An HSM-based scalable network service model

The scalability of the ability to provide and deploy network services is one of the major demands of the next generation network, and is also the main challenge of the development of the network service model technique. Through the comparison of several different network service models and the analysis of the key mechanisms of the next generation network, this paper proposes an HSM (hierarchical state machine) based scalable network service model which can dynamically build the users' required network services. The paper gives an example of implementing a network transfer service with connections using our proposed dynamic service composition method. The experiment results illustrate the feasibility and flexibility of this scalable network service model.
