摘要

摘要: R.Al-Ali提出了一个基于网格的服务质量(QoS)管理框架模型,该模型将网格QoS问题划分为应用层QoS、网格中间层QoS以及网络层QoS,并重点对应用层的QoS表示和优化等问题进行了研究.目前关于网格QoS方面的大多数研究都集在对应用层如何扩充WSDL文档以实现服务等级协商(SLA)的表示等问题上.对于如何将应用层所需要的QoS与网络传输层的QoS机制模型结合起来以适合于网格计算的研究还是相当少,为此提出了一种基于策略的网格QoS管理模型,该模型既能够屏蔽由于网格应用服务使用不同的QoS级别带来的映射差别,也能够屏蔽由于跨越不同组织所采用不同QoS机制模型带来的映射差别.当组织的QoS机制模型采用差分模型(DiffServ)时,对所提出的模型进行了初步仿真,仿真结果表明可以将这一策略模型集成到开放网格服务体系(OGSA)中实现对网格应用服务的QoS管理.

Abstract: A quality of service(QoS) management model for grid is proposed by R.Al-Ali, the issues for grid QoS are divided into QoS of application layer, QoS of grid middleware and QoS of network layer. Research focus on expression for application layer service level agreement(SLA) by extending WSDL and optimization issues etc.. The research is a little for regarding application quality of service and network layer service of quality as whole. Therefor, a kind of QoS management model for grid based on policy is proposed. The motive is to shield differences for mapping application services’ QoS into transport services’ QoS from all kinds of QoS mechanism model employed by all organizations or different QoS level employed by application services for grid. When organization employs differentiated services(DiffServ), the QoS management model for grid is simulated, primarily. The simulated results show this QoS policy management model for grid can be integrated into OGSA to implement QoS management for grid application service.
