What is the procedure of bandwidth calculation?

Question

I am using two different hosting servers. One for the website which is shared one and another one is dedicated where all my images are hosted.
My shared hosting website pull the images from the dedicated server.
The problem I am facing is the too much usage of the dedicated server's bandwidth.

The problem we are facing is that the bandwidth of our dedicated server is increasing rapidly.

Thus I want to know how the bandwidth is calculated. For example, if my shared server (website) is hosted on USA and dedicated server(Image) is hosted somewhere in UK.

In the above senario if the customer checks or views our website it would first go to our USA server (shared) then our shared server would contact our dedicated (image server).

In the above senario how the bandwidth would be calculated will the bandwidth calculation of our dedicated server inlcude the total bandwidth usage from the visitor to the shared website and bandwidth usage of shared website to the dedicated server.

Or

The bandwidth usage of the dedicated server would include only the bandwidth used to interact between the shared server and dedicated server.

I would very gratefull if some could give relevent answer to the above queries of mine ASAP.....

Answer 1

Answer is easy,
Contact your host and ask them how they calculate it.

if it's so many megs/month limit, then it's easy, they add up how many bytes of data have been downloaded from your site.

Answer 2

You can't calculate this information by yourself. You need to talk to the hosting service to ask them what is their bandwith, if they limit yours, if you have a quota on how much you can use.

Some hosting services will have a page that gives you some statistics on their servers and sometimes how much bandwith they have allocated to your site, and how much you have consumed (total # bites per month).

To take care of this problem you should host your site on your own DSL/Cable line. Now a days the bandwith is very decent for most things you run on a web server.
