NetFlow analyzers vs. packet analyzers - are really complementary technologies. For years NetFlow has been a valuable tool used to suppliment the use of packet analysis; and to a certain extent that is still the case.

With the barrage of applications today sharing similar behavior characteristics at the protocol level, it becomes necessary to take deep packet inspection steps to determine what the actual application is that is causing the traffic.  Thankfully, Cisco already does this for us with something called Network-Based Application Recognition (NBAR) .   We explained NBAR support in a recent blog and how it allows us to improve on network traffic analysis.

Plixer International, developers of a market leading NetFlow and sFlow analysis tool set, today released Scrutinizer NetFlow & sFlow Analyzer version 7.3, bringing network traffic analysis software to the next level.

With the latest release of their NetFlow analyzer, Plixer has introduced several new report types, including NBAR reports. Cisco’s NBAR technology does deep packet inspection into the traffic moving through the router to identify the applications being used by hosts. For example; H323, Telnet, RTP, Exchange and Skype are identified and exported in NetFlow.

“We feel, and have felt for some time, that Flexible NetFlow has the potential to expand greatly on the level of information that can be reported on by standard NetFlow,” says Plixer CTO, Marc Bilodeau. “With Scrutinizer NetFlow & sFlow Analyzer version 7.3, Plixer is leading the pack in not only the adoption of Flexible NetFlow, but in the implementation of its key advantages over other versions of NetFlow.”
