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.
I guess it is depending on the algorithm of selecting the master, but it is out
of scope of the
OpenFlow Spec and depending on the implementation of your switch and your
applications.
Please refer to "6.3.7 Multiple Controllers" section of the OpenFlow Spec 1.3.5
for the details.
Just read in the following link that it is possible to have same instance
acting as master and slave.
https://www.mail-archive.com/ryu-devel@lists.sourceforge.net/msg13338.html
$ ryu-manager --ofp-tcp-listen-port 6653
$ ryu-manager --ofp-tcp-listen-port 6654
Or you can specified the listen IP address with '--ofp-listen-host':
$ ryu-manager --help
...(snip)...
--ofp-listen-host OFP_LISTEN_HOST
openflow listen host (default 0.0.0.0)
--ofp-ssl-listen-port OFP_SSL_LISTEN_PORT
openflow ssl listen port (default: 6653)
--ofp-tcp-listen-port OFP_TCP_LISTEN_PORT
openflow tcp listen port (default: 6653)
...(snip)...
Thanks,
Iwase
Thanks,

Hi Subha,
By default, Ryu will wait for the connection from switches on port 6653 and
6633, So most of the
required configuration is on switch side, I guess.
If you are using Open vSwitch, please execute the following command on your
switches.
$ ovs-vsctl set-controller <switch_name> "tcp:<controller1_addr>:6653"
"tcp:<controller2_addr>:6653"
Optionally, if you want to tell switches which controller is Master or
Slave, send OFPRoleRequest
message from your Ryu application.

Making it a bit clearer. I want to have two controller running
simultaneously with one as
Master and one as Slave.
Any pointers on how to achieve this will be helpful.
Thanks,
subha.
