  • Self-healing link sequence counts within a circular buffer
    Patent number: 7978705
    Abstract: Methods and apparatus that allow recovery in the event that sequence counts used on receive and transmit sides of a communications link become out of sync are provided. In response to receiving a packet with an expected sequence count from a receiving device, a transmitting device may adjust pointers into a transmit buffer allowing the transmitting device to begin transmitting packets with the sequence count expected by the receiving device.
    Type: Grant
    Filed: November 19, 2008
    Date of Patent: July 12, 2011
    Assignee: International Business Machines Corporation
    Inventors: Robert A. Shearer, Martha E. Voytovich, Craig A. Wigglesworth
  • Byte to byte alignment of multi-path data
    Patent number: 7546401
    Abstract: Methods and apparatus that may be utilized in an effort to ensure bytes of data sequentially received on multiple single-byte data paths with properly aligned when presented on a multi-byte interface are provided. A sufficient number of bytes received each channel may be stored (e.g., buffered) and examined to properly match data from each single-byte path. Once matched, the data may be output in a proper order on the multi-byte interface, for example, via some type of multiplexor arrangement.
