Hi,
I have a simple packet_in handler Ryu app and I want to know how many other
packet_in(s) the Ryu controller could afford responding (with cbench I
guess) with and without my app running.
When I run
./bin/ryu-manager ./ryu/app/simple_switch_13.py ./ryu/app/cbench.py
I get the error:
=================================================================
loading app ./ryu/app/simple_switch_13.py
loading app ./ryu/app/cbench.py
loading app ryu.controller.ofp_handler
instantiating app ./ryu/app/simple_switch_13.py of SimpleSwitch13
instantiating app ryu.controller.ofp_handler of OFPHandler
instantiating app ./ryu/app/cbench.py of Cbench
Traceback (most recent call last):
File "./bin/ryu-manager", line 19, in <module>
main()
File "/home/ubuntu/ryu/ryu/cmd/manager.py", line 91, in main
services.extend(app_mgr.instantiate_apps(**contexts))

File "/home/ubuntu/ryu/ryu/ofproto/ofproto_protocol.py", line 46, in
set_app_supported_versions
assert _supported_versions, 'No OpenFlow version is available'
AssertionError: No OpenFlow version is available
=================================================================
The only way it works is to run:
./bin/ryu-manager ./ryu/app/cbench.py
and then launching cbench from oflops. but this does not include my app's
effect on controller performance.
Any idea how to do this?
Thanks.
