Abstract:
1. A method comprising: receiving, with an optical line terminal (OLT) a data unit that includes a header specifying a virtual local area network (VLAN) tag, wherein the OLT couples to one or more optical network terminals (ONTs) via one or more different logical interfaces supported by a single physical interface, determining, with the OLT, whether the received data unit is a candidate for replication to create multiple copies of the data unit based on the VLAN tag specified in the header of the data unit; performing, with an inline packet processing module located in a data path of the OLT, replication to generate at least one copy of the data unit based on the determination that the received packet is a candidate for packet replication; and outputting, with the physical interface of the OLT, the at least one copy of the data unit to the one or more ONTs.
