This document specifies an algorithm for the generation of TCP
Initial Sequence Numbers (ISNs), such that the chances of an off-path
attacker guessing the sequence numbers in use by a target connection
are reduced.  This document revises (and formally obsoletes) RFC
1948, and takes the ISN generation algorithm originally proposed in
that document to Standards Track, formally updating RFC 793.
