Hi everyone.
I'm updating cbench to emulate OpenFlow 1.4 switches (instead of 1.0) and I
just tested it against Ryu.
I noticed that there's a "cbench.py" app that I suppose it is to be used
when benchmarking Ryu. As I'm new to Ryu, I would like to know if I'm doing
things right.
So, from ryu main folder, i ran "./bin/ryu-manager ryu/app/cbench.py" and
started the original version of cbench, getting this result:
*RESULT: 16 switches 15 tests min/max/avg/stdev =
5191.99/5742.99/5514.55/163.41 responses/s*
Then I tried running my updated version of cbench, but seems like this app
isn't ready to deal with OF 1.4 switches, as I got this error: AttributeError:
'OFPSwitchFeatures' object has no attribute 'ports' (full output in the end
of the email).
Because of this, I decided to test Ryu running the
"ryu/app/simple_switch.py" since it had the counterpart
"simple_switch_14.py" and both versions of cbench worked:
Cbench vs Ryu's simple_switch.py:
*RESULT: 16 switches 15 tests min/max/avg/stdev =
2047.69/2560.00/2315.53/215.48 responses/s*
Cbench 1.4 vs Ryu's simple_switch_14.py: *RESULT: 16 switches 15 tests
min/max/avg/stdev = 869.00/1270.03/1140.63/117.47 responses/s*
I would like to know if these values are common/expected or if I'm doing
something wrong (either in launching ryu or if the Cbench 1.4 values look
"weird).
Thanks in advance!
