Abstract: A method for preparing usage data for a relay implemented in a computer network is disclosed. In one aspect, the network comprises at least one source device, one destination device, and at least one relay constituting a circuit to set up a communication between the source device and the destination device. The source device first of all retrieves the identifiers of the relays constituting the circuit and sends a proof of use (PoU) frame addressed to the destination device, each relay of the circuit adding to the PoU frame, at the time of passage, a signature made from a challenge and a key proper to the relay.

Abstract: A method, a device and a program are provided for processing data. The method is implemented within an intermediary module. The data is transmitted between a customer module and a server module connected through a communications network. The method includes: receiving, from one among the customer and server modules, an intermediation request identifying an operation of intermediation to be performed relative to a stream of encrypted data exchanged between the customer module and the server module; and processing relative to said encrypted data as a function of said operation of intermediation.

Abstract: One embodiment relates to a method for obtaining, in a communication network, a routing policy indicating rules for routing requests emitted by a software module running on a client device. The method comprises sending, by the client device, a connection request to an authentication server of the communication network in order to attach the client device to the communications network- and receiving, by the client device, a connection context response from the authentication server. The context comprises an identifier of a system for managing routing rules. The software module obtains the routing policy in accordance with at least one first rule for routing to a proxy system certified by the operator of the communications network obtained by means of the identifier.

Abstract: The method performed by a receiver entity in a hierarchical network, the entity having knowledge of the hierarchical levels of nodes of the network is disclosed. In one aspect, the method comprises, on reception of a request to store data as sent by a sender unit: a step of selecting at least one storage entity for storing the data, the selection step taking account at least of the hierarchical level of the storage entity in the network; and a step of sending information to the sender unit enabling it to obtain the identifier of the data storage entity.

Abstract: A method is provided for authentication by token for accessing a service from a terminal. The method includes, on receipt of a service access authorization request including at least one unique identifier of the terminal, steps of determining a network access context of the terminal; checking validity of the service access rights, including at least checking an access right associated with the network access context of the terminal; and, if the access rights are valid, generating a valid authentication token on the basis of the unique identifier of the terminal and the network access context, and transmitting the token to the terminal.

Abstract: The invention relates to a method for managing contents in a contents distribution network (2) comprising physical resources (30, 40) able to host at least one virtualized delivery resource (31, 32, 41), the method comprising the following steps implemented by a management entity for a contents delivery service (10): obtaining (E2) of a listening parameter in relation to a content at the level of at least one of said physical resources able to host a virtualized delivery resource storing at least one fragment (61-64, 71) of said content; issuing (E4) of a command for adaptation of at least one virtualized delivery resource hosted by one of said physical resources as a function of said listening parameter.

Abstract: The invention concerns a method for admission control of connections made up of one or several flows to a shared wireless medium. It applies criteria for each new connection to determine whether resources can be provided for this connection. The criteria include the steps of: calculating a number (R) of retransmissions of frames which are needed, depending on: a target application PDU error rate (?i); a data link layer mean error rate (BER); and a maximum size (L) of the transmitted frames; calculating the achievable quality of service parameters (T?i) based on the calculated number (R) of retransmissions with the target application PDU error rate (?i), and determining if resources can be provided for the connection depending on the achievable quality of service parameter (T?i).
