This method consists i), in determining for some at least of the N nodes (S1-S4) at least one resource reservation plan Pik defined by a plan identifier associated with a stream identifier and at least two ports, and ii) in memorizing for each of the N nodes (S1-S4) the various plans Pik relating to them.

Abstract: A method is intended for scheduling reservations of resources in a packet-switched communication network comprising end-nodes (H1-H3) and core network switches (S1-S2). This method comprises the steps of: including a time information to each request, issued by an end-node (H1) and forwarded by at least one core network switch (S1), and requesting a resource reservation for receiving a stream defined by specifications at a time which is represented by this time information, and storing the time information, which is included into each forwarded end-node request in correspondence with the associated stream specifications, into at least one related database managed by a core network switch (S1) which participates to the request forwarding.

Abstract: The inventions concerns a network data storage system comprising a storage unit, at least one network client and an intermediate network switch. The storage unit contains at least two data storage servers each comprises a local storage component containing digital file segments of at least one digital file and is adapted to execute a local digital file management method organizing the physical location of the digital file segments. Each data storage server is adapted to communicate with the other data storage servers and to execute a distributed digital file management method. The distributed digital file management method maintains a record of operations and communicates internally with the other data storage servers to obtain information concerning the digital file segments contained on the other data storage servers and an overview of all information concerning all digital files stored on the storage unit.

Abstract: The invention concerns a communication device including several external data sources, at least a local area network connecting peripherals, means enabling to establish connections between the local area network and the external data sources, means for controlling the incoming data from the external sources and for sending them to the local area network in order to reduce the bandwidth occupation on the local area network. The device also includes means for updating signalization tables included in the incoming data and means for inserting the modified signalization tables in the transport stream sent to the local area network. It is applicable to IEEE 1394 networks.

Abstract: A device is coupled to a first network and a second network and comprises a first storage element and a second storage element. The device stores data packets originating from the first network in the first storage element and stores data packets destined for the second network in the second storage element. In particular, the device slaves the writing of a data packet intended for the second network into the second storage element to the reading of the data packet from the first storage element so that the transfer time inside the device is constant for all the data packets.

Abstract: The invention concerns a method comprising a step which consists in comparing a label to a value counted from a transfer clock to define the transfer time on the bus of a packet read on a recording medium. The invention is characterized in that for implementing a special mode or trick mode, it further comprises the following steps: calculating a difference between two consecutive packets based on the values of recorded labels; calculating an offset value based on said difference and parameters received on the bus defining the special mode; adding said offset value to the label value of the transmitted packet to obtain a new label value defining the transfer time on the bus of the following packet to be transmitted. The invention is applicable to the storage of MPEG data.
