摘要: 通常利用测量手段获取ISP拓扑,然而如何评估测量数据的完整性尚缺乏深入研究。总结了影响拓扑测量数据完整性的因素,指出存在准确的节点完整性评估方法,但是不存在准确的链路完整性评估方法。提出了一种基于地理信息的骨干链路完整性评估方法。以CAIDA组织提供的skitter数据作为测量样本进行了分析,实验表明对中国电信骨干网Chinanet而言,skitter测量到的骨干链路完整性其近似上限为40%。
关键词: skitter数据, IP网络, ISP拓扑, 完整性评估
Abstract: ISP topology is usually acquired by measurements. However, how to estimate the integrity of the measurement data is still lack of intensive research. The factors influencing the integrity of routerlevel topology were summarized. It was pointed out that there was accurate node integrity estimation method and no accurate link integrity estimation method. A link integrity estimation method based on geological information was proposed. The skitter data provided by CAIDA was analyzed as a measurement sample. For the China Telecom's backbone network Chinanet, the integrity ratio of the backbone links measured by skitter is no more than 40%.
Key words: skitter data, IP network, ISP topology, integrity estimation
