A method intended to aid in the reservation of resources within a packet-switched communication network (CR) comprising a number N of relaying nodes (S-S). This method consists i), in determining for some at least of the N nodes (S-S) 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 (S-S) the various plans Pik relating to them.

Method for aiding the reservation of resources for a packet-switched network, and associated management device and aid device

A method is intended for scheduling reservations of resources in a packet-switched communication network comprising end-nodes (H-H) and core network switches (S-S). This method comprises the steps of:

Time synchronized resource reservation over packet switched networks

A method for restoring a service reservation booking system in a network after a failure, that comprises a first step of invalidating at least a portion of the bookings which cannot be seen anymore by the service booking system due to the failure, a second step of recalculating the bookings which cannot be seen anymore by the service booking system by validating the bookings which are valid in the network topology after the failure and by cancelling the bookings which are invalid in the network topology after the failure. Advantageously, the method of the present invention further includes a third step during which the nodes of the network disappear from the service booking system. The present invention also includes to a service booking system in a network.

Method for aiding the reservation of resources for a packet switched network, and associated management device and aid device

The described technology relates to cryptographic equipment which includes an input interface, a red module, a cryptographic module, a black module, and an output interface. The cryptographic module includes a cryptographic unit, which interacts with the red module and with the black module, and a management device, which interacts with the input interface and with either the red module or the black module, but not with both simultaneously. The cryptographic unit and the management device are physically and logically separate from one another and independent, and have an identical protection mechanism capable of protecting the integrity of the management device so as to detect any attempt at tampering.

Cryptographic equipment implementing red/black communication modes

A method and apparatus for scheduling reservations of resources in a packet-switched communication network including end-nodes and core network switches are described including a time information to each request, issued by an end-node and forwarded by at least one core network switch, and requesting a resource reservation for receiving a stream defined by specifications at a time which is represented by the time information, the reservation scheduling being handled at a data link layer of an Open Systems Interconnection (OSI) model and storing the time information, included into each forwarded end-node request in correspondence with associated stream specifications, into at least one related database managed by a core network switch participating in the request forwarding.

Storage device for stream data such as digital video and for non-stream data such as computer files, comprising a single file system which features a first type of storage unit for storing audio and/or video streams and a second type of storage unit for storing non-stream data, wherein the size of the first storage unit is a multiple of the size of the second storage unit, said device further comprising means for allocating a unit of the first type either for stream storage or to split a unit of the first type into a plurality of units of the second type, for storage of non-stream data. The invention also concerns a method for storing stream data or non-stream data. Applicable in digital television systems.

Method and device for storing stream data such as digital video and non-stream data

A method intended to aid in the reservation of resources within a packet-switched communication network comprising a number N of relaying nodes. This method consists i), in determining for some at least of the N nodes 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 the various plans Pik relating to them.

Method of aiding the reservation of resources for a packet switching network, and associated management device and aid device

The present invention relates to a communication device comprising switching means in a packet switched networks, preferably in professional video production and broadcast environments. The present invention more particularly concerns a communication device in a packet-switched communication network, comprising means for: The present invention also concerns a method of switching in a packet-switched communication network comprising a plurality of sources of data, a communication device and at least one destination device.

Virtual multimedia matrix over packet switched network

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.

Network data storage system

The present invention relates to the domain of video equipment. More specifically, it concerns a reception device that comprises the means for: According to the invention, it comprises, further, means for determining the values of count increments.

Reduction in the acquisition duration of a phase-locked loop able to reconstitute a synchronisation signal transmitted over an IP network

An apparatus for transmitting and receiving packets in a packet switching network that includes at least two stations. The apparatus includes a phase-locked loop, as well as means for receiving packets containing samples of the network, the samples being derived from data sampled every Tperiod, where Tis derived from a time base synchronized on all the stations of the network and the samples being associated with incremental values predicting at least one sample, calculating, in case of interruption of packet reception, a prediction of a sample that should have been received, by adding an increment value to a received sample value.

Secure mechanism for transmitting counter value in the context of transmission of a synchronizing signal in a packet network

A device is disclosed for transmitting packets in a packet communication network comprising at least two stations, including in particular means for generating a first timestamp from a sampled value of a master counter, means for generating a second timestamp from a sampled value of a second counter synchronized on the at least two stations and means for transmitting jointly the two timestamps in the packet communication network. A device is further disclosed for receiving packets in a packet communication network, which uses the double timestamp generated by the transmitter device.
