Method And Devices For Performing Traffic Control In Telecommunication Networks
First Claim
1. A method for performing traffic control in a network, the network comprising at least one link, the method comprisinga) measuring the data traffic rate, said data traffic comprising at least one data flow, at at least one link which carries said data traffic;
- b) defining a first and a second threshold value, said second threshold value being larger than said first threshold value;
c) determining whether the measured data rate is larger than said first threshold value; and
if so, starting congestion signaling of a first type;
d) determining whether the data rate is larger than said second threshold value; and
if so, starting congestion signaling of a second type, wherein at least one of said first and said second threshold values are modified over time, based on data traffic information.

Abstract
A method is disclosed for performing traffic control in a network, the network comprising at least one link, the method comprising: —measuring the data traffic rate, the data traffic comprising at least one data flow, at at least one link which carries the data traffic; —defining a first and a second threshold value, the second threshold value being larger than the first threshold value; —determining whether the measured data rate is larger than the first threshold value; and if so, starting congestion signaling of a first type, —determining whether the data rate is larger than the second threshold value; and if so, starting congestion signaling of a second type, wherein at least one of the first and the second threshold values are modified over time, based on data traffic information.

15. A network element which is adapted for functioning as a node of a network, said network element comprising
a) means for communicating with a management system, to hereby receive initial (first and second) data traffic rate threshold values and optionally a set of constraint rules; -
b) means for measuring the data traffic rate at at least one link; c) means for analyzing the measured traffic rate in view of said (first and second) threshold values and optionally said set of constraint rules; d) means for modifying the first and second threshold values based on said analysis.
