Providing QoS for Real-time Applications
Teresa Tung, Jean C. Walrand · 2004
This paper describes a framework for packetswitched networks that balances the needs of real-time and data applications. Routers use virtual queues to mark packets reflecting a measure of congestion. These marks are then used 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 characteristics 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 implementation on a test network.
