LOGICAL UNICASTING TECHNIQUE IN PASSIVE OPTICAL NETWORKS

摘要

PURPOSE: A unicasting technique in a PON(Passive Optical Network) is provided to perform peer-to-peer transmission in an Ethernet PON system. CONSTITUTION: A certain port of an OLT(Optical Line Termination)(30) is allocated in an ONU(Optical Network Units)(32a-32d). An Ethernet frame including a certain ONU as the destination location is received to the OLT. An ONU ID indicating the certain ONU allocated to the port is included in an Ethernet type of the Ethernet frame. A PON tagging Ethernet frame is generated. The PON tagging Ethernet frame is outputted through the port connected to the certain ONU.
