Patent ID: 7050403

Claim:
A method for classifying packets in a packet network (NW), comprising the steps of: detecting (S 1 ) the length (L) of a packet, and classifying (S 2 , S 3 , S 4 ) the packets depending on the detected length (L), wherein said classifying step (S 2 , S 3 , S 4 ) further comprises a first comparing step (S 21 ) for comparing said length (L) with a first predetermined threshold (TH 1 ), wherein said classifying step further comprises a second comparing step (S 22 ) for comparing said length (L) with a second predetermined threshold (TH 2 ), said first threshold (TH 1 ) being lower than said second threshold (TH 2 ), wherein a packet the length (L) of which is below said first threshold (TH 1 ) is classified as a first type of packets (S 3 ) and a packet the length (L) of which is above said second threshold (TH 2 ) is classified as a second type of packets (S 4 ), and a packet the length (L) of which is between said first threshold (TH 1 ) and said second threshold (TH 2 ) is classified (S 32 , S 33 ) by referring (S 31 ) to an identifier arranged in the packet.
