摘要： Disclosed is a point-to-point emulation method for operating an Ethernet passive optical network having an optical line terminal (OLT) and a plurality of optical network units (ONUs) each connected to the OLT. A tag Ethernet frame transmitted between the OLT and the ONUs includes a destination address (DA) field representing a destination address, a source address (SA) field representing a source address, and an LLID field in which a unique LLID assigned to an object of the ONU side is recorded. The LLIDs are assigned to ports of a bridge or an L2 (Layer 2) switch of the OLT side on a one-to-one basis. The OLT, upon receiving a tag Ethernet frame, outputs an LLID field-deleted Ethernet frame to the bridge or L2 switch port to which an LLID in the received frame is assigned. The bridge or the L2 switch transmits the Ethernet frame to a port to which a previously learned destination address is assigned. The OLT regenerates a tag Ethernet frame by inserting into the Ethernet frame an LLID field in which an LLID of the destination ONU is recorded. The regenerated tag Ethernet frame is transmitted to the destination ONU.

摘要： A method of controlling a loop-back process between a local device and a remote device in an Ethernet passive optical network simplifies the initiation and the termination processes for a loop-back process by avoiding the use of Operation, Administration and Maintenance—Packet Data Unit (OAM PDU) information along with a loop-back control OAM PDU. The method includes the steps of: (a) adding a predetermined field into a loop-back control OAM PDU in the loop-back process, the predetermined field having distinguishing messages for initiation of a loop-back process and messages for termination of a loop-back process; and (b) the local device and the remote device performing a loop-back process using the loop-back control OAM PDU.

摘要： Disclosed is a method and apparatus for controlling downstream traffic in an EPON (Ethernet Passive Optical Network). Individual tokens respectively for ONUs (Optical Network Units) are generated and stored, and a common token based on a total transfer rate of the EPON is generated and stored. In order to transmit downstream data, it is determined whether the downstream data is transmittable first by the corresponding individual token, and then second by the common token if the first determination is negative. In the case where traffic is concentrated on an ONU at a time, even if downstream data cannot be transmitted by an individual token for the corresponding ONU, the common token not used by other ONUs can be used to transmit the downstream data. It is thus possible to guarantee minimum/maximum transfer rates to all ONUs and ensure QoS against burst traffic in the EPON.
