Hi,
you need an ovsdb bridge object:
from ryu.lib.ovsimport bridge
ovsdb_bridge= bridge.OVSBridge(conf, datapath.id, config_path)
Konsole outpthe "conf" can be obtained from RyuApp.self.conf.
the "config_path" must be for example "tcp:127.0.0.1:6632", but you have to open the
manager for that port. You can do this in your terminal with "ovs-vsctl set-manager
ptcp:127.0.0.1:6632".
Konsole outpu
then, for a specific port you have to set the qos-entry. For example like this:
ovsdb_ovsdb.set_qos(
"eth0",
queues=[{'min-rate': '10000', 'max-rate': '100000'},{'min-rate': '500000'}],
max_rate="100000000")
This will setup 2 queues for port "eth0". The first queue will have 10kbit/s
min-rate and 100kbit/s max-rate,
the second queue only has a min-rate of 500kbit/s. The max-rate QoS for port "eth0"
limits "eth0" to 100Mbit/s
Konsole outp
Ovsdb will use linux-htb to implement the queues. So you when you type "tc -s class
show dev eth0" in your terminal you can see if the linux-htb queues are set up
properly.
Konsole output
Kind Regards Valentin

Helle all,
I failed to set queues to openvswitch port by ovsdb in ryu. could
someone give me an example?
I have tried the rest_qos.py app. For QoS, it is ok. But, it is not OK for queues.
Best Regards
