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.
Hedge 104: Automation with David Gee
Automation is often put forward as the answer to all our problems—but without a map, how can we be certain we are moving in the right direction? David Gee joins Tom Ammon and Russ White on this episode of the Hedge to talk about automata without a map. Where did we come from, what are we doing with automation right now, and what do we need to do to map out a truly better future?
Hedge 103: BGP Security with Geoff Huston
Our community has been talking about BGP security for over 20 years. While MANRS and the RPKI have made some headway in securing BGP, the process of deciding on a method to provide at least the information providers need to make more rational decisions about the validity of individual routes is still ongoing. Geoff Huston joins Alvaro, Russ, and Tom to discuss how we got here and whether we will learn from our mistakes.

Hedge 101: In Situ OAM
Understanding the flow of a packet is difficult in modern networks, particularly data center fabrics with their wide fanout and high ECMP counts. At the same time, solving this problem is becoming increasingly important as quality of experience becomes the dominant measure of the network. A number of vendor-specific solutions are being developed to solve this problem. In this episode of the Hedge, Frank Brockners and Shwetha Bhandari join Alvaro Retana and Russ White to discuss the in-situ OAM work currently in progress in the IPPM Wg of the IETF.
Hedge 100: Supply Chain Diversity with Brooks Westbrook and Mike Bushong
Most network engineers don’t spend a lot of time thinking about their supply chain—you must call your favorite vendor, order, and a few weeks later the hardware shows up on your loading dock. It’s not so simple any more. If you disaggregate, you need to manage your software and hardware supply chains separately. You need to think about security in your supply chain—is that software package backdoored? Moving to the cloud might seem to solve these problems, but they don’t. Even virtual networks have physical limits.
Hedge 99
Two things have been top of mind for those who watch the ‘net and global Internet policy—the increasing number of widespread outages, and the logical and physical centralization of the ‘net. How do these things relate to one another? Alban Kwan joins us to discuss the relationship between centralization and widespread outages. You can read Alban’s article on the topic here.
Hedge 098: DRIP with Stuart Card
Drones are becoming—and in many cases have already become—an everyday part of our lives. Drones are used in warfare, delivery services, photography, and recreation. One of the problems facing the world of drones, however, is the strong tie-in between the controller and the drone; this proprietary link limits innovation and reduces the information available to public officials to manage traffic, and even to protect the privacy of drone operators. The DRIP working group is building protocols designed to standardize the drone-to-controller interface, advancing the state of the art in drones and opening up the field for innovation. Stuart Card joins Alvaro Retana and Russ White to discuss DRIP.
Hedge 97: Low Context DevOps
Language is deeply contextual—one of my favorite sayings from the theological world is if you take the text out of its context, you are just left with the con. What does context have to do with development and operations, though? Can there be low and high context situations in the daily life of building and running systems? Thomas Limoncelli joins Tom Ammon and Russ White to discuss the idea of low context devops, and the larger issue of context in managing projects and teams, on this episode of the Hedge.
Hedge 96: Mark Nottingham and the Future of Standardization
It often seems like the IETF is losing steam—building standards, particularly as large cloud-scale companies a reducing their participation in standards bodies and deploying whatever works for them. Given these changes, what is the future of standards bodies like the IETF? Mark Nottingham joins Tom Ammon and Russ White in a broad-ranging discussion around this topic.
