Abstract
A packet congestion control technique employs an Active Flow Random Early Drop (AFRED) method to provide a service requiring a predetermined bandwidth with a stable Quality of Service (QoS) even when network congestion occurs. The packet congestion control technique includes: receiving at least one packet flow; defining identifiers for the received at least one packet flow; numbering each of the defined at least one packet flow; calculating a queue length of each of the at least one packet flow; allocating a maximum queue threshold value, a minimum queue threshold value, and a maximum probability value of each of the at least one packet flow; and dropping or accepting an incoming packet of a flow according to the calculated packet drop probability upon a queue length of a currently received packet being between the maximum queue threshold value and the minimum queue threshold value.
