Design and Implementation of Cache Mechanism in GridDaen Data Grid

Access to widely distributed massive data in data grid which is a typical distributed system spends a lot of times. This paper introduces cache technique to implement fast data uniform access in GridDaen data grid. GridDaen uses two-level cache, which adopts two cache-data tables to locate cache-data and control data access, designs replacing data algorithm in its cache, and provides a set of flexible config methods which can separate cache from client or server and implement scalable cache in client or server.
