【摘要】 通过结合SNMP[1]与ICMP[2]的相关特性,提出了一种基于DNMAI[3](分布式网络测量和分析基础架构)的可定制的网络拓扑发现方法,并给出了拓扑信息的采集、过滤算法与数据库结构的定义。最后,详细描述了网络拓扑图形的程序实现过程,并在网络测试平台上得到了实际测试结果。更多还原

【Abstract】 Refer to the SNMP and ICMP,presentd a new method of automatic Internet topology discoved under DNMAI(Distributed Network Measurement and Analysis Infrastructure),which offers a dynamic configuration interface to users.Then,it described the algorithm of how to collect and filtrate topology data and introduced the definition of the database structure.Finally,it discussed the program implementation procedure of Internet topology graphics in detail and got the testing result by using a network test platform.更多还原
