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.

Abstract: In a wireless optical communication system in which communication is performed based on a free space and a plurality of the communication apparatuses are arranged in a ring form around a central office terminal (COT), the communication apparatus monitors optical signals received in a first direction or in a second direction opposite to the first direction, and selects a first path through which the optical signals in the first direction are received and a second path through which the optical signals in the second direction are received. The communication apparatus converts an optical signal having a predetermined unique wavelength from among the optical signals received through the selected path into a signal of a frequency domain having a plurality of subcarriers, and obtains packet data mapped to each of the subcarriers.
