The light at the end of the fiber is an oncoming train! (by Jim MacLeod)

The light at the end of the fiber is an oncoming train

There’s a potential problem looming with “always-on” packet capture: bandwidth is growing faster than processing power.  In this article, I’ll look at the trends that show the upcoming doom, as well as potential ways to avoid the problem, assuming that we re-think when and how to do packet capture.

The setup

The purpose of always-on capture is to record all packets on one or more links as insurance against problems.  This technique is especially valued in network security, to answer the questions of “how did they get in” and “what did they do.”  On TV cop dramas, they review the security camera footage; on a network, they review the packet capture.  To protect against dropping packets, many appliances include “capture cards” – but regardless of the appliance, all real-time analysis happens in the CPU, and that’s going to become a problem.Train of light

The numbers

Moore’s Law predicts that CPU power can double every 18 months.  That growth enables each new appliance to capture and analyze more traffic.  More traffic also requires more storage.  Kryder’s Law estimates that storage density doubles every 12 months.  The problem is that traffic speed grows faster than either CPU or storage: Butter’s Law of Photonics observes that optical network capacity can double in only 9 months.

Live Demo @ LMTV | Omnipliance WiFi from WildPackets (by Jay Botelho)



Live Event Time: Wednesday, November 19, 2014 - 9:30 AM PST


Wildpacket_170With organizations rapidly transitioning to 802.11ac, wireless network data rates can now easily exceed 1Gbps, and speeds are only increasing as we go to Phase 2 and beyond. These speeds exceed the capabilities of traditional portable WLAN analysis and freeware.

Multi-gigabit WLAN analysis requires a new approach.

Join us as +Jay Botelho presents the capabilities of a new WLAN analysis appliance from +WildPackets, the Omnipliance WiFi, designed to meet the needs of today’s advanced wireless networks.

LMTV | Are You Ready for 802.11ac? (by Jay Botelho)



Live Event Time: Wednesday, November 5, 2014 - 9:30 AM PST


Wildpacket_170The new IEEE 802.11ac standard is changing the rules when it comes to WLAN troubleshooting based on packet capture and analysis. No one disagrees that packet-based analysis is the most complete and most accurate when it comes to WLAN troubleshooting, but the software, equipment, and processes required to perform packet-based analysis are being challenged by 802.11ac.

  • Data rates can now exceed 1Gbps – Can your analysis software keep up?
  • Access points are already at 3-stream – Is your monitoring system equally capable?
  • You now have WLANs deployed across the enterprise – How do you deal with problems that are thousands of miles away?


This week +Jay Botelho of +WildPackets will discuss a solution to address these and many other concerns with the migration to 802.11ac.

Survey Says: Need More Network Forensics and Real-Time Visibility at 10G! (by Jay Botelho)

WildPackets launched a 2013 State of Faster Networks survey back in July of this year with the goal of determining exactly how widespread companies’ migration to 10G is and what kinds of problems are being seen along the way.

Over the past few months we compiled the responses in our report The State of Faster Networks. Hopefully they will help shed some light on how you can fully utilize, and transition to, faster networks.

Who Took the Survey?

We received responses from more than 100 network engineers and IT directors, and as you can see, the majority of respondents are already supporting 10G networks.

Take Our Survey to Help Our Community and Win a $50 Gift Card (By Jay Botelho)



10G is here.

Industry reports vary widely on the footprint of 10G. WildPackets wants to get to the bottom of this and to determine exactly how widespread the 10G migration is, and what kinds of problems are being seen along the way.

Please click to take our survey. The findings will be shared on LoveMyTool. We will be giving away a $50 Amazon gift card to two lucky survey respondents, so please take just a moment to help our community to uncover the real story on 10G.


Network Monitoring on High-Speed Networks (by Jay Botelho)




While most enterprises are making the jump from 1G to 10G, some early adopters are leaping ahead to 40G and even 100G. These rapid advancements in networking, along with new technologies like virtual networks and software defined networks (SDN), are driving an equally large change in network monitoring technologies.

The ability to seamlessly monitor, analyze, and troubleshoot, especially in real time, at multi-gigabit speeds is becoming a significant challenge. However, there are some ways to make this process more manageable and ensure that you are not missing the data you need for detailed network analysis.


Prioritize Monitoring Needs

Let’s say your 10G link (full duplex) is 50% utilized. That’s 10Gbps of traffic that requires analysis, or about 77GBytes of data that must be analyzed per minute. Besides supercomputing applications, like weather predictions, there are very few applications that require this level of data processing. And of course super-computing platforms are not within the budget for most network analysis solutions, so all this analysis must be packed into more traditional and affordable computing platforms.
