A method and system for controlling congestion in an IP network (160) 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 se t of source node (100a) and destination node (100c) pairs in the IP network (160) and controlling at the burst level. Specifically, a network controller (120) for a predetermined interval of time, determines a set of routes betwe en each source-destination node pair in the network, preallocates a set of maximum permitted rates to the predetermined set of routes, respectively, an d pre-assigns a set of burst access thresholds to a set of service classes, respectively, in the predetermined routes, where the pre-assigned burst acce ss 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 (100a) in the network (160) then controls, at t he burst level, the traffic accessing the network and reserves for each admitte d burst the burst peak packet rate on a predetermined route, without communicating with other nodes in the network.
