      Scenarios and Simulation Results of PCE in Native IP Network
                 draft-ietf-teas-native-ip-scenarios-07

Abstract

   The requirements for the End to End(E2E) performance assurance are
   emerging within the service provider network, there are various
   solutions to meet such demands, but there is no one solution can meet
   these requirements in native IP network, especially one universal
   solution can cover intra-domain and inter-domain scenarios together.

   This document describes the scenarios and simulation results for Path
   Computation Elements (PCE) in native IP network, which integrates the
   advantage of distributed protocols, and the power of centrally
   control technologies to provide one feasible traffic engineering
   solution in various complex scenarios for the service provider.

1.  Introduction

   Service provider network is composed of thousands of routers that run
   distributed protocol to exchange the reachability information between
   them.  The path for the destination network is mainly calculated and
   controlled by the distributed protocols.  These distributed protocols
