A method and an equipment for packet prioritization when routing data packets is presented. Several priority classes are defined for the packets, and a first threshold value and a second, higher, threshold value is defined for each prioity class. In association with each packet, the oldest packet of a given prioritiy class is selected, and if the packet is older than the second threshold value of the priority class concerned, the packet is discarded, and the next priority class is selected. If the packet is older than the first threshold value of the priority class concerned, at least one packet of this priority class is transmitted until the oldest packet in the priority class is younger than the first threshold value of the priority class concerned, whereupon the next priority class is selected. |
