The slave station,sends out an isochronous data packet,using the token packet for isochronous data,According to the token packet for isochronous data,the slave stations,and,are designated as receiving stations using the ID for isochronous data “#,”, so that the slave stations,and,perform the above-mentioned operations, to receive the isochronous data packet,The sending station can thus transmit the same isochronous data to a plurality of receiving stations belonging to a broadcast group, so that it is possible to establish multicast communication (communication to a plurality of nodes).
