网格与P2P计算混合模型研究

Research of a Hybrid Model for the Integration of Grid and P2P

网格和P2P(PeertoPeer)都是分布式计算模型,它们的总体目标相似。利用P2P与网格技术之间的协同和互补,构造了一个二层的网格和P2P计算混合模型,上层是网格层,下层是P2P层。P2P层负责消息路由和资源发现,网格层负责为用户提供网格服务。该模型可以解决网格的单点失效、资源搜索等问题,同时增强网格的可扩展性。

Grid and P2P are distributed computing models,they have the similar purposes.We study the issues of combining the two technologies in order to take their advantages while overcoming the problems encountered in each field. We built a two-layer model for the integration of the Grid and P2P networks, which consists of a Grid layer and an underlying P2P layer.P2P layer for underlying message routing or resource discovering and use Grid as upper layer middleware providing services.This model can solve the single point of failure problem, increase the resource discovery efficiency and the extensibility is enhanced in the Grid system.
