#EngineersUnplugged S5|Ep7: How Data Becomes Information

April 16, 2014 at 10:31 am PST

In this week’s episode, Nils Swart (@NLNils) and Stace Hipperson (@stacehipperson) discuss how data becomes information via Open Daylight. Have they whiteboarded network engineer nirvana? Watch and see. More data!

This is in fact unicorns in a distance. Foiled again:

Stace Hipperson and Nils Swart own their unicorns.

#EngineersUnplugged S5|Ep6: Transactions, Apps, and the Network

April 9, 2014 at 11:13 am PST

In this week’s episode, Nathan Sowatskey and Jacoby Thwaites discuss transactions, applications, and the network: how to reduce complexity and increase compliance by changing the transaction process.

“Be careful of the unicorn.”

#EngineersUnplugged S4|Ep10: Software Defined Hype

January 15, 2014 at 8:05 pm PST

In this episode of Engineers Unplugged, Michael Letschin (@mletschin) and Hans De Leenheer (@hansdeleenheer) discuss the history behind software defined and predictions for what the future holds for applications and developers. If hardware is an enabler and not a limit, what then? How does this impact developers? Let’s listen in:

Behold the developer-unicorn: lean and mean.

HDX Blog Series #1: Why Spectrum Intelligence Still Matters

Editor’s Note: This is the first of a four-part deep dive series into High Density Experience (HDX), Cisco’s latest solution suite designed for high density environments and next-generation wireless technologies. For more on Cisco HDX, visit www.cisco.com/go/80211ac

CleanAir for 802.11ac:  Why Spectrum Intelligence Still Matters

In wireless networking and communications, as with life, nothing good comes for free. It’s well known that the primary feature of the new IEEE 802.11ac amendment is support for an 80 MHz-wide channel. The benefit of an 80 MHz channel is the potential to double usable throughput in comparison to that of 802.11n using a 40 MHz wide channel.

However, what is less well known is that a wider RF channel is also more susceptible to interference. In other words, 802.11ac devices “hear more” than 802.11n devices, primarily due to the wider channel support. It should be noted that this is not a flaw in the 802.11ac amendment, it’s simply basic communications theory.

Nevertheless, there is far more to building an 802.11ac access point than simply meeting the standard. Not all 802.11ac access points perform equally without interference. But more importantly, not all 802.11ac access points perform well in the presence of interference.

Furthermore, there is far more to deploying High Density wireless LANs than only considering the performance of individual access points. Read More »

Prepare Your Networks for High Density without Compromising on Performance

A new year means new users and new devices. More devices means more network crowding. Mobile users demand bandwidth and speed, while the network is increasingly overwhelmed by the sheer number of devices. The networks of today and tomorrow have to be ready for high client density environments.

That’s why we’ve developed the Cisco High Density Experience (HDX). I announced HDX in a blog last October with a high level look at Cisco’s answer to handling high client density environments. Each feature in the HDX solution was designed specifically to alleviate the introduction of more clients, more bandwidth hungry applications to provide an unparalleled user experience.

Starting tomorrow we’ll kick off an HDX blog series to dive deep into the four key features that come with HDX:

  1. January 8: CleanAir
  2. January 13: Turbo Performance
  3. January 27: ClientLink 3.0
  4. February 10: Optimized Roaming
