Title :
Priority mechanisms in ATM switches carrying two layer video data
Abstract :
Switching of two-layer coded video signals in an ATM environment is considered. To eliminate the output contention of the switch, cells from both layers are stored either in a separate or a joint buffer. The impact of these buffers on the cell loss rates and the delay variation between the two layers is investigated. An alternative buffering mechanism which enhances the switch performance is given.
