Henan Communications Broadband Network Construction Plan - Broadband Ip Network Expansion Optimization

This thesis is a piece of project thesis about construction and optimization of the Henan communication broad-band networks. With the constant development of government informationization, enterprise informationization, and social informationization , there is more and more expectations to the network, which is developing towards broad-band, individualization, and diversification directions. Under such situation, in 2000 Henan Communication Corporation took the lead in constructing the IP network of broad-band, utilizing POS and MPLS technology to set up broad-band key IP network of the whole province , which satisfied subscribers' demands for the network at that time basically. But according to the constant development of the broad-band business, the subscribers' quantity is increasing constantly , and they have higher and higher requisition on transmissionspeed of the network, IP network of Henan communication ( especially the edge layer) faces heavier and heavier pressure of dilatation. Thus Henan Communication Corporation designed dilatation and optimization project of broad-band IP network for this reason. This thesis is designed to satisfy that demand of Henan Communication Corporation, which focuses on IP network dilatation and optimization. The thesis contains five parts. The first part describes the present problems of Henan communication broad-band network . The second part tries to solve these problems from the following several respects, and raises some engineering construction scheme:1. engineering constructions feasibility expound;2. analysis and forecast of the future businesses . Analysis and prediction of the broad-band business takes a large amount of space in this part , which have grasped the first-hand materials and established the foundation for the plan of network design . The third part of this thesis put forward the following suggestions and trains of thought to the construction of the access network, and also put forward the plan of design of the IP network at authentication and billing system, which are based on DHCP+WEB technology. The constructed system can perform such functions as: ●carry on the subscriber's authentication and record the content which the subscriber has visited ; ● customize the cooperative modes of different ICPs freely, customize the function distribution; ● settle the policy of the expenses and discount according to different situations; ● deal with various kinds of complicated account functions ; With the fast development of Henan Province's economic and the roaring growth of the broad-band subscribers' quantity , the subscribers of county towns need more and more broad-band services , which demands that IP network extends to the county towns. For this reason , this thesis put forward some plans of design to extend IP broad-band access network to the county regions.As a project thesis, the fourth part also provides the standard of the broad-band access network designs.
