摘要： A network re-encoding device is intended for re-encoding encoded symbols to be transmitted to at least one communication equipment connected to a network. This network re-encoding device comprises a re-encoding means arranged for re-encoding output nodes, defined by LT code symbols representative of encoded symbols and representative respectively of the results of XOR Boolean operation between input nodes defining decoded symbols whose values have to be discovered and to which they are linked into a Tanner graph, by combining chosen input node and/or output node having known values, in order to produce new LT code symbols defining generated output nodes ready to be transmitted.

摘要： A device and a method for online storage, device and method for searching for similar content, a device and a method of transmission and a device and a method. Encrypted data is saved at a provider of online services. With the encrypted data, encrypted hashing data is saved with a public key and the content to save is encrypted with the encrypted hash. This advantageously enables data duplication at the online service provider to be prevented while preserving the private life of the users of the service. In order to search for content similar to reference multimedia data, fingerprints are also saved at the service provider. In order to limit the number of false positives returned, the fingerprint can further contain a search fingerprint, an encrypted selection fingerprint.

摘要： A method dedicated to the management of data transmission in peer to peer mode between peers (P1-P4) that can connect to a communication network (R), each transmission being carried out by a peer (P1), following the reception of a request from another peer (P2), according to a selected reciprocity mechanism. This method consists, when a peer (P2) wants to receive from another peer (P1) N blocks of data according to a first priority level Xk selected in a set of at least two different priority levels, in assigning to this peer (P2) an exchange value equivalent to a number M of blocks of data to be transmitted to at least one other peer (P1) according to a second priority level Xk′ selected in this set, M being equal to N*mkk′, where mkk′ is a predetermined value function of the first Xk and second Xk′ selected priority levels.

摘要： A method is intended for disseminating content data in a peer-to-peer mode between peers connected to at least one communication network. This method comprises the steps of: i) making peers exchange neighboring information between them to build a bipartite peer overlay comprising a first group, comprising peers having a complete content to be disseminated, and a second group, comprising peers having not this content or only a part of it and having links therebetween, ii) disseminating the data defining the content (and preferably encoded with erasure correcting codes) from peers of the first group to first peers of the second group according to the bipartite peer overlay, iii) disseminating the data received by the first peers to other peers of the second group according to the bipartite peer overlay, and iv) updating the bipartite peer overlay when a peer of the second group has fully completed the content.

摘要： The present invention relates to a method for uploading in an on-line storage system a file from a user client device through a gateway connected to the client device through a local area network and to the on-line storage system through a wide area network. The on-line storage system comprises a storage server coupled to a target storage device in which the file is to be stored.A gateway receives from the user client device an uploaded file.If the file is not present in the target storage device, the gateway uploads the file to the target storage device, and if the file is present in the target storage device, the gateway creates a link to the file stored in the target storage device.

摘要： A replication set of k storage devices is defined, that stores a particular data item. Each device in the replication set has an associated timer for which a timeout value for disconnection is determined based on individual downtime data distribution of the device. A new device for storing the data item is added to the replication set when the timer expires for a device in the replication set, and if the number of devices in the replication set that are still connected is below a predetermined threshold. Timeout values are adapted according to a factor of criticalness determined for the replication set, resulting in a more reactive, or on the contrary, a less reactive replacement of devices in the replication set. The factor of criticalness is determined according to a difference between the connected devices in the replication set and the predetermined number k.
