# Calculation

Mar 17th, 2008

Need to do calculation based on the below inputs.Pls Suggest me for how much bandwidth link i can go for to upload the documents??

Per Doc : 900kb

Per day : 6GB

Hi, You can go for 640,000 bps link to upload your GB, which will take 22 hrs, 22 mins, 10 secs, with out any payload. It has calculated 6GB/day. Thanks Goutam.

Hello,

total data = 6GB = 6 * 2^30 bytes = 6 * 2^30 * 8 bits = 48 * 2^30 bits

total duration = 24 h = 24 * 60 * 60 seconds = 86400 seconds

(48 * 2^30 bits)/(86400 seconds) = (almost) 600000 bps = 600 kbps

This the pure bandwidth for the documents. It does not iclude network layers overhead.

Maybe if we add another 100 kbps to make it 700 kbps, you will be ok (just an estimate).

Kind Regards,

M.

Hi Nasheer, You don't mention the duration properly. Per day = 24 hrs? Or the total amount of data (6GB) you want to upload ?

That means 1 MB link is enough. am i right.

Hello,

Yes, 1 Mbps link is fine.

BTW, when we refer to network speeds we write 1 Mbps (which is 10^6 bps). When we write 1 MB, then 1 Mbyte data is implied (which is 2^20 * 8 bits).

Kind Regards,

M.
