  1. Deprecation of ICMP Source Quench messages(draft-gont-tsvwg-source-quench-00) Fernando Gont UTN/FRH IETF 79 November 7-12, 2010. Beijing, China

  2. Summary • ICMP Source Quench generation by routers already deprecated by RFC 1812 • Security implications discussed in RFC 5927 (ICMP attacks against TCP) • No TCP implementation (that I know of) currently honors ICMP Source Quenches • At the time, there was consensus in tcpm wg to formally deprecate ICMP Source Quench messages. It was suggested that this should be pursued in tsvwg. • This I-D does that: It deprecates reaction to ICMP Source Quench messages (requests that nodes ignore them)

  3. Moving forward • Adopt as wg item?
