I’m sitting with Jeff Doyle and Jeff Tantsura to talk about network complexity on the Between 0x2 Nerds podcast today at 1PM ET today. The link is here—
Join us if you can.
My article on Internet centralization just published over at The Public Discourse—
Most of the Internet’s traffic now flows through the networks of a few large companies rather than a multitude of small transit providers, and the Internet’s physical infrastructure is being reshaped to meet this new reality. But relying on a few providers to host all the content on the Internet makes it possible for just a few companies to shut down entire services or control speech.
On the 28th—in two days—I’m doing a master class over at Juniper on DC fabric disaggregation. I’ll spend some time defining the concept (there are two different ideas we use the word disaggregation to describe), and then consider some of the positive and negative aspects of disaggregation. This is a one hour session, and it’s free. Register here.
A couple of weeks ago, I joined Leslie Daigle and Alexa Reid on Techsequences to talk about free speech and the physical platform—does the right to free speech include the right to build and operate physical facilities like printing presses and web hosting? I argue it does. Listen in if you want to hear my argument, and how this relates to situations such as the “takedown” of Parler.
Those who follow my work know I’ve been focused on building live webinars for the last year or two, but I am still creating pre-recorded material for Pearson. The latest is built from several live webinars which I no longer give; I’ve updated the material and turned them into a seven-hour course called How Networks Really Work. Although I begin here with the “four things,” the focus is on a problem/solution view of routed control planes. From the description:
There are many elements to a networking system, including hosts, virtual hosts, routers, virtual routers, routing protocols, discovery protocols, etc. Each protocol and device (whether virtual or physical) is generally studied as an individual “thing.” It is not common to consider all these parts as components of a system that works together to carry traffic through a network. To show how all these components work together to form a complete system, this video course presents a series of walk throughs showing the processing involved in various kinds of network events, and how control planes use those events to build the information needed to carry traffic through a network.
This course is largely complimentary to the course Ethan and I did a couple of years back, Understanding Network Transports. Taking both would give you a good understanding of network fundamentals. This material is also parallel and complimentary to Problems and Solutions in Computer Networks, which Ethan and I published a few years ago.
I am working on one new live webinar; I really need to get my butt in gear on another one I’ve been discussing for a long time (but I somehow dropped the ball).
I’ve started publishing in the Public Discourse on topics of technology and culture; the following is the first article they’ve accepted. Note the contents might be classified as a little controversial.
The recent “takedown” of Parler by Amazon, Apple, and Google has spurred discussion in technological circles. Do the companies’ actions constitute an abuse of free speech? Or were the tech giants well within their rights, simply enforcing their own “terms of service”? Looking back at the history of free speech in the United States, especially the historical moment during which the right to free speech was codified, can offer guidance.
I’ll be joining Jeff Tantsura, Nick Buraglio, and Brooks Westbrook for a roundtable on March 16, 9 am PST (that’s tomorrow if you’re reading this the day it publishes) about the development of wide area networking technologies up until today. This is the first part of a two part series on changes in the wide area network.
