Bandwidth monitor

This is more of a “Have you seen this?” than a tech question.

A year ago, my old boss used a pretty cool bandwidth monitor.
On the center of the screen was a green circle. On the outer right of the circle were listed the IP addresses of the servers. The left side was the clients or any system getting a resource (listed by IP as well). Green lines running accross the circle (from the client IP to the server IP) would show where a connection was taking place. The thickness of the line determined how much bandwidth was being used.

If anyone has seen this I would like to know!
🙂 I do not the name of the company that makes it or the program name.
