NetFlow is a simple, effective way to increase visibility into traffic types and usage patterns across systems. The flow-generated data can be used to build relationships and usage patterns between nodes on the network. Routers and switches that support NetFlow can collect IP traffic statistics to be exported as NetFlow records. However the processor and memory load of enabling NetFlow can cause service degradation and affect their ability to pass traffic without introducing latency and packet drops. Due to this processing overhead, sampled NetFlow is implemented in most of the high-end routers. Sampling one in every "n" packets for NetFlow processing can severely limit the visibility needed to monitor flows and fail to provide a comprehensive network trend analysis.
