No, I can't guarantee that, only can do it inside OpenStack, it is limited.

It's good but it's limited can't be guaranteed, so I am asking is there any
other way without IP fragmentation so far.

Hello guys!

I have another important question regarding QoS mechanisms.

Does OVS with DPDK have a possibility to create multiple queues and put 
the traffic with different priorities to corresponding queues.

Is this what you are looking for ?

If not, will you put on the development of these features?

Thanks in advance!

Very best regards,

Aleksey

Hi guys,

  Seems OVS-DPDK still missing IP fragmentation support, is there any schedule 
to have it?
OVS 2.9
I'm  transferring to use OVN, but for those nodes which have external network 
connection, they may face this problem,
except to configure Jumbo frames, is there any other workaround?

I am not clear on the situation however.
You mention about configuring jumbo frames which means you can avoid the 
fragments by doing this ?
If this is true, then this is the best way to proceed since performance will be 
better.
What is wrong with jumbo frames ?
