| In recent years,with the diversification and intelligence of Internet business,as well as the vigorous development of cloud computing,big data and 5g emerging business,new requirements have been put forward for the existing telecom operator network.Therefore,it is very important to optimize the provincial Internet as a hub network for telecom operators.Referring to the evolution trend of provincial Internet at home and abroad,combined with the analysis and Research on the backward Internet architecture,single function and limited capacity of Tietong provincial Internet,this paper concludes that it is difficult to change the overall network problems only through partial optimization,only for the access capacity,routing organization,traffic model,export scheduling,cache deployment,traffic control,content introduction,network management and control of the network And other aspects of the overall optimization can be solved.Through the research and verification of technical problems,a scientific optimization scheme is formed,which mainly uses BGP and Isis protocol to solve the problem of imperfect routing organization;adopts the differential flow direction guidance model of backbone and provincial export to solve the single problem of flow model;solves the problem of low export quality and cost controllability with the help of dynamic and static export scheduling model,and applies cache technology HTTP cache is deployed near the exit,which greatly relieves the pressure of outgoing traffic;DPI flow control at the backbone and the exit of the province solves the problem of weak traffic protocol control capability;CDN and DNS technologies are used to introduce and guide the NDC content in the network to solve the problem of low network traffic rate;SNMP and netstream network management technologies are used to build the support system to solve the network control means Imperfect problems.In addition,the optimized network is improved and strengthened.Through the optimization effect analysis and index verification,the network traffic cost in the province is reduced by about 20%,and the network performance index in the province is improved by about 30%.After the provincial Internet optimization,it greatly improves the scientificity of the provincial network architecture,and gradually turns it into an easy to manage and operate intelligent IP network,which also provides the network foundation for the implementation of China Mobile Group's "big connection" strategy. |
