Technical Summary
The TCP specification calls for calls for ICMP soft errors to be
treated as transient and therefore TCP connections will not
abort in response to such messages. A widely implemented
departure from the specification has TCP stacks treating such
soft errors as hard errors and aborting connections during
connection establishment.
Working Group Summary
The WG could not arrive at consensus for changing the TCP
specification to allow ICMP soft errors to be treated as hard
errors during connection establishment. However, this change is
widely implemented. This document describes the change in an
informational way.
