The Hedge Podcast Episode 19: Optional Security is not Optional

By Russ | 22 January 2020 |

Brian Trammell joins Alvaro Retana and Russ White to discuss his IETF draft Optional Security Is Not An Option, and why optional security is very difficult to deploy in practice. Brian blogs at http://trammell.ch and also writes at APNIC.

The History of Programmable Control Planes

By Russ | 21 January 2020 |

On this episode of the History of Networking, organized through the Association of Computing Machinery, Jennifer Rexford joins Donald Sharp and Russ White to discuss the history of programmable control planes. Dr. Rexford is the Gordon Y. S. Wu Professor in Engineering at Princeton University in New Jersey.

The Hedge Podcast Episode 18: Programming Fundamentals for Network Engineers

By Russ | 15 January 2020 |

Network engineers do not need to become full-time coders to succeed—but some coding skills are really useful. In this episode of the Hedge, David Barrosso (you can find David’s github repositories here), Phill Simmonds, and Russ White discuss which programming skills are useful for network engineers.

The Hedge Podcast Episode 17: Michael Natkin and Strong Opinions Loosely Held

By Russ | 8 January 2020 | Comments Off on The Hedge Podcast Episode 17: Michael Natkin and Strong Opinions Loosely Held

According to Michael Natkin, “in the tech industry, with our motto of “strong opinions, loosely held” (also known as “strong opinions, weakly held”), we’ve glorified overconfidence.” Michael joins Tom Ammon and Russ White to discuss the culture of overconfidence, and how it impacts the field of information technology.

The History of BSD and IP Stacks with Rodney Grimes

By Russ | 7 January 2020 | Comments Off on The History of BSD and IP Stacks with Rodney Grimes

BSD is one of the first UNIX implementations, and the IP stack in BSD is one of the first widely used open-source implementations of TCP/IP. Rodney Grimes joins us at the History of Networking to talk about the origins of BSD and these first IP implementations.

The Hedge Podcast 16: Pavel Odinstov on Fastnetmon Use Cases

By Russ | 18 December 2019 | Comments Off on The Hedge Podcast 16: Pavel Odinstov on Fastnetmon Use Cases

In a previous episode, Pavel joined the Hedge to talk about the origins and architecture of the Fastnetmon open source network monitoring tool. In this episode, Pavel joins Russ White and Tom Ammon to talk about the many creative use cases to which you can apply this tool.

The History of Interop with Dan Lynch

By Russ | 10 December 2019 | Comments Off on The History of Interop with Dan Lynch

Interop is the longest running “show” in the networking space—but it didn’t not start as a “show” at all. Dan Lynch, the founder of Interop, joins us at the History of Networking to talk about how Interop really started (hint, it’s in the name). One important lesson to learn through this discussion: it is not enough to have standards or open source; in the realm of network protocols, being able to prove multiple vendors can work together is important, too.

The Hedge Episode 14: Ron Bonica and SRM6

By Russ | 3 December 2019 | Comments Off on The Hedge Episode 14: Ron Bonica and SRM6

Srv6 uses IPv6 header fields to perform many of the same traffic engineering, fast reroute, and other functions available through MPLS. The size of the header with a large label stack, however, can be problematic from a performance perspective. Further, adding the concept of actions to SRv6 would bring a lot of new functionality into view. On this episode of the Hedge podcast, Ron Bonica joins Russ White to talk about SRM6, or Segment Routing Mapped to the v6 address space, which compacts the label stack and actions into a smaller space, resulting in an easier to deploy version of SRv6.

The History of Multipath TCP with Olivier Bonaventure

By Russ | 26 November 2019 | Comments Off on The History of Multipath TCP with Olivier Bonaventure

MultiPath TCP (MPTCP) is an effort towards enabling the simultaneous use of several IP-addresses/interfaces by a modification of TCP that presents a regular TCP interface to applications, while in fact spreading data across several subflows. Benefits of this include better resource utilization, better throughput and smoother reaction to failures.

The Hedge Podcast 13: Ivan Pepelnjak

By Russ | 19 November 2019 | Comments Off on The Hedge Podcast 13: Ivan Pepelnjak

In this episode of the Hedge, Tom Ammon and Russ White are joined by Ivan Pepelnjak of ipSpace.net to talk about being old, knowing about how things are going to break before they do, and being negative. Along the way, we discuss the IETF, open source, and many other aspects of the world of network engineering.
