Research on the simulation modeling method of service-based network architecture

The research on next generation network has been carried out around the world in allusion to the problem that the Internet fails to satisfy some of high level requirements. As an important branch of the research, the study of network architecture modeling makes many achievements. However, as a major experiment platform of network architecture, the research findings of network simulation are quite lacking. Based on recent research progresses in related fields, we put forward a simulation modeling of service-based network architecture (SNA) and implement the simulation system, SNASA. Through conducting a serious of experiments respectively on SNASA and NS-2 and analyzing their results, the simulation modeling method is considered to be feasible and better than the method of NS-2 for the simulation of SNA with characteristics of scalability, customizability, manageability, etc.
