The Next Generation Network (NGN) architecture, which bases on the IP Multimedia Subsystem (IMS) concept, is a proposition of a telecommunication network dedicated to the needs of the modern information society. The main goal of NGN is to provide Quality of Service (QoS), for which proper network design and dimensioning are necessary. This also requires appropriate traffic models, which should be efficient and not excessively complicated for practical applications. Such a traffic model of a multidomain IMS-based NGN architecture is proposed in this paper. Using the model mean Call Set-up Delay (CSD) and mean Call Disengagement Delay (CDD), a subset of call processing performance parameters defined by International Telecommunication Union Telecommunication Standardization Sector (ITU-T), are investigated for resource reservation with one and two stages. Moreover, network parameters most influential on NGN call processing performance are indicated.
