    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

    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 »

  • HN791: Should You Build or Buy Your Automation Platform?

    HN791: Should You Build or Buy Your Automation Platform?
    Aug 8 2025
    Perhaps the biggest question around adopting network automation is whether you should build a solution using open source tools and a lot of coding glue, or buy a network automation platform from a vendor and construct your automation solution on top of that. Either way has tradeoffs. Network engineer Lee Harper joins Heavy Networking to... Read more »

    HN790: From Rule-Based to Goal-Based: Rethinking Autonomous AI Operations (Sponsored)
    Aug 1 2025
    On Heavy Networking today, AI operations for networking. That is, how do we delegate some amount of responsibility for network operations to artificial intelligence? Cisco is our sponsor, and our guests are Omar Sultan, Director for Product Management of Automation and AI; and Javier Antich, Chief Mad Scientist for AI (yes, that’s his title!). We talk...
