ACR: Allowed Cell Rate

Allowed Cell Rate (ACR) is an ABR service parameter, defined by the ATM Forum for ATM traffic management. ACR is the current rate (cells/second) at which a source is allowed to be sent. ACR varies between the MCR (minimum cell rate) and the PCR (Peak Cell Rate ), and is dynamically controlled using congestion control mechanisms.
