In this paper we verify the previously proposed analytical traffic model of a multidomain Next Generation Network (NGN), which is standardized for delivering multimedia services based on the IP Multimedia Subsystem (IMS). For this reason a proper simulation model used, in which not theoretical queuing system models but the operation of real network elements and standardized call scenarios are accurately implemented. Consequently, the simulation model reflects the phenomena taking place in real IMS/NGN network and can be considered as a reference for evaluation of quality of the analytical results. The output variables assessed using both models are mean Call Set-up Delay (CSD) and mean Call Disengagement Delay (CDD), a subset standardized call processing performance parameters. The investigations are performed for various types of calls and sets of network parameters. As a result, conclusions regarding conformity of the analytical and simulation results in a multidomain IMS/NGN are presented.
