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.
