Abstract: A scalable and cost-effective solution for implementing a cache in a data processing environment. A sliding window comprises a number of past time slots. For each time slot, a number of request for a data item is counted. A mean request rate for the data item is computed over the sliding window. If the mean request rate is superior to a threshold, the data item is added to cache, or the data item is removed from cache otherwise.

Abstract: The invention relates to a method and a device for converting a data stream transporting content into a file on a server, the content including timestamps for its playback, the timestamps indicating the time elapsed since the start of said content, the method being wherein it includes steps for receiving, from a broadcast channel, streaming content, calculating at least one piece of temporal playback information from at least one of the timestamps and a reference clock, the reference clock being the time reference for a local area network, saving the content to a file on a server, the server file being accessible by a playback terminal connected to the local area network, and saving a piece of temporal playback information to a server file or to a description file associated with the server file.

Abstract: The proliferation of digital devices has favored an explosion of the amount of image data stored by a user, and it is quite easy for a user to end up with many image duplicates in the user's image library. Prior art solutions can still be optimized with regard to detection of duplicate images in data storage. Notably, user intervention is to be restricted. A correspondence is detected between a first and a second image of the collection, and metadata is associated with the second image that characterizes the detected correspondence. Then, a predetermined image collection management action is applied to second images according to the associated metadata.

Abstract: The invention proposes a method and device for adding redundancy data in a distributed data storage system. Among others, the invention allows to keep impact on network resources low through the use of coordinated regenerating codes according to the invention.

Abstract: Method for transmission of images comprising: a reception of a source digital image comprising padding lines and data lines, the data lines comprising ancillary data and video data. In order to optimise the use of a transmission channel, the method also comprises: a filtering of padding lines to form sets of data comprising ancillary data and video data; a cutting of the sets into fragments of a maximum fragment length that is a function of a maximum transport packet length; an insertion of at least one image number in each of the fragments, each of the ancillary data and video data being associated with this number; an insertion of fragments into transport packets; and a transmission of the transport packets according to an internet protocol. The invention also relates to a corresponding method for reception.

In order to optimize the configuration of the first wireless network, the method comprises a step of configuring at least one parameter of the at least one access point of the first wireless network on the basis of at least a portion of the linking balance of a second wireless network including at least two nodes, the nodes being positioned in a predetermined physical space.

Abstract: Within the framework of a wireless local area network, the reliability of the transporting of the multicast streams is not enhanced by an acknowledgement of receipt mechanism. To improve this reliability the invention proposes a method of transporting packets transmitted in multicast mode by a device for connection between a first network and a second network, the multicast packets originating from the second network destined for clients of the first network, characterized in that it comprises a step of reception of multicast packets and the despatching according to a unicast transmission mode of at least certain packets transmitted in multicast mode to at least one of the clients of the first network that are subscribers to the transmission group.

Abstract: Method for linking a first and a second communication bus through a wireless link, comprising a first portal connected to the first bus and a second portal connected to the second bus, said first and second portal communicating over a wireless connection. The method comprises the steps of: associating the two portals to the wireless network; exchanging, between the two portals of self identification packets of nodes connected to their respective local busses, including the self identification packets of the portals themselves; generating a reset on each bus; carrying out a self identification procedure on each bus, where each portal generates self identification packets for itself and for nodes of the respective remote bus, using the self identification packets received following the association step.

Abstract: The invention concerns method to distinguish between streams received by an access point from a distribution network and transmitted to stations and a way to give better priority to some of them towards others. In a system where streams are transmitted with a level of priority corresponding to there type, it adds a selection criterion to determine priority between streams of the same type. The invention also concerns an access point implementing the method.

Abstract: The invention concerns a method for transmitting packets in a network comprising at least a first sub-network and a second sub-network connected through a transparent communication link, said link comprising at least a first interface device connected to the first sub-network and a second interface device connected to the second sub-network. The method comprises the steps of: attributing a first set of addresses to the interface devices on the communication link; attributing a second set of addresses to nodes connected to the sub-networks, the attribution of the second set being done independently from the attribution of the first set; checking whether there appears a conflict between an address of the first set and an address of the second set, and in the affirmative: changing the conflicting address of the first set to a non conflicting address. The invention also concerns a device for implementing the method as well as a method for detecting and transmitting packets to be transmitted over the link.

Abstract: The present invention concerns a network device and a method at the network device.
