摘要
首先分析了当前Grid和P2P相结合的体系结构研究。然后基于面向服务的概念提出一种以资源信息和任务信息的汇聚为核心的网格体系结构。将资源与任务抽象为信息,使资源分配和任务调度转换成基于信息汇聚协议(Infor-mation Aggregated Protocol,IAP)的信息匹配操作。在信息节点间使用P2P交互方式,基于信息有机融合P2P和Grid。与应用混合式P2P路由协议的系统比较,表明应用IAP协议的系统具有较小处理消耗和较小网络带宽损耗。
The paper analyzes the current researches about the architecture combining the grid and P2P.Then,a grid architecture based on the service oriented which is focused on the information aggregated of the resource and task information is presented.The resources and tasks are abstracted to information.So,the resource allocating and task scheduling are regarded as information matching operation based on the Information Aggregated Protocol.The information peers use the P2P scheme to exchange,and the P2P and grid are combined based on the information.Experiments show that the bandwidth cost and process cost of the system with information aggregated protocol are less than with the hybrid P2P routing protocol.
