Abstract

   This document describes the scenarios, simulation and suggestions
   for the "Centrally Control Dynamic Routing (CCDR)" architecture,
   which integrates the merit of traditional distributed protocols
   (IGP/BGP), and the power of centrally control technologies (PCE/SDN)
   to provide one feasible traffic engineering solution in various
   complex scenarios for the service provider.

   Traditional MPLS-TE solution is mainly used in static network
   planning scenario and is difficult to meet the QoS assurance
   requirements in real-time traffic network. With the emerge of SDN
   concept and related technologies, it is possible to simplify the
   complexity of distributed control protocol, utilize the global view
   of network condition, give more efficient solution for traffic
   engineering in various complex scenarios.
