A method for synchronizing a plurality of servers of a communication network, which are capable of exchanging time-stamped data using a time reference. The method is implemented by a primary server of the plurality and includes: transmitting to the other servers, called secondary servers, an initialization message containing an identifier of the primary server, a data item resulting from execution of an algorithm for selecting the primary server from the plurality of servers, and a piece of transmission time information on the initialization message; receiving from at least one secondary server a message acknowledging the transmitted initialization message; and validating a synchronization challenge comprising a difference between a recorded transmission time reference and the piece of transmission time information on the initialization message. The piece of transmission time information replaces the recorded time reference for the time-stamping of the data exchanged between the servers once the validation is complete.

Method for synchronizing a plurality of communication servers, and corresponding computer devices and programs

A method for capturing a packet from an encrypted session established between a terminal unit and a data server. The packet includes a datum for determining a security key used for the encryption of the packet. The method is implemented by a device routing the packet between the terminal unit and the data server and includes: analysis of a plurality of packets transmitted by the terminal unit and destined for the server; identification of a cooperation packet from among the plurality of analyzed packets, the cooperation packet including the determining datum corresponding to a security key used for the encryption of packets transmitted by the terminal unit to the data server prior to the terminal unit sending the cooperation packet; and decryption of the received cooperation packet using a security key corresponding to the determining datum from the identified cooperation packet.

Method for capturing a packet from an encrypted session

A method is described for processing a data transport service in a virtual data space deployed on a communications infrastructure, the virtual data space comprising a plurality of sites each comprising a communication server, also referred to as a connector, capable of hosting a data item or an application for processing the data. The method is implemented by an optimisation entity capable of communicating with the connector and comprises receiving a request for deploying the data transport service from a data management agent; obtaining a connectivity parameter with respect to the communication infrastructure of a connector of a site among the plurality of servers, the connector contributing to the data transport service of the received request; and determining at least one data path in the virtual data space, the at least one path comprising an ordered series of connectors selected according to the obtained connectivity parameter.

Method for processing a data transport service

A method of activating at least one processing entity from among a plurality of entities situated on the path of a data of a session between a terminal of a user and a server of a services provider. The terminal and the server are attached to a communications network. In the method, the terminal: sends to the server an identification message to receive identifiers of entities of the plurality, which are added to the message by the entities; receive from the server an acknowledgement message including the identifiers included in the identification message; select at least one identifier from among those received from the server; and send to the server a message relating to the activation of entities from among the plurality.

Method of activating processes applied to a data session

The invention relates to a method for managing at least one communication pathway between a first router () and a second router (), being characterised in that it comprises the following steps: establishing a session () between a terminal () connected to the first router () and a remote piece of equipment () connected to the second router (); analysing at least one characteristic of the session () in order to determine whether said session () is collaborative and if this is the case: receiving at least one signalling message containing at least one piece of information relating to a characteristic of said session (); determining parameters of the connection between said routers () depending on the at least one obtained piece of information; modifying the at least one communication pathway () between said routers (), depending on the determined connection parameters; and transmitting the data of said session () over said modified communication pathway ().

Method for dynamically managing communication pathways between routers depending on application requirement

A method for recommending a communication stack formed of communication protocols, relating to a data session between a terminal and a first server to provide content in a network including a second server responsible for providing the content by delegation from the first server, the first server having detected incompatibility of the stack used by the terminal and having transmitted a redirection message including information relating to a recommendation of the stack to be used to obtain the content to the terminal. In the method, the second server receives, from the terminal, an acquisition request message; selects a stack to be recommended based on data relating to the communication network or to the received acquisition request message; transmits, to the terminal, a recommendation message including the recommended stack; and receives a message transmitted by the terminal, using the recommended stack, relating to the acquisition of the item of content.

Method for recommending a communication stack

A method and a device are provided for managing, in a receiving entity, data packets received from a transport layer connection established with a transmitting entity. The connection includes at least one stream in connected mode and at least one stream in non-connected mode. The management method includes transmitting, by the receiving entity, a so-called return message, relating to at least one data packet from one of the two streams in connected mode or in non-connected mode of the connection, the return message being transmitted to the transmitting entity on the other stream of the connection.

Method and device for managing packets in a multi-stream and multi-protocol connection

A method for controlling, in a communications network, recommendation messages exchanged during a session between a first endpoint, referred to as a source entity, and a second endpoint, referred to as a receiving entity. The messages are exchanged via a tube grouping data packets of a communication protocol with no guarantee of the delivery of the data packets. The method includes: obtaining recommendations contained in the recommendation messages via a control entity located on a network path of the tube, the control entity being authorized by an operator of the communications network; calculating a new recommendation message, on the basis of the recommendations obtained and of at least one information item relating to conditions of the network provided by the control entity; and sending the new recommendation message to at least one network entity located at one end of the tube.

Method for controlling recommendation messages in a communications network

A method is provided for managing notifications between a user agent installed in a mobile terminal and a web server. The method includes the following acts, carried out by an intermediate piece of equipment: receiving a notification message from the mobile terminal in accordance with a first protocol designed for transmission over a signaling channel, the notification message including notification data from the user agent; generating a notification message in accordance with a second protocol designed for transmission over the Internet network, in which the notification data is inserted; and transmitting to the web server, of the notification message in accordance with the second protocol. Also provided are an intermediate piece of equipment implementing these acts, as well as a method for sending a notification message and a mobile terminal implementing such a sending method.
