Method for pre-empting transmission resources for real-time data routing

A device for allocating at least one transmission resource from among a plurality of resources, intended for routing a first item of data relating to a first application in a communication infrastructure, the device comprising:

• a receiver, able to receive, from a centralized management entity, an allocation message for allocating a plurality of resources comprising a set of transmission features for a second item of data relating to a second application, and
• a processor configured to:
• assign at least one resource of the plurality to the transmission of the first item of data, and
• select a feature of the set for transmission of the second item of data on the resources of the plurality that are not assigned to the transmission of the first item of data.

A system for allocating at least one transmission resource from among a plurality of resources, intended for routing of a first item of data relating to a first application in a communication infrastructure, comprising:

• a distributed management entity comprising an allocation device for allocating at least one transmission resource front among a plurality of resources, intended for routing a first item of data relating to a first application in a communication infrastructure, the allocation device comprising:
• a receiver, able to receive, from a centralized management entity, an allocation message for allocating a plurality of resources comprising a set of transmission features for a second item of data relating to a second application, and
• a processor configured to:
• assign at least one resource of the plurality to the transmission of the first item of data, and
• select a feature of the set, tor transmission of the second item of data on the resources oi the plurality that are not assigned to the transmission of the first item of data, and
• the centralized management entity comprising:
• a processor configured to assign the plurality of resources comprising the set of transmission features to the transmission of the second item of data, and
• a transmitter, able to transmit, to the distributed management entity, the allocation message for allocating the plurality of resources.
