Abstract

   This document presents Service Provider requirements for support of
   Differentiated Services (Diff-Serv)-aware MPLS Traffic Engineering
   (DS-TE).

   Its objective is to provide guidance for the definition, selection
   and specification of a technical solution addressing these
   requirements.  Specification for this solution itself is outside the
   scope of this document.

   A problem statement is first provided.  Then, the document describes
   example applications scenarios identified by Service Providers where
   existing MPLS Traffic Engineering mechanisms fall short and
   Diff-Serv-aware Traffic Engineering can address the needs.  The
   detailed requirements that need to be addressed by the technical
   solution are also reviewed.  Finally, the document identifies the
   evaluation criteria that should be considered for selection and
   definition of the technical solution.
