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.
