QoS enquiry on CBWFQ

wmmak · ‎10-10-2007

Hi all,

For example, in CBWFQ, I have two queues

The whole pipe is 20Mb

Queue 1 (higher priority)

bandwidth 10Mb

Queue 2 (default queue)

If congestion occur, queue 1 guarantee 10Mb. Is queue 2 only occupying at most 10Mb even though there is less than 10Mb in Queue 1?

Thanks you for your help

Regards,

mak

Queue 2 would take advantage of excess bandwidth not being used by queue 1.

The "bandwidth" setting within a CBWFQ class, except for LLQ, provides a minimum guarantee of bandwidth for that class.
