I have 1024 Mbit link to Internet. This link is shared by 3 LANs on my linux box. And now - I have to design that these 3 LANs gets some fragment of bandwidth. For example, rates are: 128/384/512. Ceil is always at link speed. I keep rule from FAQ on www.docum.org, which learn us: sum of childs rates <= ceil of parent. But if I define 3 classes based of customer conception (paying for desired bandwidth), where is place for creating some interactive classes for traffic like ICMP, ACK responses and so on ? If I define next class, give it highest priority, rate of 512 kbit, this exceeds rule from FAQ, because 128+384+512+512 is not 1024 at all ;-) So, how to resolve this kind of problem ? Or better I have to change conception, and assume that I must create all kind of classes (interactive, for big traffic and others) WITHIN parent customer classes, on 'per customer' basis ?
