Henan Unicom's IP Backbone/Man Optimization And Expansion Program Design

With the extensive development of INTERENT applications and the rapid increase of business needs, broadband metropolitan area networks construction and development has entered a new stage.Nowdays a single network service, such as voice, data and multimedia services, has been achieved in the IP network.But due to the weakness of IP networks, such as service quality, secuirity, etc.,can not provide a guaranteed carrier-grade service. That is to say, the current INTERNET can not provide carrier-class service yet. IP network technology have got great development for this reason, such as MPLS technologies, QoS, network security, and multicast technology, etc., on the one hand to solve the network's business diversity, but also eager to resolve the QoS and other telecommunications level business needs problems.This paper focus on Henan Unicom for IP backbone/MAN design optimization of capacity expansion plan and study how to make MAN MAN in maintaining the original goal of transforming the functions and objectives and target performance of the same structure based on the continuous upgrading broadband access, continue to promote the flat layer network, improve network reliability. This paper first analyzes the current situation of IP MAN, including network structure, various types of resource use, the deployment of network protocols in terms of the various deficiencies of the existing network to sum up, then on this basis the overall optimization of capacity expansion plan to develop the technical design, focus on the various types of business planning and implementation program, the new policy setting QOS and multicast, IP Integrated Network Management, cutover and implementation of various business programs, in order to achieve the target of perfecting thefunction and making reasonable structure and excellent performance target network.
