Abstract: In a communication network, a client has a plurality of network interfaces connecting it to a server able to deliver data streams on multicast groups. The client obtains a first request for subscription to a multicast group allowing to obtain a data stream. The client replaces the first subscription request with a plurality of second requests for subscription to a plurality of multicast subgroups able to supply data sub-streams which, once combined, allow to reconstruct the data stream. Each second subscription request is transmitted over a network interface with which the request was associated, so as to favour use of each available network interface. The client receives, over each network interface, a data sub-stream corresponding to the second subscription request transmitted over said network interface and reconstructs the data stream from the data sub-streams.

Abstract: A method for synchronising a first gateway of a LoRa network, intended to enable the first gateway to function according to the class B communication mode of the LoRaWAN protocol. The method relies on at least one reception of a synchronisation frame by the first gateway, each synchronisation frame having been transmitted by a second class B gateway in the LoRa network, equipped with synchronisation means and designated by a server. The first gateway uses an instant of reception of each synchronisation frame that it receives in order to synchronise beacon transmissions used in the implementation of the class B communication mode with beacon transmissions made by other class B gateways in the LoRa network.

Abstract: A gateway manages a first secure wireless local network and a second secure wireless local network. The gateway interconnects the second secure wireless local network and a wide-area network so that each device paired with the second secure wireless local network can access services offered by the wide-area network. The gateway detects an attempt at first pairing, with the first secure wireless local network, using first authentication data. The gateway checks with a provisioning server that the first pairing is performed by a device associated with the same user as the gateway, and checks that the first authentication data correspond to expected authentication data. In the case of a positive check, the gateway transmits, via the first secure wireless local network, second authentication data as well as a network identifier of the second secure wireless local network, with a view to pairing with the second secure wireless local network.
