Thanks, Thomas for forwarding this to the group.

I have one more question. Does DPDK QOS uses any internal threads/timers for the token bucket implementation?. The token

buckets can be implemented in different ways. When are the tokens are filled, I see there is tb_period?

It looks like the tokens are filled when the HQOS thread is trying to find the next active pipe?

Regards,
