HP VAN SDN Controller benchmark (cbench)

[HansChristian]

Hi,

is there a good way to test the controller's performance?

I tried cbench, but without an additional SDN application, no packet-out messages to count by cbench are generated. And with an additional SDN application which sends packet-out messages in response to packet-in messages generated by cbench, I see the following error message in /opt/sdn/virgo/serviceability/logs/log.log

com.mango.cbenchtestapp.impl.CbenchTestAppManager                 com.hp.of.lib.InvalidMutableException: {ofm-X:[V_1_0,FLOW_MOD,80,4591795],cmd=ADD,match={Match(V_1_0):[type=STANDARD,len=40],fields=ETH_TYPE,IP_PROTO,IPV4_SRC,IPV4_DST},...}

Can anybody help?

Thanks!

Could you check the hybrid.mode setting in ControllerManager? If hybrid.mode=true, then the controller will only respond to packet-in messages which it has explicitly requested (ie: ARP, DHCP, BDDP). If you change the setting to hybrid.mode=false, you should see the VAN controller respond to packet-in messages. The responses will be coming from the "Path Daemon" application, which is installed and active by default (but only operates when hybrid.mode=false).

NOTE. You'll need to restart the controller process (via "sudo service sdnc stop" and "sudo service sdnc start") after changing the hybrid.mode setting.
