摘要
从Internet的结构特征入手,分析了BGP的收敛特性与域间路由系统的幂律特性与层次性之间的关系。根据域间路由系统的幂律特性以及AS间商业关系的层次性特点建立了三层幂律—层次模型,剖析了不同层次上的不同收敛事件的收敛参数与网络结构本质的联系。在此基础上,提出了"Best Up"的收敛模式,取得了显著效果。
The relation of BGP convergence and the characteristics of the inter-domain system was analyzed. The inter-domain routing system is classified into three hierarchies-core layer, transmit layer and stub layer based on the power law and commercial relations of autonomous systems. The relation of network topology and convergence parameters were presented of all sorts of convergence events in different layers. And a new proposal has been presented to improve BGP convergence based on the above analysis, called Best Up, which behaved better than normal convergence mode in the experiments.
