Abstract: The relationship between cache servers and backup cache servers is dynamically managed, and when a fault has arisen, a second cache server that is close in terms of distance to a PBR router that is forwarding traffic to a first cache server at which the fault has arisen is used as a backup cache server. Also, a module or a device having functionality as a cache manager and a cache agent is prepared, and with the trigger being the detection of a fault in the first cache server, the cache agent automatically alters the traffic forwarding destination of the PBR router, which is forwarding traffic to the first cache server at which the fault has arisen, to be the second cache server that is close in terms of distance to the PBR router.

Abstract translation: 高速缓存服务器与备份缓存服务器之间的关系是动态管理的，当发生故障时，第二个缓存服务器与距离PBR路由器的距离相近，该路由器正在将流量转发到发生故障的第一个缓存服务器 用作备份缓存服务器。 此外，准备具有作为高速缓存管理器和高速缓存代理的功能的模块或装置，并且通过触发器检测第一高速缓存服务器中的故障，高速缓存代理自动更改PBR路由器的流量转发目的地， 这是将流量转发到出现故障的第一缓存服务器，作为距离PBR路由器的距离很近的第二高速缓存服务器。
