ATM congestion control algorithm that enables a source to discover the bit rate available between it and a destination in a network. The source transmits a resource manager cell containing the desired bit rate; each switch this cell passes through adjusts the bit rate down to what it can support. Upon reaching the destination, the cell contains the available bit rate and is returned to the source.

"Short for available bit rate, or Class C quality of service, an ATM bandwidth-allocation service that adjusts the amount of bandwidth based on the amount of traffic in the network. ABR service provides a guaranteed minimum bandwidth capacity but allows data to be bursted at higher capacities when the network is free. "
