7.0 QOS reference example

In this QOS chapter, we're going to implement this example shown in Open vSwitch documentation:

3 hosts: WorkstationA, WorkstationB, WebServer connected to br0 bridge.

• WorkstationA (10.0.0.5) is connected to br0 with port PA (of port number 5 as shown in a).
• WorkstationB (10.0.0.6) is connected to br0 with port PB (of port number 6 as shown in b).
• WebServer (10.0.0.10) is connected to br0 with port PW (of port number 10 as shown in w).

Let's run iperf between WorkstationA and WebServer.

Without QOS limitation, we can reach 31.9Gbit/s

Now, we want to limit traffic:

• 10 Mb/s from WorkstationA to WebServer.
• 20 Mb/s from WorkstationB to WebServer.

First need to define queues
