The average size of each flv video is 60Mb+. We've five content servers
(nginx-1.2.1), each with 1Gbps port and 100TB bandwidth per month. Right
now each server is consuming 10~12 bandwidth per day and we're going to run
out of bandwidth on coming last days of month. However we limited every
connection to 180k, you can see limit_rate 180k; in nginx.conf file.

I am newbie to this field. Please correct me if i didn't satisfy your
question regarding bandwidth. :)
