See in the Fog with Ixia CloudLens

Imagine looking up toward the sky on an average afternoon, marveling at the piercing blue background salted by white fluffy clouds. Each cloud is uniquely shaped, gloriously afloat, describable in terms even a five-year-old can understand. They look dense enough to stand on, soft enough to sleep on, and righteous enough to spend an afterlife walking among.

Now imagine riding passenger on a Boeing 747. You’re peering out the window as the aircraft takes off. As you ascend, steadily approaching the definitively shaped clouds, they curiously begin to lose shape and opacity. Enter the clouds — your perspective has significantly changed, for you can no longer see them for what they are. Rather, the sky is whitewashed and borderless. Oddly, you may still be able to see others in the distance, but you’re essentially blind to the cloud you’re in. Often times all you’ll see is the giant white soul of the cloud with no sky whatsoever, no coherent shape or texture. (more…)

My thoughts on Paessler may surprise you

Ever hear of a company called Paessler AG? No? Neither have I. Ever hear of a product called PRTG? Of course?! Me too! Call me crazy, but I never knew this was the same company! Paessler AG presented for Tech Field Day at VMworld in Barcelona yesterday, demonstrating their product PRTG and making legitimate points in support of their competitive edge in the monitoring industry. In this blog I’ll be doing a personal Q&A about PRTG, running queries against the DB (Dave Brain), hoping it doesn’t fail on me. If it fails, I’m not too concerned, for I’ve installed the appropriate SNMP MIBs used to alert my right hand that coffee needs to be delivered to my mouth. PRTG, save me! (more…)

Fireflies, Synchronicity and SD-WAN

Imagine a warm summer night away from the city hustle and techno grind. Moon is new, sky is clear, air is crisp, mind is easy. Peering out towards a bank of pines that border the woodland, you notice a few fireflies start to flash their bulbs. Your eyes are opened wide, equipped like a sharp shooters, honing in on the next flash. More start to blink into existence, matching the rhythmic nature of the others that have already joined the mantra. It’s as though an endless number of blinking fireflies are entering the night, breathing in epic unison.

ONUG – What is it, and why am I here?

If you’ve ever seen a film with audio engineering by THX, you’ve experienced that brief, immersive surround sound that captivates your senses, completely eradicating your thoughts while the mind basks in weightless bliss.  Much like the beginning of a George Lucas film, the networking industry is currently in a state of THX, steadily swelling with that warm buzz, fantasizing about the potential for bliss.  Software-Defined Networking (SDN), Software-Defined WAN (SD-WAN), Network Function Virtualization (NFV), Hybrid Clouds, Virtual Overlays and Containerization are at the crest of this tsunami of change, promised to radically disrupt the way businesses develop and operate their networks. But change is risky, especially in regards to bleeding technologies. Companies need better opportunities to understand their options and share experiences with each other.  Enter ONUG.

802.11ac Wave 2, MGig and Cisco’s 2800 & 3800 Series Access Points

Several weeks ago I attended a presentation on Cisco’s new 2800 and 3800 Series access points.  I’m quite impressed with some of the new capabilities these APs bring to the market.  The presenters, Mark Denny and Brian Levin, were passionate regarding the implications this has for wireless networks.  I felt I needed to take a step back to really understand why some of these enhancements and new features are so important to wireless infrastructure.  I’ll run through a few of the capabilities that I personally feel are most significant.  I’ll attempt to keep it concise.

The roof, the roof, the roof is on IP

What is Digital Ceiling?

Looking back at the evolution of the network in the past decade, we see a constant trend of devices migrating to Ethernet, resulting in a migration to IP. IP telephony took off in 2005 and is now the de facto standard for any phone system. Coax-connected cameras migrated to IP surveillance in the late 2000s. Legacy building management systems using BACnet started migrating to low-voltage PoE systems in the early 2010s. Within the past year, we’ve seen a new trend of high-voltage systems like lighting start migrating towards low-voltage PoE, dubbed “Smart Lighting”. This move towards digitization makes sense on all fronts. It’s cheaper, scalable, extensible, can easily be managed and monitored, and opens the door for new experiences with intelligent buildings.

Cisco Linguistics & The Grumpy Old Router

Traveller

I’m a first time traveler to another country. I’m aware of multiple languages, but I don’t know how to speak any other than English. It’s one of those things that I’ve always wanted to learn, but just never got around to. So, I’m aboard an aircraft to Germany, and the first conversation I had on the plane was with a flight attendant. It went a little something like this:

Her: Ist das Ihre rote Tasche dort?
Me: … <wishing I knew what she was saying>
Her: …
Me: English?
Her: Is that your red bag over there?
Me: Nein

It started out weak and embarrassing, I didn’t know what she was saying. There was a very brief moment, just a second or two, where my brain was attempting with futility to decipher the foreign tongue, returning a meandering blank stare, followed by the simple one-worded question: “English?”. The flight attendant immediately responded in my native language, and I clearly understood her. I responded confidently with a German “nein”. She smiled. (more…)
