%X In order to solve the problems of conventional resource discovery framework, a hierarchy-based model was discussed, which combined super-peer model and contact node, a membership join protocol was introduced, and a resource discovery algorithm was proposed based on Time To Live (TTL) limit and cache list. The network framework with good scalability can adapt to complexity and heterogeneity of grid resources. The simulation shows that the algorithm works well, query time is minimized and efficiency of resource discovery is improved in grid environment.
