Hedge 156: Functional Separation in Network Design with Kevin Myers

Modularization is a crucial part of network design because it supports interchangeability, reduces the size of failure domains, and controls security domains. One critical aspect of modularization is functional separation, which argues for separating services onto specific physical and logical resources. Kevin Myers joins Tom Ammon and Russ White on this episode of the Hedge to discuss the theory and importance of functional separation in network design.

The Hedge 155: DNS Deployment in Real Life with Andreas Taudte

Network engineers normally use and support DNS as a service, but don’t tend to deploy, manage, and interact with DNS servers at an application level. For this episode of the Hedge, Andreas Taudte joins Tom Ammon and Russ White to discuss the many lessons learned from planning and deploying DNS as a service.

Hedge 154: Path Aware Networking Research Group

Applications generally assume the network provides near-real-time packet transmission without regard for what the application is trying to do, what kind of traffic is being transmitted, etc. Back in the real world, its often important for the network to coordinate with applications to more efficiently carry traffic offered. The Path Aware Research Group (PANRG) in the Internet Research Task Force (IRTF) is looking at the problems involved in understanding and signaling the path characteristics to applications.

In this episode of the Hedge, Brian Trammel joins Tom Ammon and Russ White to discuss the current work on path aware networking.

Hedge November Update

November update on upcoming shows and training. My upcoming training on Safari Books Online is here.

Hedge 153: Security Perceptions and Multicloud Roundtable

Tom, Eyvonne, and Russ hang out at the hedge on this episode. The topics of discussion include our perception of security—does the way IT professionals treat security and privacy helpful for those who aren’t involved in the IT world? Do we discourage users from taking security seriously by making it so complex and hard to use? Our second topic is whether multicloud is being oversold for the average network operator.

Hedge 151: Cecilia Testart and the Value of the RPKI

If you advertise routes through a provider to the global Internet, you might be wondering if you should go through the trouble of registering in the RPKI and advertising ROAs. What is the tradeoff for the work involved in what seems like a complex process? Cecelia Testart joins Jeremy White and Russ White to discuss recent work in measuring the value of the RPKI.

Hedge: October Update

What’s going on with the Hedge? What am I teaching this coming month? Listen to this short update to find out all the news.

Hedge 149: Roundtable

Who’s using the cloud? Is cheap complexity harmful? Are mainframes dead? Is this the end of specialized networking hardware? Is it a good idea to have server folks build networks? On this episode of the Hedge, Tom, Eyvonne, and Russ go “guestless” in a roundtable about various topics and ideas in the networking world.

Hedge 148: The SRE with Niall Murphy (part 2)

It seems like only yesterday we started talking about the Site Reliability Engineer, and their place in the IT ecosystem. Over the last several years, the role of the SRE has changed—and it’s bound to continue changing. On this episode of the Hedge, Niall Murphy joins Tom Ammon and Russ White to discuss the changing role of the SRE, and what the SRE could be.
