Smooth Transition Of Routing Protocol For IP Metropolitan Area Network

Currently, the global telecommunications industry is entering a period of largeintegration, major changes and major transition. At the same time, the arriving of China’striple-play has brought opportunities as well as an enormous challenge for China’s Telecomindustry. As the main part of Telecom’s broadband,IP MAN is also facing major changes.And building a stable, smooth and efficient IP MAN, has become an urgent problem theTelecom industry. As the core issue of IP MAN construction, selecting the appropriaterouting protocols, conducting a reasonable route plan according to the actual circumstancesof the network will directly affect the entire IP MAN’s reliability, stability and efficiency.Therefore, Jinzhou Telecom needs to make reforms to router of IP MAN routing protocolsaccording to China Telecom IP backbone network and metropolitan policy specification.In the premise of a full analysis of IP MAN status, including network architecture,routing protocol routing equipment and based on the comparing with the various routingprotocols, To Jinzhou Telecom to improve object, the present thesis design a program toachieve smooth transition of IP MAN routing protocols. Namely, achieve smooth transitionfrom OSPF routing protocol to ISIS+BGP protocol.Instruction of this thesis:One: Introduce the background, purpose and meaning of smooth transition of IP MANrouting protocols background, purpose and meaning. At the same time, this thesis introducethe relevant scientific fields, and its domestic and international situation and the problems atthis stage.Two: Describe MAN’s OSPF and ISIS routing protocols which belongs to IGP andBGP routing protocol. Firstly, overview their concepts and analyze their feature as well astheir works.Third: the thesis design the program of Jinzhou telecom IP MAN routing remediation,including networking principle and networking standard, as well as the organizationalstructure and routing renovation ideas.Four: Implement the program of Jinzhou telecom IP MAN routing remediation,including specific steps, staff arrangements for the program, the system configuration of theenvironment, the implementation of risk and risk response measures. Five: Summarize this thesis, and propose the next step program to improve.The smooth transition of routing protocol will enable Jinzhou Telecom IP MANnetwork structure greatly optimized and will enhance the satisfaction of the user to real-timeapplication services (such as IPTV, online games, soft switch).At the same time,it canprovide a strong technical support for IP MAN expanding network upgrading, and willenhance Jinzhou Telecom IP MAN more stable, more fast, and more satisfied.
