Hi, I tried your topology script and your app on my environment, the ARP broadcast storm has occurred.
I have not investigated why further, please confirm your app (multipath.py) can cooperate with simple_switch_stp_13.py. For example, simple_switch_stp_13.py installs the flows for L2 switching into Table 0 with priority 0 by the default and your app (multipath.py) seems to install the flows into the same Table with the same priority. I guess these apps have some logical conflicts in the flow table...
