The Yantai CNC MAN Plan

The wide band IP MAN is a central IP network built by telecommunication company within the scope of metropolitan area, it is the city important information infrastructure.In recent years, along with the business demanding fast growth, originallying MAN less and less can satisfy the communication request of dynamic increase, its network blemish and shortage continuously express and mainly expressed in the network structure and new service support ability. Under the current situation, only use certain scientific theory and method to reform the MAN, raise multi-service and differentiated service ability, the telecommunication company then can keep to lead advantage in the vehement competition.First, This article valuate the service and network actuality of the wide band IP MAN of YanTai CNC, then put forward the necessity and possibility of the MAN reformation.Before give detailed of reformation project, introduced some related theorieses involved by MAN reformation, and makes use of these theory to analysis the MAN's actuality of YanTai CNC and put forward detailed reformation project.First is to improve the whole MAN's physical network, include core/converge layer reformation, access layer reformation and the access network reformation, in order to acquire a advanced physical network and a resonable network topology. Then carried on routing organize and IP address plan. To choose advanced routing protocol, efficiently network routing and good IP address plan ,will reduce the pressure of network and raise whole function and effect of the network. The reasonable VLAN plan make the fast deployment of each kind of new business use possible. The QoS and Traffic engineering design is important for the IP MAN, it's necessary to provide integrated service and differentiated service. After these reformation, design the realization of various service. Finally, design the MAN's security and management. The article uses the development outlook of MAN as be over.As the reformation of YanTai CNC's MAN is finished, the goal of obtain an exquisite MAN and improve multi-service ability will be achieved.
