End-to-end system reliability and availability of different IMS-based network communication scenarios have been simulated and analyzed by using the combination of effective stochastic processes and models. Besides, both system reliability and availability characteristics of Intra and Inter IP multimedia subsystem (IMS) domain communication networks have been simulated and compared with different redundancy conditions. Moreover, parallel redundancies of the core IMS units were optimized at different availability or reliability standard conditions. The results demonstrate interesting system reliability characteristics of different communication scenarios and the results reveal possibility to create high reliability and availability system for the Next Generation Networks.
