Quality of service estimation research based on the AGWL grid workflow model
基于AGWL网格工作流模型的服务质量估算研究

With regard to the lack of research for QoS composition in ASKALON grid workflow management system, this paper presented a QoS estimation algorithm for grid workflow based on Abstract Grid Workflow Language (AGWL) grid workflow model. Three main features of the algorithm are: 1) Based on AGWL; 2) Scalable QoS metrics model; 3) Multi-dimensional global QoS metrics. Lastly, the feasibility of the algorithm is validated through simulation experiment.
