Estimation of ATM Traffic Descriptors for the Transport of MPEG-4 over ATM Using the Virtual Buffer Measurement Technique

"In this paper, we applied the virtual buffer measurement technique to estimate near-minimal sets of ATM traffic descriptors for transport of stored MPEG coded video over ATM networks. To evaluate estimated traffic descriptors (TDs) accuracy, we simulate the transport of the MPEG-4 SPTSs over an ATM network with a traffic policing function in the access point. The results had shown that for a great majority of the MPEG-4 traces, the VB technique is capable to estimate a near-minimal set of ATM TDs. However, an improvement must be done so that it can be used to estimate near-minimal TDs for any MPEG-4 sequence."
