Abstract
A method and system for controlling congestion in an ATM network comprises the steps of pre-allocating, for a pre-determined interval of time, a set of burst access parameters to a set of pre-allocated virtual paths between a set of source node and destination node pairs in the ATM network, and controlling, at the burst level, the traffic at each source node based on the pre-allocated set of burst access parameters and without communicating with other nodes in the ATM network. Specifically, the network, for a pre-determined interval of time, pre-allocates a set of virtual paths between each source-destination node pair in the network, pre-allocates a set of maximum permitted rates to the pre-allocated set of virtual paths, respectively, and pre-assigns a set of burst access thresholds to a set of service classes, respectively, in the pre-allocated virtual paths, where the pre-assigned burst access thresholds are less than or equal to the corresponding pre-allocated maximum permitted rates. Based on the maximum permitted rates and the burst access thresholds, each source node in the network then controls, at the burst level, the traffic directed to the source node without communicat…
