        DISPATCH-Style Working Groups and the SIP Change Process

Abstract

   RFC 5727 defined several processes for the former Real-time
   Applications and Infrastructure (RAI) area.  These processes include
   the evolution of the Session Initiation Protocol (SIP) and related
   protocols, as well as the operation of the DISPATCH and SIPCORE
   working groups.  This document updates RFC 5727 to allow flexibility
   for the area and working group structure, while preserving the SIP
   change processes.  It also generalizes the DISPATCH working group
   processes so that they can be easily adopted by other working groups.

1.  Introduction

   [RFC5727] described processes for evolving and maintaining the
   Session Initiation Protocol (SIP) [RFC3261] and related technologies
   in the former Real-time Application and Infrastructure (RAI) area.
   These processes are collectively known as the "SIP Change Process".
   While areas do not normally have "charters" per se, RFC 5727
   effectively served as a charter for RAI.  The language in RFC 5727
   was tightly bound to the RAI area and to the DISPATCH and SIPCORE
   working groups.

   In 2015, The RAI area merged with the Applications (APP) area to form
   the Applications and Real-Time (ART) area.  This document updates RFC
   5727 to remove its dependency on RAI and its working group structure.
   The updates in this document do not depend on the names of the new
   area, or any specific working group.  Rather, the authors seek to
   future-proof the SIP Change Process against future reorganizations.

   RFC 5727 specified that the DISPATCH working group assesses potential
   new work for the area, and determines where such work should occur.
   DISPATCH does not itself take on such new work.  The SIPCORE working

   group is responsible for maintenance of SIP.  Other historically RAI
   area working groups develop extensions to SIP that do not change the
   core protocol, new applications of SIP, and other technologies for
   interactive communication among humans.  This document further
   generalizes the processes of the DISPATCH working group so that they
   can be applied to other areas, or to clusters of technologies within
