The Research Of Ningxia Telecom Multi-service IP Man Bearer Network

This paper describes the situation and trend of the telecommunications development and indicates that the IP network is the future core of telecommunications multi-service bearer network. we analyzed the current data networks and the needs of Ningxia Telecom services of the bearer network to find out that,with the incoming of theTriple Play,the IP network must be developed to be able to bear multi-service. Based on that, we propose to transform and optimize the current network and build a multi-service bearer IP MAN.Then this paper introduced the the basics of IP MAN Planning,including technical requirements of the multi-service IP bearer network,basic routing protocols,MPLS/VPN, transmission technology of IP MAN, etc.Above all,we turns to focus on the optimization program of the Ningxia Telecom IP MAN.First,we got the service-access goals and bandwidth prediction according to the actual situation of the current IP bearer network of Ningxia.Second,we designed a viable building program of the network-structure and routing, service-bearing planning and network-resource planning.Finally,we have a detailed describe of deployment of the key technologies that the multi-service bearer network required in the IP MAN.This paper is only a imperfect discussion of IP MAN of Ningxia. We may be encountered much problem in the implementation process, we will constantly sum up experience and create a data communication network of quality class.
