Do you know why I was convinced that my rule was OK? Because I always followed my own rules :) I did some small tests : ceil rate 1 200 200 \- 10 200 100 \- 100 200 100 \- 101 200 100 \- 20 200 100 Traffic in 100, 101 and 20 : each gets 67 (33%) Parent rate (10) is not respected otherwise 10 should share 50% with 20. Traffic in 100 and 20 : each gets 100 (50%) If you respect "sum (rate of childs) = parent rate" it works like expected : ceil rate 1 200 200 \- 10 200 100 \- 100 200 50 \- 101 200 50 \- 20 200 100 Traffic in 100, 101 and 20 : 20 gets 100 (50%), 101 50 (25%) and 101 50 (25%). Traffic in 100 and 20 : each gets 100 (50%) Conclusion : if you want to know how traffic will be shaped, you have to follow some basic rules. I will update docum.org tonight.
