China University Of Petroleum Netcom Broadband Network Optimization Program

Since 2003, the building of China University of Petroleum Netcom broadband network since the user has exceeded more than 8000 households, but with the development of a variety of network applications and user scale growth, a number of shortcomings of existing networks gradually become apparent, restricted bandwidth application and user development. In order to ensure the smooth development of broadband services in the current situation, through the expansion and optimization of adjustment in the original network, based on the realization of a technologically advanced, controllable and can be pipes, safe and reliable, with strong delivery capabilities and service functions of the IP network, to provide high-speed broadband access, provide more broadband services, the application is the starting point of this topic.Describes the problems and the existing network analysis, network optimization, as well as the overall direction for the more common current international group of network programs. Stone large network with the actual situation and put forward a "backbone network to adjust the network structure, the core layer of the progressive realization of the exchange model to a routing model from the evolution of existing network resources, IP / VLAN ID for rational planning and optimization," network optimization goals, the same time, the premise of the network running smoothly, through the bridge device to force the client to download Pirates of the access way to curb the phenomenon of private access and improve the quality of the whole network operation.BRAS network for the original method using side-hung some of the problems arising from proposed metro core routers, BRAS direct attached solution. At the same time reduce the network-level user access network, broadband access network using a pure two-story structure, PPPOE the end user in the BRAS, the converged network architecture using vertical tree, business access control points to the only path to each client, there is no loop for all routing. After optimization of the whole network routing switching function is performed by BRAS completed, the ability to give full play to the BRAS, but also to enhance the quality of the network operation.Finally, the optimized stone largest broadband campus network to do a system-wide monitoring, comparing the situation before adjustment operation of the network and user's perception, which indicates that the successful realization of this network optimization of an early goal, a success.
