so resurrecting this topic... maybe this delay has
something to do about TCP protocol.
Because when I test UDP protocol with iperf the
Response time is really fast when i drop a link
With link down command on mininet.
But when I test TCP protocol on iperf and use
Link down command everything becomes zero
With no convergence of links to another route.
I think is related with ARP message.
I would like to know if this makes sense to someone?
