Trader's Quality of Service Specifications and Effects on System Performance for Video-on-Demand

In this paper we present a detailed review on the Trader’s Quality of Service (QoS) Specifications and the Effects on System Performance for Video-on-Demand Multimedia (MM) Applications, based on server-fault initiated session switch. Enhanced Trader lists the resources necessary to support the application’s QoS requirements and makes them available for the Session Manager, which co-ordinates the session switching. Our work demonstrates that all the components of distributed MM system should be involved in the QoS management process. The client’s requirements related to QoS must be adapted to various constraints supported by the distributed MM system components: client machines, server machines and transport system. Our studies in contrast to the existing ones present a comprehensive review on the System Performance with relation to the session switching delay. Index Terms – Quality of Service (QoS), Common Request Broker Architecture (CORBA), Trading Service, Session Mobility (SM) and Multimedia (MM).
