Traffic descriptor profiles capture the cell arrival pattern for resource allocation. Source traffic descriptors for an ATM connection include at least one of the following:
Sustained Information Rate (SIR)
Peak Information Rate (PIR)
Minimum Information Rate (MIR)
Maximum Burst Size (MBS)
QoS traffic descriptor profiles are applied on IES, VPRN, VPLS, and VLL SAPs.
ATM traffic descriptor profiles are not supported on the 7950 XRS.
