Claim 0:
1. A ring network communication system for transmitting data in a direction in a ring network in which a plurality of nodes are formed in a ring shape,
wherein each of the nodes comprises:
a data generation part, generating data to be transmitted to another node;
a data transmission part, having a data transmission block transmitting data generated by the data generation part of an own node as generated data and a data relay block transmitting data transmitted from the another node as relay data to be relayed;
an output switching part, switching data transmitted to the another node as the generated data transmitted by the data transmission block and the relay data relayed by the data relay block and outputting the data as transmitted data; and
a data reception part, receiving the data transmitted from the another node as received data,
wherein the nodes comprise:
a heteronomous node, operating in a heteronomous mode in which data generated by the data generation part of the own node is transmitted as the transmitted data only when the received data received by the data reception part comprises a transmission request; and
an autonomous node, operating in an autonomous mode in which the data generated by the data generation part of the own node is transmitted as the transmitted data regardless of reception of the received data comprising the transmission request.
