Abstract
A method of automatically determining an order of transmitting a packet for a local area network using the CSMA/CD protocol. In transmitting a packet from an arbitrary station I on the local area network while another station P is transmitting a packet, the packet of the station I is automatically classified into three cases. The first, denoted by letter [A]a packet whose transmission process is not completed, is at the station I before a requested time if transmission starts after the transmission packet of the other station P is transmitted completely. The second, denoted by letter [B], is a packet whose transmission process does not completed at the station I before a requested time if transmission of another station Q is permitted after the transmission packet of the other station P is transmitted completely. The third, denoted by letter [C], is a packet which does not belong to cases [A] and [B]. A transmission process of the packet is performed in accordance with the classification result.
