Abstract:
A method performed by a component of a packet switching system, the method comprising:determining a sending delay, said determining the sending delay including selecting a random number based on a congestion parameter; receiving an indication of allowance to send to a particular destination of the packet switching system; delaying a time duration corresponding to the sending delay before sending packets to the particular destination after receiving the indication; determining the congestion parameter based on a previous duration of non-allowance for sending to the particular destination; comparing the congestion parameter with a predetermined target value; varying a range of values for the time duration based on a result of the comparing the congestion parameter with the predetermined target value; wherein said determining the sending delay comprises selecting the random number within the range of values; wherein said determining the sending delay comprises selecting the random number based on a random value within a smaller range of values if the congestion parameter is greater than the predetermined target value, and within a larger range of values if the congestion parameter is less than the predetermined target value.
