PROJECT TITLE :

A Formal Model of QoS-Aware Web Service Orchestration Engine

ABSTRACT:

QoS-aware applications will satisfy not only the useful needs of the shoppers, but conjointly the QoS necessities. QoS-aware Net service orchestration translates the QoS necessities of the shoppers into those of its part Net services. In an exceedingly system viewpoint, we have a tendency to discuss issues on QoS-aware Net service orchestration and design a typical QoS-aware Net service orchestration engine called QoS-WSOE. A lot of importantly, we establish a proper model of QoS-WSOE primarily based on actor systems theory. Within the formal model, we tend to use a three-layered pyramidal structure to capture the requirements of the customers with a concept named QoS-aware WSO service, characteristics of QoS-WSOE with an idea named QoS-aware WSO system, and structures and behaviors of QoS-WSOE with an idea named QoS-aware WSO behavior. Conclusions showing that a system with QoS-aware WSO behavior could be a QoS-aware WSO system and additional can provide QoS-aware WSO Service are drawn.
