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.
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.
There is a rising tide of security breaches. There is an even faster rising tide of hysteria over the ostensible reason for these breaches, namely the deficient state of our information infrastructure. Yet the world is doing remarkably well overall, and has not suffered any of the oft-threatened giant digital catastrophes. ndrew Odlyzko joins Tom Ammon and I to talk about cyber insecurity.
I failed to include the right categories the first time, so this didn’t make it into the podcast catcher feeds correctly…
Network engineering and operations are both “mental work” that can largely be done remotely—but working remote is not only great in many ways, it is also often fraught with problems. In this episode of the Hedge, Roland Dobbins joins Tom and Russ to discuss the ins and outs of working remote, including some strategies we have found effective at removing many of the negative aspects.
Fastnetmon began life as an open source DDoS detection tool, but has grown in scope over time. By connecting Fastnetmon to open source BGP implementations, operators can take action when a denial of service event is detected, triggering black holes and changing route preferences. Pavel Odintsov joins us to talk about this interesting and useful open source project.

Nash King (@gammacapricorni) joins Russ White and Tom Ammon in a wide ranging discussion of ethics in IT, including being comfortable with standing up and saying “no” when asked to do something you consider unethical and the virtue ethic. This is meant to be the first of a series of episodes on this topic.
Almost every company relies on open source software in some way, which leads to the natural question—how will the heart of the network, routing and switching, be impacted by open source software? In this episode of the Hedge, Sue Hares, Donald Sharp, and Russ White discuss the current and future world of open source routing software. Donald is one of the main drivers of the FR Routing open source routing stack; Russ White is a maintainer on the project and is still deeply involved in commercial routing software, and Sue Hares was deeply involved in the origins of the GateD open source routing stack.
