ABSTRACT:
A device comprising i) input ports and output ports for receiving and transmitting data packets, ii) a receiver to extract primary switching or routing data and secondary data to be handled and to associate the secondary data with a selected storage address, iii) a memory for storing the secondary data extracted at the storage address, iv) a switching stage and a routing stage configured to receive the storage address and the primary switching or routing data and to determine tertiary data designating at least one of the output ports and to determine new primary data, v) extracting the tertiary data and the new primary data from the switching stage and the routing stage to deliver the data and the storage address as a function of a selected criterion, and vi) sending the secondary data stored at the storage address, combined with the new primary data to each output port designated by the tertiary data.
