Interop: Firewalls, Booth Babes and Unicorn Poop
Now that I’ve returned from the whirlwind that was Interop Las Vegas, I thought I’d share some thoughts about my experience as a speaker and attendee. First the good: The UBM staff was awesome and I appreciated the chance to pontificate on one of my favorite subjects, firewalls. Thanks to some quick thinking by the […]

Identifying Introverted Tendencies
It’s no secret that our industry is full of those with interesting eccentricities. These characteristics are found in varying degrees with those we come into contact with daily. The extremes of these often manifest themselves as a general perception of those in technology. This even happens as technical characters are portrayed television. One example of this […]

Book Review: A Primer of Multicast Routing
I was recently in need of a refresher on multicast routing, so I picked up Eric Rosenberg’s A Primer of Multicast Routing (Springer Briefs in Computer Science). The overall plan of the book is excellent, starting with a basic overview of what multicast is (and does), including why multicast is more efficient than unicast for […]

Getting the Most Out of SPAN or Mirror Ports
In my previous blog post I looked at the benefits and limitations of SPAN ports. SPAN or mirror ports are a convenient way of getting access to network packets without having to be inline like a firewall. Once you have got your network packet source in place, the next question is, what applications are available […]

Are You a Fuddy Duddy?
This recent article from IEEE Spectrum discusses our impression that as we age, we lose the ability to learn quickly — fluid intelligence, as it’s called. An accompanying chart shows this in some degree through the skill of chess players across a range of ages. There’s something suspicious about this chart, though, and it’s pairing […]

Machine Fragile: More Thoughts
I just ran across a pointer to this research on Bruce Schneier’s blog: Networking system components that are well-behaved in separation may create counter-intuitive emergent system behaviors, which are not well-behaved at all. For example, cooperative behavior might unexpectedly break down as the connectivity of interaction partners grows. “Applying this to the global network of […]

The Technical Mind
I have worked in technology full-time for nearly fifteen years. Prior to this, I built PCs and was somewhat of a technical hobbyist. Occasionally, I am faced with the question, “How does one get into computers?” or “How can I get into computer networking?” There are many paths and correct answers to these questions. The […]

VMware VCDX Lab: The Hardware
I have to admit I’m a big VMware fanboy. Wanting to master the art of virtualization, I’ve set out to build out a personal lab. My primary goal is to work my way up to the VCDX certification. The curious thing about building a VMware lab is that all parts need to be on the […]

A Data Center Delivers Apps – So Shouldn’t We Monitor App Delivery?
Dinner with His Toadishness, Derick Winkworth, the other night rolled into a 3+ hour discussion of avant garde ways to do networking. One of the adjunct topics that came up was that of ownership within IT. Ownership is a complex problem in the data center, because there’s many complex technologies at work. No one single […]

Machine Fragile
Yesterday, a “breaking news” tweet at 1:07 PM EDT from the Associated Press reported that two explosions had occurred at the White House and President Obama had been injured. The news immediately sent the Dow Jones Industrial Average down 143 points, as this graph at the London Telegraph shows. There’s also a lovely animated display […]

It Works and It Should Be Better
You say, “It works – don’t fix it.” I hear, “It works – don’t touch it.” I’m also thinking that if you don’t touch it, then it’s never upgraded or changed. Is a static, unchanged network the best you can do to support your business ? Are you happy with just doing more of the same […]

Your Job Hunt is YOUR Responsibility
Earlier this week, I read the article below. This article took a strong stance that a recruiter works for the employer, not those seeking employment. I think there are some valid points made. However, my views are a little less extreme than that of the author. NEWSFLASH: A Recruiter is Not a Job Finder!. Frankly, […]

What The Heck Is F5 Networks’ TMOS?
F5 Network’s Traffic Management Operating System (TMOS) is, first and foremost and for the sake of clarity, NOT an individual operating system. It is the software foundation for all of F5’s network or traffic (not data) products; physical or virtual. TMOS almost seems to be a concept rather than a concrete thing when you first try […]

Show 144 – Open EIGRP with Russ White + Cisco’s Donnie Savage
EIGRP is a distance vector routing protocol that for many years was unique to Cisco networking environments. Created and championed by Cisco, it didn’t get any traction in the standards bodies in the early days, because there were already enough interior gateway routing protocols around according to some. EIGRP just didn’t interest enough of the […]

Cisco Nexus – Port “Inactive” Status
Quick notes on the “inactive” port status seen on the Cisco Nexus platform, which was perplexing the first time I ran into it. This isn’t a new status, existing on a variety of Cisco platforms for a long time now. As it happens, I’ve just not seen it that often historically. In dealing with the […]
