【摘要】 近年来,随着电子商务,高速数据传送,点播电视,会议电视等业务在企业中的应用和发展,这种主要面向集团用户和普通用户的公用网网络应运而生,它能够支持多种网络通信协议,同时能为用户提供安全可靠,丰富全面的多种业务,并且它可以覆盖数百公里,这就是宽带城域网。宽带城域网在现有网络架构中,经过网络的优化与扩容的调整,已经逐步改造成为一个有着扎实稳定的结构、安全高质量的运行环境、并且具有功能强大而且稳定的处理和兼容能力的网络,能够使用户方便快捷的享受高速的宽带网络以及更多样化的网络综合业务的应用,这将会是目前营口铁通网络在电信运营商中发展前进的重要因素。该论文对营口铁通宽带城域网进行了现网分析、现网结构中存在的问题进行分析,并且对未来宽带业务发展方向的规划,以及对营口铁通宽带城域网网络结构的规划、改造和实施,并且通过SIG系统对用户流量优化控制。该文章首先对营口铁通宽带城域网现网网络结构进行分析,通过对网络拓扑图详细准确的规划,网络结构深入细致研究,使其结构规范化、标准化、层次化。其次分析不同种类的路由协议,例如EGP、BGP等协议,研究动态路由的部署以及不同路由协议在城域网网络结构层次中的部署情况。再者对营口铁通城域网流量的优化,通过SIG系统对流量的控制,使网络用户上网质量得到提高,并且减少铁通流量流出产生的运营成本。最后针对营口铁通城域网当前面临的情况展开有效的调整和优化。通过在营口铁通的这几年积累的大量的城域网维护和建设经验,同时查阅许多关于营口铁通的维护和建设资料,对营口铁通城域网这些年的发展历程、组网方式、网络现状有了比较全面的了解,使得对网络改造方案有了更深刻的研究与掌握,全面规划铁通城域网在改造过程中要解决的各种问题,设计出安全可靠、稳定的网络设计方案,对营口铁通今后的发展方向进行了全面细致的研究。对网络改造中用到的技术方法,例如路由协议、软件硬件等给出测试结果,最后对改造后的网络进行总体测试并给出测试依据、前期准备、中间过程和最终的测试结果。更多还原

【Abstract】 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.更多还原
