| Abstract [eng] |
The goal of this work is to determine information traffic that pass through session border controllers, taking into consideration the variety of services. Analyze of research resources on SBC thematic is done on the problematic part. According to it the goal of this work as well as the tasks to reach it is set. Analysis part of this work deals with the new generation (NGN) and IP Multimedia Subsystem (IMS) features. Session border controllers are analyzed, emphasizing their functionality and usage on the network capabilities. Call flows of the network with session border controllers are analyzed. The study part of this work consist packet flows calculations assessing usage of different services. Tele traffic theory models are used in order to conduct qualitative characteristics analysis of the traffic flows. Several different cases are analyzed according to traffic changes, interface or real device efficiency. |
