Abstract: To make up for the lack of router-level topology based on HOT, a complex router-level topology model A2R is designed through a combination of AS-level topology and router-level topology. A2R rely on the number of the routers to complete network topology. A2R complete the inference of business relationships between AS-level topology without BGP and achieve the connections of routers between AS. Experiments show that A2R topology model has better performance than other models in large-scale routers.

摘要： 针对HOT模型的路由器级拓扑在大规模节点下的不足，通过结合自治域级拓扑和路由器级拓扑两种方法，实现了一种复合型Internet路由器级拓扑模型A2R。A2R模型仅依靠路由器规模完成网络拓扑图，解决了自治域拓扑间商业关系推测依靠BGP表的问题，以及自治域间路由连接的问题。实验证明A2R拓扑模型在大规模节点下比其他路由器级拓扑模型拥有更好的性能。
