Communication method in a communication segment of a network

摘要

The invention concerns a communication method in a communication network comprising a plurality of devices forming an ordered communication segment, at least one device of this segment being connected to at most two other devices called previous device and next device, at least one device receiving data from the previous device and emitting at least these data to the next device allowing the propagation of the data on the segment. A first concentrator of the segment initializes the transmission of a first frame of data through the segment to a terminal device ending the segment, said terminal device sends back a symbol initiating the transmission of a second frame of data to the first concentrator through the segment. The communication method comprises the following steps carried out by at least a determined device : receiving a first symbol (EOSF) from the previous device of the determined device, this receiving step triggering a step of emitting a WAIT symbol to the previous device and a step of emitting of at least first symbol (EOSF) to the next device of the determined device.
