摘要
AS-域内路由器双层建模方式是目前构建Internet规模的路由器级网络模型的最优方案,而该方案需要建模者首先了解域间路由器级连接的特点。指出AS类型对域间路由器级连接具有较大影响,通过定义域间参数映射,利用现网数据对域间参数映射进行了现象学分析,获取了不同类型AS相关参数的分布函数,解决了双层模型的组合问题。在此基础上,进一步对Internet建模尚需解决的若干问题进行了讨论。
Currently, the AS-router double layer modeling is the optimal scheme for constructing Internet-scale router- level topology model, while it needs researchers to understand the characteristics of the Inter-AS router-level network topology. This paper pointed out that the type of AS has a great influence on Inter-AS router-level connection. After de- fining the mappings of Inter-AS parameters, we analysed the phenomenolog on CAIDA network data and obtained the distribution function of different Inter-AS parameters. And then we solved the problem of the combination of AS-level topology and Inter-AS router-level topology. At last, more problems of the Internet modeling that need to be solved were discussed.
