TrafficDescriptor

Use TrafficDescriptor to manage the templates that describe traffic characteristics of a VC (virtual circuit) that are used in the creation of PVCs (permanent virtual circuits. A traffic descriptor is a list of parameters that specify the characteristics of a PVC ATM connection. Each descriptor is defined from a specific combination of parameters.
