The IESG contact persons are Martin Duke and Magnus Westerlund. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-tcpm-rto-consider/
Technical Summary This document provides high-level guidance to design last resort time-based loss detection schemes for general use on the Internet, which can be applied to not only TCP, but also other transport protocols and applications that need their own loss detection mechanisms. This Best Current Practice document describes generic principles to update existing loss detection algorithms or to develop new ones, which may be especially useful to non- specialist implementers of applications running directly over UDP or DTLS, which therefore require custom loss detection. Working Group Summary This draft has been around for 10 years, and is in tcpm for historical reasons. It has received significant review from both tsvwg and iccrg, where relevant expertise is present. There was also a WGLC in tsvwg. Document Quality This is not a protocol, but a series of design considerations. Standardized loss detection algorithms in TCP, SCTP, and QUIC are compliant with the requirements here and widely implemented. The described principles are uncontroversial in the transport community, and most WG description was focused on correct wording of those principles. Ethan Blanton, Sally Floyd, Jana Iyengar, Shawn Ostermann, and Vern Paxson provided particularly important contributions over the years. Personnel Yoshifumi Nishida is the document shepherd. Martin Duke is responsible Area Director. There are no IANA actions.
