A new Request for Comments is now available in online RFC libraries. RFC 9170 Title: Long-Term Viability of Protocol Extension Mechanisms Author: M. Thomson, T. Pauly Status: Informational Stream: IAB Date: December 2021 Mailbox: mt@lowentropy.net, tpauly@apple.com Pages: 17 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-iab-use-it-or-lose-it-04.txt URL: https://www.rfc-editor.org/info/rfc9170 DOI: 10.17487/RFC9170 The ability to change protocols depends on exercising the extension and version-negotiation mechanisms that support change. This document explores how regular use of new protocol features can ensure that it remains possible to deploy changes to a protocol. Examples are given where lack of use caused changes to be more difficult or costly. This document is a product of the Internet Architecture Board.
