Thanks Stef Yep i missunderstood the quantum concept (itīs clear now), but since my voip class was configured with enough bw this doesnīt matter Reading more on docum.org, i find hte possible cause of the delays i was using sfq (128p queue) on the leaf i removed sfq from the voip class I will try also with other disciplines.. like tbf just to have a deeper understanding of queuing in real life applications Are there any recomendation on which queuing discipline to use with voip? (my stats show 100 bytes per packet average in voip) iīm doing more tests now and iīll re re-read the full lartc. doc regards --- Stef Coene <stef.coene@docum.org> wrote: > On Thursday 13 February 2003 00:59, Victor Cassar > wrote: > > Well > > > > I understand why quantum should be at least equal > to > > mtu size > > > > but letīs think in this > > > > if i have a dsl link and i want to give more > quality > > to > > "one voip user" > > iīve already solved the dsl upload problem > transfering > > the bottleneck to my shapping box. > > > > Should i change the quantum to a lower value for > that > > class? > > > > any ideas or comments about this? > Do you know where quantum is used for?
