The Strategy and Method of QoS Parameter Processing for Grid Service Matchmaking

Quality of service (QoS) support is a very important work in service-oriented grid system. The current ways to process QoS parameters is inefficient, even lead to a failure very easily. To solve these problems, the, paper researched general QoS parameters, and put forward a new parameter called GSQN (grid service quality number) to depict the profile of qualitive characteristics of a grid service. Afterwards, a strategy of QoS parameters processing and a price model were presented in the paper, which can reduce the complexity of matchmaking process. The simulation was also accomplished, consequently, experimental data indicates a better performance and agrees with the final computation results
