Method for managing ethernet ring network of vlan-based bridge

Abstract

There is provided a method for managing an Ethernet ring network of a VLAN-based bridge that includes: 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; 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.

What is claimed is: 
     
         1 . 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; 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.   
     
     
         2 . A method for managing an Ethernet ring network of a VLAN-based bridge, comprising:
 registering a sub-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 sub ring VID (VLAN ID) from an ERP (Ethernet Ring Protection) controller mounted on the ring protection link owner node of a sub ring;   delivering, by the ring protection link owner node, a VID registration message to other nodes which belong to the sub ring and major ring through a ring port;   receiving the VID registration message through the ring port and registering the sub ring VID in a ring port filtering database of each node itself, by each node which belongs to the sub ring and major ring; and   delivering, by each node which belongs to the sub ring and major ring, the VID registration message to other nodes which belong to the sub ring and major ring through the ring port.   
     
     
         3 . A method for managing an Ethernet ring network of a VLAN-based bridge, comprising:
 setting ring ports of an Ethernet ring node constituting an Ethernet ring, wherein a ring ID of the Ethernet ring is set;   determining whether the Ethernet ring node is a ring protection link (RPL) owner node or an RPL neighbor node, wherein an RPL is located between the RPL owner node and the RPL neighbor node;   registering VLAN IDs (VIDs) for performing a traffic channel blocking and a Ring Automatic Protection Switching (R-APS) channel blocking in Filtering Databases (FDBs) of the ring ports of the Ethernet ring node; and   performing a topology update of the Filtering Databases.
