Our config at the moment is 64k upstream and 384 downstream. I would like to set up the upstream QoS polixy/shaping for allowing real-time protocols, in my case VoIP (RTP). I would like to know what should you recommend to use (theoretical solution possible based on experience :). I tryed CBQ and allow RTP packets to have the required bandwidth, but while the delay is the most important parameter for RTP, the quality was terrible (when I did full upload). Because of the required minimum delay, I set up a PRIO queuing where I did 3 bands (1st: RTP, 2nd: intercative e.g. SSH, 3rd: bulk traffic). Now the quality is acceptable. (I put SFQ to those bands) My question is: is it possible to make better configuration for real-time protocols (upling with narrow bandwidth)?
