William Swansen

"NetFlow is an open but proprietary network protocol created by Cisco Systems. It collects active IP network traffic as it flows in or out of an interface. Data collected by NetFlow is analyzed to understand network traffic flow and the volume of data transiting the network. I use NetFlow protocol as a network traffic analyzer to determine the point of origin of data packets, their destination, the overall volume on the network, and the paths the data takes."
