ABSTRACT:
In a congestion control method for a system having a first network of one congestion control unit representing a subset of a switching network constituted by a set of switching nodes connected to each other and a second network which serves as a subset of the switching network and does not have a switching node common to the first network, thereby controlling congestion of the first and second networks, the traffic is classified into first traffic generated in the first network and reaching a target switching node of the first network through a switching node in the first network, second traffic having the switching node of the first network as a start point and directed toward the second network, third traffic having a switching node in the second network as a start point and transmitted through a switching node in the second network and a switching node in the first network, and fourth traffic which does not correspond to any one of the first traffic, the second traffic, and the third traffic. Upon occurrence of congestion in the first network, the traffic flow amounts and traffic rates of the first traffic and the second traffic are limited in the first network.
