Abstract
The present invention relates to a congestion controller, which suppress transmission traffic based on a traffic attribute in the event of congestion especially in a circumstance in which a plurality of Ethernet switches are connected. The congestion controller in the Ethernet switch comprises a plurality of transmission queues having different priority each other, a receiving unit for receiving a PAUSE frame, and a restriction unit to restrict transmission traffic from the transmission queue by the received PAUSE frame, wherein the restriction unit restricts the transmission traffic from a transmission queue of lowest priority by a PAUSE frame received at a time other than a PAUSE time and suppresses transmission traffic from a transmission queue of highest priority by a PAUSE frame received during the PAUSE time.
