ATM Traffic Descriptors
This appendix describes how each traffic descriptor (TD) combination affects the cell
streams under different traffic conditions. When you create either a PVC or a
point-to-multipoint (PMP) circuit, you select one of several TD combinations. The
traffic descriptor combination specifies which traffic parameters are used for traffic
control. It also determines the number and type of cells that are admitted into a
congested queue, and whether or not high-priority cells are tagged as low-priority
cells when traffic exceeds the traffic parameter thresholds.
