NetFlow v9 Overview: NetFlow basics

NetFlow v9 Overview: NetFlow basics

Welcome to the first installment of our NetFlow v9 Overview, beginning (of course!) with NetFlow basics.

What is NetFlow?

A network flow is defined as a unidirectional sequence of packets between given source and destination endpoints.  Traditional NetFlow uses a 7-tuple of source and destination IP address, transport layer port numbers, IP Protocol, Type of Service (ToS), and the input interface port to uniquely identify flows. Flexible NetFlow (FNF) is a ground-up rewrite of NetFlow which allows the user to customize the NetFlow tuple to include (or exclude) a nearly infinite amount of different fields.

Plixer's Scrutinizer Wins 2011 Golden Bridge Award for NetFlow Innovation!

What a year so far!

You know the old saying “Time flies when you’re having fun”? Here at Plixer, our developers are so freakishly passionate about creating the NetFlow architecture of the future, the years seem to pass us by like a blur.

The hard work is really paying off! Not only were we the first company to receive Cisco certification within the Systems Management technology category but, we are proud to announce that last week we won the 2011 Golden Bridge Award for NetFlow innovations!These industry and peer awards from Golden Bridge are the world’s premier business recognition program. This award is a huge accomplishment for such a passionate group of employees. To top it all off, Cisco sent us Medianet T-Shirts!

Golden Bridge AwardWith Cisco predicting by 2013 91% of all network traffic will be voice/video streams, we’ve been spending a significant amount of time focusing on the development of the many new Cisco Medianet performance monitoring reports. Scrutinizer v9.0 is just around the corner, it will be exciting to get feedback on all of the new reports we have built for Cisco Smart Logging and Telemetry, Cisco TrustSec, Performance Routing, Performance Monitoring and of course all of the new SonicWALL IPFIX support.

What is MediaNet?
Medianet is an intelligent end-to-end network that combines video technologies in the business, home and service provider networks. More than just higher bandwidth, it optimizes video and rich media traffic. Our solution was the first to report on the new metrics Cisco imbedded into Flexible NetFlow templates. Network traffic analysis with the advanced filtering in our NetFlow Management solution is further proof that our software provides the very best in NetFlow reporting. Read more »

Configure NBAR for GoogleTalk

We recently received a request from a customer looking for a way to identify GoogleTalk (gtalk) traffic.  To address this request, we first needed to learn about this protocol.  It seems that GoogleTalk uses an existing protocol called “Jabber”, which is based on XMPP.  To simplify things, Jabber uses a standard port of 5222.
