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 device for interconnecting a first communication network and a second communication network comprises a plurality of components functioning in an active mode or a standby mode. Said interconnection device performs the following steps: changing to active mode (401) the plurality of components under the control of a secondary processor, the secondary processor being a component of the interconnection device continuously in active mode and controlling changes to active mode following the change to active mode, sending (405) an interrogation request to a service-management server (110) connected to the first communication network in order to check the existence of service demands, receiving (407) a response to the interrogation request; and changing the plurality of components to standby mode (427) at an instant dependent on the response received.

Abstract: A method is provided for installing a new node in a wireless home network having a client network and includes a node able to form a mesh network. A connection of a new node to the client network supplied by the home network node is detected, and an identifier of a client device that is connected to the client network is received. If the client device is known to the home network: the new node is notified that the client device that is connected to the client network must be disconnected from the client network; a connection of the client device to the client network supplied by the node of the home network is detected; and identifiers of the mesh network are transferred to the new node if the connection of the disconnected client device to the client network supplied by the node of the domestic network is detected.

Abstract: In a secure end-to-end transmission of data between a first device and a second device via a message broker, the following are performed: a sharing of an entropy pool between the first device and the second device via the message broker, by means of signalling messages, any payload of which is encrypted asymmetrically and which comprise a message signature; and a transmission of subsequent messages between the first device and the second device via the message broker, each said subsequent message comprising a header and a payload, the header comprising an identifier of an authentication key obtained from the shared entropy pool and an identifier of a symmetrical encryption key obtained from the shared entropy pool, the payload being encrypted symmetrically by means of the symmetrical encryption key, and the whole formed by the header and the payload being authenticated by means of a message authentication code obtained by means of the authentication key and inserted in the header. Thus, the subsequent messages benefit from the non-repudiation afforded by the way in which the entropy pool was previously shared.

Abstract: The invention relates to managing requests for subscription to multicast transmissions in a communication network, at least two branches thereof being interconnected by an interconnection device comprising a module consuming such subscription requests preventing the propagation of said requests from one branch to another. At least one of said branches comprising at least one bridge device, the interconnection device comprising a subscription announcement module, said subscription announcement module performs the following step: upon reception (404; 412) via a branch of a first request for subscription to a multicast transmission, transmitting (407; 415) a second request for subscription to said multicast transmission at least via the branch via which said first subscription request was received.

Abstract: The invention relates particularly to a method for a wireless communication network, the method allowing the bonding of a plurality of radio connections between a client electronic device and a master electronic device, the method having the steps of receiving, coming from a client electronic device, a message having a request to establish a new connection, the message having an identifier of the client electronic device and authentication information, determining whether a second connection is already established between the master electronic device and the client electronic device, and, if such is the case, then sending, via the connection already established, a message having a request to verify the establishment request received, the message having the authentication information received, receiving a message having information validating the request to establish the new connection, and establishing the new connection between the client electronic device and the master electronic device.

Abstract: A method for creating a supplementary subflow as a supplement to a subflow existing in a multipath network connection using a transport protocol suited to a multipath communication mode. The multipath network connection is implemented in a network comprising a source using said multipath network connection for communicating with a receiver via an intermediate network component. Following an opening of an intermediate communication path between the intermediate network component and the receiver, said intermediate network component implements the following steps: obtaining a packet intended for the source; creating a header representing a request to create said supplementary data packet subflow, the supplementary data packet subflow being intended to use the intermediate communication link; inserting said header in said packet; and transmitting said packet to the source so as to cause the initiation, by the source, of a procedure for creating said supplementary data packet subflow.

Abstract: The present invention relates to the field of methods of communication between software modules and more particularly software buses. There is described a software bus which allows communication between software modules. This communication occurs within a machine and between machines and operates interchangeably for the software module whether one is dealing with a process, a thread or a simple task. The communication relies on mechanisms adapted to the multitask level at which the sender and receiver software modules operate. It is based on a hierarchical architecture, phases of discovery and of recording of the various software modules having to communicate via the bus.
