What are networking fundamentals, and why are they important? Join us for this repost of a classic Hedge discussion with Ethan, Eyvonne, Tom, and Russ.

What’s the deal with SONiC? Is it easy to build and use, or hard? Is it something you should be looking at? Jeff Doyle joins Russ and Tom to look at the SONiC operating system, ecosystem, and deployment.

It’s episode 300, and it’s roundtable time. In this episode, Tom, Eyvonne, and Russ talk about how systems can be designed to prevent injection attacks, and then the perennial unpleasantness of layoffs.

As we discussed in the prior episode, the 6G hype is building. What’s in 6G, though, and how realistic is it that a new wireless technology is going to radically change the world? In this episode of the Hedge, George Michaelson joins us from Australia to discuss the ins and outs of 6G.

It’s 2026, and it’s time for a new cellular telephone hype cycle: 6G! Doug Dawson from CCG joins Russ and Tom to talk about why 5G is really 4.5G, the proposed changes for 6G, and the challenges higher frequency ranges and bandwidths face in the real world.

Has MPLS really “died” because of SD-WAN services? Scott Robohn joins Tom and Russ to talk about the past and future of MPLS.

AS-SETs (not that kind) were originally designed to simplify filtering at eBGP peering points–but they seem to have gone horribly wrong. Job Snijders and Doug Madory join Tom and Russ to discuss the history, use, problems, and (hopeful) demise of AS-SETs.

Is there an interaction between Moore’s Law and network computing? If so, what is the relationship? How do advances in silicon capabilities and network speeds and feeds rely and drive one another. Geoff Huston joins Russ on this episode of the Hedge to look at a bit of the history.
