ABSTRACT:
The invention relates to a method for controlling overload in a packet switched network, especially in a network where Transmission Control Protocol (TCP) is used as the transport layer protocol. In order to inform the traffic source at a very early stage that the network is getting overloaded or congested, duplicate acknowledgments are transmitted towards the traffic source when the measured load level exceeds a predetermined threshold.
