Communication Method in a Communication Segment of a Network

摘要

A communication method is provided in a communication network, including a plurality of devices forming an ordered communication segment. At least one intermediate device of this segment is connected to at most two other devices called a previous device and a next device. The intermediate device receives data from the previous device and emits at least these data to the next device to propagate the data on the segment. A concentrator initializes transmission of a first frame of data through the segment to a terminal device ending the segment, which sends back a symbol initiating transmission of a second frame of data to the first concentrator through the segment. The method includes receiving a first symbol from the previous device, which triggers emitting a WAIT symbol to the previous device and emitting at least first symbol to the next device.

1. A communication method in a communication network comprising an ordered communication segment of devices, said segment comprising a first and a second terminal devices ending the segment and at least one intermediary device, wherein said intermediary device is connected to at most two other devices of the segment, called a previous device and a next device, receives data from the previous device and emits at least these data to the next device, allowing propagation of the data on the segment, the first terminal device being a concentrator initializing transmission of a first frame of data through the segment to the second terminal device, said second terminal device sending back a second frame of data downstream to the concentrator through the segment;
wherein the communication method comprises the following acts carried out by at least an intermediary device:
reception of a first symbol EOSF from the previous device of said intermediary device,emission of a WAIT symbol to the previous device of said intermediary device, said emission being triggered by reception of a first symbol, andemission of at least the first symbol EOSF to the next device of said intermediary device.
