Well, there are a lot of reasons why CBQ may not fit your needs. I really want to downplay the 'holy grail' status it has achieved. New text: You may wonder what happens to traffic that is not classified by any of the two rules. It appears that in this case, data will then be processed within 1:0, and be unlimited. The unfiltered behaviour can be configured in a variety of ways, which have not yet been documented adequately. HTB is clearer in this respect, so you may prefer it. > I've seen other documents that describe the options the author says he > doesn't understand whose authors like CBQ and/or believe it to be > well-designed.

If you see CBQ working well, you are probably on an empty 10 or 100mbit segment, talking directly to the switch, or using a plain-old-modem with a fixed bitrate. In other cases, CBQ is 'saved' because it actually contains token bucket filters, which ARE pretty accurate. CBQ relies on being dequeued at a well known rate, which is simply not always the case. Furthermore, often there is no 'well known rate', for example when using a PPP-over-Ethernet modem over a userspace socket. Anyway, 'use HTB :-)' may indeed not be appropriate and has been changed, thanks.
