Abstract: 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.

Abstract: A method is developed for dynamically configuring a network with numerous subnets, each subnet comprising at least one router node and said network comprising at least one subnet server. For enhancing the efficiency, the determination of a subnet master for configuring a subnet is carried out with two parallel processes: election of a subnet master among the router nodes of said subnet allocation to each router node of said subnet of a subnet identifier. Configuration of the subnet, achieved by the subnet master with its allocated subnet identifier, is refreshed regularly, in particular when detecting a change in the configuration of the network.
