Abstract
A communication system comprises a plurality of nodes interconnected by links comprising a plurality of connections. The traffic between the nodes is set up by a reserved bandwidth service and/or a non reserved bandwidth service. The non reserved bandwidth service is controlled by a hop by hop backpressure mechanism. When the traffic entering a node exceeds a high threshold, the backpressure mechanism generates stop backpressure primitives in order to throttle the entering traffic. In case of congestion the mechanism is either able to selectively interuppt the connection contributing to the congestion without affecting the rest of the link traffic, or to globally stop all link traffic. Traffic can be resumed if traffic rates fall below the low threshold values.
