Abstract
A communication frame has a counter value which is updated each time the communication frame passes through a node, and a source address. Therefore, upon receiving the communication frame, the node references a source address to check to see if the communication frame was generated by the node, that is, if the communication frame is a returned frame. In addition, even when the node finds that the received communication frame is not the communication frame generated by this node, the node checks counter value information in the communication frame to check to see if the communication frame has already circulated around the network, that is, if the communication frame is abnormal. Furthermore, because the counter value information is provided in each communication frame, the present invention is compatible with a system where a plurality of communication frames are on a network at the same time.
