  • Patent number: 8780711
    Abstract: A coordinated back-off mechanism for automatic path selection for minimizing race conditions in hybrid communication networks is disclosed. A network device determines a stream medium utilization associated with packet streams for each priority class and network interface of a plurality of communication devices (including the network device). For each priority class and network interface, the communication devices are ranked according to the stream medium utilization. In response to determining that a medium utilization of a network interface exceeds a corresponding medium utilization threshold, the network device determines whether one of its network interfaces originates a packet stream with the greatest stream medium utilization value for a selected priority class. If so, path selection operations are executed to reduce the medium utilization associated with network interface below the medium utilization threshold.

  • Patent number: 8750110
    Abstract: A hybrid network device can implement functionality for automatic path selection and modification in a hybrid communication network. The hybrid network device can select an initial network interface from a plurality of network interfaces for transmitting a packet stream. In response to determining that the medium utilization of the initial network interface exceeds the medium utilization threshold, the hybrid network device can identify one or more packet streams originating from the initial network interface to shift to corresponding one or more alternate network interfaces. The hybrid network device can attempt to reduce the medium utilization of the initial network interface below the medium utilization threshold while maintaining the medium utilization of the one or more alternate network interfaces below the corresponding medium utilization thresholds.

  • Patent number: 5262974
    Abstract: A programmable canonic signed digit (CSD) filter is provided which employs programmable CSD multipliers. The filter receives a digital input signal and includes a tapped delay line for providing a delay between the input samples. The filter advantageously employs a plurality of programmable CSD multipliers which receive programmable input filter coefficients and perform multiplication of the coefficient with the delayed input signal. Summation hardware is further included for summing the outputs of the plurality of multipliers to provide the filter output therefrom.
