Abstract

The caching technology is now commonly used to reduce the response time and save the bandwidth for hot Web accesses. The performance can be further improved by clustering several caches together, where a dispatcher is adopted to select a suitable cache from the cache cluster for each request. Therefore, ways to appropriately configure the cache cluster and design the dispatching scheme become important issues. The architecture of distributed dispatchers using the active networking technology is proposed to adaptively dispatch each request to an appropriate cache, according to network conditions and cache loads. The concept of virtual clusters, that distant caches can belong to the same cluster and a cache can belong to more than one cluster, is also proposed to balance the loads of caches globally.
移动网络中Web缓存的主动调度方案
缓存技术现在通常用于减少响应时间和节省热Web访问的带宽。通过将几个缓存聚在一起,可以进一步提高性能,其中采用调度程序从缓存集群中为每个请求选择合适的缓存。因此,如何合理配置缓存集群和设计调度方案就成为重要的问题。提出了采用主动网络技术的分布式调度程序体系结构,根据网络条件和缓存负载自适应地将每个请求分配到合适的缓存中。为了实现全局缓存负载均衡,还提出了虚拟集群的概念,即远程缓存可以属于同一个集群,一个缓存可以属于多个集群。
