一种网格环境的服务查找算法

网格计算为大规模Internet应用提供了必要的基础架构,服务查找是网格计算的重要研究内容之一。但是目前常见的服务查找算法不太适应于网格环境的分散性和松耦合等特点。提出了一种分布式的、综合考虑网络延迟和节点负载情况及处理能力、适合于网格环境的服务查找算法DDCA。实验结果表明,DDCA算法能有效提高网格环境下应用的整体性能。

Service discovery algorithm for grid environment

Grid computing provided the basic infrastructure for large scale Internet applications.Service discovery was one of the most important research issues of grid computing.However,traditional service discovery algorithms were not suitable for grid environment due to the facts of inherited decentralization and loose coupling of grid application itself.To address this problem,the limitation was analyzed of those traditional algorithms,and presented a novel grid oriented service discovery algorithm,namely DDCA,which was essentially decentralized.DDCA also took network latency and processing capability into account.Our later experiment justified DDCA's effectiveness in the grid environment.
