IPFIX Flow Direction and Packet Counters

July 8, 2015

In the world of NetFlow and IPFIX, flow direction is a topic that can confuse some of the best technical minds. It is an important concept in relation to routers because where information (e.g. byte counters) is gathered can have a significant impact on perceived accuracy.  This is sort of 3 part blog.  Although it isn't totally necessary, it might help the reader to understand a different type of flow directionality first as posted in my other blog.

NetFlow Calculator for Supermen!

June 4, 2014

When sizing a NetFlow or IPFIX collection appliance, many consumers go looking for a NetFlow calculator.  In order to do some calculations, you'll need to have some numbers handy. For example, what volume of flows per second can all of the hardware combined generate?  This is an important question because it will likely influence the type of collector your team invests in.

A software based collector should be able to scale to well over 40,000 flows per second which is over a couple million flows per minute.  A hardware based solution should scale to well over 100,000 flows per second.  If the solution can be distributed, collection rates well into the multi millions, should be attainable.  The problem that customers need to be aware of is that flow volume is not always directly related to bandwidth consumed.
