【摘要】：截至目前，基于IP的传输依旧是最成熟、最可靠的技术，路由和交换是数据传输最为基础的部分，而高效稳定的路由协议是保障可信路由器性能的重要因素。随着信息技术的快速发展和网络规模的不断扩大，路由器需要处理的数据包越来越多，这无疑对路由器的性能带来很大的影响。为了满足人们对路由器性能的要求，现代网络技术对ISIS路由协议进行了诸多扩充。 本文在深入理解ISIS协议及相关技术文档的基础之上，以RFC5120[1]为标准，采用敏捷开发方法，设计和实现ISIS支持多拓扑路由功能。本文的主要工作包括：对系统进行需求分析和建模，在现有ISIS协议实现的基础之上，进行总体设计和模块划分，实现将IPv4和IPv6分拓扑计算来解决路由黑洞问题；将全局拓扑人为的划分为多个不同子拓扑，各个子拓扑分别进行路由计算，，实现在IPv4单播网络中，不同的业务流在相应拓扑内转发功能。最后，在H3C路由器上进行基本功能验证和性能测试。 基于H3C路由器的测试结果表明，ISIS支持多拓扑路由功能正确，系统运行稳定，达到了项目预定的设计目标。
[Abstract]:Up to now, the transmission based on IP is still the most mature and reliable technology. Routing and switching are the most basic part of data transmission, and efficient and stable routing protocol is an important factor to ensure the performance of trusted routers. With the rapid development of information technology and the continuous expansion of network size, more and more packets need to be processed by routers, which undoubtedly has a great impact on the performance of routers. In order to meet the requirements of router performance, modern network technology extends ISIS routing protocol. On the basis of deep understanding of ISIS protocol and related technical documents, using RFC5120 [1] as the standard and adopting agile development method, this paper designs and implements the function of ISIS supporting multi-topology routing. The main work of this paper includes: the requirement analysis and modeling of the system, the overall design and module partition based on the existing ISIS protocol, and the realization of dividing the IPv4 and IPv6 topology to solve the problem of routing black hole; The global topology is artificially divided into several different sub-topologies, and each sub-topology is routed separately to realize the forwarding function of different traffic flows within the corresponding topology in IPv4 unicast networks. Finally, the basic function verification and performance test are carried out on the H3C router. The test results based on H3C router show that ISIS supports multi-topology routing correctly, and the system runs stably, and achieves the design goal of the project.
