Trader´s quality of service specifications and effects on system performance for video-on-demand

We present a detailed review on the Trader´s quality of service specifications and the effects on system performance for video-on-demand multimedia applications, based on a 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 a distributed multimedia 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 multimedia system components: client machines, server machines and transport system. Our studies in contrast to existing ones present a comprehensive view on the system performance with relation to the session switching delay
