HN817: Is There a Better Way to Do Software Defined Networking?
Software Defined Networking (SDN) is a centralized architecture in which a controller, or a hierarchy of controllers, runs software that computes network-engineered paths and pushes that forwarding scheme into the network. It’s also very co
HN816: Inside the Case: A Hardware Deep Dive with Meter (Sponsored)
Our topic today is the designing and building of high-performance networking hardware. If you assume the hardware details don’t matter, you’re missing the intentional engineering required to build truly reliable and quiet infrastructure. In
HN815: All About PCE
Traditional routing protocols like OSPF simply choose the “shortest” path. If the shortest path is full of traffic and there are alternate paths carrying nothing, OSPF can’t help you. Path Computation Element (PCE) along with Path Computati
HN814: Automating Your Network with Cisco Crosswork Workflow Manager (Sponsored)
Our topic today is building and running network workflows. If your network workflows live in a spreadsheet, a SharePoint document, or in your head, you really need a workflow manager. A workflow manager brings scalability, repeatability, an
HN813: What Should Networkers Know About Software Development (and Vice Versa)?
What should network engineers know about software development? What should software developers know about networking? Ethan and Drew sit down with Chris Rapier and Nick Buraglio to discuss why crossing these silos can improve outcomes for e
HN812: Nokia EDA: AI Ops You Can Trust (Sponsored)

HN809: EVPN All the Things!
It’s been over a decade since the first Packet Pushers podcast on EVPN. Now, guest Jeff McAdams can legitimately suggest that we “EVPN all the things.” Hosts Ethan Banks and Drew Conry-Murray dig into Jeff’s stance on EVPN/VXLAN. They look
HN808: Is IT a Young Person’s Game?
Is the ideal IT employee just leaving college or a veteran with years of experience? Russ White joins Ethan Banks and Drew Conry-Murray to discuss the complexities of this question. Younger professionals just out of college are more willing
HN807: A ‘CLI Lifer’ No More
Andy Lapteff once considered himself a ‘CLI lifer.’ As a network engineer he wasn’t interested in Python. He didn’t want to learn to code. He had no desire to embrace any of the developer-like processes and tools creeping into the professio
HN806: Let’s Get NUTS!
Unit testing is a software development practice for checking that an individual component of code works before integrating that unit with other components in a larger program. A new open source project called Network Unit Testing System, or
HN805: The Past, Present, and Future of NANOG
NANOG, or the North American Network Operation Group, is an organization committed to the continuing advancement of an open, secure, and robust Internet. At the NANOG Conference 95 in late October 2025, Ethan Banks chatted with Steve Feldma
HN804: How Prisma SASE Builds on Public Clouds for Scale, Resiliency (Sponsored)

HN803: How to Start a Networking Meetup
On today’s episode, we take a break from one’s and zero’s for a discussion about starting a networking meetup. Our guest is Steinn “Steinzi” Örvar, who recently founded the ISNOG, a network operators’ group in Iceland. We quiz Steinzi about
HN802: Unifying Networking and Security with Fortinet SASE: Architecture, Reality, and Lessons Learned (Sponsored)
The architecture and tech stack of a Secure Access Service Edge (SASE) solution will influence how the service performs, the robustness of its security controls, and the complexity of its operations. Sponsor Fortinet joins Heavy Networking
HN801: Will a Natural Language Interface (NLI) Replace Your CLI?
Could an LLM or some kind of an AI-driven language model, such as a natural language interface, someday replace our beloved CLI? That is, instead of needing to understand the syntax of a specific vendor’s CLI, could a language model allow n
HN800: Root Cause Analysis for the Entire Stack (Sponsored)
Today’s show is one of those “We’re living in the future” episodes, where we talk about using AI to perform root cause analysis of a performance issue. But not root cause analysis for just the networking part of the stack. The full stack. W
HN799: Multi-Homing IPv6 to Your Home Lab
If you’ve got an Autonomous System Number (ASN) and an IPv6 block, you too can multi-home IPv6 to your home lab! Sounds easy, right? Well, maybe…but today we’re going to discuss why you’d want to and how you can do that with guest Anton Lön
HN798: Fortinet Offers a SOC Every Org Can Grow Into (Sponsored)
On today’s Heavy Networking: the Security Operations Center, or SOC. When I think of a SOC, I picture a miniature version of NASA’s mission control: lots of computers, lots of people, some big boards with lines and arrows and telemetry scro
HN797: What To Do When The Business Asks for “AI”
When someone from the executive suite starts an AI initiative, what does that mean to you, the network engineer? The executive suite probably doesn’t know what their AI idea might mean for infrastructure. They might only have a vague idea o
HN796: The Why and How of Making Your Infrastructure Quantum-Safe (Sponsored)
Your production IT operations are almost certainly using cryptography libraries that are not quantum-safe, and the time to begin planning a cryptography overhaul is now. But this is likely to be a daunting project because it touches everyth
