Abstract
The present invention relates to a method and network element for scheduling data transmission in a packet data network, e.g. a differentiated services network. Data traffic of a predetermined traffic class is classified based on a predetermined traffic profile, e.g. responsive or non-responsive traffic, and an in-profile rate of the data traffic is estimated. Then, a weight determining a transmit order of queued data packets of said predetermined traffic class is adjusted according to the estimated in-profile rate. Thus, the data traffic is marked into different classes based on the traffic profile and a queue scheduler improves fairness between the classified flows in the packet data network. Thereby, enhanced fairness between traffic profiles can be achieved easily and effectively.
