Abstract
A method and system for controlling congestion in an IP network comprises the steps of preallocating, for a predetermined interval of time, a set of burst access parameters to a set of predetermined routes between a set of source node and destination node pairs in the IP network, and controlling, at the burst level, the traffic at each source node based on the preallocated set of burst access parameters and without communicating with other nodes in the IP network. Specifically, a network controller, for a predetermined interval of time, determines a set of routes between each source-destination node pair in the network, preallocates a set of maximum permitted rates to the predetermined set of routes, respectively, and pre-assigns a set of burst access thresholds to a set of service classes, respectively, in the predetermined routes, where the pre-assigned burst access thresholds are less than or equal to the corresponding preallocated 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 accessing the network and reserves for each admitted burst the burst peak pac…
