Study Of The Construction And Optimization Of IP Network Based On Broad Band Services

Along with popularity of accessing network with broad band, the application of network games, video on-line based on broad band , the value-added application of the Internet with high speed and broad band, and the IP value-added application on the level of Telecommunication for NGN , 3G will enter a new stage of development with high speed.At the same time, the requirements for the interconnection and multiple services proposed by more and more enterprises were submitted, associating with the continual deep development of the informational processes of enterprises.The China Telecommunication should reform, optimize , even newly establish its backbone network on its telecommunication network in order to satisfy the requirements that make the ChinaNet suit the fast increment of Internet users, and hold the superiority in the aspect of IP network on the broad band Internet of China Telecommunication.The characteristics of new broad band services are the important factors and basis that decide the construction and optimization of broad band IP network. In the first, the services of MPLS VPN and NGN were described and analyzed from the viewpoint of the services of the nearest current network in this paper.Based on the current structure of network and the working situation , consulting the developing strategy of the construction of the Group of China Telecommunication, combining the current situation of the backbone net and local net, the author analyzed and described the construction of the second backbone network and the optimization about the access net of the MAN from the viewpoint of the network structure, the constitution of services, the components of key functions and the selection of techniques.Through the analysis and description, a series of methods and measures that we must take, so as to establish and optimize the distinct network layers of the object network , which can be easy to plan, manage, and maintain, were put forward by the author. The network posses the intelligent capability of services, which can identify the services, and it can perform the various service policies and QoS according to the types of services that has the capabilities of multiple...
