Hi,

You need have a tool like NetFlow Analyzer to analyze the bandwidth.
This will analyze the bandwidth utilization on the link and give you in a graph like utilized up to 40% or 50% like that and also what all the source and destiantion address usage report per application wise.

You can download the trial version which valid for 30 days.
