The invention relates to a method for traffic control in a communication system transferring traffic units. The invention includes maintaining a continuously changing quantity determining whether an individual traffic unit can be forwarded, changing the value of the quantity so that a traffic density lower than a specific predetermined value changes the value of the quantity in a first direction, but no more than up to a predetermined first limit, and a traffic density higher than said predetermined value changes the value in a second direction. Further, the inventing relates to rejecting traffic units as the value of the quantity in said second direction reaches a specific predetermined second limit. In order to save the network bandwidth, the value of the quantity is also changed for the rejected traffic units in the second direction, but no more than up to a specific predetermined third limit, and when the value of the quantity is between the second and the third limit, it must again alter in said first direction up to at least the second limit before traffic units are accepted. |
