Performance analysis of voice and video services in isochronous LANs and systems

The performance of voice and video services is evaluated for isochronous LANs or systems that have time division multiplexing (TDM) channels with fixed bandwidth for real-time traffic. The isochronous bandwidth resources are shared by voice and video traffic which have different bandwidth requirements. The blocking probabilities for voice and video arrivals are obtained analytically for the case where channels are allocated randomly without using a policy. Two policies for bandwidth allocation of voice and video traffics under various traffic load conditions are evaluated. The simulation results show that substantial improvements can be achieved if efficient allocation policies are used.
