动态网格环境下资源发现的研究

Research for Resource Discovery in a Dynamic Grid Environment

网格中资源是动态变化的,资源状态的不断改变,使得资源发现变得更为复杂。文中提出了一种适合于三层P2P结构的资源发现的算法,它利用复制技术缩短查找的时间,节省内存开销,并给出了消息传播过程中所使用的一些协议,解决了传播过程中存在的问题,更好的适应了网格资源的动态变化。

Resources in Grid environment are varied from time to time, and this results in resource discovery to become complicated. In this paper a piece of new resource discovery arithmetic which fits three-layer peer-to-peer structure is proposed and it uses copy technology to reduce the time of query. It can also save memory＇s spending. Some criterions are suggested in the course of spreading. And it solves the problem existing in the spreading, so it can suit better in a dynamic Grid environment.
