Hi,
Thanks for your response.
I would appreciate if could help me on something else. I have a scenario in
which I want to change the third scenario of RYU SDN Framework book QoS chapter
that described the Meter based QoS. In my scenario I have two queues, EF and
AF, on my switches. On the starting node of my flows I want to check these
queues and see whether the delay (or rate) of my EF queue degraded or not. If
it is the case I want to remark the flows that relates to EF to AF until the EF
queue delay gets back to its normal condition.
Considering the aforementioned scenario,
1) Can I implement this scenario using just the rules of meter? If so please
kindly help me find the right rules to help me achieve this.
2) otherwise, if you think I need to change the source code, what is the
appropriate source code module that I need to manipulate.
Thanking you in advance,
Ashkan

Subject: Adding queue to a switch using RYU QoS
x-mailer: Apple Mail (2.3124)
Hello,
Hope you are doing well.
I am using Ryu QoS on ubuntu 14.04 and mininet 2.2.1
All I've done is use the exact commands as said in the RYU SDN Framework book.
and after this command:
curl -X POST -d '{"match": {"ip_dscp": "26"}, "actions":{"queue": "1"}}'
http://localhost:8080/qos/rules/0000000000000001
I gtt this error:
Invalid rule parameter
So, I've restarted everything then I tried Qos per-flow. like before I used
ecaxt command as RYU SDN Framework book. After this command:
curl -X POST -d '{"match": {"nw_dst": "10.0.0.1", "nw_proto": "UDP", "tp_dst":
"5002"}, "actions":{"queue": "1"}}'
http://localhost:8080/qos/rules/0000000000000001
I’ve got the exact same error as before:
Invalid rule parameter
A "numeric string" like {"queue": "1"} causes this problem.
First, please try with non-string number like {"queue": 1}.
To fix this problem, I wrote the following patch,
but please note this patch is under reviewing in our team.

Subject: [PATCH] ofctl_utils: Enhance user value conversion
Currently, OFCtlUtil._reserved_num_from_user() fails to convert
an user specified value when it is a numeric string.
This patch enhances this conversion to enable to convert an user
value as follows.
e.g.)
- Integer: 1 -> 1
- Numeric string: "1" -> 1
- Reserved number: "OFPP_ANY" -> 0xffffffff
- Invalid value: "foobar" -> "foobar" (do not conversion)

Thanks,
Iwase
on the other hand, when I use "mark" in my actions command it easily adds the
rule and I can confirm it using get.
can you help me please solve this?
Thank you in advance!
