Hi, Deni
Of course, you can modify codes as you want, including bridge.py.
And, about the exception you got, the response from OVS may be delayed
due to network delay.
Please try to extend the timeout, e.g. 2, 3, and so on.
Thanks,
Fujimoto

Hi Fujimo
Hi Fujimoto san,
Thank you for the information.
To add the port, I didn't use "run_command()" in bridge.py. To be honest, I
didn,t know yet how to use it :). However, to add the port, I was trying to
add function (add_port) in bridge.py. The function is very similar to the
del_port function. It wa
Hi, Deni
If APIs in bridge.py are not enough to satisfy your demand, you can use
"run_command()" in bridge.py.
"run_command()" calls functions in vsctl.py.
I think you will be able to add/delete bridges by using this function. :)

Hi Fujimoto san,
Thank you very much for the code. I have ran it and it was working. Thanks,
you have saved my days.
Btw, I have another questions related to this issue. I do hope you will not
mind :)

Hi, Deni
In your application, I think there is no one which calls "ovs_bridge()".
It is better to implement your code in Event Handlers.
For example, Features Reply Handler will be called when your application
gets the Features Reply message
(≒ when the connection to the OVS is established).

Dear Fujimoto san, thank you very much for your information.
I have tried to put the code to the file: simple_switch.py (as in
attachment), and try to run it in Ryu controller machine.
The code is running, how ever, when I checked in the OVS machine (VM IP:
10.0.0.5), there is no changes. The port
Hi, Deni
You can make a connection by instantiating OVSBridge:
ovs_bridge = OVSBridge(None, datapath.id, 'tcp:127.0.0.1:6632',
timeout=1)
And by the following code, for example, you can delete a port:
ovs_bridge = OVSBridge(None, datapath.id, 'tcp:127.0.0.1:6632',
timeout=1)
Hi Satoshi san, thank you for your kind reply.

Hi, Deni
The problem may be caused by that you use "ovsdb_event" and "ovs_vsctl"
at the same time.
If you don't need to monitor the status of OVS, you should not use
"ovsdb_event".
Also, you can use "OVSBridge" to control your OVS.
"OVSBridge" calls "ovs_vsctl.VSCtl()" in __init__(), and wrap
Dear all,
Currently, I am trying to make a connection between Ryu Controller and OVS,
and trying to modify OVS from controller (add bridge, add port, delete
port, etc) dynamically.
Currently, the OVS and Ryu controller can be connected. They are running in
different VM. However, when I try to run
