Abstract

The growth of concurrent requests from increasing applications based on web service aggravates the load of web service, and may result in low performance or even breakdown of the invoked web service. However, some requests are similar or related, and can be integrated into a slightly complex one, which can be resolved by the service provider in a unified way. Based on this fact, a requirement group-based web service scheduling model (RGBWSSM) is proposed. It concentrates on the integration of similar or related requests and the capability matching between the integrated request and web services, both based on OWL-S. Moreover, a case study is implemented and the results show that this model is effective and useful in reducing web service load in the environment of high concurrent service requests.
