Abstract: Systems and methods relying on recognition of a pattern in a data stream, such as detecting a hotword in an audio data stream are sensitive to latency (e.g., response time). To reduce power consumption, a low power processor may be used in combination with a higher power speech recognition device. When the hotword is detected by the low power signal processor, the primary speech recognition device is signaled to wake up and begin emptying a buffer storing the hotword and subsequent audio data. Latency is the delay incurred to recognize the hotword and begin emptying the buffer. To catch-up and reduce the latency, the buffer is drained at a faster rate than the buffer is filled until a latency reduction trigger is received. The latency reduction trigger is generated when the latency has been reduced to a predetermined level.

Abstract: To more efficiently utilize buffer resources, schedulers within a traffic manager may generate and queue read instructions for reading buffered portions of data units that are ready to be sent to the egress blocks. The traffic manager may be configured to select a read instruction for a given buffer bank from the read instruction queues based on a scoring mechanism or other selection logic. To avoid sending too much data to an egress block during a given time slot, once a data unit portion has been read from the buffer, it may be temporarily stored in a shallow read data cache. Alternatively, a single, non-bank specific controller may determine all of the read instructions and write operations that should be executed in a given time slot. The read instruction queue architecture may be duplicated for link memories and other memories in addition to the buffer memory.

Human intervention is minimized by augmented decision making ability in selecting what aspects of large datasets should be focused on to drive key business outcomes.

Abstract: An I/O management method includes determining local target I/O rates for a plurality of storage controllers across which an I/O stream is distributed. The local target I/O rates may reflect a target latency corresponding to a QoS attribute associated with the I/O stream. A cumulative target I/O rate may be determined based on the local target I/O rates. A token bucket rate may be calculated for each applicable storage controller based on the local target I/O rates.

The local target I/O rates may be determined periodically based on measured data indicating actual latency and traffic. A queue depth is determined based on the measured values of latency and traffic. The queue depth is then used with the desired value of latency to obtain the target I/O rates.

Abstract: Methods and systems for managing packet flow in a local network in a manner that allows network devices at the edge of the network to use minimal buffer memory while maximizing use of bandwidth allocated on an interconnect between the local network and an external network. Packet flows facing external network problems are scaled back, reducing redundant traffic on the interconnect and allowing for use of small buffers in edge devices. A flow source marks a subset of packets within a flow for preferential treatment within the local network. The flow source then adjusts the flow rate only responsive to failures in transmission of the marked packets. In some implementations, an edge device removes the markings prior to packet egress. The local network honors the preferential treatment markings such that a loss of a marked packet is more likely to occur on an external network than on the local network.

The controller adjusts the load balancing algorithm based on the fed back information for selection of core switches for a subsequent data flow.
