Calculate The Quality Of Service In The Economic Grid

Grid is a basic infrastructure for user to together hold many different resources. How to make resources owners actively contribute their resources to Grid and for others to use , which is a key problem for Grid to grow bigger. So,a good incentive mechanism that Grid combine with economic appears. It is called economic Grid management technology. In this ecomic environment,the resource provider can earn monmey, and has to offer good quality to Grid user ,which is the important aim in economic Grid studying field. However, in the Grid econocic environment ,the study of QoS is not mature now, and the study method both consider the two aspects of time and cost shuoud study further.This paper does some study and analysis on Grid economy architectures GRACE (Grid Architecture for Computational Economy). According to the existing architectures' characters, this paper propose a new GRACE framework which has two parts .One is a SLA(Service Level Agreement) control module,called SCM and the other is a new compensatation mechanism to improve the aspect of reliability of resources. Then this paper introduces the detaile of SCM and the compensatation mechanism framework ,and introduces the work flow of the new GRACE. At last ,this paper proposes a new resource distribution arithmetic ,which can balance the users' and resource providers' profit, and make the high QoS resource will be use exactly. The arithmetic can improve the percent of both Grid resources'utilization and Grid service's request.Through simulation experiments in GridSim environment, the results show that the improvements of Grid economy architecture and resource distribution strategies would improve the both benefits between users and resource providers.
