The Design And Implementation Of Network Cutover For Provincial Routers

With the rapid development of the Internet industry,the number of Internet users and business types are continues increasing,the users of the existing operators put forward higher demand to the network services.In August 2013,the State Council issued a " Broadband China " strategy implementation plan to respond the national policies and meet users' needs.Modifying and optimizing the existing Internet has become the main task to the internet operators.The main research contents of this thesis come from the network optimization project of China Tietong Communications Corporation in Henan province.Firstly,this thesis introduces the status of the Internet and describes several kinds of network technology which be used,including the dynamic routing protocol such as BGP(Border Gateway Protocol),IS-IS(Intermediate system to intermediate system),and routing policy.Secondly,this thesis briefly analyzes the overall structure of the company's network,and detailed analysis the present situation of the network and shortcomings in Henan province from the aspects of network structure and protocol type.Then this thesis puts forward a new network topology,and selects eNSP(Enterprise Network Simulation Platform)as the simulation software.Then the whole process of the simulation network environment is given.According to the optimization requirements,this thesis designs a scheme which includes network cutover,data traffic grooming.Then several test devices added in the program.Finally,this thesis gives all configuration processes which is involved in the previous chapter.And it implements the feasibility test,connectivity test and stability test about the whole optimization program.The implementation and test results of the simulation program verify the optimization plan is rationality and reliability.Works of this thesis meets the anticipated request,and it will lay the foundation of implementation of the optimization project.
