The Transformation And Optimization Fromal And Implementation Of China Tietong Hegang Branch IP Metropolitan Area Network

Metropolitan area network operator in the city within the building IP backbone network, mainly carrying a variety of Internet-based business, the city is an important information infrastructure. In recent years,"electronic commerce" and "enterprise VPN network," and "intelligent communities", such as Internet-based new business start one after another. Heguang TIETONG original IP Metropolitan Area Network has been unable to meet the dynamic growth of the business requirements of its shortcomings and inadequacies of the network has become increasingly clear that the reform must be optimized.This article first Jiamusi TIETONG IP Metropolitan Area Network Rail to carry out an analysis of the status quo, put forward the need to tranform and optimize. And Core layer routing algorithm, QoS jitter algorithms, security keys for in-depth research. According to the Heguang TIETONG and then the actual demand, combined with the results of the study, Heguang TIETONG IP network from the design principles of network architecture, technology selection, and other aspects of the design, studied at the same time QoS and network IP MAN Security for the deployment of IP MAN network optimization, and full use of the existing network resources on the basis of Heguang on the original IP Metropolitan Area Network Rail to carry out the implementation and network design of transformation and optimization,than realizing.Finally, after optimization of Heguang TIETONG IP Metropolitan Area Network performance was evaluated with test results show that the optimized IP Metropolitan Area Network Rail Heguang is a carrier, management, to offer differentiated QoS capability to protect the multi-service Bearer network. To meet the future for a long time Heguang opening more branches of business development.
