摘要： 随着CAIDA探测方式由Skitter到Ark的改变,基于2008-02-27～2008-02-29的CAIDAArk项目数据及2007-08-16的CAIDA Skitter项目数据,通过建立网络拓扑和仿真分析单测量点数据与整合数据在平均度、聚类系数、核数等多个特征量上的差异,对比了Skitter和Ark项目在单测量点探测上存在的误差,再对两种探测方式下数据的度分布进行对比.研究结果表明,Ark项目单测量点误差稍小,两组数据在度分布上既存在相同的规律也稍有差异.

Abstract: The change of CAIDA detection mode from Skitter to Ark was investigated, based on the data of Ark project over February 27~29, 2008 and that of Skitter project on August 16, 2007. Setting up the network topology and analyzing the difference between the data measured from single vantage points and integrated data in several characteristics values, e.g., the degree of average, clustering coefficient and coreness, the errors of measured data sets from single vantage points in Skitter and Ark projects were compared with each other, as well as the degree distributions of their measured data. The results revealed that the errors of the measured data from single vantage points in Ark project are slightly smaller, and that the two data sets in both projects are basically the same with few discrepancies.
