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.

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: There is provided a method for electing a master routing node of a given subnet of a network, comprising: determining (71) a first-type address associated with an interface of each node on the given subnet, and being the address given by a routing table of the next hop (router node or target node) on the path leading from the node to a target node; determining (72) a second-type address associated with the interface of each node on the given subnet, and being either the determined first-type address (if the latter is on the given subnet) or the address of the interface of the node on the given subnet (if the determined first-type address is on another subnet); sending (73) by each router node of the given subnet a message containing its determined second-type address; collecting (74) at the interface of each node on the given subnet the sent messages; selecting (75) for the interface of each node on the given subnet a third-type address among its determined second-type address and the second-type addresses contained in the collected messages, according to a selection rule known by all nodes of the subnet; electing (76) as master routing node of the given subnet the node having the selected third-type address.
