Research of Grid Resource Discovery Model
Proposed a new model of grid resource discovery based on WSRF.The model uses three-layer structure as its architecture,and the resources are organized in the method of both centralized and decentralized way.Main functions of gird resource discovery are packed into the stateful web services.Presentd resource membership protocol and resource search algorithm for the model.The advantages of both web service and peer-to-peer architecture are all absorbed into this model.This paper also analyzes the efficiency of the model and proves that it is suitable for large and heterogeneous grid environments.
