I currently run a network of 35 people. I have a 1MBPS clear-channel connection with my provider. My provider gave me a link to monitor the connection usage. Since last week, it shows the network is overloaded, and of course all network services like web browsing, smtp, pop3, .. are experiencing latency.
I was wondering if there is a good, low budget tool to analyze network traffic and determine which computers are causing the most traffic? We don't have budget for a very expensive tool.
Thanks a lot!!
