Method and apparatus for scheduling access to a CSMA communication medium United States Patent 05485147

05485147 is referenced by 37 patents and cites 19 patents.

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.
