【摘要】：本文以沈阳铁通城域网的扩容改造为背景,研究IP宽带城域网的优化改造与应用问题。随着广大用户对高品质宽带的日益需求以及上网用户数的高速增长,沈阳铁通原有的IP宽带城域网已不能满足宽带业务的发展需求,需要在原有网络框架的基础上,改造成一个安全可靠、性能优越、层次清晰,具有强大流量转发能力、扩展能力及可运营的IP网络,能够为广大用户提供更多的宽带业务应用和高品质的宽带接入。针对未来宽带业务的发展需求,本文首先对对网络流量优化和物理结构的改造进行规划和设计。通过对沈阳铁通IP宽带城域网的物理结构改造进行分析,规划结构框架,使网络层次清晰化、网络结构扁平化。探讨如何在整个宽带城域网内部署动态路由协议,根据接入层、汇聚层、核心层的网络需求和对OSPF、BGP等路由协议进行分析比较,选择最优路由协议。对于互联网高成本的网间结算,研究并制定出宽带城域网流量、流向的优化方案,并针对铁通宽带城域网的实际情况进行部署和调整。针对铁通IP宽带城域网的维护,探讨了其中需要解决的问题,对网络的结构以及日后宽带业务的需求进行了详细的分析,提出了可靠的网络结构的设计方案。对网络中的软件、硬件的实现技术进行了总结。对改造后的网络进行了较为全面的测试,结果表明该设计方案是满足实际应用需求的。
[Abstract]:This paper studies the optimization and application of IP broadband metropolitan area network based on the capacity expansion of Shenyang Tietong MAN . With the increasing demand of high - quality broadband and the high - speed growth of the number of users on the Internet , the existing IP broadband metropolitan area network in Shenyang can not meet the development requirement of broadband service .

In order to meet the development demands of broadband business in the future , this paper firstly plans and designs the improvement of network traffic optimization and physical structure . By analyzing and comparing the physical structure of Shenyang Tietong IP broadband metropolitan area network , this paper discusses how to deploy dynamic routing protocol in the whole wide band metropolitan area network . The optimal routing protocol is selected according to the network requirements of the access layer , aggregation layer , core layer and the routing protocols such as OSPF and BGP .

Aiming at the maintenance of IP broadband metropolitan area network , this paper discusses the problems to be solved , analyzes the structure of the network and the demand of broadband service in the future , and puts forward a reliable network structure design scheme . The software and hardware realization technology in the network is summarized . The results show that the design scheme is satisfied with the practical application requirements .
