Abstract
In a relaying apparatus detecting a congested state and performing a flow control, an output buffer using an up-link or a stack-link is monitored. When the up-link or the stack-link is in a congested state, a transmission restriction is imposed on a port which is a transmitting source of a corresponding frame. Furthermore, when a plurality of relaying apparatuses are connected through stack-links, the relaying apparatus having the up-link detects the congested state of the up-link and notifies a second relaying apparatus of the congested state to make a transmission restriction.
