Abstract

   This document provides guidelines for applying or extending the MPLS
   or GMPLS ((G)MPLS) protocol suites and clarifies the IETF's (G)MPLS
   working groups' responsibility for the (G)MPLS protocols.  This
   document is directed to multi-vendor fora and Standards Development
   Organizations (SDOs) to provide an understanding of (G)MPLS work in
   the IETF and documents the requisite use of IETF review procedures
   when considering (G)MPLS applications or protocol extensions in their
   work.  This document does not modify IETF processes.

1.  Introduction

   The MPLS and GMPLS technology is developed in two main tracks in the
   IETF.  "MPLS" refers to the work done for packet switched networks,
   while "GMPLS" refers to the efforts to apply the MPLS protocols to
   all types of networks including packet and non-packet technologies.

   Though GMPLS by definition is a superset of MPLS, the term "(G)MPLS"
   is used in this document to indicate both of these tracks.  A
