摘要
网格技术为地理上广泛分布的资源的共享和协作提供了很大的便利,信息服务是其重要组成部分,而信息服务的性能属性直接影响整个网格平台的服务质量.本文设计了一种基于网络属性的新的信息服务机制,该机制将IP属性与网络的带宽和链路的传输延迟时间相联系,将每一用户任务调度至最合理的资源上执行,使任务向资源的总提交时间最短,从而优化了资源的分配调度过程,提高了网格性能.
Grid technologies provide much convenience for sharing and collaboration of distributed resources,and the information service is the most important component of grid which can influence to the QoS of the grid platform.In this paper,a new grid information service mechanism based on network attributes is designed which considers the relationship of IP attribute,bandwidth of network and transmission delay of link.The scheduler can dispatch each task to the most proper resource.
