TNO067: The Impact of AI on Internet Traffic
Scott Robohn sits down with guests Lenny Giuliano and Russ White to examine whether generative AI will affect internet traffic patterns. Together they explore the role of CDNs, the importance of latency, and the potential for a shift toward edge-based inference. They also discuss the impact of data sovereignty on infrastructure and the potential return... Read more »PP119: Automating Firewall Ops To Stay Ahead of AI Threats (Sponsored)
There’s always been a gap between the discovery of a security issue and the time it takes to remediate. Now AI models can autonomously find weak points and chain together actions to exploit them. How does AI change the notion of “fast enough” for network defense? On today’s sponsored episode we dig into how FireMon... Read more »HW084: Spatial Reuse in Wi-Fi
Jake Snyder joins Keith Parsons to explain the mechanics of spatial reuse in Wi-Fi. They discuss practical implementation, the trade-offs involved in increasing signal detection thresholds, and why effective RF design remains the primary method for optimizing network performance.

Have you ever wondered how data actually travels through a Wi-Fi network? Holly and Ethan break down the fundamentals of wireless networking, including radio frequencies and channel planning. They also address the complexities of roaming, how the Wi-Fi space has changed over the years, and share advice on how to design and maintain a home... Read more »TCG080: Skills Over MCP and More
What if your MCP server shipped with its own manual? Angie Jones, VP of Developer Experience at the Agentic AI Foundation, joins William and Eyvonne to break down the Skills Over MCP working group effort, which delivers Agent Skills through MCP’s existing resources primitive (think voice over IP, not skills versus MCP). Angie shares her... Read more »NAN127: Scaling Network Automation Communities
Eric Chou welcomes Florian Lohden, a NetDevOps engineer and co-founder of the NetAuto Group, to discuss his community-building efforts and his latest adventures in network automation. Together they explore how adopting software development practices can help with network automation, and the importance of sharing knowledge within networking communities. Florian also talks about how he balances... Read more »HS138: When “One Cloud To Rule Them All” Is NOT the Answer: Repatriation for AI and more
Some enterprises are finding reasons to pull back from a cloud-first IT strategy and run workloads in on-premises data centers. John and Johna dig into why companies are making the change, including cost and AI security. They also discuss and the strategic implications for IT, and what organizations stand to gain—and lose—from repatriation. Episode Links:... Read more »
PP118: IPv6 Risks In Dual-Stack Environments (i.e. Most Environments)
Unless you’ve intentionally migrated to all-IPv6, you’re operating in a dual-stack environment. And if you haven’t accounted for v6 in your monitoring and security, you leave yourself open to risks. Today we dig into some of those risks, including VPN breakouts and how attackers can use unmanaged v6 to bypass security tools. Our guest is... Read more »TNO066: Tom Hollingsworth Before Tech Field Day
Tom Hollingsworth joins Scott Robohn to share his professional journey from a hands-on network engineer and CCIE to his current role leading events at Tech Field Day. He talks about the cyclical nature of networking hype, and advocates for specialized, subject-specific tech models over broad AI solutions. They also discuss the delicate art of facilitating...

Host Keith Parsons recently launched the WLAN Pros Toolbox, a multi-function app with all the calculators, live tools, reference materials, and Wi-Fi readings you need. Today, Keith opens the toolbox to talk about what’s in it, how it was built, and why it’s being given away for free. AdSpot Sponsor: Meter Most IT teams are... Read more »PP117: Automating Firewall Rule Changes – A Real-World Case Study
Drew talks with Joao Soares, Lead IT Security Consultant, about a project Joao undertook to automate firewall rule changes. Firewall changes can be fraught in any environment, but Joao also had to contend with working in the highly-regulated energy sector. They walk through how the project went from proof-of-concept to being widely used in production,... Read more »TCG079: Why Your State File is Actually a Distributed Systems Problem
Malcolm Matalka joins William and Eyvonne to challenge the narrative that Infrastructure as Code (IaC) is dead. Malcolm argues that the real value of IaC was never the syntax, but state and governance. Together they examine whether the state was a file problem at all, or a distributed systems problem in a JSON costume. Episode... Read more »NAN126: Fine-Tuning Open Source LLMs for Network Engineering
Eric welcomes Eduard Dulharu, a veteran network architect and the Founder and CTO of vExpertAI, to talk about how agentic AI, open-source LLMs, and digital twins are changing network operations.
