A P2P Based Web Service Grid Resources Management Model

In order to solve effectively single point invalidation, accession bottleneck, expansibility and dynamic characteristic of grid resource management and discovery, A Web service grid resources management two layers model based on P2P technology is proposed. The upper layer of the model is based on the structural P2P networks of distributed hash table. The other layer is the non-structural P2P networks composed of Web service resource nodes and user nodes. The grid resource expansibility and dynamic characteristic is solved It uses WSDL Language to describe the service resources and then describe resources registration, discovery and cancel procedure. At last through the structural analysis and experiment, it shows that the model improves the grid resource search efficiency, scalability, and reliability of system.
