  • MULTICAST TRAFFIC BRIDGING
    Publication number: 20150326405
    Abstract: A fiber-coax unit (FCU) is coupled to an optical line terminal (OLT) and a plurality of coax network units (CNUs). The FCU receives a multicast frame from the OLT. The multicast frame includes a first multicast logical link identifier (LLID) dedicated for multicast traffic directed to CNUs. The FCU replaces the first multicast LLID in the multicast frame with a second multicast LLID corresponding to one or more multicast groups that include at least one CNU of the plurality of CNUs. The FCU transmits the multicast frame to the plurality of CNUs.

  • Multi-point control protocol proxy architecture in a network with optical and coaxial domains
    Patent number: 9071380
    Abstract: A method of registering a coax network unit (CNU) in a network is performed at an optical-coax unit (OCU). In the method, a first discovery message is broadcasted to a plurality of CNUs. In response, a first registration request is received from a first CNU of the plurality of CNUs. In response to the first registration request, a proxy entity corresponding to the first CNU is implemented in the OCU. A second discovery message is received from an optical line terminal (OLT). In response to the second discovery message, a second registration request is transmitted to the OLT requesting registration of the proxy entity with the OLT.
