SELECTING THE RIGHT BANDWIDTH

It's hard to make a recommendation based on the information you provided. The statistics only show what percentage of your traffic was used by which service. It doesn't show the total volume of traffic.

The "How much bandwidth" question isn't enough. You also have to ask "How long is too long?"

For instance, a fair portion of your traffic is email and web browsing. Unless your users regularly send or receive large attachments a slower link might not affect them much. Similarly, a slower link would make web browsing a little more sluggish.

Be careful not to choke your web server, however. Many clients judge your company's technical prowness based on their web site! (If they can't even run a decent web server, why should I trust them with my business...)

You first step should be to moniter peak usage rates. Then, evaluate the "how fast is fast enough" question. Be sure to test thoroughly before you commit to a slower link.

Contact your service provider and they
should be able to provide you with a
history of bandwith usage over a period of
time. If not ask if they can set up a monitor
of services and provide you with this
information over a week or so. You are
interested in only the peak usage and
how long you stay there. They should be
able to give you actual bandwith usage.
Any provider worth their salt can give you
this information.
If you are breaking out of your bandwith or
using 80% for extended periods of time it
is time to look at an increase. Keep a
20% headroom over current usage.

Good luck
