P2p Collaborative Communication Model And Derivative To The Grid Collaborative Communication Protocols

The essence of Grid computing are distributed character and parallelism。P2P software has distributed character inherently. Add parallelism and enhance its distributed character will promote P2P software's performance and improve its reliability and availability. So we analyze the architecture of P2P computing and the architecture of Grid computing. The point across by the two theories is the distributed character and the cooperative computing.After analyze the two theories's architecture and the cooperative file-exchange model inducted by BitTorrent, we got a new model for cooperative communicate. This model is different from cooperative file-exchange model.Then we describe the problem the cooperative communicate model will induce. And we give some advice to solve the problem.The main idea to solve this problem is to measure and monitor the bandwidth and the load of the network, and then restrict the exploitation of the bandwidth.At the end, we analyize the position that cooperative communicate should be in P2P computing and Grid computing. Then we try to evolve this model to a Grid service protocol.
