t broke, donâ€Hedge 163: Netops, Mapping, and Working Hard
It’s one of those episodes where Tom, Eyvonne, and Russ just sit around and talk about the news of the day. We cover three topics in this show. The first is Netops, automation, and where this is all going. The second is on the FCC mapping process and the reality of broadband in the US. The third—perhaps a little controversial—is about IT work habits, innovation, and adding value.
Writing An IETF Draft: Formatting, Authorship, And Submissions
This series started by discussing the history of the IETF and some of the tools you might use to build submissions to the IETF process. This, the second, post, will consider document formatting and two of the (sometimes) more difficult sections of an IETF draft to fill in. Formatting Just using one of the acceptable […]

Hedge 162: Geoff Huston and Going Dark
Encrypt everything! Now! We don’t often do well with absolutes like this in the engineering world–we tend to focus on “get it down,” and not to think very much about the side effects or unintended consequences. What are the unintended consequences of encrypting all traffic all the time? Geoff Huston joins Tom Ammon and Russ White to discuss the problems with going dark.
Infrastructure Privacy Live Webinar
I’m teaching a three-hour webinar on infrastructure privacy this coming Friday. From the description—
Privacy is important to every IT professional, including network engineers—but there is very little training oriented towards anyone other than privacy professionals. This training aims to provide a high-level overview of privacy and how privacy impacts network engineers. Information technology professionals are often perceived as “experts” on “all things IT,” and hence are bound to face questions about the importance of privacy, and how individual users can protect their privacy in more public settings.
There is a recording for anyone who registers.

Hedge 160: Avishai Ish-Shalom and Jurassic Cloud
Cloud might seem shiny and new—but that’s just the way it looks on the outside. Most cloud services are still built on decades old technology, from networking to file access. Avishai Ish-Shalom joins Tom Ammon and Russ White to discuss the impact of changes in hardware on the design of operating systems, and think through how things will need to change to continue the drive for more performance.
2022 Working Environment
The change of the year is always a good time to reflect. This year I’ve made major changes in my physical environment by reshaping many of the things about this house we recently moved to in Knoxville. Besides ripping out the entire kitchen, replacing all the floors, and reworking the fireplace, it was a good chance to rethink the office I work in every day. I’m rather persnickety about the lighting, layout, and tools I use (although a lot of people still think I’m crazy for using fairly standard tools, like Word, for writing).
This is my space, pretty much—
I use an adjustable height desk where I’m either leaning or standing—if I want to sit to read something, I normally grab a tablet and sit in the red chair off to the side, or even go someplace else in the house. I prefer not to read on my main computer screen most of the time. I normally keep ambient light to a minimum, and turn my monitor brightness down to pretty minimal, as well—below 20%.
I’m currently running an LG 38in curved monitor. I don’t game, so I care a lot more about resolution than refresh rate, etc. My Continue reading
Hedge 159: Roundtable on SONiC, Antipatterns, and Resilience through Acquisition
In this last episode of 2022, Tom, Eyvonne, and Russ sit around and talk about some interesting things going on in the world of network engineering. We start with a short discussion about SONiC, which we intend to build at least one full episode about sometime in 2023. We also discuss state and antipatterns, and finally the idea of acquiring another company to build network resilience.
Hedge 158: The State of DDoS with Roland Dobbins
DDoS attacks continue to be a persistent threat to organizations of all sizes and in all markets. Roland Dobbins joins Tom Ammon and Russ White to discuss current trends in DDoS attacks, including the increasing scope and scale, as well as the shifting methods used by attackers.
Thoughts On Switch Failures
What can we learn from a Microsoft study of switch failures in its data centers? Hardware failures are more common that software failures, the law of large numbers can overwhelm your resiliency and redundancy planning, and open-source software can be admirably robust.

Hedge 157: Vendor Lock-in with Frank Seesink
Vendor lock-in has been an issue in networking for the entire time I’ve been working in the field—since the late 1980s. I well remember the arguments over POSIX compliance, SQL middleware standards, ADA, and packet formats. It was an issue in electronics, which is where I worked before falling into a career in computer networks, too. What does “vendor independence” really mean, and what are the ways network operators can come close to having it? Frank Seesink joins Russ White and Tom Ammon to rant about—and consider—solutions to this problem.
