Technique for communication in a communications network with routing by name

A routing device in a communications network performing routing by name, the device being arranged to aggregate a plurality of requests relating to a data segment of a stream into an aggregated request and comprises:

• storage means for storing data segments belonging to different streams in a queue in order to route them to client entities that have requested the data segments;
• determination means for determining a credit associated with a stream, said credit varying as a function of a number of requests transmitted by client entities and relating to data segments belonging to the stream;
• routing means for routing a data segment to client entities that have requested the data segment, after extracting the data segment from the queue;
• stream selection means arranged to select a stream having at least one data segment B stored in the queue and for which the associated credit is the smallest;
• and
• deletion means for deleting the data segment B belonging to the selected stream from the queue;
• said selection and deletion means being activated when the memory space available in the queue does not enable a received data segment A to be stored, and said storage means being configured for storing the data segment A in the queue after the deletion means deletes data segment B from the queue.

A hardware storage medium comprising a program stored thereon for a routing device, the program comprising program code instructions for controlling execution of steps of a communications method, when said program is executed by said routing device, in a communications network that performs routing by name, said device being suitable for aggregating a plurality of requests relating to a data segment of a stream into an aggregated request and for storing data segments belonging to different streams in a queue prior to the device routing them to client entities that have requested them, wherein the method comprises:

• a step of the routing device determining a credit associated with a stream, said credit varying as a function of a number of requests transmitted by client entities and relating to data segments belonging to the stream;
• and
• on receiving a data segment A in response to an aggregated request, and when memory space available in the queue does not enable said received data segment A to be stored:
• a step of selecting a stream that has at least one data segment stored in the queue and for which the associated credit is the smallest;
• and
• a step of deleting from the queue a data segment B belonging to the selected stream;
• said method further comprising:
• a step of storing the data segment A in the queue;
• and
• a step of routing the data segment A to client entities that have requested the data segment A, after extracting the data segment A from the queue.
