Hi,
At times, the internet slows down drastically. Here are a few quick questions. If the internet goes, that has nothing to do with the performance of the network? Correct. Since the internet is slow, how can I find out where the traffic is coming from? As in, whos downloading 10 GB of music? Thanks
How you hunt down the bad traffic depends on which equipment you have.
1) You could install wireshark on a pc and mirror traffic in a switch to that pc.
2) If you have control of a router in the path you can have that router sending netflow messages to a netflow collector.
3) You firewall might have built in logs of the traffic flows.
