The Hedge 65: Jacquelyn Adams and the Future of Work
Everyone in networking—and beyond networking, in fact—thinks about what the future of work might look like. Jacquelyn Adams joins Eyvonne Sharp, Tom Ammon, and Russ White on this episode of the Hedge to discuss what work might look like based on this era of rapid change, and how you can prepare for that future.
The OSI Model: STOP IT!
The OSI model is perhaps the best-known—and perhaps the most-loved—model in the networking world. It’s taught in every basic networking course, and just about every blog (other than this one) has some article explaining the model someplace or another (for instance, here is one of the better examples).
On Important Things
I tend to be a very private person; I rarely discuss my “real life” with anyone except a few close friends. I thought it appropriate, though, in this season—both the season of the year and this season in my life—to post something a little more personal. One thing people often remark about my personality is that I seem to be disturbed by very little in life. No matter what curve ball life might throw my way, I take the hit and turn it around, regain my sense of humor, and press forward into the fray more quickly than many expect.
The Hedge 64: Brian Keys and Burnout
Burnout stalks most network engineers—and most people in the world of information technology—striking at least once in every career, it seems, and often more than once. In this episode, Brian Keys joins Eyvonne Sharp, Tom Ammon, and Russ White to discuss his personal experience with burnout. The discussion then turns to general strategies and ideas for avoiding burnout on a day-to-day basis.
Pulling Back the Curtains
One of the major sources of complexity in modern systems is the simple failure to pull back the curtains. From a recent blog post over at the ACM—
The Hedge 63: Anycast with Andree Toonk
Anycast is a bit of a mystery to a lot of network engineers. What is it, and what is it used for? Andree Toonk joins Tom and Russ on this episode of the Hedge to discuss the many uses of anycast, particularly in the realm of the Domain Name Service (DNS). Andree helped build the OpenDNS network and service, so he has deep experience with anycast routing on the DFZ.
Current Work in BGP Security
I’ve been chasing BGP security since before the publication of the soBGP drafts, way back in the early 2000’s (that’s almost 20 years for those who are math challenged). The most recent news largely centers on the RPKI, which is used to ensure the AS originating an advertisements is authorized to do so (or rather “owns” the resource or prefix). If you are not “up” on what the RPKI does, or how it works, you might find this old blog post useful—its actually the tenth post in a ten post series on the topic of BGP security.
The Hedge 62: Jacob Hess and the Importance of History
At first glance, it would seem like the history of a technology would have little to do with teaching that technology. Jacob Hess of NexGenT joins us in this episode of the Hedge to help us understand why he always includes the history of a technology when teaching it—a conversation that broadened out into why learning history is important for all network engineers.
The EXPERIENCE HAS SHOWN THAT Keyword (RFC1925, Rule 4)
The world of information technology is filled, often to overflowing, with those who “know better.” For instance, I was recently reading an introduction to networking in a very popular orchestration system that began with the declaration that routing was hard, and therefore this system avoided routing. The document then went on to describe a system of moving packets around using multiple levels of Network Address Translation (NAT) and centrally configured policy-based routing (or filter-based forwarding) that was clearly simpler than the distributed protocols used to run large-scale networks. I thought, for a moment, of writing the author and pointing out the system in question had merely reinvented routing in a rather inefficient and probably broken way, but I relented.
