Hello everyone,
I use socket to implement the communication with controllers and it work
perfect now.
But the disadvantage is : It only can detect the fail from controller
instead of the link between the switch and the controller.
Therefore, I would like to ask:
What is the common way to implement
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
Hi Tarun,
I guess you need to find out why your switch do reconnect to Ryu in
your situation, first.
Please confirm your switches' settings and logs.
(e.g., Do your switch check the connection to Ryu with OFPT_ECHO
message?)
Thanks,
Iwase

For OpenFlow 1.5, we make binary files based on OpenFlow Specification,
and use them to test.
In testing, we make Ryu to parse and serialize the binary da

Hi, Markku
Thanks, I succeeded to reproduce your problem.
The cause is that rest_pos.py does not support LLDP(ether_type: 88cc).
The quick fix is making rest_qos.py to support LLDP, so:
diff --git a/ryu/app/rest_qos.py b/ryu/app/rest_qos.py
index 9fe72ed..6e750e6 100644
--- a/ryu/app/rest_qos.p
Hi, Markku
ofctl_rest.py receives "dpid" as integer, so you have to use "GET
/stats/desc/10".
However, ofctl_rest.py is an example application, so you can modify
ofctl_rest.py as you want.
I suppose you may modify:
https://github.com/osrg/ryu/blob/master/ryu/app/ofctl_rest.py#L199
The second
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?

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
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
