Patent ID: 8345548

Claim:
A method for counteracting a saturation tree occurring in a network having nodes, comprising: providing a first list indicating data streams causing a congestion; providing a second list indicating data streams suspected of causing the congestion; generating at a local node where the congestion emerges a first congestion information comprising a first identifier identifying a congested channel; sending the first congestion information to at least one upstream node; responsive to receiving the first congestion information at the at least one upstream node: comparing content of the received first congestion information with a present local status based on a set of rules in order to identify at least one packet stream causing the congestion; storing the first identifier in one of: the first list, and the second list, wherein selecting the first or the second list depends on results of the comparison; generating a second congestion information comprising a second identifier identifying the at least one packet stream causing the congestion; and sending the second congestion information to at least one node further upstream from where the identified at least one packet stream was received: wherein the at least one node further upstream holds back the at least one packet stream identified in the second list.
