Provide simple switch with QoS by using ryu-controller in both openflow 1.0 and openflow 1.3
###Requirements
This project is a very simple implementation by using OVS queue and Openflow protocols.
These codes are tesed by:
Ryu 3.3
Mininet 2.1.0 (should also work in 2.0.0, but node.py we offered is modified from 2.1.0)
OpenVSwitch 1.11.0 (any version >=1.10.0 which supports Openflow 1.3 protocol should work)
###Thanks
We use the same way that floodlight-qos-betta implements in Floodlight.
