摘要： 高性能网格应用需要端到端QoS保证,GARA是Globus建议的网格QoS体系结构,但目前不支持MPLS。MPLS支持面向连接的QoS,为更好地提供网格QoS,该文提出了用MPLS扩展的GARA体系结构,并为此进行了试验,结果表明扩展的GARA能够很好地为网格应用提供QoS保证。

Abstract: High-end grid applications have demanding end-to-end quality of service (QoS) requirements. GARA is a grid QoS architecture proposed by Globus. But MPLS, which supports connective QoS, is not supported by it now. An extended GARA by applying MPLS is proposed . Results obtained from simulations demonstrate the ability of this improved architecture to deliver QoS for grid application.
