OPNET环境下的PIM-SM组播路由协议仿真

摘要

IPv6组播技术作为下一代互联网的核心技术之一,相对于IPv4组播技术具有更大的优越性.文章首先对PIM-SM组播协议在IPv6上实现PIM-SM涉及的问题进行了论述,然后在OPNET网络仿真模型中实现了对IPv6和IPv4混合网络场景的配置,进行组播的仿真实验比较单播与组播网络的性能,系统地分析了PIM-SM协议在OPNET中的实现.%As one of the core technologies in NGI, IPv6 multicast technology has more advantages than IPv4 multicast. At first, this paper presents the problems on implementing PIM-SM for IPv6. In OPNET network simulation model, it deploys a mixed IPv6 and IPv4 network scenario. Then, a simulated experiment has been done to compare the network performance of unicast with that of multicast, and analyses systematically the realization of PIM SM in OPNET.
