Abstract

This document discusses requirements for the support of inter-AS MPLS Traffic Engineering (MPLS TE). Its main objective is to present a set of requirements and scenarios which would result in general guidelines for the definition, selection, and specification development for any technical solution(s) meeting these requirements and supporting the scenarios.
