The Linux traffic's control engine inaccurately calculates transmission times for packets sent over ADSL links. For some packet sizes the error rises to over 50%. This occurs because ADSL uses ATM as its link layer transport, and ATM transmits packets in fixed sized 53 byte cells.
What if AAL5 is used? The cell-alignment math is going to be wrong there surely?
