发明名称 METHOD FOR DETERMINING DATA TRANSMISSION STATE IN DATA COMMUNICATION SYSTEM
摘要 <p>A data transmission state deciding method in a communication system and a communication device are provided to enable an upstream node to notify a downstream node of a data reception state of the upstream node, while the downstream node can compare the data reception state with a data reception state of the downstream node, thereby deciding on the data transmission state. A communication device(10) of an upstream side notifies a communication device(20) of a downstream side of NEXP(0) which is a data reception state. The communication device of the downstream side compares the notified NEXP(0) with NEXP(1) which is a data reception state of the communication device of the downstream side. It is specified whether each of data is normally transmitted by comparing reception states(arrival/non arrival) of each of the data, or a damaged link is specified if the link is damaged.</p>
