It is just to make ceil thing there is no bandwidth available. I know that parents in theory must be equal or more than childs sum and etc. About strange cburst/burst i will explain in next part. > > > I will try to use lartc, if it is better to not "spam" my stuff here :-) > > Maybe you don't believe it, but I really knew much more about > properly setting HTB parameters 2 years ago, when I read lartc or > not worse our local linux networking news group than now - when, > this practical knowledge was mostly erased by some 'useless' inside details. For bandwidth sharing it is perfect, but i want just to make things, which i did with TBF - some time bursty speed, and then slow down to lower speed if customer is using too much. In theory it has to work like this, but in practice i am hitting wall. I tried it about 1 year ago, it was same thing, just with another conditions. Seems cburst/burst a bit different thing, just to make load on CPU by HTB less , at high speeds. > > > I didn't try yet PSPacer yet, as ESFQ things.

On my experience people don't like much talking on mails, sending bug reports and etc. I know a lot of people who have kernel panic, oops issues, and who don't know what to do, just to blame "linux". Now i am trying to help them and also to help improve linux this way. For me personally more interesting right now ESFQ way. Just i am scared to put in producting patches not from mainline, cause then on issues i cannot write proper bugreport. > > Jarek P. > -- > To unsubscribe from this list: send the line "unsubscribe netdev" in > the body of a message to [EMAIL PROTECTED] > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Denys Fedoryshchenko Technical Manager Virtual ISP S.A.L. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
