    HN799: Multi-Homing IPv6 to Your Home Lab
    Oct 3 2025
    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 Lönnerbro. Anton is a solutions architect at a managed service provider... Read more »

    HN798: Fortinet Offers a SOC Every Org Can Grow Into (Sponsored)
    Sep 26 2025
    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 scrolling across the screens. I also think of SOCs as requiring a lot of gear,... Read more »

    HN797: What To Do When The Business Asks for “AI”
    Sep 19 2025
    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 of what they’re even trying to accomplish with an AI initiative. Regardless, that initiative puts... Read more »

    HN796: The Why and How of Making Your Infrastructure Quantum-Safe (Sponsored)
    Sep 12 2025
    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 everything: clients, servers, apps, network devices, middleboxes, and so on. Daunting, but doable. We talk with Richu Channakeshava, Principal... Read more »

    HN795: Adventures In Latency
    Sep 5 2025
    Monitoring and troubleshooting latency can be tricky. If it’s in the network, was it the IP stack? A NIC? A switch buffer? A middlebox somewhere on the WAN? If it’s the application, can you, the network engineer, bring receipts to the app team? And what if you need to build and operate a network that’s... Read more »

    HN794: How the Bundle Protocol Enables Interplanetary Networking
    Aug 29 2025
    How might we get network traffic from Earth to a lunar base? Or Mars? Or to spaceships carrying astronauts or probes exploring space? And how do we get it back? The problem, among other things, is latency. The answer isn’t TCP/IP. The answer is…complicated. On today’s Heavy Networking we explore the challenges of getting packets... Read more »

    HN793: A Deep Dive Into High-Performance Switch Memory
    Aug 22 2025
    Today’s episode is all about high-performance memory in switches. We dig into the differences among TCAM, SRAM, DRAM, and HBM, and all the complex tradeoffs that go into allocating memory resources to networking functions. If you’ve ever had to select a Switching Database Manager template or done similar operations on a switch, this is your... Read more »

    HN792: Understanding Agentic AI for Network Operations (Sponsored)
    Aug 15 2025
    LLMs and AI-powered chatbots are becoming a regular feature of network operations tools and vendor product portfolios. Now the next iteration of AI in network ops and automation is likely to be agentic. On today’s Heavy Networking, sponsored by HPE Juniper Networking, we talk about what agentic AI actually means, how AI agents will accomplish... Read more »
