| 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%。

| 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 router-level 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. Fo... |
