Abstract: PURPOSE: A method of flushing a filtering database in a multiple Ethernet ring network is provided to effectively flush a filtering database without error in the multiple Ethernet ring network when a topology of a lower ring network is changed in a multiple ring network. CONSTITUTION: If an upper ring network is not normal, a flush trigger message is transmitted to a port receiving the flush trigger message(S340). The flush message is transmitted to a port to which the upper ring network is connected(S210). If a message included in a protection switching frame is a topology change signal of a lower ring network(S400), one of the flush message and the flush trigger message is transmitted to the port to which the upper ring network is connected according to a state of the lower ring network(S430).

Abstract: PURPOSE: A protection switch method of multiple rings for performing protection switching is provided to prevent the generation of unnecessary traffic for reconfiguration of filtering database by determining the removal of filtering database in reference with a topology table. CONSTITUTION: Color information of low rank ring network is allocated about lower ring networks. A topology table of the node is generated through color information of the lower network and the color information in a block port(12). If the topology of the low rank ring is changed, the elimination of the filtering database is determined with reference to the topology table.

Abstract: PURPOSE: A protection switching method is provided to prevent the overshooting of traffic amount after protection switching through the initialization of transfer table information in the case of performing the protection switching operation in an Ethernet ring network. CONSTITUTION: If a network topology is changed, plural nodes(100,200,300,400,500,600) delete an address list connected to a ring network in delivery tables(130,230,330,430,530,630). Plural nodes transmit each subnet address list, and update each delivery table based on the subnet address list. If the failure is recovered on a link, an NR_APS(No Request-Automatic Protection Switching) frame is created. The created recovery protection switching frame is transmitted.

Abstract: PURPOSE: A method for flushing a filtering database in an Ethernet ring network is provided to remove an FDB(Filtering DB) without an error. CONSTITUTION: A node receives a protection switching command or detects a signal fault. The node judges whether or not the state thereof is transited into a protection switching state requested by a signal failure or protection switching command. The node compares priority between the protection switching state and the current state(S632). If the priority of the protection switching state has higher priority than the current state, the node is transited into the protection switching state(S634). If the transition operation is performed, the node removes the FDB(S640).

Abstract: PURPOSE: A transferring table update method in a multi ring network saving resources by the reduction of the use of the unnecessary bandwidth and buffer is provided to minimize overshoot transition by selectively removing the transferring table. CONSTITUTION: If a ring connection node senses a topology change, the ring connection node removes a transfer table(S21). The ring connection node initializes the marking of a removal flag and a block flag(S24). The ring connection node sets up ring ID information of a sub ring to a ring ID field within a removal command protection switching frame(S25). The ring connection node multicasts the removal command protection switching frame(S26).
