摘要： A method of controlling data transmission in an Ethernet passive optical network (EPON) and an apparatus thereof are provided. Transmission permission messages using a mode of bandwidth allocation are queued in a queuing unit according to the types of the transmission permission messages. A transmission time duration of upstream data is defined for each of the transmission permission messages queued in the queuing unit. A bandwidth allocation unit generates transmission permission messages to allocate upstream data transmission bandwidth for an optical network unit (ONU), based on the transmission permission messages stored in the storage unit. A scheduler designates the predetermined priority, reads transmission permission messages from queues according to a predetermined priority, determines a transmission start time of upstream data, and outputs the transmission permission messages.

摘要： PURPOSE: A method for transceiving a variable-length packet is provided to enable a transmission circuit to know length of a packet to be transmitted before transmitting packet data, and to enable a CPU to know the length of the packet before reading the packet data, thereby easily programming software for realizing a variable-length packet transceiving function. CONSTITUTION: If an outer CPU tries to transmit a variable length packet, the CPU transmits the packet to a transmission data FIFO, so that the transmission data FIFO can store the packet(S210). The transmission data FIFO stores length information of the received packet in a transmission size FIFO(S220). As soon as size information is written in the transmission size FIFO, a transmission packet counter storage increases a transmission packet counter by 1, and informs a transmission circuit that the one packet is written(S230). The transmission circuit firstly reads the length information of the packet from the transmission size FIFO, and reads the substantial packet from the transmission data FIFO (S240). The transmission packet counter storage monitors a read signal, and decreases the transmission packet counter by 1 after reading the one packet(S250).

摘要： PURPOSE: An ONU(Optical Network Unit) request transmission method in an Ethernet-phone structure is provided to be continuously informed on status of an ONU from an uplink data frame by adding uplink request information of the ONU to the preamble of an Ethernet frame. CONSTITUTION: A MAC layer(21) has a MAC control function of IEEE802.3 and additionally includes an MPCP(Multi-Protocol Control Protocol), a transmission control function of an E-PON(Ethernet-Passive Optical Network). An RS(Reconciliation Sublayer)(23) performs a P2PE(Point-to-Point Emulation) function and an OAM(Operation and Management) function for allowing ONUs belonging to an OLT(Optical Line Terminal) domain to communication with each other, and an information insertion/extraction function of the ONU. The ONU performs a frame filtering function using a physical ID and a MAC preamble recovery function. The physical ID is assigned by an Ethernet PON OLT. An RS(26) compares a physical ID of a preamble of a frame received from an OLT and its own physical ID, and sends it to an upper layer(25) or discards it according to a mode of the received frame. When the ONU receives grant for transmission from the OLT, it indicates its request information in a preamble of a subscriber Ethernet frame to be transmitted to the OLT and transmits it. the OLT collects request information of each ONU from the preambles of Ethernet frames and transmits it to a MAC control layer(24).
