MPLS VPN Network Design And Practice Of China Telecom Of Yinchuan

Along with the network popularization development and network data transmission amount of rapid growth, how to realize the end-to-end forwarding control and QOS became a difficult task to people before, now IP routing technology and network mode against network expansion and many value-added services provided, and ATM technical difficulties, routing flexibility low and inefficient face great challenges. These largely promotes the fusion of IP and ATM technology, realizing routing and exchange technology, the fusion of multi-protocol label switching (MPLS) technology also is made.MPLS is the IP technology since the next generation of wan transmission technology, make full use of data tags in open communication network on high-speed, high transmission. MPLS technology in a connectionless networks structure introduces connection modes and thereby reducing the network complexity, and is compatible with all kinds of existing mainstream network technology, can greatly reduce the network QoSts, while MPLS in IP networks, VPN, traffic engineering authored QOS are widespread application.This paper analyzes the present situation and the yinchuan telecommunications network telecommunication users and network according to the needs of the development of the design and construction based on MPLS VPN intracity networks. This network reconstruction in order to guarantee the smooth transition of network, mainly in original network structure based on the backbone equipment upgrades. At the same time through MPLS VPN technology to achieve VPN, ensure that the agency's safety. Realize VPN technology has a lot of kinds, chose MPLS VPN technology, because based on MPLS IP VPN network easily with based on IP network users combine, without having to change Intranet applications, because these network has applied familiarity with the confidentiality of and QoS placed inside a network. To further enhance the yinchuan telecom MPLS VPN network efficiency and optimize the network traffic equilibrium network equipment of flow, enhance the performance of the network, the optimization enable traffic engineering, the purpose is to improve the operation efficiency and reliability of the network, and optimize the network resource utilization and flow performance.The main achievements made in the paper is theoretically further enriched yinchuan telecom IP intracity networks and IP Internet technology development, through the science of optimization scheme accelerate ningxia telecom broadband Internet network construction process, further help enterprises to improve the broadband network quality and improve telecom in the age of the Internet competition ability.
