Bandwidth in 100 mbps

BlueSpirit · 01-03-2012, 04:31 PM

Hi,

I was wondering. When dedicated server providers give a 100mbps dedicated port, they also state that "unmetered bandwidth" gives approximately 32TB max of bandwidth.

How does those calculations are done?
If you go in the google calculator here it gives me 32 101.3651 GB/mo.

I thought it would be done this way
(100 mb/s * 3600 s/hr * 24 hr/day * 31 day/mo)/(1048576 gb/tb) = 255TB

How come a 100mbps dedicated port gives 32TB of maximum theoritical bandwidth?

Thanks alot!

that's probably the monthly traffic, and then it's simple maths.
Bear in mind that a day has 86400 seconds, a month has 30 days (just for the sake of simplicity).
That yields

100Mb/s * 86400s * 30 = 259'200'000Mb (about 259 Tb)

Note that we're still talking bits here, not bytes - hence the lowercase 'b'.
Now divide your 259Tb by 8bits/byte, and you get roughly 32TB (uppercase 'B' indicates bytes instead of bits).
