Title: METHOD AND ROUTER IN A PACKET NETWORK WITH PRIORITY CLASSES
Abstract:
A method and an equipment for packet prioritization when routing data packets. Several priority classes are defined for the packets (F), and a first threshold value (T1) and a second, higher, threshold value (T2) is defined for each priority class. In association with each packet, the oldest packet (F) of a given priority class is selected, and if the packet is older than the second threshold value (T2) of the priority class concerned, said packet (F) is discarded, and the next priority class is selected. If said packet (F) is older than the first threshold value (T1) 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 (T1) of the priority class concerned, whereupon the next priority class is selected.
