Abstract
AbstractAs deployed Grids increase from tens to thousands of nodes, Peer-to-Peer (P2P) techniques and protocols can be used to implement scalable services and applications. The super-peer model is a novel approach that helps the convergence of P2P models and Grid environments and can be used to deploy a P2P information service in Grids. A super-peer serves a single Virtual Organization (VO) in a Grid, and manages metadata associated to the resources provided by the nodes of that VO. Super-peers connect to each other to form a peer network at a higher level. This paper examines how the super-peer model can be used to handle membership management and resource discovery services in a multi-organizational Grid. A simulation analysis evaluates the performance of a resource discovery protocol; simulation results can be used to tune protocol parameters in order to increase search efficiency.KeywordsDiscovery ServiceGrid EnvironmentDistribute Hash TableAverage Response TimeGrid ServiceThese keywords were added by machine and not by the authors.
