A novel queuing model for IMS-based IPTV system

IPTV is considered as one of the killer applications in the future. Many standardization organizations such as ITU-T and ETSI are working on standardizing the Next Generation IPTV system. Basically, two different approaches have been defined for Next Generation IPTV system, namely IMS-based solution which reuses the IMS core components as its service controller, and non-IMS approach which has its own service control subsystem known as black box. This paper follows the IMS-based approach and presents a testbed including the basic components of the IMS-based IPTV, which can be used to simulate the real communication environment and test the performances of the IMS-based IPTV system. The IMS registration delay and IPTV call setup time obtained from the testbed are provided, and a novel queuing model for basic IMS-based IPTV system which is verified by the results of our testbed is shown in this paper.
