The Hedge 63: Anycast with Andree Toonk
Anycast is a bit of a mystery to a lot of network engineers. What is it, and what is it used for? Andree Toonk joins Tom and Russ on this episode of the Hedge to discuss the many uses of anycast, particularly in the realm of the Domain Name Service (DNS). Andree helped build the OpenDNS network and service, so he has deep experience with anycast routing on the DFZ.
The Hedge 62: Jacob Hess and the Importance of History
At first glance, it would seem like the history of a technology would have little to do with teaching that technology. Jacob Hess of NexGenT joins us in this episode of the Hedge to help us understand why he always includes the history of a technology when teaching it—a conversation that broadened out into why learning history is important for all network engineers.
The Hedge 61: Pascal Thubert and the RAW Working Group
RAW is a new working group recently chartered by the IETF to work on:
The Hedge 60: Ben Andresen and Growing Teams
How can managers grow teams that add value to the company? Teams are made up of people, and people need to grow, so the key is in learning how to grow people. Join us at the Hedge as we discuss learning paths, doing what’s right for the company and the person, and growing teams by growing people.
The Hedge 59: Dan Blum and Rational Cybersecurity
Security has taken on an aura of mystery to many network engineers—why can’t we approach security in the way we do many other topics, rationally? It turns out we can. Dan Blum joins Tom Ammon and Russ White to discuss the concepts and techniques behind rational cybersecurity.
The Hedge 58: Michael Kehoe and eBPF
Most packet processing in Linux “wants” to be in the kernel. The problem is that adding code to the kernel is a painstaking process because a single line of bad code can cause havoc for millions of Linux hosts. How, then, can new functionality be pushed into the kernel, particularly for packet processing, with reduced risk? Enter eBPF, which allows functions to be inserted into the kernel through a sort of “lightweight container.”
Michael Kehoe joins Tom Ammon and Russ White to discuss eBPF technology and its importance.
The Hedge 57: Brian Trammell and PANRG
Brian Trammell joins Alvaro Retana and Russ White to discuss the Path Aware Research Group in the IRTF. According to the charter page, PANRG “aims to support research in bringing path awareness to transport and application layer protocols, and to bring research in this space to the attention of the Internet engineering and protocol design community.”
