Long-Term Viability of Protocol Extension Mechanisms

Metadata

Publisher: IETF
Doc Type: Informational
Pages: 17
Abstract: 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.
