Have you read the sections on qos and queue in 'man
ovs-vswitchd.conf.db' ? That should provide some details. I think OVS
design tries to follow the corresponding Linux tc implementation.
There is a parent class and a bunch of sub classes there. I see qos
table as something that defines the type of QoS (e.g: linux-htb,
linux-hfsc) and provides an ability to set a max-rate for all the
underlying queues and acts as a parent. Queue table is used to provide
more fine-grained control for specific type of traffic going through a
port.
