We have 20 MBPS Internet lease line, suddnly my bandwidth utilization reached peak that causes slowness of internet.
I am not able to trace whether the problem is and what should I do?
Please assist me.
You should capture all network traffic from your internet connection to understand what traffic is causing it. Until you know what causes it, you cannot take effective action to stop it happening.
There are various ways of performing the capture but they depend on your specific network hardware and toplogy.
