Hi
For me, I just start multiple Ryu controller with different IP/TCP port
And create connection between controllers(by simple socket)

How do you create multiple instances of the Ryu controller?

Hi
In my opinion, you can create multiple instance of Ryu controller, and
connect switch to all controllers.
You need to design mechanism for syncing flow data between multiple
controller instances.

Alright thank you. So I guess there is no method to send out multiple flows
in parallel by Ryu?

I think, even if you only start one single process to add a flow, the
connection (object) between the controller and switch is still owned by the
root process, in which you start your delegate process. In the case that you
want to add more computation capacity, maybe you can perform the computat
I am testing the controller to do parallel flow addition/deletions, in
order to see how fast the controller can add or delete a large number of
flows. Because in a large network, you may need to add thousands of flows
and it needs to be done in parallel so that the network can be scalable.
You may

Hi,
I ran it with --verbose and nothing out of the ordinary appeared.
I'm not sure what you mean by sharing OpenFlow sessions between processes.
I'm just attaching the function that adds flows into different processes,
like I have a function called add_flow(in_port, out_port, ip_dst, ...), and

Also, I am not sure if you processes did send OpenFlow message correctly.
Can you verify OpenFlow messages sent by controller by using tcpdump or
Wireshark?

Is there any warning/error log? (run Ryu with --verbose)
How did you share OpenFlow sessions between processes?

Hi,
How do you create multiple process? You create multiple Ryu process?
If you create multiple Ryu process, you need to connect switch to all
process.
Or you need to share the connection between processes and switches

Hi,
In order to add flows in parallel from a controller I'm using python's
multiprocessing library to create separate processes, each to add flows.
However I've observed that in many situations flows don't get properly
added. Can you please help?
Thank you,
