Hi all,

As mentioned today on the mic, the TCPM working group has a working group item that allows data to be carried in the SYN and SYN-ACK packets and that is consumed by the receiving end during the initial connection handshake, which is saves TCP handshakes. The document was discussed aleady extensively in TCPM and will be updated. TCPM's understanding is that it is not far away from WGLC.

The link is: http://tools.ietf.org/html/draft-ietf-tcpm-fastopen-04

In the spirit of today's session, feedback from the httpbis community would be very appreciated. Please note that this mechanism slightly changes the standard TCP semantics, as explained in the abstract:

   However TFO deviates from the standard TCP semantics in that 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,
   which is detailed in the Applicability section.

Further information can be found in Section 6 of the document.

Comments or reviews would be highly welcome. The discussion should take place on the TCPM mailing list.
