The most advanced Flow technologies today come in the form of (FnF) Flexible NetFlow Reporting and IPFIX Reporting.  Some vendors have renamed these technologies to AppFlow, Cascade Flow, J-Flow and NetStream, however they are usually a near copy of either NetFlow or IPFIX.

Palo Alto Networks NetFlow support is coming soon and we’ll be one of the first vendors to support it in our NetFlow Analyzer.  The team at Palo Alto Networks not only supports traditional NetFlow, but they also support deep packet analysis to identify actual applications such as Skype, BitTorrent, Webex and more.  Many netflow analysis tools mistakenly identify this traffic as HTTP (TCP 80).  Cisco NetFlow NBAR is a similar technology which makes network traffic monitoring much more informative especially when trying to perform root cause analysis. This feature is not in the Cisco ASA NetFlow export.

Vyatta NetFlow has been improved in some of the latest VC 6.x releases. I worked on a NetFlow reporting issue with a VC 6.0 user in the past trying to figure out why his NetFlow Analyzer was not showing the expected amount of traffic. We used Wireshark and found that a large number of flow packets were being exported without flow data, therefore were useless and discarded by the collector. Since he upgraded to VC 6.2, he was able to see all his traffic. Vyatta now supports MAC addresses, as seen in the image below! Read more »
