信息栅格通信服务系统结构及工作原理研究

Research on System Structure and Working Principle of Communication Service in Information Grid

信息栅格解决了现有各种网络资源之间存在的异构性问题。通过提供统一的栅格通信服务,屏蔽底层网络资源的差异,并通过网络管理服务掌握其网络状态,对其进行更加有效的管理和调度,提高网络的利用率。同时,接纳控制服务可以更加高效地对用户需求进行接纳控制,满足用户的QoS要求。文中以当下研究的热点问题栅格技术为切入点,针对信息栅格中的通信服务系统进行了深入研究。详细分析了信息栅格的具体层次结构,阐述了信息栅格中通信服务系统的组成,并研究设想了信息栅格通信服务系统的工作原理。

Abstract：The information grid solves a problem of isomerism between network resources. By providing uniform communication service, the differences in ground networks are shielded. The network resource management service masters the status of networks, in this way, communication network in infon^aatlon grid can manage and schedule them efficiently and the utilization of network resources are im- proved obviously. At the same time, the admission control service can control the admission of user＇ s transmission demand efficiently and increase user＇ s QoS. It does a deep research on the communication system in information grid, analyzing its hierarchy and system compo- sition, and expounding the operation principle of it.
