This paper describes a framework for packet-switched net works that balances the needs of real-time and data applica tions. Routers use virtual queues to mark packets, thereby reflecting a measure of congestion. The network uses these marks to control the admission of time-sensitive traffic and to regulate other traffic. We present a theoretical analysis of this framework. We evaluate the performance characteris tics of this approach in terms of overall link utilization and quality of service of the time-sensitive traffic. We conclude with a discussion of simulation results and of an implemen tation on a test network.
