Heavy Networking is an unabashedly nerdy dive into all things networking. Described by one listener as "verbal white papers," the weekly episodes feature network engineers, industry experts, and vendors sharing useful information to keep your professional knowledge sharp and your career growing. Hosts Greg Ferro, Ethan Banks and Drew Conry-Murray cut through the marketing spin to explore what works—and what doesn't—in networking today, while keeping an eye on what's ahead for the industry. On air since 2010, Heavy Networking is the flagship show of the Packet Pushers podcast network.

HN729: Open Source to Closed
With “The Cathedral and the Bazaar” as his guide, Srivats launched Ostinato, his open source project, in 2010. He needed an affordable network traffic generator at his day job, he was passionate enough to build one during his nights and weekends, and end users loved it– it has been downloaded hundreds of thousands of times....

HN728: How Drivenets Leverages Ethernet Fabrics For AI Networking (Sponsored)
To run AI workloads, a network needs thousands of GPUs and those GPUs must operate in sync. If there is congestion or dropped frames, very expensive efforts could be delayed or disrupted. While there are advantages to using Ethernet for AI networking (including engineers well-trained in the protocol and a robust ecosystem), it wasn’t designed... Read more »

HN724: How Packets Move Through a Network Device
Today we metaphorically pop open the hood of switches and routers, taking a look at the mechanics of how they work. We cover the three states: configuration, operational, and forwarding. We talk RIB and FIB, along with CAM, TCAM, and MPLS. We also cover line rate, port-to-port latency, and buffers. Whether it’s been awhile since... Read more »
Customer Reviews
Deep dive into both current
Heavy Networking is a deep dive into up and coming and relevant technologies in our business. And they get on experts that show you the practical applications of the technologies and how you're going to use it, what situations you're going to use it in, so that you're aware of what's out there. What I think is important is that they're both currently widely deployed technologies and the stuff that's still on the startup scene that you probably don't want to deploy yet. But in three years it's going to be what's deployed
Great podcast
Wonderful information!
Such a wealth of knowledge! 🧠
This is one of the most insightful podcasts that I have ever come across! The Packet Pushers team does such a great job of sharing their wisdom and I love how they lead meaningful conversations with guests who bring so much experience to the table. If you’ve got a question related to anything “networking technology” this is definitely the place to go. Highly recommend checking this show out - you won’t be disappointed!
