Thanks for your response, Ben!
Yeah, I tried configuring qdisc through ovs-vsctl by manipulating Qos/Queue. It
works fine on OVS supported qdisc HTB/HFSC.
For TOS thing I've mentioned in previous mail, one convenient way is to use u32
selector in tc filter, or use netfilter to get packets go into certain queue. I
think that should work fine, too. But the disadvantage is that , this part of
configuration is not tracked by OVSDB. Seen from management plane, there're two
separate operations to achieve this goal through different management
interfaces.
So I wonder it there's a better method, a consolidated one. You mentioned that
writing OF rules may help. Would you like to give me some hints on how to
achieve that? Thanks very much.
Best,
Robin

You should be able to achieve the qdisc configuration through OVS
configuration of the QoS and Queue tables.
I'm not sure whether you can tie TOS to queue without writing OpenFlow
rules.
