Patent ID: 8638807

Claim:
A method for managing an Ethernet ring network of a VLAN-based bridge, comprising: registering a major-ring VID (VLAN ID) in a ring port filtering database of a ring protection link owner node in accordance with a request for registering the major ring VID (VLAN ID) from an ERP (Ethernet Ring Protection) controller mounted on the ring protection link owner node of a major ring; delivering, by the ring protection link owner node, a VID registration message to other nodes which belong to the major ring through a ring port; receiving the VID registration message through the ring port and registering the major ring VID in a ring port filtering database of each node itself, by each node which belongs to the major ring; delivering, by each node which belongs to the major ring, the VID registration message to other nodes which belong to the major ring through the ring port; and when a VID requiring an ERP service among VIDs registered in each node which belongs to the major ring exists, requesting, by an ERP controller of a node in which the VID requiring the ERP service is registered, registration of the VID; registering the VID in a ring port filtering database of the node in which the VID requiring the ERP service is registered; delivering, by the node in which the VID requiring the ERP service is registered, a VID registration message to other nodes which belong to the major ring through the ring port; receiving the VID registration message through the ring port and registering the VID in the ring port filtering database of the each node itself, by the each node which belongs to the major ring; and delivering, by each node which belongs to the major ring, the VID registration message to other nodes which belong to the major ring through the ring port.
