基于内容分发的Cache集群系统

文章设计和实现了大规模基于内容请求分发的系统。一个VS／DR或VS／TUN调度器作为系统的单一入口点，将请求分发给一组KTCPVS分发器，KTCPVS分发器通过使用中心的内容位置服务来确定处理该请求的后端服务器，然后，再将该请求分发到后端服务器，并提出基于局部性的最小负载调度算法。最后将该体系结构应用到大规模Cache集群系统中加以验证。

Cache cluster of content-based request distribution

We design and implement a large-scale content-based request distribution system. VS/DR or VS/TUN load balancer acts as a single entry point of the system, and distributes the incoming requests to a number of KTCPVS distributors. KTCPVS distributor queries the central Content Location Service to decide the right backend server to process the request, and then forwards the request to that server. We give a locality-based least loaded scheduling algorithm. Furthermore, we apply this architecture to build a large-scale Web cache cluster to test and check.
