Grid resource discovery model based on the hierarchical architecture and P2P overlay network

Abstract

The Grid technology enables large-scale sharing and coordinated use of networked resources. The kernel of computational Grid is resource sharing and cooperating in wide area. In order to obtain better resource sharing and cooperating, discovering resource must be efficient. In this paper, we propose a Grid resource discovery model that utilizes the flat and fully decentralized P2P overlay networks and hierarchical architecture to yield good scalability and route performance. Our model adapts efficiently when individual node joins, leaves or fails. Both the theoretical analysis and the experimental results show that our model is efficient, robust and easy to implement. © IFIP International Federation for Information Processing 2004.
