Abstract
A system and method for controlling data flow in an available bit rate asynchronous transfer mode ATM network. In the ATM network, a transmitting end station transmits data to a receiving end station across the network. The transmitting end station sends forward resource management (RM) cells across the network, while the receiving end station sends solicited or unsolicited backward RM cells across the network. The receiving end station contains a control module that generates and transmits an unsolicited RM cell having a desired low data flow rate to transmitting end station upon detecting congestion at the receiving end station. The control module also generates and transmits an unsolicited RM cell having a desired high data flow rate to the transmitting end station upon detecting absence of congestion at the receiving end station.
