Platform Virtualization in Set-top Box for QoS Management in Multi-Provider Environment

IMS is a recent initiative, designed by 3GPP and TISPAN partnership, which outlines a service delivery platform (SDP) framework. A flexible and robust QoS management system for IMS is essential to encertain the achievability of service quality on these converged networks. For end-to-end QoS in IMS, our STB is designed to support virtual platforms such that a service provider is able to manage its own multimedia streams using feedback mechanism and ensure the desired QoS. The STB also works as a Home Gateway and provide QoS support to client nodes.
