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.
