Abstract: A node device and a method for path switching control in the same are provided that can achieve easier network maintenance, reduced loads on the network, and faster path switching in the event of a failure. A node device includes a storage section for storing a forwarding table (FDB) and a management table (RDB), wherein the forwarding table associates a destination node device of forwarded data with an address of the destination node device on the ring network, wherein the management table associates the destination node device with port information on a port to be used for forwarding data to the destination node device; and a control section for updating an association of the destination node device with the port information in the management table without changing the forwarding table when a transfer path of the forwarded data is changed.
