The invention discloses a method capable of avoiding network congestion in an SDN network. An SDN controller receives an end port congestion informing message sent by an SDN switching device. The end port congestion informing message carries the end port information of a congestion end port of the SDN switching device. The flow which needs switching of the congestion end port is defined as the switching flow. An upstream SDN switching device of the forwarding switching flow is defined according to the network topology. An updating output port of the upstream SDN switching device is defined. The updating output port is not the original output end port of the upstream SDN switching device, can forward the switching flow to an end port of a link of a destination port, and creates an updating flow table which is matched with the switching flow for the upstream SDN switching device. The output end port of the updating flow table is the updating output end and sends the updating flow to the upstream SDN switching device. After the upstream SDN switching device updates its own flow table, the switching flow is forwarded from the updating output port.
