REST API to create flow with action "enqueue" for QoS.

DeepakMalik — Tue, 29 Oct 2013 06:41:15 GMT

We have seen REST APIs for metering support.
But to achive this in openflow spec v1.0, we are looking for flow creation with enqueue action.

We could not find a REST API that can support enqueue action. Is this option supported?

Thanks in advance.

Check out the "Flow creation via REST API" post

This will show you how to get the JSON schema.

There you should see that "enqueue" can be used as an action when creating a flow.

Hope this helps.

Thanks Dave.

I had doubt on my controller version, so I have upgraded to 2.0.0. But still, I am seeing the same issue with "enqueue" action.

Please see the screenshot for the reported issue.

I just had a quick look at the OpenFlow spec.... (see links below)

The "set-queue" action doesn't appear to be a valid action in 1.0 (but it is in 1.3).

It appears HP's OpenFlow library does some magic mapping between "set_queue" and "enqueue" and this might be where the error comes from...

Could you try using "enqueue" for now to see if this works?

Let me know how you get on!

Yes Dave. "enqueue" action is mentioned in the 1.0 and our application currently support 1.0. We tried using "enqueue" action, but it appears that action enum type as "ENQUEUE" is not defined.(see the attached screenshot)

Whereas, it seems "set_queue" action was accpeted as valid enum. But it throws a different error. (as shown in previous screenshot).

Thanks

Maybe the vlan priority can help to put the traffic in the right queue.

so:

{"instructions":[{"apply_actions":[{"set_field":{"vlan_pcp":2}},{"output":4}]}]}

with OF 1.3 and above you can also use rate limiters. I need to dig into this part how to use it.
