  • Methods and apparatus for flow control associated with a switch fabric
    Patent number: 11398991
    Abstract: In some embodiments, an apparatus includes a switch fabric having at least a first switch stage and a second switch stage, an edge device operatively coupled to the switch fabric and a management module. The edge device is configured to send a first portion of a data stream to the switch fabric such that the first portion of the data stream is received at a queue of the second switch stage of the switch fabric via the first switch stage of the switch fabric. The management module is configured to send a flow control signal configured to trigger the edge device to suspend transmission of a second portion of the data stream when a congestion level of the queue of the second switch stage of the switch fabric satisfies a condition in response to the first portion of the data stream being received at the queue.

  • Systems and methods for automated sensor polling
    Patent number: 8266343
    Abstract: A device may include polling logic configured to store a table of received addresses, sequentially receive sensor data from each address in the table via a serial data bus, store the sensor data in a memory, receive an address from a processor via a high speed data bus, and provide stored sensor data from the memory to the processor via a parallel data bus.

  • Methods and apparatus related to packet generation and analysis
    Patent number: 8149730
    Abstract: In one embodiment, an apparatus includes a packet generation module that has a set of general purpose processing modules and is configured to define a test packet configured to emulate at least a portion of network traffic. The apparatus also includes a switch device configured to receive the test packet from the packet generation module. The switch device is configured to multi-cast the test packet via a set of ports of the switch device to a target entity based on a routing policy.
