摘要： “中国高速互联研究试验网”是我国第一个全网支持非隧道组播协议的下一代高速互联网试验床。NSFCNET文章根据组播网络的基本原理,结合的具体特点,对组播网络的结构进行了设计。全网采用NSFCNETNSFCNETPIM-和路由协议,选取清华大学路由器作为全网的汇聚点。域与域之间通过协议交换SMMBGPRPNSFCNETCERNETMSDP本域的活动源信息。文章还详细介绍了组播网络调试步骤和使用的工具。该文对于其他非隧道组播网络的设NSFCNET计、配置和调试具有参考价值。

Abstract: National natural science foundation of China network (NSFCNET) is the first high-speed computer network test bed providing native multicast service across its backbone .This paper presents the design and debugging of NSFCNET multicast network. NSFCNET adopts PIM-SM,MBGP and MSDP for its multicast routing. A set of troubleshooting tool is used to help to test and debug the network after configuration. The paper can provide useful information for the design, configuration and debugging of other native multicast networks.
