Research On Network Optimization And Flow Control Based For Broadband Metropolitan Area Network

In recent years, e-commerce, high-speed data transmission, video on demand, video conferencing and other services in the enterprise application and development, this mainly for groups of users and regular users of the public network network came into being, it can support a variety of network communication protocols, and can provide users with safe, reliable, comprehensive rich variety of business, and it can cover hundreds of kilometers, which is broadband MAN. Broadband metropolitan area in the existing network architecture, optimized and adjusted expansion of the network, has gradually transformed into a stable structure has a solid, safe and high-quality operating environment, and has a powerful and stable handling and compatibility of network, enabling users to enjoy the convenience of high-speed broadband networks and more diverse applications integrated services network, which will be an important factor in the current Yingkou Railway network development and advancement in telecommunications carriers.The thesis of Yingkou CRC broadband MAN current network analysis, the current network structure to analyze the problems and plan for the future direction of development of broadband services, as well as planning Yingkou Railcom broadband metropolitan area network structure, transformation and implementation and user traffic through the SIG system optimization control. This article first Yingkou CRC broadband metropolitan area network architecture to analyze the current network, the network topology through detailed and accurate planning, network intensive research, its structure standardization, hierarchy. Second, analysis of different types of routing protocols such as EGP, BGP and other protocols, as well as the deployment of dynamic routing study different routing protocols in the metro network structure hierarchy deployment. Further optimization of Yingkou CTT MAN traffic flow control by SIG system that allows network users to the Internet to improve the quality and reduce operating costs generated by the CRC flow out. Finally, the case of Yingkou CTT MAN facing mounting effective adjustment and optimization.In the past few years by the accumulation of a large number of MAN Yingkou Railway maintenance and construction experience, and access to a lot of maintenance and construction information on CTT Yingkou, Yingkou CTT MAN these years of development, networking, network status with a more comprehensive understanding of network transformation program makes a deeper study and mastery of a comprehensive plan for the CRC MAN in the transformation process to solve a variety of problems, design a safe, reliable, stable network design, right Yingkou CTT future direction of development and market demand for a comprehensive and detailed analyzes. Technical methods used in network reconstruction, such as routing protocols, software and hardware, such as test results are given, and finally the transformation of the network and give an overall test test basis, preparation, intermediate process and final test results.
