Service Level Agreement( SLA) is widely used in defining requirements which the quality of a service must fulfill. Build the service quality model based on the SLA. There are two kinds of metrics in the quality model,one is atomic and the other one is composite. According to metrics in the model develop a quality management system to monitor services in a SOA system. This management system consists of four main parts,including monitor,QoS calculator,SLA analyzer and repair scheme. The system has been tested in many different situations. The result shows that the system is competent to monitor QoS and analyze SLA violations. As the system uses a technology independent on monitoring interface so that it can be extended and adopted in different kinds of SOA systems.
