithms that are known to be widely deployed, and that are considered safe for large-scale deployment in the Internet. Changes of algorithms may require additional review by the IRTF Congestion Control Research Group (ICCRG). Fundamental changes to TCP or its congestion control algorithms (e.g., departure from loss-based congestion control) will be handled by other working groups or will require rechartering. TCP's congestion control algorithms are the model followed by alternate transports (e.g., SCTP or DCCP), which are standardized in other working groups, such as the Transport Area WG (tsvwg). In the past, the IETF has worked on several documents about algorithms that are specified for multiple protocols (e.g., TCP and SCTP) in the same document. Which WG shepherds such documents will be determined on a case-by-case basis. In any case, the TCPM WG will remain in close contact with other relevant WGs working on these protocols to ensure openness and stringent review from all angles. New TCPM milestones that fall within the scope specified within the charter can be added after consensus on acceptance in the working group and approval by the responsible Area Director. Milestones: Aug 2013 - Submit document on restarting the RTO timer to the IESG for publication as an Experimental RFC Nov 2013 - Submit document on TCP support for rate-limited traffic for publication (status decided as earlier milestone) Nov 2013 - Submit document on an analysis of more detailed ECN feedback in TCP to the IESG for publication as an Informational RFC Mar 2014 - Submit revision of TCP roadmap (RFC 4614) to the IESG for publication as an Informational RFC Mar 2015 - Submit document obsoleting undeployed TCP extensions to the IESG for publication as an Informational RFC Aug 2015 - Submit document on a TCP Extended Data Offset Option to the IESG as a Proposed Standard RFC
