Dear all,

the current version of the draft appears to be :

(as Randy's page is a bit outdated :-)

TCP does not change the port after a TCP connection has
been established. The socket is the tuple consisting of
Protocol (e.g. UDP, TCP), src address, src port, dest address, dest port,
and is valid for the lifetime of a TCP connection.
Please look at Stevens, TCP/IP Illustrated, Vol.1, which is
recommended reading, anyway.

Regards,
Andreas
