Hedge 94: Josh Slater and Quantum Networking

If you’re like me, you’ve heard a lot of hype about quantum—but you’ve never really been able to understand what quantum networking might be useful for. On this episode of the Hedge, Josh Slater, who works in the field of quantum networking, Ethan Banks, and Russ White discuss the current state of quantum networking and potential use cases for the technology. Things are farther along than you might think.

Hedge 93: Dinesh Dutt and Observability

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 as Dinesh, Tom, And Russ talk about observability, telemetry, and Dinesh’s open source network observability project.

Hedge 92: The IETF isn’t the Standards Police

In most areas of life, where the are standards, there is some kind of enforcing agency. For instance, there are water standards, and there is a water department that enforces these standards. There are electrical standards, and there is an entire infrastructure of organizations that make certain the fewest number of people are electrocuted as possible each year. What about Internet standards? Most people are surprised when they realize there is no such thing as a “standards police” in the Internet.

Listen in as George Michaelson, Evyonne Sharp, Tom Ammon, and Russ White discuss the reality of standards enforcement in the Internet ecosystem.

Hedge 91: Leslie Daigle and IP Addresses Acting Badly

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. Listen in as Leslie Daigle of Thinking Cat and the Techsequences podcast, Tom Ammon, and Russ White discuss just such an experiment and its results.

Hedge 90: Andrew Wertkin and a Naïve Reliance on Automation

Automation is surely one of the best things to come to the networking world—the ability to consistently apply a set of changes across a wide array of network devices has speed at which network engineers can respond to customer requests, increased the security of the network, and reduced the number of hours required to build and maintain large-scale systems. There are downsides to automation, as well—particularly when operators begin to rely on automation to solve problems that really should be solved someplace else.

In this episode of the Hedge, Andrew Wertkin from Bluecat Networks joins Tom Ammon and Russ White to discuss the naïve reliance on automation.

Hedge 89: Dana Iskoldski and A House Divided

Bluecat, in cooperation with an outside research consultant, jut finished a survey and study on the lack of communication and divisions between the cloud and networking teams in deployments to support business operations. Dana Iskoldski joins Tom Ammon and Russ White to discuss the findings of their study, and make some suggestions about how we can improve communication between the two teams.

The Hedge 88: Todd Palino and Getting Things Done

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 of the Hedge to talk about the “Getting Things Done” technique (or system) of, well … getting things done.

The Hedge 87: Jordan Holand and nPrint

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 discuss the problem and nprint, a standard packet analysis format and tools for converting from other formats.

The Hedge 86: TCPLS

TCP and QUIC are the two primary transport protocols in use on the Internet today—QUIC carries a large part of the HTTP traffic that makes the web work, while TCP carries most everything else that expects reliability. Why can’t we apply the lessons from QUIC to TCP so we can merge these two protocols, unifying Internet transport? TCPLS is just such an attempt at merging the most widely used reliable transport protocols.

The Hedge 85: Terry Slattery and the ROI of Automation

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.
