VLAN AWARE SHARED LAN EMULATION METHOD AND DEVICE WITH MANAGEABLE LLID IN EPON

摘要

The present invention relates to an Ethernet passive optical network (EPON) point-to-point (P2P) LAN Emulation method using a logical link identifier (LLID) to be used for communication and broadcasting function in the device, and. Shared LAN Emulation method according to the present invention, a unique logical link identifier (LLID) for each of the optical network unit (ONU) in order to distinguish the plurality of optical network units (ONU) connected to one of the optical termination unit (OLT) and establishing a logical link identifier (LLID) management table for managing the allocation, the method comprising a said logical link identifier (LLID) set to the MAC address table for learning the MAC address of the optical network unit (ONU), assigning the optical network unit (ONU) is the unique logical link identifier (LLID) to the registered optical network unit (ONU) requested in the request to register to the optical termination unit (OLT), and the light to provide a matched port in between the logical link control layer (LLC) and MAC layers in the termination unit (OLT), a predetermined group of the VLAN and the logical link identifier (LLID), belongs to the optical network unit (ONU) using a destination MAC address of the ID and the data frame is characterized in that it comprises the step of bridging the data frame is received in a shared LAN emulation layer in the optical termination device (OLT). ; EPON, OLT, ONU, SLE, LLID, VLAN number, VID, a shared LAN emulation
