A cell and burst level control framework for integrated video and image traffic

The authors review the results of a two-level control framework for integrated video and image traffic in an ATM multiplexer. The framework gives priority to video traffic, and uses flow control on the image traffic in order to prevent congestion while improving its throughput. It functions on two levels, or time scales. Buffer management and scheduling are done at the level of cell arrivals and departures, or microsecond time scales, while flow control is done at the burst level, or millisecond time scales. The control framework guarantees upper bounds on cell loss rates for both video and image traffic over a defined control interval, with a specified probability
