摘要： Disclosed is a upstream data transmission method in a gigabit Ethernet-passive optical network (GE-PON) system. In the GE-PON system including an optical line termination having a scheduler and optical network units connected to the optical line termination, the optical line termination receives bandwidth allocation request signals from the optical network units at a start of a first cycle, allocates transmission bandwidths to the respective optical network units in accordance with the bandwidth allocation request signals, and transmits the allocated transmission bandwidths to the respective optical network units before a second cycle that follows the first cycle.

摘要： In an Ethernet passive optical network (EPON) system and a method for setting up a bandwidth therein, the EPON system comprises at least one optical network unit (ONU) for transmitting to an optical line termination (OLT) a registration request message containing information about a set second bandwidth when a discovery gate message according to a multi point control protocol (MPCP) is received. The OLT registers the ONU therein according to information about a set first bandwidth and the information about the second bandwidth contained in the registration request message received from the ONU. The EPON system registers only the ONU having an optimum bandwidth in a network environment where the OLT and the ONU have different bandwidths from each other.

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.

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.
