<p>In an ATM network, a source end system is connected through multiple virtual channels to destination end systems to exchange resource management (RM) cells at periodic intervals and transmit data cells at allowed cell rates (ACRs) respectively set for the virtual channels. The source end system transmits a forward RM cell through an associated virtual channel, and determines a sum of ACR values of the virtual channels in response to receipt of a backward RM cell through the associated virtual channel and compares the sum of ACR values with a predetermined capacity of the access link. The source end system resets a current ACR value of the associated virtual channel equal to a lower-than-previous value when the sum of ACR values is in excess of the predetermined link capacity. In one embodiment, the sum of ACR values is divided by the predetermined link capacity to produce a link load value and the ACR value is reset according to the link load value.</p> |
