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 (S 1 ) a value (QL; QL?av# 191 ) of a length parameter related to the length of said queue ( 20 ), comparing (S 2 ) said value (QL; QL?av# 191 ) with a length threshold value (L?th# 191 ; min?th# 191 ; max?th# 191 ) and performing (S 3 ) 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 (S 4 , S 7 ), where said automatic threshold adaptation procedure (S 4 , S 7 ) 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 ). |
