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 Dynamic bandwidth allocation method using OLT (Optical Line Terminal) and ONU (Optical Network Unit) for use in GE-PON (Gigabit Ethernet Passive Optical Network) system is disclosed. The OLT's scheduler performs scheduling upon receiving multiple-queue request information contained in the REPORT message from the ONU, and transmits a combined scheduling result associated with one ONU using a GATE message. An ONU's scheduler performs scheduling upon receiving a bandwidth allocated by the OLT, and allocates a transfer bandwidth to its own queues.

摘要： A GE-PON (Gigabit Ethernet Passive Optical Network) system and media access control method for the same are disclosed. In the GE-PON system, by employing MAC attributes of the gigabit Ethernet frames, an OLT (Optical Line Termination) transmits a downstream window containing both a control frame having timeslot position and size information in association with at least two ONUs and Ethernet frames to an ODN (Optical Distribution Network). The OLT analyzes contents of RAUs in an upstream window transmitted from the ONUs in a TDMA method and received from the ODN, and permits timeslot position and size corresponding to each of the ONUs. A plurality of ONUs, connected to the ODN, have their respective timeslot position and size allocated in response to their respective information contained in the control frame of the downstream window. RAU frames are transmitted having queue information and Ethernet frames associated with the allocated timeslots. As a result, by the above MAC structure of the GE-PON system, the OLT can be quickly intercommunicated with a plurality of ONUs.

摘要： A method for upstream traffic control in an Ethernet-based passive optical network, adapted for preventing a penalty phenomenon occurring in making upstream data transfer on basis of High Priority First Allocation (HPFA) algorithm. The method includes the steps of determining whether are any data frames to transfer in the first buffer; if it is determined that there are any data frames to transfer in the first buffer, determining whether the data frame does not exceed a low water mark indicative of a reference value set up to ensure the minimum transfer traffic; if it is determined that the data frame in the first buffer does not exceed the low water mark, then transferring the data frame stored in the first buffer and determining whether the data frame in a second buffer does not exceed the low water mark; if it is determined that the data frame in the second buffer does not exceed the low water mark, then determining whether the data frame to transfer in a third buffer does not exceed the low water mark; if it is determined that the data frame to transfer in the third buffer does not exceed the low water mark, then transferring the respective data frame stored in the second and third buffers.
