Is the Cisco proposed standard for IP Flow Information eXport and was designed based on NetFlow v9. Several vendors have already adopted IPFIX (e.g. Juniper, Avaya, SonicWALL, nBox, etc.). It added support for variable length strings. In the future, Cisco will release Application Visibility and Control (AVC) exports which will take advantage of the variable length string capability and export HTTP host (E.g. netflix.com, youtube.com, facebook.com, etc.).
