Abstract: A method for updating a filtering database in a multi-ring network, includes: when the topology of a lower ring in a multi-ring network, in which a plurality of ring networks are connected by two ring connection nodes, is altered and the ring connection node detects the alteration in the topology of the lower ring, erasing, by the ring connection node, its filtering database; generating, by the ring connection node, a control message including a ring ID, a blockage flag, and an erasure flag; transmitting the control message in both directions of the ring; and determining, by a node which receives the control message, to erase a filtering database by referring to and correcting the blockage and erasure flag information included in the control message.

Abstract: A method for protection switching of a ring network, which includes a plurality of nodes disposed in a ring shape, includes: allowing a node adjacent to a failure link among the plurality of nodes to generate a failure protection switching frame when the failure link is generated in the ring network; allowing the node adjacent to the failure link to transmit the failure protection switching frame to an adjacent node; allowing each of the plurality of nodes to delete address lists connected with the ring network except for an external network (hereinafter referred to as subnet) from their own forwarding table; allowing each of the plurality of nodes to transmit a subnet address list protection switching frame including a subnet address list; and allowing a node receiving the subnet address list protection switching frame to update the forwarding table on the basis of the subnet address list included in the frame.
