As we approach the end of 2011, I’d like to take this time to recap some major advances in NetFlow & IPFIX reporting.
Several notable NetFlow developments for 2011 from Cisco Networks are:

What is packet loss and how do I troubleshoot packet loss with NetFlow and IPFIX? I remember when I was growing up we had a satellite connection for our television and when we would get a big snow storm while watching a movie the quality would become so poor that the movie would look like the image in this post and the movie would become unwatchable. We can attribute the poor video quality to network packet loss, as it’s hard to send network traffic through a blizzard.

The need to monitor mobile phone network traffic is rising in today’s work place environment because of non-work related activity using up valuable bandwidth. With today’s, “I’ve got an app for that” craze we need a way to determine how mobile phones are impacting network bandwidth usage. Did you know that between Apple and Android’s app stores there are over 650,000 downloadable apps? Do you have the necessary tools to monitor how mobile traffic is impacting your network?

I personnally believe NetFlow v9 and now IPFIX are two of the greatest, if not the greatest, revolution in network traffic monitoring. It makes a substantial amount of usefull traffic information available to the network administrator. However, to truly take advantage of NetFlow, a software with powerful reporting capabilities is required. Today, I would like to talk about our NetFlow Analyzer data filtering capability. Read more »

I’m sure many of you are familiar with the rise in targeted attacks via the Internet. How can NetFlow or IPFIX be analyzed to detect these types of security breaches:
I started thinking about how amazon.com keeps customer credit card information. I’m sure they are under high alert for targeted attacks at all times.

Recently, Sandvine, an Internet service provider in over 85 countries, has 
published a Spring 2011 Global Internet Phenomena Report on new Internet trends which show a steady increase in the usage of on-demand applications. In North America, Netflix has become the single largest source of Internet traffic overall. These streaming applications can become a real burden when they start affecting business critical applications; this begs the question, “how can you use NetFlow to identify Netflix traffic?”

If you are a network administrator for a major retail business then you know the inherent challenge in network monitoring across many varied locations. When hundreds or even thousands of remote sites are involved, the troubleshooting process for determining outages, increased latency or various congestion issues becomes exacerbated. Adding to the complexity, sites down or on backup sometimes need to receive priority over others. That means certain outlets need to be addressed first. Typically a queue will be established based on revenue generation of each particular site. Either way, for network professionals using our NetFlow analysis solutions, critical issues become obvious when viewing the status of all sites.
Using the right flow monitoring tools can provide the insight necessary to determine what to work on first. NetFlow and IPFIX resources can compliment any other NMS systems to provide a holistic view. Metrics such as length of time down, response time, traffic volume and even sales volume all become factors when determining the overall health of a distant store. Each retail store becomes part of an overall health measurement, either regionally or company-wide.

I think exporting Multicast NetFlow should be wisely thought out when configuring Flexible NetFlow (FnF). Specifically, I’m talking about ingress vs. egress exports. I sometimes make the suggestion to export only egress with multicast flows.
Why only Egress with Multicast Flows
When exporting multicast flows with ingress only, the destination interface on most flows is reported as 0. Egress flows display the actual destination interface of multicast flows. We don’t need to export both as this will nearly double the volume of flows exported to the collector.
