Abstract:
The method of asynchronous delivery of digital data according to the invention is implemented in at least one server system and at least one client system connected via a network.According to the method, at the time of a request for data coming from a client system, an item of context information (CINF) representing a first state of the client system on sending out the request is associated with the latter.On delivering to the client system a response, the response incorporates the context information (CINF).The client system is adapted to put itself in a second state analogous to the first state mentioned above, in accordance with the context information (CINF, CUID).The method according to the invention provides context management enabling the user to associate the responses received with requests sometimes made well beforehand.
Abstract:
A method is proposed for managing a transmission of data streams on a transport channel of a tunnel, the transmission of each stream being performed on the transport channel according to a transport protocol scheduled by packets and with acknowledgment, the tunnel being implemented between a first and a second tunnel end-point connected respectively to a first and a second sub-network, each stream being transmitted from a sender device to a receiver device, one device among the sender device and the receiver device being connected to the first sub-network and the other to the second sub-network. The method is performed by the first tunnel end-point and comprises the following steps: detecting a loss of packet on the transport channel of the tunnel; identifying at least one stream having at least one packet blocked on the transport channel of the tunnel by the loss; for at least one identified stream, generating and transmitting at least one acknowledgment to the sender device that has transmitted, on the tunnel, a packet blocked by said loss.
Abstract:
In order to share digital data in a peer to peer communication network, a partial version of the data is firstly transmitted to destination stations, and: a collection of data is created in which an identifier is associated with each data item and to each data identifier there is allocated a label indicating whether the complete version of the data item is available on the network; the existence of the collection is notified to at least one destination station; and, on the reception of information on availability on the network of the complete versions of the data of the collection: the collection is updated; and the updating of the shared collection is notified to the destination station or stations.
