Abstract: A method of controlling congestion of network equipment that connects networks with each other, includes determining a type of congestion based on a location of the network equipment; and identifying a network connection section having a strong possibility of occurrence of congestion based on the type of congestion, and setting a critical congestion bandwidth that is used to determine the occurrence of congestion. Further, the method includes identifying users required for equal distribution of traffic upon occurrence of congestion based on the critical congestion bandwidth; and equally distributing traffic to the identified users based on the critical congestion bandwidth, and then dropping an excess of arriving traffic over the equally distributed traffic, thereby performing avoidance of the congestion.
