Abstract
The invention describes a method for traffic management in a packet network using random early marking. For each packet flow, packets are randomly marked at the ingress of the network, while discard of the packets at the egress of the network is performed deterministically, i.e. in accordance with the predetermined rules. The step of random marking includes measuring parameters of the data flow, calculating marking probability by applying a mathematical function to the measured parameters, and generating a mark by applying a random logic function to the calculated marking probability. The packets are dropped at the egress of the network if the corresponding queues where the packets have to be stored are congested or full. A corresponding system for traffic management in packet networks is also provided.
