Optimizing Design Of Baotou Netcom Broadband IP Metropolitan Area Network

Broadband IP Metropolitan Area Network is the extension of the broadband IP Backbone Network within the range of a city. Its typical technique characteristic is that the breadth of transportation and node are realized within the range of city area.In recent years, the growth of the data customer and surfing the Internet by broadband customer is big in BaoTou Netcom. Both the broadband accessing need of the Key Accounts and the Group customers and the fiber optical accessing need of the intelligent residential area increase sharply. Because the customer need grow fast, the broadband IP Metropolitan Area Network of BaoTou was constructed without overall, careful, relative farsighted planning, therefore, the structure of the network exist unreasonable places. The business model of present network is simplex. There isn't increasement of income with the increasement of business quantity. Network construction has no considerable scale. It is hard to satisfy the various of customers' need of accessing network,quality of service,network safety etc. Therefore, perfecting the network structure, promoting the comprehensive business loading ability of the IP network, setting up efficient and safe IP MAN is a great problem that should be solved urgently by BaoTou Netcom.This design analyzes deeply and detailed the network structure of BaoTou Netcom broadband IP MAN, transportation optical route, network safety and the situation of customer etc. It finds out the existent problems of the network and puts forward an able solution to optimize its structure in engineering design. By increasing outcome bandwidth, adding aggregation nodes, reallocating access nodes, enlarging range of access layer and optimizing transportation route, its capacity, function, ability and reliability are enhanced substantially. It will make the BaoTou Netcom IP MAN become telecommunication class network which can operate, manage and benefit.This paper is total to have 6 chapters. Chapter 1 introduces the basic concept of broadband IP Metropolitan Area Network and network structure, and describes the research background, points out the meaning of network optimizing. Chapter 2 describes the present network structure and business situation of BaoTou Netcom IP MAN. Chapter 3 elaborates thoughts and destination and basic principle of network optimization. Chapter 4 enumerates the base of optimization. Chapter 5 discusses layering optimizing method and its realization means of BaoTou IP MAN.
