Hi Gopal

You need to consider the concurrency usage ratio in your local lan based on which you can determine the bandwidth to be subscribed from your SP..

You also need to check out whether upload or the download traffic will be there if in case if you are going for Asymmetrical line..

Best practice also would be to subscribe for lesser bandwidth for short duration and observe the peak/average usage on the links and based on that you can decide the actual bandwidth requirement for your facility..

There are other factors like latency which you may look in if you are establishing some kinda ipsec tunnels over the bandwidth that too again will consume bandwidth.
