Hi, IIRC, cbench supports ONLY OpenFlow 1.0. So, simple_switch_13.py (which supports only OpenFlow1.3) can not communicate with it. Please confirm the OpenFlow version definition of your app includes OpenFlow 1.0.
The following is the definition of simple_switch.py (which supports OpenFlow 1.0). https://github.com/osrg/ryu/blob/master/ryu/app/simple_switch.py#L33 Thanks, Iwase On 2016年10月09日 23:58, Ezzat Zar wrote: > 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/base/app_manager.py", line 484, in > instantiate_apps > self._instantiate(app_name, cls, *args, **kwargs) > File "/home/ubuntu/ryu/ryu/base/app_manager.py", line 466, in _instantiate > ofproto_protocol.set_app_supported_versions(cls.OFP_VERSIONS) > 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. > > > > ------------------------------------------------------------------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, SlashDot.org! http://sdm.link/slashdot > > > > _______________________________________________ > Ryu-devel mailing list > Ryu-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/ryu-devel > ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Ryu-devel mailing list Ryu-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ryu-devel
