为了解决当前Internet拓扑生成器研究领域缺乏系统比较工作的问题,基于对Internet拓扑模型和度量指标的分析,对5个具有代表性的拓扑生成器进行了自治域(AS)级和路由器级的多项性能测试,并建立了拓扑生成器的量化评估系统,以评估各拓扑生成器的性能.结果表明,new Internet topology在AS级中性能最佳,TopGen在路由器级中最接近当前Internet拓扑. In order to solve the problem of lacking of system comparison in the research field of Internet topology generators, based on the analysis of Internet topology model and metrics, five representative topology generators are studied at AS level and router level Item performance test and built a quantitative evaluation system of topology generator to evaluate the performance of each topology generator.The results show that new Internet topology is the best performance in AS level and TopGen is closest to the current Internet topology at the router level.
