有状态网格服务结构与复制方法研究

网格服务与静态资源不同，是有状态的，能够随时间和网格用户的调用不断的改变自身状态。为了能够消除州格服务的访问瓶颈、实现对网格服务的就近访问和网格服务的负载均衡，必须能够实现对有状态的网格服务进行复制。而网格服务的复制需要对许多不同的动态改变的资源进行复制，即对网格服务运行所需的硬件环境进行搭建、软件环境进行复潮，本文就有状态网格服务结构与复制方法进行了探讨。

The research on structure of grid service with state and replica creation mechanism

Grid service have state,which is different from the static resource,and can change their state with the time and the call from the grid users.For the sake of avoiding the bottleneck of accessing the grid service to achieve handy access and load balance for the grid service,the replication of grid service with state should be realized.The replication of grid service demands the replication of many resources which changes their state dynamicly,such as the construction of hardware environment,the replication o...
