Softflowd is a flow-based network traffic anaylser capable of Cisco
Netflow data export. Softflowd semi-statefully tracks traffic
flows recorded by listening on a network interface or by reading a
packet capture file. These flows may be reported via NetFlow to a
collecting host or summarised within softflowd itself.
