Hi Kiran,
It generally means there is another application using the port (6633).
This is default port RYU listens on. Run a "netstat -nltp | grep 6633" to
see what application is using it. You can kill it and retry.
Optionally start RYU on a different listen port:
$> ryu-manager --ofp-tcp-listen-port 5555 --verbose
Regards,
Nitish

Want excitement?
Manually upgrade your production database.
When you want reliability, choose Perforce
Perforce version control. Predictably reliable.
