网格QoS研究

Grid computing is one of most important methods to supply network service through the cooperation of heterogeneous resources distributed in heterogeneous networks, and grid QoS is one of the key factor, that determines success of grid computing coming into practicality and commercialization. This paper addresses the metrics for grid QoS, the decomposing and aggregating rule of QoS parameters, the methods of grid QoS measurement. It also analyzed QoS-based grid computing architecture and model, resource discovery and scheduling methods, and discuss the existing problems in grid QoS research and the research trends of grid computing.
