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. Document Quality The document was reviewed for quality by a large number of TCPM WG members. Personnel Mark Allman (email@example.com) was the document shepherd. Lars Eggert (firstname.lastname@example.org) reviewed the document for the IESG.
