ABSTRACT:
A network interface mechanism and method is provided that facilitates precise transmission time control in a computer network. The network interface mechanism and method uses feedback to provide monitoring and precise control of the transmission time. Specifically, a message detector is provided that monitors the network for transmissions from the network interface mechanism. The arrival time of messages is compared to the desired transmission time, and the transmission time of subsequent transmissions is adjusted accordingly. A transmission disable mechanism is used in the forward path to disable the transmission driver at the transmission cut off time as a means to prevent the transmission node from babbling the media. Thus, the network interface mechanism and method provide precise control of the transmission time, and thus can be used to eliminate collisions in the network. The network interface mechanism and method allows the application of Ethernet controller to have precise transmission timing control in a computer network.
