As network-centric computing becomes more pervasive and applications become more distributed, the demand for flexible and efficient message delivery is increasing. Messaging middleware is a key technique of message delivery between distributed computing applications. The main communication models of current messaging middleware are publish/subscribe and point-to-point. The two communication models have their own characteristics. However, neither of them can achieve efficiency and flexibility simultaneously. In this paper, we proposed and implemented a hybrid communication model based messaging middleware (HCM3), which takes full advantages of two models. Performance result shows that HCM3 can deliver message in heterogeneous environment with the features of high efficiency, flexibility and reliability.
