网格中面向服务的资源预留与QoS监控框架

Service-oriented Framework of Resource Reservation and QoS Mointoring in Grid

针对目前尚无遵循OGSA/WSRF规范的网格服务中间件能很好地支持基于QoS协商的网格资源管理,提出一个面向服务基于SLA的框架,协商资源预留并监控资源的QoS。定义资源预留的XML Schema,使得资源请求者和提供者基于WS-Agreement协商包含资源预留的协定。遵循WSRF规范没计和开发出一组Web服务,用于构建基于WS-Agreement的资源预留与QoS监控框架,通过试验评估该框架的性能。

For there is no OGSA or WSRF-compliant grid service middleware presently to support the gird resource management based on QoS negotiation commendably. A service-oriented Service Level Agreement（SLA）-based framework which can negotiate resource reservation and monitor the QoS of the resource is advanced in this paper. The XML Schema of resource reservation which can make resource requestor negotiate the agreement of resource reservation with resource provider based on WS-Agreement is defined. A set of WSRF-compiiant Web services used to construct a Framework of reservation and QoS Mointoring of the resource based on WS-Agreement（RMF） is designed and developed. The performance of RMF is evaluated by the experiment.
