Abstract: A transmission of a digital content to a user terminal is managed by a network comprising a service subnetwork adapted for providing the terminal with a service token, and a digital contents distribution subnetwork which includes a control part and a transmission part. The control part of the distribution subnetwork receives a request from the user terminal for a digital content, indicating a service token. Next, if the service token is recognized as valid, an address relating to the distribution subnetwork is determined and a session token associated with said address is generated. A message indicating said address and the session token associated with said address is then transmitted to the user terminal.

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 of transmitting a data stream previously coded according to an adaptable coding between a first terminal and a second terminal through the intermediary of a session established according to an HTTP-based transport protocol is disclosed. In one aspect, collection is by the first terminal of a set of context information relating to the session, to the first terminal and to the second terminal. Then, formation is of an adaptation scheme as a function of the set of context information. Next, adaptation is of the data stream by the first terminal as a function of the adaptation scheme. Lastly, transmission is of the adapted data stream by the first terminal to the second terminal.

A message indicating said address and the session token associated with said address is then transmitted to the user terminal.

Abstract: A mediation unit (2, 3, 4, 5) in a telecommunications network for mediating between an application service provider (1) and a plurality of service providers (6), said unit (2, 3, 4, 5) comprising recovery means (2, 3) for recovering data concerning users from various service providers (6) and acquiring indications qualifying a user and qualifying one or types of data required on that user, such indications being issued by the application service provider (1), which mediation unit is characterized in that it comprises means (4, 5) for identifying a selection of service providers (6) containing the type of data required by the user, the recovery means (2, 3) further taking account of this selection so as to interrogate only service providers (6) selected in this way.

Abstract: A method of creating a tunnel for transporting at least one data flow in a label-switched telecommunication network, the telecommunication network comprising at least one ingress edge router, a server able to define tunnels, called static tunnels, in the telecommunication network based on traffic forecasts in the telecommunication network. The method includes the steps, performed by an ingress edge router receiving an admission request from a client to transfer a data flow in the telecommunication network, of determining whether a static tunnel defined by the server in the telecommunication network is able to transport the data flow, creating a tunnel, called dynamic tunnel, able to transport the data flow in the telecommunication network if no static tunnel defined by the server is able to transport the data flow.

Abstract: The invention relates to a method of managing a plurality of multimedia sessions involving user terminals connected to an access point of an IP network including at least one collection node when at least one audiovisual first session is in progress during which a first user terminal receives an audiovisual content encoded in the form of a plurality of SVC audiovisual streams via a link between said access point and said at least one collection node. The method of the invention receives a change request relating to a second session that is one of said plurality of sessions, recovers information relating to a context of said plurality of sessions, evaluates a new distribution of resources between said first session in progress and the second session, decides to accept or reject the change request as a function of the result of said evaluation and sends a message containing its decision.

Abstract: The invention concerns a method and a device for controlling admission to a guaranteed quality of service in a MPLS network (150), the MPLS network consisting of at least one input peripheral router (100) and one output peripheral router (120), the data flows being transported in the MPLS network through tunnels.

Abstract: The invention relates to supervising the distribution of contents in a telecommunications network (R). A content contains data specific to a given acquisition of rights to the content, written in the form of a digital watermark (WM). During its transfer across an access network (RA), the content is analyzed to detect the presence of a digital watermark. The data specific to the acquisition is then extracted from the watermark and sent with data characteristic of the transfer in progress to central supervisory equipment (300) of the telecommunications network (R) in order to determine if the transfer in progress is legitimate.

Abstract: A mediation unit (2, 3, 4, 5) in a telecommunications network for mediating between an application service provider (1) and a plurality of service providers (6), said unit (2, 3, 4, 5) comprising recovery means (2, 3) for recovering data concerning users from various service providers (6) and acquiring indications qualifying a user and qualifying one or types of data required on that user, such indications being issued by the application service provider (1), which mediation unit is characterized in that it comprises means (4, 5) for identifying a selection of service providers (6) containing the type of data required by the user, the recovery means (2, 3) further taking account of this selection so as to interrogate only service providers (6) selected in this way.

Abstract: A mediation unit (2) for mediating between application service providers (1) and resource providers (3) in a telecommunications network, which mediation unit (2) comprises means for receiving a resource allocation request (a) from the service provider (1) and requesting the corresponding resource from the resource provider (3) and is characterized in that it comprises means for receiving and taking into account an acknowledgement message (c?, d?, e?, f?, g?, h?, i?, j?) from the resource provider (3) to the effect that the resource necessary for supporting the quality of service has been implemented and means for receiving resource allocation requests from an application service provider (1) and requesting corresponding resources from resource providers (3) and receives and takes into account acknowledgement messages (c?, d?, e?, f?, g?, h?, i?, j?) coming from each resource provider and sends a notification to the application service provider (1) to the effect that all of the requested resources have been im
