A process used to measure
the actual traffic flow across a given connection and compare it to the total
admissible traffic flow for that connection. Traffic outside of the agreed upon
flow can be tagged where the cell loss priority (CLP) bit is set to 1, and can
be discarded en route if congestion develops. Traffic policing is used in ATM,
Frame Relay, and other types of networks. Also know as admission control,
permit processing, rate enforcement, and UPC (usage parameter
control). See also tagged traffic.
