Abstract: A novel method of operating a Distributed Cable Modem Termination System is provided. Each branch CMTS node in a distributed CMTS supports a complete CMTS system and with full-spectrum ports. One or more MAC domains are defined at each branch CMTS node. A MAC domain defined at a branch CMTS node includes only service flows of the CMs that are connected to the branch CMTS node. Identifiers of service flows coming from a branch CMTS node are always unique, i.e., two different service flows of the branch CMTS would always have different SIDs, even if they belong to different MAC domains. On the other hand, service flows belonging to different branch CMTS nodes are free to reuse the same identifiers.

Abstract: An apparatus includes an optical data transmitter comprising an optical source of temporally incoherent light, an optical power splitter, an optical mode multiplexer, and a plurality of optical paths. The optical power splitter has an optical input and a plurality of optical outputs. The optical input is connected to receive the temporally incoherent light from the source. The optical mode multiplexer has a plurality of optical inputs and an optical output for connecting to a near end of an all-optical transmission fiber line. Each optical path connects a corresponding one of the optical outputs of the optical power splitter to a corresponding one of the optical inputs of the optical mode multiplexer. One or more of the optical paths of the plurality has or have an optical data modulator. A remaining one of the optical paths of the plurality is configured to transmit reference light from the optical power splitter to optical mode multiplexer

Abstract: An apparatus includes a polarization beam splitter (PBS) and an optical detector. The PBS is configured to receive a polarized optical signal transported via an optical communication path of an optical network. The detector is configured to receive from the PBS a first polarization component of the optical signal, and to produce a first electrical measure of the first polarization component. A processor is configured to determine a dynamic metric of the optical communication path based at least on the first electrical measure. Some embodiments also include a second detector configured to receive from the PBS a second polarization component of the optical signal. The second detector produces a second electrical measure of the second polarization component, and the processor is configured to determine the dynamic metric based on both the first and second electrical measures.

Abstract: A network element comprises a memory storing a data structure arrangement. The data structure arrangement includes: an ordered list of asset blocks having a head end and a tail end, each of the asset blocks indicating a number of clients in an access network currently streaming video content of a corresponding channel, the asset blocks being ordered according to the number of clients currently streaming the video content for each channel; and a border structure block storing a pointer to a border asset block within the ordered list of asset blocks, the pointer to the border asset block defining an active set of multicast channels for the access network, and causing the multicast controller to direct a termination node to provide the active set of multicast channels to the clients in the access network.
