Thanks Iwase.
Is it possible to run the same instance of ryu and have it acting as master
and slave. Or do we need to have two separate machines , with ryu running
on each one of them.
With respect to HA, what is the time taken for newly elected master to
assume its role. Eg: suppose the current master crashes and a new master
had to get elected. How much time and what are sequence of steps carried
out in RYU.
Just read in the following link that it is possible to have same instance
acting as master and slave.

$ ryu-manager --ofp-tcp-listen-port 6653
$ ryu-manager --ofp-tcp-listen-port 6654
Thanks,
subha.
