Introducing the Citizens of Tech Podcast

Citizens of Tech is not a show about gadgets and apps, at least not specifically. It’s not a show about networking. It’s not a constipated show about IT. Rather, it’s a show for nerds who like science, gaming, books, contrarian thinking, entertainment, space exploration, transportation, energy, complex world problems, and anything else that’s somehow technology-related. Sure, that might include gadgets, apps, IT, and so on, but we’re trying to appeal to a certain kind of mind — probably yours — and not a certain kind of industry.

IPv6 — Still No Love?

When IPv6 becomes a business problem, and not a technical one, it will start seeing serious adoption in the enterprise. A lack of available IPv4 addresses and expensive aftermarket pricing might start driving North America towards broad IPv6 adoption. Finally.

The Present Impact of Open Networking & Whitebox Switching

Dell is all about open networking, and several whitebox vendors had their wares on display at Interop. IP Infusion has released OcNOS, an open networking operating system with a rich feature set right out of the gate. Ethernet switching continues to change. If you are Yet Another Cisco Buyer, do you care? I think you should. There are real dollars at stake. Eventually, it gets silly and/or irresponsible to spend money on Cadillacs.

Network Engineering In A World Of Data Center Haves & Have Nots

If we assume economies of scale, eventually, it may become silly for a business to own lots of IT infrastructure. Why not lease it from cloud providers? They’ll be able to do it cheaper, and besides…they’re experts. I think it’s possible that businesses will eventually migrate most (if not all) of their applications to the cloud.

SD-WAN’s Value Prop Conundrum

My interpretation of the SD-WAN value prop can be boiled down to cost savings, simplified operations, and improved application performance over inconsistently performing WAN links. Here’s the conundrum. An engineer might instinctively recoil at this sort of value proposition.

Is Juniper The Next Cisco?

Juniper flexed its muscles at the Innovation Showcase held in March 2015. What did they talk about? What does it mean for their customers going forward? I perform an introductory analysis.

Production Designs Are Compromise – And That’s Okay

During a bout of stress & jet lag induced insomnia, I logged onto Twitter in the wee hours to see what folks were saying. I found a number of twitpisses in my timeline. Twitpisses are arguments in which people assert that Someone On The Internet Is Wrong in 140 characters or less. After said assertion, […]

The ‘Why Talented Employees Stay’ Listicle – ORLY?

I’ve seen a list entitled “Why Talented Employees Stay” floating around Twitter. The list has been bothering me, because I don’t think it’s quite…right. The list is interesting, but I don’t believe it tells the whole story. Taken at face value, I think the list could even make it more difficult to retain certain people — not less.

What is the difference between throughput & goodput?

Throughput Throughput is the rate at which data is traversing a link. For example, take a look at the virtual router output below. The throughput rate is 643Kbps in each direction.

Goodput Goodput is the rate at which useful data traverses a link. Assuming an uncongested path between endpoints, goodput and throughput will be as […]
