Claim Text:
1. A method for congestion control in a network node of a communication network, said network node being adapted to handle a plurality of data connections for conveying data between a first side and a second side of said communication network, wherein the congestion control involves associating the data connections with respective target weights for Quality-of-Service (QoS) bit-rate differentiation, the method comprising the steps, in said network node, of: obtaining experienced bit-rates for the data connections; for each data connection: using the adjusted weights for the congestion control of the data connections; wherein calculating the adjusted weight for an individual data connection involves calculating a scaling factor v where p>0 is a settable parameter which determines a tradeoff between an ability to adapt to environmental changes in said communication network on the one hand, and reduced adaptation accuracy of small continuous variations on the other hand, where r k (t) is the experienced bit rate, and where w i (t) is the target for the individual data connection.
