ABSTRACT:
A method of controlling a queue buffer (2), said queue buffer (2) being connected to a link (1) and being arranged to queue data units (30) that are to be sent over said link (1) in a queue (20), comprising: determining (S1) a value (QL; QL?av#191) of a length parameter related to the length of said queue (20), comparing (S2) said value (QL; QL?av#191) with a length threshold value (L?th#191; min?th#191; max?th#191) and performing (S3) a congestion notification procedure if said value (QL; QL?av#191) is equal to or greater than said length threshold value (L?th#191; min?th#191; max?th#191), and an automatic threshold adaptation procedure (S4, S7), where said automatic threshold adaptation procedure (S4, S7) is arranged to automatically adapt said length threshold value (L?th#191; min?th#191; max?th#191) on the basis of one or more characteristics of said link (1).
