摘要
如何提高网络的利用率,加快信息的传递速度是网格技术需要研究的重要内容。以OGSA作为体系结构的网格系统中主要采用关系模型作为其信息模型,采用通知机制作为其信息传递机制。在分析OGSA体系结构的基础上,对信息传递机制进行了研究,提出一种适应于网格环境的信息传递机制——推-拉模式信息传递机制,该机制能够较好地弥补通知机制的不足。
How to improve network utilization, and how to speed up information transmission are important aspects of grid technology. The grid system which takes OGSA as its architecture uses relational model as its information model, a notification mechanism as its information transmission mechanism. Based on the analysis of OGSA architecture, researches on the information transmission mechanism and proposed an information transmission mechanism, push-pull mode transmission mechanism, which can be adapted to the grid environment. This mechanism is proposed to be able to better compensate for the lack of notification mechanism.
