集成资源预留与QoS监控框架的元调度体系结构

Metascheduling architecture integrating with framework of reservation and QoS monitoring of resource

缺乏服务质量保证已成为制约网格应用的瓶颈,针对该问题提出一个能够在网格中基于SLA协商资源预留并监控资源的QoS的服务框架。首先定义资源预留的XML Schema,使得资源请求者和提供者基于WS-Agreement能够协商包含关于资源预留的协定;然后遵循WSRF及WS-*规范设计和开发出一组Web服务用于构建基于WS-Agreement的资源预留与QoS监控框架(RMF),并集成到GridWay元调度体系结构中使其能够支持基于QoS协商的资源管理;最后通过模拟实验,客观评估了RMF的性能。

For the shortage of QoS guarantee has become the one of bottlenecks restricting the application of grid,a serviceoriented SLA-based framework which can negotiate resource reservation and monitor the QoS of the resource is advanced. Firstly,the XML schema of resource reservation which can make resource requestor negotiate the agreement about resource reservation with resource provider based on WS-Agreement is defined.Secondly,a set of WS-＊ and WSRF-compliant Web services which are used to construct a framework of reservation and QoS monitoring of the resource based on WS-Agreement （RMF） is designed and developed.And integrating the framework into the architecture of GridWay makes GridWay support the resource management based on QoS negotiation.At last,the performance of RMF is evaluated by the experiment logically.
