  • System and method for improving resilience in transmission of data fragments
    Patent number: 9578142
    Abstract: A system and method packetizes data by fragmenting, with processing circuitry, a data structure into a plurality of data fragments, each data fragment being included in a separate packet, and inserting, with processing circuitry, an offset indicator within each of the packets, each offset indicator indicating an amount of fragment data encapsulated within preceding packets. A system and method decodes packetized data that includes the offset indicator.
    Type: Grant

    Date of Patent: February 21, 2017
    Assignee: Cisco Technology, Inc.
    Inventors: Paul Bright Thomas, Thomas Davies, Mohamed Kamel Zanaty
  • Network switch employing a proxy to facilitate power savings in a telephone network
    Patent number: 9065685
    Abstract: In an example embodiment, an IP phone is connected to a network switch that has an established communications channel to a call control server. The network switch acts as a proxy for the phone exchanging registration information that in effect keeps the phone registered while the phone itself can go to sleep as defined by periods of the day, periods where the phone is unused, or presence, which can then wake-up quickly with assistance from the switch. If the switch is not able to act as proxy, the phone can switch from sleep mode to “wake” up mode at predetermined intervals, such as every 30 seconds, in order to respond to keep alive packets from the call control server.
