摘要： The present invention relates to a method for supporting Internet Protocol version 6 (IPv6) in a wireless communication system. According to an exemplary embodiment of the present invention, a wireless communication system consists of an access router, a bridge, and a base station. The access router allocates a common network prefix to all subscriber stations served by it. When receiving IP multicast data destined for all nodes on the same link, the access router forwards the data back to the bridge. The bridge transmits IP multicast data with reference to an identification cache table (ICT) which includes MAC addresses of each subscriber stations, identifiers for point-to-point connections between the bridge and base station, IPv6 addresses of each subscriber station and valid flags for the IPv6 addresses. The base station provides point-to-point connections to both the bridge and each of subscriber stations.

摘要： A data transmission system in an EPON includes a parser classifying frames generated in each block, and transmitting the frames to a block. A scheduler performs multiplexing of frames, then, during a transmission time permitted by an OLT, determines a transmission sequence of the frames and transmits the frames. A MPCP slave processes messages transmitted from the OLT, generates response messages on the transmitted messages, and maintains time synchronization with the OLT A processor interface conveys frames transmitted from the OLT to a processor, frames primitives transmitted from the processor, and transmits the primitives to the OLT. A register stores a value used during generation of frames in each block, a value for system control, and a value acquired from MPCP control frames.

摘要： A method of controlling a Forward Error Correction (FEC) operation including: configuring a FEC frame to be transmitted between an OLT and an ONU comprising a FEC frame identifier indicating whether FEC should be performed, data, a first flag indicating that FEC should be performed, and a second flag indicating that the FEC frame is to be FEC encoded; initializing the OLT by disabling a FEC function; determining whether the ONU requires FEC to be performed based on a FEC frame identifier received from the ONU; IPG stretching the FEC frame when the ONU requires to FEC to be performed; and transmitting the FEC frame to the ONU after FEC encoding based on the second flag of an input frame to a PCS sublayer from an upper layer. The method controls an effective operation of a FEC of an ONU and an OLT without changing a Round Trip Time (RTT) according to optical link quality in an EPON. Accordingly, FEC is used only if necessary, thereby simplifying the managing of a link, and preventing an excessive 35% reduction of throughput caused by use of unnecessary FEC.

摘要： There is provided a method for supporting a multicast service in an Ethernet passive optical network system. Since an Optical Network Unit (ONU) system monitors an IGMP (Internet Group Management Protocol) message and informs the monitored result of an Optical Line Terminal (OLT) system so that the OLT system creates L2 multicast forwarding table using a multicast address and ONU ID information in a PON port, the ONU system transmits the multicast packet only to a corresponding subscriber on the basis of the L2 multicast forwarding table when receiving a multicast packet. Therefore, it is possible to transfer a multicast packet only to a specific ONU system belonging to a corresponding multicast address group among a plurality of ONU systems.

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.
