Structural Analysis And Optimization Design Of Integrated IP Bearer Network

IP bearing network using IP packet to carry voice, data and multimedia and so onmany kinds of information,Not only fully inherited existing IP intracity networksprovide ISP service, but also can provide voice, IPTV, Cloud services etc of rich andunique new business, with technology, cost advantages. It is the next generation of thedevelopment trend of bearing network.TCP/IP protocol has advantages of highlyopenness,But the essence of IP network tried to transfer to meet the current applicationof Internet needs. The the network structure of the existing IP network of the operatorsmust be adjusted, the hierarchic QoS and VPN,must be made, so that birth defects ofthe the IP network can be compensated.Aiming at the above questions, with a certaintelecommunication IP network status as a research object, the research, planning anddesign of the IP development of comprehensive carrying nets are made.The first chapter presents the background paper topic knowledge, analysistelecommunications operator choose IP technology build the overall carrying the causeof the nets. The second chapter explaining IP comprehensive bearing network and thehistorical evolution of the basic concepts, analysis the comprehensive carrying netscommonly used IP agreement. The third chapter of a large telecom IP overall carryingnetwork research background, detailed analysis of the design requirements, probes intothe present situation and IP （Internet specific problems, and puts forward thecomprehensive bearing network design process IP of various links face key problem.The fourth chapter proposed expansion of business bandwidth growth link to meetdemand; The network structure transform flat network low latency, and low cost ofmanagement; Routing optimization to realize the transformation of the networkconvergence speed and routing management controlled; QinQ technology to achievebusiness logo; To realize the VPN shunt bearing; multi-protocol label switching（MPLS） To control the quality of the IP QoS business comprehensive bearingnetwork optimization scheme. Chapter5analysis IP overall carrying nets facing themain security threats and puts forward some basic solutions. Chapter6of this papersummarized the work back.
