Abstract
A method of multi-address communication in a loop network formed by connecting a plurality of nodes each provided with a data processor to one another through a transmission line in which, in order for a transmitting node having transmitted a multicast information frame to be able to confirm the delivery of the multicast information frame, the transmitting node transmits a multicast response frame for the delivery of confirmation of the multicast information frame, immediately after the transmission of the multicast information frame, and receiving nodes present information for indicating the reception of the multicast information frame at the address part of the multicast response frame, in the order of node arrangement in the loop network in the direction from the transmitting node toward the downstream thereof, to check the information by each of the receiving nodes and the transmitting node.
