  • Patent number: 9998389
    Abstract: A network device including first and second queues, a timing module and a shaper. The first queue receives first frames. The second queue receives second frames. A priority level of the second frames is lower than a priority level of the first frames. The timing module determines a start time of a burst period of the first frames. The first frames are transmitted from the network device during the burst period. The shaper determines: a size of a head-of-line frame of the second frames; a predetermined maximum size of one of the second frames; or a predetermined minimum size of one of the second frames. The shaper determines whether to block transmission of the head-of-line frame from the network device based on (i) the start time, (ii) the size of the head-of-line frame, (iii) the predetermined maximum size, or (iv) the predetermined minimum size.

  • Patent number: 9967306
    Abstract: A method for prioritized transmission of redundancy data in a voice-over-packet call. A sending device applies a variable rate codec to generate a sequence of encoded voice frames having varying sizes, and the sending device inserts the encoded voice frames into a sequence of fixed-size packets, one encoded voice frame per packet, resulting in varying left-over payload capacity per packet. The sending device further generates based on each encoded voice frame multiple redundancy blocks to help facilitate recovery of the encoded voice frame. And on a per packet-basis, the sending device selects, from a sliding-window set of recently generated redundancy blocks, one or more redundancy blocks to add into the left-over payload capacity of the packet, with the selecting of each redundancy block being based at least on importance of the voice frame based on which the redundancy block was generated, and the age and size of the redundancy block.

  • Patent number: 9942151
    Abstract: At an application executing in conjunction with a vSwitch in a host system, using a processor assigned to the vSwitch in the host system, a CWND value is computed corresponding to a flow from a VM using a period measured by a timer and a number of packets of the flow received and acknowledged in response packets, the number being counted by a counter, the timer being associated with a packet of the flow. The CWND value is stored in a field in a response packet received from a receiver of the flow, the field being designated for carrying a RWND value, the response packet corresponding to a packet in the flow. The storing forms a modified response packet. The modified response packet is sent from the vSwitch to the VM.

  • Patent number: 9900251
    Abstract: Minimum guaranteed wireless network bandwidth is provided to client network devices by monitoring the performance of network connections to identify client network devices experiencing network congestion. Congested network connections are then analyzed to determine the source of the network congestion. Depending upon the source of the network congestion, an embodiment of the invention may undertake steps to either improve the quality of the network connection or to mitigate the impact of this network connection on other network connections. High quality network connections may be allocated additional bandwidth, airtime, or other resources to reduce the network congestion. Low quality network connections are not allocated additional bandwidth, airtime, or other resources. Instead, the impact of this network connection on the other network connections is mitigated.

  • Patent number: 9848439
    Abstract: A method and apparatus for signaling the release of a persistent resource in long term evolution (LTE) are disclosed. An indication of the release of a downlink (DL) persistent resource is received by a wireless transmit receive unit (WTRU) from an evolved Node-B (eNB) via a physical downlink control channel (PDCCH). A positive acknowledgement (ACK) is transmitted by the WTRU which denotes that the indication has been received. The PDCCH or a medium access control (MAC) CE may be used by the eNB to signal the indication. At least one bit may be added to contents of the PDCCH to signal whether the PDCCH is for DL persistent or dynamic resource allocation. The DL persistent resource is then released and an indication that the DL persistent resource has been released is transmitted.
