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.
