    摘要: 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.

    摘要: 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

    摘要: 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.

    摘要: The present disclosure generally discloses improvements in computer performance for supporting a multipath transport throughput capability that is configured to improve throughout of a multipath transport connection of a multipath transport protocol. The multipath transport throughput capability is configured to improve the throughput of the multipath transport connection by improving delivery of acknowledgment packets acknowledging successful delivery of data packets sent from a data transmitting side to a data receiving side. The multipath transport throughput capability may be configured to improve the delivery of acknowledgment packets from the data receiving side to the data transmitting side by, for a data packet that is successfully received at the data receiving side from the data transmitting side, sending multiple acknowledgment packets from the data receiving side to the data transmitting side where the multiple acknowledgment packets associated with the received data packet may be sent over multiple transport connections of the multipath transport connection.
