ABSTRACT:
A topology database stores the number of RPR nodes which belong to an RPR network. A traffic rate measuring unit sends a variety of parameters for calculating a communication band available to a fairness controlled traffic packet to a fairness control unit. Upon detection of congestion, the fairness control unit calculates a communication band available for transmission of the fairness controlled traffic packet from the parameters sent from the traffic rate measuring unit, divides the communication band by the number of nodes to find an initial value for a fair rate.
