A new Request for Comments is now available in online RFC libraries. RFC 8170 Title: Planning for Protocol Adoption and Subsequent Transitions Author: D. Thaler, Ed. Status: Informational Stream: IAB Date: May 2017 Mailbox: dthaler@microsoft.com Pages: 22 Characters: 55160 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-iab-protocol-transitions-08.txt URL: https://www.rfc-editor.org/info/rfc8170 DOI: 10.17487/RFC8170 Over the many years since the introduction of the Internet Protocol, we have seen a number of transitions throughout the protocol stack, such as deploying a new protocol, or updating or replacing an existing protocol. Many protocols and technologies were not designed to enable smooth transition to alternatives or to easily deploy extensions; thus, some transitions, such as the introduction of IPv6, have been difficult. This document attempts to summarize some basic principles to enable future transitions, and it also summarizes what makes for a good transition plan. This document is a product of the Internet Architecture Board. INFORMATIONAL: This memo provides information for the Internet community. It does not specify an Internet standard of any kind.
