Paper Abstract

Video communication is one of the most resource demanding services any network has to support due to its high bandwidth requirement, bursty and real time nature. This paper investigates a new multiplexing scheme that improves the network efficiency by reducing the burstiness or variability of the combined MPEG video streams. 6 MPEG sources were individually processed and packetized then the packets joined a common queue and were served by an ATM server controlled by leaky bucket. The simulations were run based on both real MPEG 1 video sequences and sequences modeled by the TES technique. The TES model adopted was a composite of a number of individual processes in order to capture the characteristics of a MPEG video source. The advantages and limitations of the network efficiency significantly while maintaining the acceptable quality of service. The proposed TES model developed is a versatile method to simulate random video sources with various characteristics. The result can be used as a basis for the design and management of VOD like applications.
