Abstract
A repeater that prevents a node involved in a collision from detecting that the collision occurred, and transmits the data packet received from that node to all other nodes connected to the repeater. The repeater accomplishes this by repeating the data packet received from that node during the collision, and discarding the data packets received from other nodes, thereby allowing a valid data packet to traverse the repeater and all communication medium segments attached thereto. The repeater maintains a count of the collisions and retransmission attempts experienced by each node since that node's last successful data packet transmission. The count is used to prioritize which of the nodes involved in a subsequent collision will be allowed to continue to transmit. Such prioritization reduces any disparity in the number of retransmission attempts experienced by each node, thereby reducing the likelihood of a node dropping a data packet as occurs when the maximum number of retransmission attempts allowed for such node is reached.
