Abstract :
In service-oriented architecture, functionally equivalent Web services with different quality can be selected to put together to accomplish a task dynamically. Web service should be chosen by requestors based on their requirements. SLA can satisfy the requirement of requester seamlessly, and QoS-aware Web service composition based on SLA can implement the automation of Web service management, thus it will become one of the directions of future Web service dynamical composition. In this paper, the QoS-aware Web service composition is proposed. The relationship between SLA vector space and QoS of Web service composition is build by functional analysis.
