  • Method and apparatus for scheduling access to a CSMA communication medium
    Patent number: 5485147
    Abstract: A scheduling mechanism is provided for controlling when the arbitration circuit of a node sharing a CSMA communication medium is to start CSMA arbitration for access to the communication medium once the node has a message ready for transmission, the scheduling mechanism delaying the arbitration circuit from seeking access if total transmission activity on the communication medium exceeds a total use threshold value and transmission activity of the node exceeds a local use threshold value, and otherwise permitting the arbitration circuit to seek access to the communication medium by arbitration in accordance with a priority value assigned to the node.
    Type: Grant
    Filed: April 7, 1994
    Date of Patent: January 16, 1996
    Assignee: MTI Technology Corporation
    Inventors: David H. Jaffe, Hoke S. Johnson, III, Chris W. Eidler
