Analysis and simulation of the next generation network with real time communication in high traffic PSTN mode

In this paper will be explained implementation and simulation of the NGN model in the field of PSTN with high traffic load. For the first time, this simulation will be done using OPNET simulation having designed all needed elements in hierarchial manner. OPNET model enables us to simulate the scenarios of creation, establishment and disconnection of calls. This design is conducted in order to simulate the voice communications. Protocols of NGN networks in Real Time communications will be used here; instances include protocol “MEGACO” in the area of information interchange and protocol “RTP” in the area of voice communications, and point-to-point bilateral links for transfer in IP context. Investigating the behavior of the designed network in overload (high traffic) conditions comprises. The results of our simulation can be applied in hardware and software development of NGN network for PSTN Applications in near future.
