摘　　要：对现有的常用的两种网络拓扑测量技术进行了分析研究,实现了基于traceroute技术的网络拓扑测量系统并用其测量了中国网络,通过与Iplane的测量结果对比评价了其可用性。首先讨论了基于SNMP协议的拓扑测量方法,并指出其优缺点。随后讨论了基于traceroute技术的拓扑测量方法,描述了基于traceroute技术的拓扑测量系统的设计构架和关键技术。最终利用拓扑测量系统测量了中国网络拓扑,然后将其测量结果同Iplane测量的中国网络拓扑进行复杂网络特征分析。通过特征对比发现,测量系统挖掘出的拓扑呈现出更显著的非相称性、更弱的聚集和更短的距离,证明了该系统的可用性。In this paper, the existing two common network topology measurement techniques are analyzed, and it imple- ments the network topology measurement system based on the technology of traceroute. After that the paper uses it to meas- ure the Chinese network, furthermore evaluates its usability by contrast with the result of Iplane. This paper first discusses the topology measurement methods based on the SNMP protocol and points out its advantages and disadvantages. Then it discusses the topology measurement method based on traceroute technology and describes the architecture and key technolo- gies of the topology measurement system based on traceroute technology. Finally, the paper uses the topology measurement system to measure the network topology of China, and analyzes the complex network characteristics of the measurement resuits of Iplane and the topology measurement system. It is found by feature comparison that the topology extracted by the topology measurement system shows significantly more non - proportionality, weaker aggregates and shorter distance.
