This document specifies an algorithm for the generation of TCP
Initial Sequence Numbers (ISNs), such that the chances of an off-path
attacker of guessing the sequence numbers in use by a target
connection are reduced.  This document is a revision of RFC 1948, and
takes the ISN generation algorithm originally proposed in that
document to Standards Track.
