Abstract
According to the present invention, traffic control in an IP based network is provided. For this purpose, traffic situation in the network is measured, and the traffic flow is controlled on the basis of the measured traffic situation. Moreover, an operator may define rules for different measured situations, and the traffic flow is controlled on the basis of these rules.
