Hello. I've been experimenting with QOS, using he REST API, with the help of this tutorial: https://osrg.github.io/ryu-book/en/html/rest_qos.html Now, I got to the point where the switch is recognized by the scripts:
$ ryu-manager ryu.app.rest_qos ryu.app.qos_simple_switch_13 ryu.app.rest_conf_switch loading app ryu.app.rest_qos loading app ryu.app.qos_simple_switch_13 loading app ryu.app.rest_conf_switch loading app ryu.controller.ofp_handler instantiating app None of DPSet creating context dpset instantiating app None of ConfSwitchSet creating context conf_switch creating context wsgi instantiating app ryu.app.rest_qos of RestQoSAPI instantiating app ryu.app.qos_simple_switch_13 of SimpleSwitch13 instantiating app ryu.app.rest_conf_switch of ConfSwitchAPI instantiating app ryu.controller.ofp_handler of OFPHandler (784) wsgi starting up on http://0.0.0.0:8080 [QoS][INFO] dpid=00000800277958c2: Join qos switch. # right here However, from this point, even though I've "set-manager" manually in the switch (port 6632) and also created its system-id (which is the same has the datapath value shown on Ryu), all "curls" show the following message: $ curl -X PUT -d '"tcp:172.16.1.100:6632"' http://localhost:8080/v1.0/conf/switches/8796755286210/ovsdb_addr <html> <head> <title>404 Not Found</title> </head> <body> <h1>404 Not Found</h1> The resource could not be found.<br /><br /> </body> $ curl -X POST -d '{"port_name": "eth3", "type": "linux-htb", "max_rate": "10", "queues": [{"max_rate": "50"}, {"min_rate": "80"}]}' http://localhost:8080/qos/queue/8796755286210 <html> <head> <title>404 Not Found</title> </head> <body> <h1>404 Not Found</h1> The resource could not be found.<br /><br /> </body> Why is this happening? Also, in the controller, this message appears everytime I execute each curl: (784) accepted ('127.0.0.1', 55198) 127.0.0.1 - - [12/Feb/2020 22:37:14] "PUT /v1.0/conf/switches/8796755286210/ovsdb_addr HTTP/1.1" 404 278 0.000777 I've checked the flow entries of the switch, and no new flow entry appears... So why does this message says "accepted"? Thank you for your time, Ines
