Geek’s Guide to NetFlow v9 Datagram
Network traffic monitoring is a critical component of an overall network management framework and one of the most common ways to monitor network traffic is through the analysis of flow data. By analyzing flow data, a picture of network traffic flow and volume can be built. In other words, where the traffic is coming from, where it is going to, and how much is being generated. Read this whitepaper for a basic understanding of how flow technology works, specifically Cisco’s NetFlow v9, what metrics are being captured, and how they are interpreted.
