Abstract: Methods/devices for managing messages broadcast in a local area network (LAN) include nodes allowing an extension of wireless communication coverage and stations. The nodes are connected together by a backhaul subnetwork, and at least one node sends at least one wireless network to which the stations are connected. The LAN includes a primary subnetwork and a secondary subnetwork. The primary subnetwork is a subnetwork to which the links of the backhaul network and the nodes belong. The secondary subnetwork is composed of at least one station and is isolated from the rest of the LAN by a virtual network. A node able to apply the filtering rules demands an analysis of the topology of the local network, determines, from the topology of the LAN, filtering rules to be applied, and applies the filtering rules determined to the broadcast packets including at least one item of information identifying the virtual network.

Abstract: A method for storing computer files in encrypted form, executed by a “key store” device and includes: establishing a list of pairs of keys wherein each of the pairs of keys is associated with a unique identifier authorized to access a computer file; receiving by an encryption key, then encrypting as many encrypted versions as there are public keys; recording an encrypted version of the computer file in a storage space accessible from the key store; a header or another part of the encrypted version of the computer file having the encrypted versions of the encryption key, each of the encrypted versions associated in the header with the identifier of the client, and in a list of files encrypted and stored under the control of the key store, as well as a pointer to an encrypted version of the file recorded in the file storage space.

Abstract: A method implemented by a first communication device is described, comprising receiving an identifier of a station connected to a first access point of a first set of access points broadcasting a first wireless network, determining a host access point of a second set of access points broadcasting a second network for connecting the station; transmitting to the second wireless network of the host access point a request to configure a third wireless network by the host access point, said configuration using the connection elements of the first wireless network; and moving the station to the given access point to enable the station to connect to the third network using the connection elements of the first wireless network. Also described is a method implemented by a second device, comprising a controller of the first network, as well as implementation devices.

Abstract: A methods/devices are provided for categorizing data streams passing between a station and an access point serving the station to determine whether the station can change access point serving it. The access point serving at least one station: identifies, from an identifier of the source and/or from the destination of the data, each data stream passing between the station and the access point, measures, for each data stream, the quantity of data passing between the station and the access point, calculates, for each data stream, a mean from the measurements for the stream, categorizes each data stream as an interruptible data stream if the mean of the data streams is lower than a first predetermined threshold, and determines that the station can be served by another access point if each stream passing between the station and the access point is categorized as an interruptible data stream.

Abstract: A method for managing a controller function of investigator equipment belonging to a backhaul network, the backhaul network comprising a plurality of items of equipment managing a unified wireless network. Each item of equipment the controller function of which is active fulfils a role of controller. The investigator equipment can activate and deactivate the controller function without requiring rebooting. The method comprises: recording age of investigator equipment corresponding to a time since which the equipment has been fulfilling the role of controller, broadcasting discovery request, determining that responding equipment is fulfilling role of controller according to information representing role of controller present in response from the responding equipment, when the controller function of the investigator equipment is active, obtaining the age of the responding equipment, and deactivating the controller function of the investigator equipment if the age of the investigator equipment is less than the age of the responding equipment.

Abstract: A method and a device for reconfiguring a first interconnection of a first node with a second node of a backhaul subnetwork in a local area network including a plurality of nodes, the first and second nodes being interconnected by a radio connection in a first frequency band. A controller node: selects a third node of the local area network, the third node being different from the first and second nodes, establishes a second interconnection between the first and third nodes by a radio connection in a second frequency band different from the first frequency band, deletes the first interconnection when the second interconnection is established.

Abstract: A method for pairing a terminal with an access point in a wireless communication network is described. The network comprises a plurality of access points that are centrally coordinated by a manager device. The method comprises the following steps executed by at least one access point: receiving a first message comprising information indicating that said terminal wishes to pair with said access point; sending a second message to said manager device, said second message comprising information indicating that said terminal wishes to pair with said access point; adding, in at least one beacon frame of said access point, information indicating that a pairing session is active, only on receipt of a message from said manager device notifying said access point to engage a pairing session with said terminal; and pairing said access point and said terminal.

Abstract: To pair a plurality of stations with a wireless access point, the wireless access point establishes a multiple pairing. The wireless access point includes, in broadcast beacon frames, a notification of triggering of multiple pairing, during a declaration period of predefined maximum duration. The wireless access point receives, during the declaration period, requests for participation in the multiple pairing coming from said stations. When the declaration period expires, the wireless access point implements individual pairings in turn with each of the stations in question.

Abstract: Determined is a topology of a communication network composed of a plurality of nodes connected or not respectively to at least one item of equipment, one of the nodes, referred to as the root node, being connected to an external network. A service class is determined for each node, from each node, information is obtained representing the quality of the link between the node and other nodes, for each link, parameters representing the quality of the link are calculated, the nodes are classified according to the service class thereof and according to the number of links making up the path that separates them from the root node, for each node and according to the classification, the possible paths connecting the node to the root node are determined, a score is calculated for each path determined, the path is selected for the node having the best score.
