Analysis Method of Dynamic Extensible Service Model Based On Petri-Net

摘要

It is a big challenge to realize the dynamic change of the network environment and user's demands. A dynamic application customization and extensible service composition model is proposed in this paper. In order to guarantee the rationality of the service composition, the composition model of on-demand service that based on Petri net is proposed. Then the model is analyzed to validate whether the service composition can achieve the desired target. Finally, the result shows that the model can guarantee the correctness of extensible service, validate the rationality and effectiveness of the method.
