I personally set all the children to a low value for rate, but give them a high ceiling, this way the parent has a lot of flexibility. Don't forget that the 'rate' in htb is essentially a guaranteed throughput. However, I find HFSC more flexible, although somewhat harder to understand. -- Mike SCHMIDT CTO Intello Technologies Inc. mike.schmidt@xxxxxxxxxxx Canada: 1-888-404-6261 x320 USA: 1-888-404-6268 x320 Mobile: 514-409-6898 www.intello.com -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
