Modeling and analysis for high-availability softswitch-based clustered media server
Xiaomin Zhu · Journal of Communications · 2006
Based on the system architecture of the softswitch-based clustered media server,a high availability system solution was proposed.Generalized stochastic Petri net theory was employed to model the solution and a lot of simu-lations had been conducted on the model.Results of simulation experiments show that the high availability system solution can improve the availability greatly and thus it is valid.The influences on the availability made by the system repair rate,the number of the request processors and the fault character of the request processor had been analyzed on the basis of the model.The analysis conclusion is important to the availability design of the softswitch-based clustered media server.
