        Guidelines for Considering Operations and Management of
                 New Protocols and Protocol Extensions

Abstract

   New protocols or protocol extensions are best designed with due
   consideration of the functionality needed to operate and manage the
   protocols.  Retrofitting operations and management is sub-optimal.
   The purpose of this document is to provide guidance to authors and
   reviewers of documents that define new protocols or protocol
   extensions regarding aspects of operations and management that should
   be considered.
