Do you have a paper spec (Internet Draft or other such documentation)= so
other platforms can port this?

See =A0<= a href=3D"http://www.ietf.org/mail-archive/web/tcpm/current/msg06856.html">= http://www.ietf.org/mail-archive/web/tcpm/current/msg06856.html

Also a paper titled "TCP Fast Open" has been publi= shed at ACM/CoNEXT 2011.

Best,

Jerry

Thanks,
Dan
