一种机群网络文件系统的合作高速缓存技术

随着网络技术和工作站性能的发展，合作高速缓存成为进一步提高机群的系统上的网络文件系统性能的有效方法。本文提出了适于机群系统的基于分布式客户／服务器模型的合作高速缓存结构，设计了一种采用改进的ＬＲＵ替换策略的弧本优先一致性协议，并对该协议的模拟实现的测试结果进行了分析评价，说明全作高速缓存的使用可大大减少磁盘访问次数，有效降低文件访问的平均响应时间。

COOPERATIVE CACHING IN THE NETWORK FILESYSTEM ON WORKSTATION CLUSTER

With the development of network technology and workstation performance, cooperative caching becomes an effective way to improve the performance ofnetwork filesystem on workstation cluster. This paper presents a cooperative cachestructure based on distributed client/server model and a single copy preference consistency protocol for the structure. By analyzing the result of simulation system,this paper demonstrates that using cooperative cache can greatly decrease the frequency of disk access and effectively reduce the response time.
