摘要： The purpose of the invention is to provide a distributed cache system applicable to a large-scale network having multiple cache servers. In a distributed cache system including multiple cache control servers, the content information is divided and managed by each cache control server. When content requested from a client is stored in the distributed cache system, a cache cooperation router forwards the content request to the cache control server which manages the information of the requested content. A cache control server has a function to notify its own address to the distributed cache system when the cache control server is added to the distributed cache system. When a cache control server receives the notification, it sends content information to the new cache control server and synchronizes the content information. Thus, a cache control server can be added to the system with ease.
摘要翻译：本发明的目的是提供一种适用于具有多个缓存服务器的大规模网络的分布式缓存系统。在包括多个高速缓存控制服务器的分布式缓存系统中，每个高速缓存控制服务器对内容信息进行划分和管理。当从客户端请求的内容被存储在分布式高速缓存系统中时，高速缓存协作路由器将内容请求转发到管理请求的内容的信息的高速缓存控制服务器。当缓存控制服务器被添加到分布式高速缓存系统时，缓存控制服务器具有向分布式缓存系统通知其自己的地址的功能。当缓存控制服务器接收到通知时，将内容信息发送到新的缓存控制服务器并同步内容信息。因此，可以容易地将缓存控制服务器添加到系统。
