Overvaluing Experience

28 June 2016 |

“Sure, great candidate—so long as you just look at the paper. They don’t have any experience.” I wonder how many times I’ve heard this in my networking career—I wonder how many times this has been said about me, in fact, after I’ve walked out of an interview room. We all know the tale of the…

Reaction: Complexity Sells

21 June 2016 |

Over at IPSpace this last week, Ivan pointed to a paper by Dijkstra (and if you don’t know who that is, you need to learn a thing or two about the history of routing protocols—because history makes culture, and culture matters—or, as the tagline on this blog says, culture eats technology for breakfast). In this…

No Capes, No Wands

14 June 2016 |

As a keen observer of the network engineering world for the last twenty… okay, maybe longer, but I don’t want to sound like an old man telling stories quite yet… years, there’s one thing I’ve always found kind-of strange. We have a strong tendency towards hero worship. I don’t really know why this might be,…

Building a “Network” Network

7 June 2016 |

Over my years as a network engineer, I’ve notice that the engineering job tends to be somewhat isolated (or isolating). Part of the reason is probably that there tend to be one or two network engineers at a single company, munged in with a lot of other IT folks who share some common ground (but…

Can != Should, Is != Ought

30 May 2016 |

Maybe I’m getting too old for my own good. Or maybe studying philosophy is making me older. Here in the US, though, it is Memorial Day, a day where people normally grill burgers and dogs, throw a few back, and forget to ask why. It’s just another day off, and days off are good for—well,…

New Ways of Thinking

27 April 2016 |

Rule 11 definitely applies to most new technology that’s being hyped (and overhyped) in the networking world. But while some things stay the same, others actually do change. From one of my readers— Much of the current “trends” in networking are largely just new marketing-speak on old concepts, but some (I’ll propose) are actually new,…

What should IETF “standard track” actually mean?

12 April 2016 |

This post is going to be a little off the beaten path, but it might yet be useful for folks interested in the process of standardization through the IETF. Last week, at the IETF in Buenos Aires, a proposal was put forward to move the IPv4 specifications to historic status. Geoff Huston, in his ISP…

Writing books still matters—reading them does, too

6 April 2016 |

Ivan, over at ipspace.net, has an interesting post up on writing books — Why would you want to write a book? If you think you’ll earn a lot of money, think twice… unless you plan to write a science fiction bestseller, Swift-for-Dummies, or 50 Shades of Something. Several points in reply… No, you won’t make…

The Candy Jar Effect

1 April 2016 | Comments Off on The Candy Jar Effect

When I first started in Cisco TAC, as a lowly grade 3 engineer taking hardware RMA calls, I didn’t know anyone. I had just moved to North Carolina, we hadn’t found a church yet, I’m not the most social person on the face of the earth (in fact, if anything, I’m antisocial), and I was…

Should Technology Mirror Business?

16 February 2016 | Comments Off on Should Technology Mirror Business?

The essence of SDN is to create a software model of the current data network business. This quantitative model is based on volumes of data: what ‘bandwidth’ resources do I have (i.e. supply), and how can I give different quantities of this ‘bandwidth’ to different users and uses (i.e. demand)? -via circleid I’ve been in…
