I had the impression that I could use CBQ/WRR to get a LLQ to certain selected flows by defining a class with higher priority then others.
I have three classes defined;
- one for CBR flows, simulating VoIP, prio 1
- one for VBR flows, simulating Video on Demand, prio 3
- one for best effort, prio 3
With quite high congestion on the best effort class (about 3% packet
drops) and with the VBR flows on occasions using more then allotted my
measurements shows on jitter of up to 6 ms on 3 of 10 VoIP flows.
The distans between the packets should be less then 0.7 ms without
jitter with the bandwidth used on the link.
Am I wrong in my assumption on the LLQ effect of priority to one class?
Any help would be appreciated.
Thank you in advance
Best regards
