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.

1.  Introduction

   Internet network is composed mainly tens 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 traditional IGP protocols.  These
   distributed protocols are robust enough to support the current
   evolution of Internet but has some difficulties when the application
