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…
 
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 …

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 a…

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 …

We talk a lot of about telemetry in the networking world, but generally as a set of disconnected things we measure, rather than as an entire system. We also tend to think about what we can measure, rather than what is useful to measure. Dinesh Dutt argues we should be thinking about observability, and how to see the network as a system. Listen in a…

What if you could connect a lot of devices to the Internet—without any kind of firewall or other protection—and observe attackers trying to find their way “in?” What might you learn from such an exercise? One thing you might learn is a lot of attacks seem to originate from within a relatively small group of IP addresses—IP addresses acing badly. Li…

I often feel like I’m “behind” on what I need to get done. Being a bit metacognitive, however, I often find this feeling is more related to not organizing things well, which means I often feel like I have so much to do “right now” that I just don’t know what to do next—hence “processor thrashing on process scheduler.” Todd Palino joins this episode…

The network monitoring world is rife with formats for packets being measured—every tool has its own format. What would make things a lot better for network engineers is a standard data representation for packet analysis, no matter what format packets are captured in. Jordan Holland joins Russ White and Tom Ammon on this episode of the Hedge to disc…
 
It’s easy to assume automation can solve anything and that it’s cheap to deploy—that there are a lot of upsides to automation, and no downsides. In this episode of the Hedge, Terry Slattery joins Tom Ammon and Russ White to discuss something we don’t often talk about, the Return on Investment (ROI) of automation. https://media.blubrry.com/hedge/con…
 
Many engineers just assume that secure hardware boot is, in fact, secure. How does this security work, and just how secure is it, though? David Brown joins Tom Ammon, Eyvonne Sharp, and Russ White on this episode of the Hedge to discuss the secure boot loader in some detail. For more information on the secure boot loader and IoT, see David’s presen…
 
Network engineers tend to look at the world through the lens of a single device—an individual appliance, sold by a vendor, with a well-developed CLI for configuration and maintenance. Networks, however, are the “odd person out” in the world of information technology. In the broader technology world, a stronger systems-oriented view is more common. …
 
Intentionally poisoning BGP routes in the Default-Free Zone (DFZ) would always be a bad thing, right? Actually, this is a fairly common method to steer traffic flows away from and through specific autonomous systems. How does this work, how common is it, and who does this? Jared Smith joins us on this episode of the Hedge to discuss the technique, …
 
QUIC is a middle-aged protocol at this point—it’s several years old, and widely deployed although TCP still dominates the transport layer of the Internet. In this episode of the Hedge, Jana Iyengar joins Alvaro Retana and Russ White to discuss the motivation for developing QUIC, and its ongoing development and deployment. https://media.blubrry.com/…
 
Although there are varying opinions 5G—is it real? Is it really going to have extremely low latency? Does the disaggregation of software and hardware really matter? Is it really going to provide a lot more bandwidth? Are existing backhaul networks going to be able to handle the additional load? For network engineers in particular, the world of 5G i…
 
Many networks are designed and operationally drive by the configuration and management of features supporting applications and use cases. For network engineering to catch up to the rest of the operational world, it needs to move rapidly towards data driven management based on a solid understanding of the underlying protocols and systems. Brooks Wes…
 
Communication is one of those soft skills so often cited as a key to success—but what does effective communication entail? Mike Bushong joins Eyvonne Sharp and Russ White on the Hedge to discuss radical candor, and the importance of giving and taking honest feedback to relationships and business. https://media.blubrry.com/hedge/content.blubrry.com/…
 
When the interests of the end user, the operator, and the vendor come into conflict, who should protocol developers favor? According to RFC8890, the needs and desires of the end user should be the correct answer. According to the RFC: As the Internet increasingly mediates essential functions in societies, it has unavoidably become profoundly politi…
 
Decision making, especially in large organizations, fails in many interesting ways. Understanding these failure modes can help us cope with seemingly difficult situations, and learn how to make decisions better. On this episode of the Hedge, Federico Lucifredi, Ethan Banks, and Russ White discuss Federico’s thoughts on developing a taxonomy of inde…
 
The international pandemic has sent companies scrambling to support lots of new remote workers, which has meant changes in processes, application development, application deployment, connectivity, and even support. Mike Parks joins Eyvonne Sharp and Russ White to discuss these changes on this episode of the Hedge. https://media.blubrry.com/hedge/co…
 
Crossing from the domain of test pilots to the domain of network engineering might seem like a large leap indeed—but user interfaces and their tradeoffs are common across physical and virtual spaces. Brian Keys, Eyvonne Sharp, Tom Ammon, and Russ White as we start with user interfaces and move into a wider discussion around attitudes and beliefs in…
 
Combining, or stitching together, open source projects to build something unique for your network is becoming more common. What does this look like in the real world? What are some of the positive and negative aspects of building things this way? How do open source projects interact with the commercial world? Daniel Teycheney joins Tom Ammon, Jett …
 
The open source world is not much different than the commercial world in terms of building marketectures rather than useable software—largely because open source projects still rely on sources of funding and material support to build and maintain a product. Many times, however, the focus on these marketectures get in the way of real work. Join Tom …
 
When we think of automation—and more broadly tooling—we tend to think of automating the configuration, monitoring, and (possibly) the monitoring of a network. On the other hand, a friend once observed that when interviewing coders, the first thing he asked was about the tools they had developed and used for making themselves more efficient. This “s…
 
FR Routing is a widely used and supported open source routing stack. In this episode of the Hedge, Alistair Woodman, Quentin Young, Donald Sharp, Tom Ammon, and Russ White discuss recent updates, additions to the CI/CD system, the release process, and operating system support. If you’re looking for a good open source, containerized routing stack fo…
 
Everyone who’s heard me talk about container networking knows I think it’s a bit of a disaster. This is what you get, though, when someone says “that’s really complex, I can discard the years of experience others have in designing this sort of thing and build something a lot simpler…” The result is usually something that’s more complex. Alex Pollit…
 
The modern DNS landscape is becoming complex even for the end user. With the advent of so many public resolvers, DNS over TLS (DoT) and DNS over HTTPS (DoH), choosing a DNS resolver has become an important task. The ADD working group will, according to their page— …focus on discovery and selection of DNS resolvers by DNS clients in a variety of net…
 
Innovation and disruption are part the air we breath in the information technology world. But what is innovation, and how do we become innovators? When you see someone who has invented a lot of things, either shown in patents or standards or software, you might wonder how you can become an innovator, too. In this episode of the Hedge, Tom Ammon, Ey…
 
Tyler McDaniel joins Eyvonne, Tom, and Russ to discuss a study on BGP peerlocking, which is designed to prevent route leaks in the global Internet. From the study abstract: BGP route leaks frequently precipitate serious disruptions to interdomain routing. These incidents have plagued the Internet for decades while deployment and usability issues cr…
 
Everyone in networking—and beyond networking, in fact—thinks about what the future of work might look like. Jacquelyn Adams joins Eyvonne Sharp, Tom Ammon, and Russ White on this episode of the Hedge to discuss what work might look like based on this era of rapid change, and how you can prepare for that future. https://media.blubrry.com/hedge/conte…
