Abstract
This paper addresses the problem of modelling call processing performance (CPP) in a multidomain Next Generation Network (NGN) architecture including the elements of the IP Multimedia Subsystem (IMS) in service stratum and based on the Multiprotocol Label Switching (MPLS) technology in transport stratum. An analytical traffic model for such an architecture is proposed by integrating the formerly implemented submodels of service stratum and MPLS-based transport stratum. The integrated analytical model allows investigation of mean Call Set-up Delay (E(CSD)) and mean Call Disengagement Delay (E(CDD)) for a large set of input variables corresponding to both IMS/NGN strata. The evaluation of E(CSD) and E(CDD), which are a subset of CPP parameters, is very important for both network users and operators. Details regarding the structure and operation of the integrated traffic model are provided in this paper. Moreover, the results of investigations are described, which demonstrate that this model is correctly implemented, reflects the operation of a multidomain IMS/NGN network and may be used in further research.
