The core technology research of routing & switching in the next generation network

The next generation network is an effective measure to solve the current existing problems of the network. And the routing and exchange is the key to implement the next generation network. Thus, it is needed to study and sum up in-depth. First of all, this paper introduces characteristics of the next generation network. Then, it tells the requirement of routing and exchange. After that, it introduces a number of core technologies in the routing and exchange of the next generation network, which includes routing, large capacity switching, routing behavior model and unusual attack detection, high speed data forwarding, quality of service, routing protocols for multiport consistency testing, broadband routers exchange platform, etc. Finally, the conclusion is generated by combining with the environment at home and abroad. The description in this article covers the main content of the routing exchange in the next generation network, which is essential information for relevant personnel in research and development. Therefore, it has a certain practical significance and application value.
