The IESG has received a request from the TCP Maintenance and Minor Extensions WG (tcpm) to consider the following document: - 'TCP Fast Open' <draft-ietf-tcpm-fastopen-09.txt> as Experimental RFC 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 2014-07-23. 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 an experimental TCP mechanism TCP Fast Open (TFO). TFO allows data to be carried in the SYN and SYN-ACK packets and consumed by the receiving end during the initial connection handshake, thus saving up to one full round trip time (RTT) compared to the standard TCP, which requires a three-way handshake (3WHS) to complete before data can be exchanged. However TFO deviates from the standard TCP semantics since the data in the SYN could be replayed to an application in some rare circumstances. Applications should not use TFO unless they can tolerate this issue detailed in the Applicability section. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-tcpm-fastopen/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-tcpm-fastopen/ballot/ No IPR declarations have been submitted directly on this I-D.
