  • Patent number: 9742495
    Abstract: Disclosed are techniques for timing correction for a DOCSIS Edge-QAM. Unlike the DTI required at the headend in existing solutions for DOCSIS Edge-QAM timing, the disclosed techniques may use an Edge-QAM timing deeper in to the network. The N-QAM, referring to an Edge-QAM that is deeper in the network, may be in the optical node configured to convert signals from a network headend or hub for delivery to a subscriber network element. The N-QAM device located in the node may include a local clock for deriving a local time for incoming transport streams, modulating the transport streams onto a downstream carrier for delivery to subscriber network elements using the local clock time, and adjusting the local clock time based on an average value of timestamps in the incoming transport streams.

  • Patent number: 9730225
    Abstract: A wireless communication base station device which makes it possible to provide a base station, terminal and CCE allocation method capable of reducing the number of times blind decoding of a terminal is performed, without increasing the CCE block rate, even when a plurality of unit bands are set in a terminal. In this device, a search space setting section (103) sets in each of a plurality of unit bands a common search space in respect of a terminal which is communicating using the plurality of unit bands and other terminals, and sets in each of the plurality of unit bands an individual search space in respect of the terminal. An allocation section (106) allocates control information solely to CCEs within the common search spaces set in specified unit bands among the plurality of unit bands, or solely to CCEs within individual search spaces set in specified unit bands.

  • Patent number: 9634940
    Abstract: A method includes receiving in a network switch of a communication network communication traffic that originates from a source node and arrives over a route through the communication network traversing one or more preceding network switches, for forwarding to a destination node. In response to detecting in the network switch a compromised ability to forward the communication traffic to the destination node, a notification is sent to the preceding network switches. The notification is to be consumed by the preceding network switches and requests the preceding network switches to modify the route so as not to traverse the network switch.

  • Patent number: 9571426
    Abstract: Some embodiments provide a queue management system that efficiently and dynamically manages multiple queues that process traffic to and from multiple virtual machines (VMs) executing on a host. This system manages the queues by (1) breaking up the queues into different priority pools with the higher priority pools reserved for particular types of traffic or VM (e.g., traffic for VMs that need low latency), (2) dynamically adjusting the number of queues in each pool (i.e., dynamically adjusting the size of the pools), (3) dynamically reassigning a VM to a new queue based on one or more optimization criteria (e.g., criteria relating to the underutilization or overutilization of the queue).
