asked on Traffic Analyzer
I am experiencing heavy bandwidth utilization in my internet circuit and file download speed is very low due to heavy traffic. Which is the best tool to find the detailed traffic flow of the specific port in the switch/firewall/router?.

what kind of router/switch. I would say ideally netflow would be the way to go, but you have to be able to get the data, the other option is wireshark

I have cisco 4500 series switch and ASA 5520 firewall
so I would go netflow on either the switch if you are running layer 3 on it or the asa. Check ManageEngine.com for their netflow analyzer. You could also use ip flow top-talker to see the which device but no protocol info. Somethings that is quick as you know what your servers run if they are causing it, like a backup job or something.
You can use a show connections and look for one with alot of bytes transfereed
