Quality of Service for Multimedia Delivery over IP Networks

Abstract

Internet is migrating from a single data network to an environment where a more demanding multimedia content like audio, video, and IP telephony is being delivered. The Internet Protocol (IP) was originally designed to interconnect heterogeneous networks. Multimedia applications require something better than a simple best effort delivery. Many solutions have been proposed to implement quality of service (QoS) on IP networks. Typically, these methods do not take into account the inherent characteristics of multimedia data, and leave most of the network to the end hosts. To provide an appropriate level of service quality, the current best-effort Internet must be supplemented with the ability to distinguish traffic from different service classes and provide different levels of service for these classes. The differentiated services (DiffServ, or DS) framework of the Internet Engineering Task Force (IETF) intends to provide appropriate grades of service to applications having different requirements by using relatively simple yet scalable methods. The deployment of such service-differentiating networks, combined with the end-system application's clever use of service features, will greatly benefit multimedia applications. The major benefit of this research is to evaluate the delivery of continuous multimedia over network of SUST (Sudan University for Science and Technology) and implement the QoS on the SUST network. Therefore, we present analysis to the experiments. Finally, derived the ability to send continuous multimedia (CM) over SUST network.
