ATM Traffic Descriptors
Purpose of Traffic Descriptors
When you create a PVC, you can select one of several traffic descriptors by
entering the desired value in the Conformance Type field on the user inter-
face windows for certain connection types. The traffic descriptor 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 high-priority cells are tagged as low-priority cells when traffic
exceeds the traffic parameter thresholds.
