Abstract

本发明实施例公开了一种实现跨域路由分离的方法。在源节点发起至宿节点的基于同一呼叫的跨域分离路由连接请求时，源节点向网络拓扑信息所在节点请求路由计算，获得每个域的入口子网点池、出口子网点池及域间路由信息。每个域的路由计算服务器根据入口子网点池、出口子网点池及本次连接的呼叫标识与连接标识，计算出本次呼叫下所有连接的域内分离路由集合。由于域间路由计算可以保证域间路由分离，而本地路由计算服务器计算可以保证域内路由分离，因此，利用本发明实施例可以实现跨域分离路由连接的建立，同时在本次呼叫中任何一条连接需要重路由、优化等路由动态改变的情况下，可以继续保证路由的分离，从而提高了业务的生存性。
