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.

Abstract: A securing method in a computing or communication network, the method making it possible to isolate a station connected to a wireless communication device of the network and identified as not complying with the security requirements defined for the network. The isolation of the connected station is performed automatically by a connection to a quarantine zone of the network, excluded from a so-called trusted zone. The device identified as not complying with the security requirements can, for example, access a wide-area network, such as the internet, but cannot access a secure local network.

Another object of the invention is a communication device configured to implement the method described.

Abstract: A method for correcting a packet of an Internet control message protocol (ICMP), during routing of a packet between a private and a public network having been processed by an application level gateway, includes reading a packet of an ICMP including a “need to fragment” message and the value of a maximum transmission unit defining the maximum size of data packets handled in a communication protocol used by a routing, calculating a value of a processing size by comparing a size of a packet not processed by the integrator of the application level gateway and a size of the same packet processed by the integrator, modifying the packet of an ICMP by overwriting the value of the maximum transmission unit with an actual maximum packet size value which depends on the value of the processing size, sending, to a transmitter having sent the non-processed packet, the packet of an ICMP.

Abstract: A wireless communication system includes a first access point managing a first wireless local area network and at least one second access point managing at least one respective wireless local area network. A CSMA/CA procedure is employed. The first access point is involved in a real-time sensitive transmission. Each access point implements an energy detection mechanism and a preamble detection mechanism in the context of the CSMA/CA procedure. The energy detection mechanism is implemented for accessing the primary channel and for accessing each secondary channel. The preamble detection mechanism is implemented for accessing the primary channel and optionally for accessing each secondary channel. A decision making unit instructs the first access point and each second access point to use the same primary communication channel. This improves the conditions under which the real-time sensitive transmission takes place.

Abstract: A method is directed to recovering a target file by an audio/video receiving equipment, the audio/video receiving equipment including at least two communication interfaces, including a first communication interface able to receive broadcast data and a second communication interface able to establish a bidirectional dialog with a server. The method makes possible to make data available simultaneously: in the “normal” direction, from the beginning to the end, on an IP interface via a file server (HTTP/FTP/etc.); in the “reverse” direction, from the end to the beginning, on a broadcast interface via a DSM-CC carousel, referred to as a dedicated channel. Thus the audio/video reception equipment can efficiently recover the data by simultaneously using two communication interfaces including at least one unidirectional interface.

Abstract: In order to reduce the large volume of data transmitted over a network, immersive videos are frequently represented by a multiple versions, each version being optimised in terms of quality for a point of view on the immersive video, the immersive video parts not representing the point of view for which the version was optimised being of lower quality. In this context, when a user using suitable viewing equipment views the immersive video, he must change version whenever he changes point of view. Each version is generally stored on a server relatively distant from the viewing equipment, which may give rise to latencies in the reception of a new version following a change of point of view. This latency time is reduced by allowing a node in the intermediate network between the server and the viewing equipment to transmit each version to the equipment in place of the server.

Abstract: A wireless communication system has an access point managing a first wireless local area network. To transmit the frame, the access point: obtains data to be transmitted in multicast mode; obtains data to be transmitted in unicast mode; and constructs a physical-layer header including: in a common signalling field, an identification of each channel resource intended to be used for making the frame transmission, whether this be for the data to be transmitted in unicast mode or in multicast mode; and, in each field in a series of specific signalling fields, information representing an association between a channel resource identifier used and a unique identifier of the destination concerned or group of destinations concerned. Thus each destination can determine each channel resource to listen to in order to receive the data that are addressed to it, whether this be in unicast mode or in multicast mode.

Abstract: A method is provided for managing an optimal transmission power of a Wi-Fi access point. Electronic devices are connected to the Wi-Fi access point, and the Wi-Fi access point is able to transmit with a variable transmission power. The method is executed by the Wi-Fi access point and includes the steps of determining a minimum value of a quality indicator associated with a connection of an electronic device to the Wi-Fi access point. A minimum transmission power value of the access point is determined making it possible to obtain, for the electronic device connected to the Wi-Fi access point, a value of the quality indicator associated with the connection thereof to the Wi-Fi access point higher than the minimum value. The optimal transmission power of the Wi-Fi access point is configured as being equal to the minimum transmission power determined.
