In this paper a mechanism for the control of the Available Bit Rate traffic at the access of ATM networks is presented. It is based on the integration of the backpressure and a credit based mechanism. A credit distribution policy among sources, aiming at equalizing the occupancy of the transmission buffers of the sources, is defined. Moreover, the introduction of an uncontrolled mode of operation when the network status is far from congestion allows the signaling overhead to be limited as in

A performance study of the proposed mechanism is presented. Various traffic scenarios are considered. Results arising from simulation are compared with performance of the backpressure mechanism. Moreover, analytical bounds for the cell loss probability are found and compared with the performance derived from simulation.
