Dear Carlos Ferreira,
Currently, my set up is based on a proactive approach. RYU controller will
assign the forwarding rules proactively to the openflow switch. Let me
recall back my simple topology. GW1------host1-----host2-----GW2. RYU
controller is in the GW1. host1 & host2 sends the data to the GW1. My
assumption is, for eg, when host 1 increase CPU utilization or some
condition, it will send packet-in message to the RYU controller. When RYU
receives the packet-in message from the host1, it will delete the
forwarding rules in host 2 and install the forwarding rules in host2 to
send its data GW2. something like the load-balancing scenario.
Best Regards,
Soe Ye Htet
