NETWORK SYSTEM AND NETWORK SWITCHING METHOD

The present disclosure enables a user device to connect to a network via a single edge device out of a plurality of existing edge devices without information being communicated between the edge devices and a device that branches signals and provides branched signals to a plurality of edge devices.A network system according to the present disclosure is a network system in which a plurality of edge devices each have a user acceptance port and a network-side port, the user acceptance ports are connected to a branch device connected to a user device, the network-side ports obtain information on the user acceptance ports, and based on the information on the user acceptance ports, a single edge device out of the plurality of edge devices sets its user acceptance port to be open and be capable of performing traffic transfer with the user device, and the edge devices excluding the single edge device out of the plurality of edge devices set their user acceptance ports to be closed and discard traffic from the user device.
