Cisco Unveils Quantum Networking Prototype; Arista Earns Record Revenues

Take a Network Break! We start with follow-up from a listener on the best way to listen to our podcast that helps the most. We discuss two critical security issues. On the news front, Juniper Networks' AI-powered Marvis Minis can now measure WAN performance to simulate a user's experience, and Juniper has released a Marvis client agent to measure Wi-Fi performance from the device to the AP.Cisco has unvieled a prototype quantum networking chip, Cadence launches an Nvidia-based supercomputer, and Gluware adds SONiC support and native NetBox integration to its network automation platform.IBM has launched a new generation of its LinuxONE mainframe built around IBM processors and accelerators, and European telcos want exclusive access to 6 Ghz spectrum for mobile use. | LISTEN NOW

How Capable Is My Wi-Fi Client?

Today on Heavy Wireless we welcome Francois Verges, who designed a database tool to help Wi-Fi engineers easily find client device capabilities. It provides quick access to key specs like data rates, Wi-Fi versions, and vendor documentation. It's designed to be a go-to option when looking for Wi-Fi client specifications. We discuss why he developed the database, where it gets its information from, and how it draws from work done by Michael Habano. We also talk about how you can use it and contribute to it to help keep it up to date. This episode was inspired by Francois's talk "How Capable Is My Wi-Fi Client," which he presented at WLPC Phoenix 2025.. | LISTEN NOW

Hunting for Host Security and Performance Issues with Stratoshark

Stratoshark is a new tool from the Wireshark Foundation that analyzes system calls on a host. Network, security, and application teams can use Stratoshark to diagnose performance issues and investigate behavior that may indicate malware or other compromises of the host. Packet Protector talks with Gerald Combs of the Wireshark Foundation about why you'd want to analyze system calls, how those calls are captured and analyzed, what operating systems Stratoshark works with, how the UI mirrors Wireshark to provide a familiar environment for users, and more. | LISTEN NOW

The Physics of DevOps

How do you measure developer performance and productivity? On today's Day Two DevOps, we look at different methods with guest Laura Tacho, the CTO at DX. We explore industry benchmarks such as the DORA report, SPACE, and DevEx. Laura also introduces us to Core 4, a project she's been working on that provides a new framework for measuring developer productivity and to support decision making within an organization. We also talk about how AI is shifting cognitive load to senior developers. | LISTEN NOW

What Is a Tunnel?

Let's dig into tunnels. While some network engineers may want to quibble, a tunnel is when you put one packet inside of another packet to carry it across a network (frames also come into the picture, so hold off on your follow-ups for now). On today's N Is For Networking, Ethan and Holly explore this working definition of a tunnel, talk about security and traffic engineering use cases for tunnels, and touch on different tunneling protocols. This week's bonus material is a discussion about how overlays and underlays relate to tunnels. | LISTEN NOW

IPv6 Basics - Link Local Addresses

Our IPv6 Basics series continues with Link-Local addresses. Link-local addresses are unicast addresses used for addressing on a single link. The intent of link-local addresses is to let devices that may not have a router or global unicast address allocation mechanism still be able to communicate on a network segment. On today's show we dig into how link-local addresses work, what to do with them, potential issues with link-local addresses, and more. | LISTEN NOW

CCIE Service Provider Free Workbook & Track Update

While studying for the CCIE Service Provider certification, Andrew Ohanian assembled a workbook to help him prepare. It's packed with lab exercises, and Andrew has turned it into a free Web resource that anyone can access. On today's Heavy Networking, we talk with Andrew about what's in the guide, the state of the CCIE SP, the job market value of this cert, labbing suggestions, and much more. | LISTEN NOW
