  • Apparatus for high speed communication system
    Patent number: 6449274
    Abstract: Methods and devices useful in high-speed scalable switching systems include a memoryless switch fabric, per virtual channel queuing, digital phase aligners, randomized and complement connection modes, a mid-point negative acknowledge and output negative acknowledge scheme among other elements. A particular implementation of a routing table and switch element is described in part to illustrate the various techniques and devices of the invention.

  • Method and apparatus for detecting disabled physical devices and deleting undeliverable cells
    Patent number: 6226298
    Abstract: A system and method for flushing cells in an ATM network sets an interval timer during which it would be expected that an active physical output would indicate it could accept a cell. When an interval elapses, a physical output that has not indicated it is ready to accept a cell is marked as disabled and may remain so until the output is reset. Cells in an output queue to a disabled cell are flushed during periods when no higher priority cells are available to be sent.
