【摘要】 在网格环境下,资源以服务的形式共享。针对虚拟组织内网格服务的动态性和广域性,分析了网格服务的特点,指出了网格服务建模需要着重考虑的因素,并建立了其相应的数学模型,对其进行了初步分析,对若干个小规模虚拟组织组成的网格系统进行了仿真实验,实验结果验证了模型的合理性。更多还原

【Abstract】 In grid, all resources are shared in the form of services. The dynamic characteristic and scalability of grid is introduced and analyzed, especially the important factors in modeling grid service. A related mathematical model is given here with preliminary analyses. The experiment in a small scale grid system with several VO, each consists of some resources as the service providers, validates the model provided in this paper.更多还原
