Hedge 110: Andrew Alston and SRv6 Security
SRv6, a form of source routing, is the new and interesting method being created by the IETF to allow traffic engineering and traffic steering. This is not the first time the networking world has tried source routing, however—and in the spirit of rule 11, we should ask some questions. How and why did source routing fail last time? Have we learned those lessons and changed the way we’re doing things to overcome those limitations? Security seems to be one area where problems arise in the source routing paradigm.
Hedge 109: Edward Lewis and the DNS Core
What is the “core” of the DNS system, and how has it changed across the years? Edward Lewis joins Tom Ammon and Russ White to discuss his research into what the “core” of the domain name system is and how it has changed—including the rise of the large cloud players to the core of the default free zone.
Hedge 108: In Defense of Boring Technology with Andrew Wertkin
Engineers (and marketing folks) love new technology. Watching an engineer learn or unwrap some new technology is like watching a dog chase a squirrel—the point is not to catch the squirrel, it’s just that the chase is really fun. Join Andrew Wertkin (from BlueCat Networks), Tom Ammon, and Russ White as we discuss the importance of simple, boring technologies, and moderating our love of the new.
Hedge 107: Career Advice with Terry Slattery
Whether you’re just starting in your technology career, or you’re an old hand who likes to go back to basics and understand how to move forward in your career, this episode of the Hedge is for you. Terry Slattery joins Tom Ammon and Russ White to discuss the things you can do to build a successful career as in the world of network engineering.
Hedge 106: Compositional Network Modeling and Zen
One topic of constant discussion among network engineers is the basic problems surrounding network modeling, which leads to configuration, telemetry, and troubleshooting. In this episode of the Hedge, Ryan Beckett, Tom Ammon, and Russ White discuss Zen, a general framework for compositional network modelling.
Hedge 105: Johan Gustawsson and Changing Provider Architectures
Many service providers have the feeling that they “didn’t do anything wrong, but somehow we still lost.” How are providers reacting to the massive changes in the networking field, and how are they trying to regain their footing so they can move into the coming decades better positioned to compete? Join Johan Gustawsson, Tom Ammon, and Russ White as we discuss the impact of merchant silicon and changing applications on the architecture of service providers.
