PIM-SNOOPING协议的分析与测试 摘要 组播技术早已自成为一个系统，组播协议分为组播路由协议和组播组管理协议，其中组播路由协议包含基本的PIM协议、类似IGMP和MLD的组播成员管理协议，还有跨域的MSDP和MBGP协议，在局域网内部的二层组播协议IGMP-SNOOPING等等。 近年来新出了一种组播协议——PIM SNOOPING，它是对IGMP-SNOOPING的补充和改进，更加利于减少带宽占用率，增强网络的健壮性。本论文详细探讨了PIM-SNOOPING的协议分析和测试。文章首先介绍了组播在局域网领域的应用，而后引申出PIM-SNOOPING，其中包括它的工作原理和配置指导。而后探讨了软件测试的流程并引申出协议测试的特点，最后重点诠释了作者在PIM-SNOOPING协议的测试过程中所做的工作。 在测试过程中，主要有对配置，功能，性能等方面进行测试，使用公司系统内的和自己通过对协议的学习设计的测试用例，在测试的同时，加深了对协议的理解，也保证了协议在实际设备上的实用性。 关键词：组播协议，PIM-SNOOPING，协议测试 Abstract Multicast technology has long since become a system, multicast protocols and multicast routing protocols into the multicast group management protocol, multicast routing protocols that include basic PIM protocol, similar to the IGMP and MLD multicast members of the management agreement, as well as inter- domain MSDP and MBGP protocol, in the internal LAN Layer 2 multicast protocol IGMP-SNOOPING and so on. In recent years, out of a new multicast protocol - PIM SNOOPING, it is the IGMP-SNOOPING supplement and improved, more beneficial to reduce bandwidth utilization, enhance network robustness. This paper discusses the PIM-SNOOPING detailed protocol analysis and testing. The article first describes the application of multicast in the LAN area, and then come out of PIM-SNOOPING, including its working principle and configuration instructions. Then explore the software testing process and derive the characteristics of the test protocol, the final interpretation of the authors focus on PIM-SNOOPING protocol testing process work. During the test, mainly on the configuration, features, performance and other aspects of testing, the use of the company within the system and their own learning through the design of the protocol test cases, test at the same time, deepen the understanding of the agreement, but also to ensure agreement on the usefulness of the actual device. Key Words：Multicast protocol, PIM SNOOPING, Protocol test 目录 摘要 i Abstract ii 图目录 III 表目录 IV 第1章 绪论 1 1.1 课题背景 1 1.2 组播体系结构
