Routing optimization for inter-domain traffic engineering under separation and mapping architecture

To resolve the scalability problem in the existing Internet, there are many researches proposing the idea of separating the Internet into two independent evolving spaces, the access network and the core network, respectively. Such separation provides us opportunities to reconsider the methods of implementation of inter-domain traffic engineering under the new network environment. Based on the existing architecture of universal network, we propose a new method for implement traffic engineering and give detailed contrast between the newly proposed method and traditional method being used in current Internet. And we give feasibility analysis of the method.
