    Abstract: PURPOSE: A method for generating a multicast LLID(Logical Link ID) in an EPON(Ethernet Passive Optical Network) is provided to assign a proper LLID to multicast traffic, and to receive the multicast traffic in an EPON, then to apply a multicast group member to the EPON, thereby performing an address filtering process in an application layer. CONSTITUTION: A mapper(110) of an OLT(Optical Line Terminal)(100) inserts a multicast address into a hash function, forms the inserted multicast address in 14 bits, and uses the multicast address as contents of an ID field of an LLID(300). The mapper(110) of the OLT(100) uses the rest 2 bits as multicast mode bits with unicast. If the OLT(100) transmits the generated multicast LLID(300) to ONUs(Optical Network Units)(110-n), emulation layers(206) of the ONUs(110-n) perform filtering processes by seeing the multicast LLID(300) transmitted from the OLT(100).

    Abstract: PURPOSE: A redundant system and method for a GE-PON(Gigabit Ethernet Passive Optical Network) and a frame structure for controlling the same are provided to achieve the path transfer between an OLT(Optical Line Terminal) and a 2xN splitter and to control the path transfer. CONSTITUTION: An ONU(Optical Network Unit) checks a signal environment and detects an SF/SD. The ONU generates an OAM(Operation, Administration, and Maintenance) frame for a transfer request according to a checked result and transmits a packet, including the OAM frame, to an OLT. The OLT receives the packet and detects the transfer request. In response to the transfer request, the OLT transfers the present working path to a protection path and transfers the protection path to the working path.

    Abstract: PURPOSE: A method for additionally registering ONUs(Optical Network Units) in a GE-PON(Gigabit Ethernet Passive Optical Network) and an Ethernet frame structure are provided to offer an additional ONU registration method required for the embodiment of GE-PON in a PON structure. CONSTITUTION: An OLT(Optical Line Termination) downlinks normal frames to a plurality of registered ONUs in order to provide a bandwidth allocation request opportunity to them(300). Each ONU uplinks a bandwidth allocation request frame at the bandwidth allocation request start point of the next cycle. The OLT collects bandwidth allocation requests from the registered ONUs(302), and executes scheduling for the requested bandwidths using a scheduler(304). Then the OLT compares BW_tot, a total available bandwidth, with BW_alloc, an allocation-requested bandwidth(306). If the difference between BW_tot and BW_alloc is larger than 208us(308), the OLT downlinks a grant frame for additional registration(312). Then, after waiting during the time of registration offset + frame time + slot position + down-stream delay time, the OLT judges whether a registration request frame is received(316).
