摘　　要：提出了一种改进的基于简单网络管理协议(SNMP)的网络拓扑发现算法。该算法以标准MIB-Ⅱ信息为基础,并依据TCP/IP协议编址相关原理,实现网络拓扑的快速发现,并进一步降低了网络的负载。基于第二代中国教育和科研计算机网CERNET2进行了实验。实验结果表明该算法可以快速准确地发现网络拓扑结构。An improved SNMP-Based network topology discovery algorithm was put forward. This algorithm could, based on MIB- Ⅱ and TCP/IP protocol addressing principles, accelerate the speed of topology discovery and reduce the network loads. This system was developed at CERNET2. The results of experiments were presented on a map. The results show that this system can discover the network topology quiekly and exactly.
