HN795 - Adventures In Latency

After creating an alternative to smokeping in GoLang, I spoke with Ethan over at the packet pushers and we thought “why not do a podcast about latency?” Latency is an important, often overlooked, and less understood aspect of networking. This rings true regardless of the network type - HPC, wide area, carrier, data center, and campus all need to have reasonable latency in order to perform their intended functions. So, circling back to what I thought was my very first Packet Pushers guest spot, but was actually my second, we talk about my favorite toolkit, PerfSonar, and many more.

IPB182 - IPv6 Transition Technology Options

Transition technologies surrounding IPv6 can be a tad bit overwhelming in their subtle nuance. Keeping up with the differences is no easy task. Today’s show provides some education and advice about IPv6 transition mechanisms. We cover options such as NAT64, DNS64, PREF64, and more, as well as use cases. Also, if your technology vendors aren’t offering some of these mechanisms, ask for them – you’re probably not the only one who has an IPv6 transition project.

IPv6 Statistics

Over the years one of the most common responses received when asking “does your $widget support IPv6?” is “well, no one has asked for it”, or “no one actually uses IPv6”. To myself and others that have been actually using IPv6 for well over 20 years, this is a tired, uninformed, and overall dull response to a legitimate feature question. Over the last 4 years, and likely due to the explosion of IPv6 deployments, this has become significantly less common of a reply.
