摘要： Devices, systems and methods that measure at least one of the latency and the jitter experienced over a defined portion of a path between a sending device and a receiving device. A network monitoring unit is located between the sending and receiving devices, and monitors packets exchanged between the two to measure the latency and/or jitter.

摘要： Devices, systems and methods that determine both the existence of, and location where, packets were dropped in transit between a sending device and a receiving device. A network monitoring unit is located between the sending and receiving devices, and monitors packets exchanged between the two to determine the location where packets were dropped.

摘要： Devices, systems, and methods that identify and mark traffic intended to pass through a network with low latency relative to other traffic through the network. The devices, systems, and methods may include a first low latency DOCSIS (LLD) agent that identifies characteristics of low latency packets and/or a second LLD agent that uses the characteristics to identify low latency traffic and mark it for low latency treatment in the network.

摘要： An apparatus for implementing soft duplex operation of a communications network that transmits downstream signals from a service provider to a subscriber and upstream signals from the subscriber to the service provider. The apparatus may include a pair of opposed triplexers defining a first signal path through a first amplifier and a second signal path through a second amplifier. The apparatus may also include at least one switch that selectively alternates a mid0band signal between an upstream signal and a downstream signal.

摘要： A Data Over Cable Interface Specification (DOCSIS) node includes a first DOCSIS port and a second DOCSIS port. The node also includes a plurality of radio frequency (RF) ports. A plurality of client devices can be coupled to the RF ports. A RF switching network is coupled between the first DOCSIS port and the second DOCSIS port, and the plurality of RF ports. One or more control circuits can switch the RF switching network between at least a first state and a second state. The switching of the RF switching network allows the one or more control circuits to identify which client devices are coupled to which RF ports of the node.

摘要： Systems and methods for relaying a plurality of data packets to and from a subscriber over an access network that imparts a variable latency of one packet relative to other packets. The latency of each packet is controlled so as to increase the average latency experienced by the plurality of packets and decrease the variance of the respective latencies experienced by each of the packets.

摘要： In some embodiments, a method receives a first signal that is sent in a first direction in a network. Communications in the network are full duplex communications in a same frequency band. The first signal is amplified in the first direction. The method trains a first echo canceller to cancel a first echo signal from the first signal where the first echo signal is received in a second direction. After training the first echo canceller, the trained first echo canceller is enabled. The method receives a second signal in the second direction that is sent in the second direction in the network. The second signal is amplified in the second direction. The method trains a second echo canceller to cancel a second echo signal received in the first direction from the second signal where the first echo canceller cancels the first echo signal that is received in the second direction.
