The ng_netflow node implements Cisco's Netflow (c) version 5 protocol on router running FreeBSD. ng_netflow listens for incoming traffic and identifies unique flows in it. Flows are distinguished by endpoint IP addresses, TCP/UDP port numbers and ToS. Expired flows are exported out of the node. All operation is done in kernel: both traffic capturing and export datagram generation. Exported data contaion almost all Netflow version 5 fields, except of AS numbers.
