The Performance Analysis of Web Service Composition Based on Timed Colored Petri Net

摘要

On the premise of meeting functional requirements, the performance of web service composition is key to customers. Therefore, performance modeling of web service composition has been an important research direction of reengineering. Time coloured Petri net (TCPN) can not only establish a simulation model for system behaviour, but also extract or collect many performance analysis results from the model combined with predefined data monitors, which can satisfy user demands for the performance of QOS, and solve the problems which stochastic process algebra and queue network suffer when analyzing system performance.
