Hi,
I have found out that I can actually improve performance by using python's
multiprocessing library instead of multithreading, which gets around
python's GLI problem.
I also discovered a very weird problem, which is that if I try to add flows

Hi,
As I know, it is hard to improve performance by using multi-thread way
because there is a GIL problem in python.
Moreover, it might be slower if you try to using multi-thread to do simple
tasks.

Hi,
I was wondering if there is any difference in the speed in which I push
flows onto a switch serially or if I use multithreading in my app to push
flows. Would it still end up being serial at the end or would
multithreading reduce the latency?
Thanks,

Hi Hakan,
I was also looking to rename ports, but haven't found a solution yet.
Long-Term I will probably just do a rename in my ryu app: using the
original name internally and a different name for displaying.
To be honest I haven't used the ryu gui/topology viewer in a while. But

Hi Marvin,
thanks for your response.
At the moment no success. I need this because it is a requirement. Your
second suggestion sounds ok. I will think about it.
BTW:
Do you know a way to rename the port ids on hardware side? Not in Ryu.
Thanks.
And do you able to see a picture like this:

Hi,
I've just joined the list and found this in the archive. I don't know
how to respond to an older thread, so I post it here:
Have you had any success yet?
I'm also working with Ryu and HP switches and experienced similar
behaviours. As far as I understand this, it's not an issue with Ryu bu

Usage is described in Ryu-documentation.

No. Topology Viewer can work real environment.

Hi,
Hmm,,, I think that how to use app/ofctl_rest.py is correct.
Because following steps succeeded at my environment(Ryu ver3.18, OpenvSwitch
ver2.3.90).
1.Get flows stats.

Hi all,
I try to add flows on my OpenFlow Switch which is created on a HP 5900
as a OpenFlow instance. I am using app/ofctl_rest.py. When I send the

This Ryu app may be helpful.

Hello everyone,
I am developing an ryu application to calculate the best path during link
failure and push those best path to the switches. By using the dumper file I
managed to dump the events and using networkX I calculated the best path in my
application. But I could not figure out how to pus
Thanks a lot!
Now I can add flows perfectly.
Thank you again.
Best regards.

Hi!
I have problems adding flows. I add new flows as follows:
curl -d '{"dpid": "10002c59e55e2b00", "match": {"in_port": "0001"},
"actions": [{"type": "OUTPUT", "port": "0002"}]}'
