rest_qos.py suppose to be processed on Flow Table pipeline processing,
modify simple_switch_stp_13.py to register flow entry into table id:1.
modifications example: add_flow
mod = parser.OFPFlowMod(datapath=datapath, priority=priority,
match=match, instructions=inst, table_id=1)
modifications example: delete_flow
mod = parser.OFPFlowMod(
datapath, command=ofproto.OFPFC_DELETE,
out_port=ofproto.OFPP_ANY, out_group=ofproto.OFPG_ANY,
priority=1, match=match, table_id=1)
Please refer to the following for QOS.
https://osrg.github.io/ryu-book/en/html/rest_qos.html
Please try to start the ryu-manager with the following command.
ryu-manager ryu.app.rest_qos ./simple_switch_stp_13.py
ryu.app.rest_conf_switch
The following is the result of running in my environment.
