Performance evaluation of the OLVP (online video processing) system

The paper discusses how the OLVP system, an innovative video-on-demand system, can be used to efficiently support video delivery applications over an asynchronous transfer mode (ATM) network. We show how the OLVP system provided a high quality of service (QoS) to video applications executing over a set of distributed and heterogeneous system resources. System architecture is described. Key functionality, including distributed video storage management, real-time admission control strategy and resource allocation routing mechanism, traffic management and routing algorithms (both in the ATM network and in the OLVP system) are investigated. To illustrate the success of our approach, we provide a performance evaluation based on simulations of the system.
