Abstract
As the next generation networks promise network convergence with services for both static and mobile networks, the research focus is converging towards standardizing a common infrastructure for all-IP networks. IP Multimedia Subsystem (IMS) is a recent initiative, which outlines a service delivery platform (SDP) framework. A flexible and robust QoS management system for IMS is essential to ascertain the achievability of service quality on these converged networks. As Triple and Quadruple Play services are the most celebrated services of IMS in the near future, the necessity of QoS assurance is becoming an imminent need of the hour. Multimedia services delivery in converged IP networks using IMS, concentrates on ensuring capabilities to ensure the best QoS. To meet these requirements, we have designed a set-top box which provides feedback in IMS management architecture to ensure end-toend QoS as well as enables the functionalities of Regional Gateway for the Home Network. Results of the simulation confirm the improvement of performance parameters and the quality of service.
