Abstract

The method enables the control of congestion in sporadic exchanges of packets of data in a digital transmission network. Each packet is formed by a header enabling it to be identified and to be guided through virtual channels and by a part containing information elements to be conveyed. The method includes detecting, at each node of the network, channels that are congested, and, on nodes upline with respect to each congested virtual channel detected, transmitting a congestion indicator to stop connections on the congested virtual channels so long as the congestion observed by a node on the congested virtual channels has not been cleared.
