一种自治域边界路由器功能仿真的方法和装置bgn

Method and device BGN for simulating functions of autonomous domain border router

Abstract

The invention provides a method and a device BGN for simulating the functions of an autonomous domain border router. In the invention, the BGN establishes a BGP interconnection relationship with the BGN in a corresponding autonomous domain according to the inter-domain interconnection relationship of a local autonomous domain, the inter-domain routing policy of the local autonomous domain is copied on a platform to realize the overall simulation of the inter-domain interconnection and routing policy of the autonomous domain of the BGN; and meanwhile, the BGN also acquires the performance parameters of the inter-domain interconnecting links of the local autonomous domain through various mechanisms periodically and inserts the performance parameters as well as the related network information of the local autonomous domain into a virtual traffic data packet forwarded by the router so as to complete the simulation and estimation of the inter-domain interconnection routing policy regulation effect of a real internet together with a virtual traffic generation/capture server (VTGCS) which is another important component of a BGP-Grid.
本发明提供了一种自治域边界路由器功能仿真的方法和装置BGN,通过依照本自治域域间互连关系与相应自治域内的BGN也建立BGP互连关系,并在该平台上复制本自治域的域间路由策略,实现对其所在自治域的域间互连和路由策略的全面模拟,同时,BGN还通过各种机制定时采集本自治域域间互连线路的性能参数,并将其连同本自治域的相关网络信息插入所路由转发的虚拟流量数据包之中,与BGP-Grid的另一个主要组件,虚拟流量生成/截获服务器(VTGCS),共同完成对真实互联网的域间互连路由策略调整效果的仿真和评估。
