Sam shares his unconventional journey from working at a gas station to becoming a Wi-Fi networking professional. He emphasizes the value of certifications and seizing opportunities. Tauni, with a background in psychology and marketing, discusses her transition into wireless technology. She highlights the importance of understanding technical details to design effective networks. We also talk about continuous learning, certifications, and mentorship as keys to success. | LISTEN NOW |
EP 052 | MARCH 4, 2024The State of the Network Security Market In 2025How big is the network security market? Is it growing? How is that growth measured? What effect is SASE having on security hardware revenues? Will security products or security operators get more effective thanks to AI? We put these and other questions to Mauricio Sanchez. He's the Sr. Director, Enterprise Security and Networking, at the Dell'Oro Group, a quantitative analyst firm that covers security, networking, and other IT industries. We also get a peek behind the scenes of how analysts do their jobs, and who they do it for. | LISTEN NOW |
EP 266 | MARCH 5, 2024How AI Affects the Developer ExperienceLet's talk about how AI affects the developer experience, particularly for open source tools such as Terraform. We're joined by guests Welly Siauw and Tyler Lynch to examine a project that leverages AI to automate the generation of documentation and examples for AWS Terraform providers. We delve into the iterative development process with AI, the importance of human oversight to ensure quality and accuracy, the cost benefits, and the potential of open-source for broader community use. | LISTEN NOW |
EP 016 | MARCH 6, 2024Routers Are Not Switches...Are They?The line between switches and routers can get a little blurry. On today's N Is For Networking, we try to clear things up. We start by defining what a router and switch are, and then provide some historical and technical context to better understand the differences. Then we discuss how modern switches have evolved to incorporate routing capabilities, along with ASICS, device features, and licensing. Bonus material: talking through a few network designs that incorporate switches and routers. | LISTEN NOW |
EP 170 | MARCH 6, 2024RFC 7050 vs RFC 8781 for IPv6 Prefix DiscoveryIWe dive into two RFCs for discovering IPv6 prefixes: 7050 and 8781. Why these two? First, 8781 is being proposed as preferential to 7050. Second, co-host Nick Buraglio is an author on 8781 and has insights to share. We start with some background on RFC 7050, including the limitations that led to the development of RFC 8781. We also look at the challenges of managing network configurations in large enterprises and the advantages of centralizing configurations on routers. We conclude with a call for network operators to review and comment on RFC 8781. | LISTEN NOW |
EP 019 | MARCH 7, 2024A Look At NetOps Inside a Colocation FacilityEver wonder what network operations are like inside a colo facility? Today we talk with Scott Brookshire, CTO of OpenColo. Scott shares his journey into networking, how OpenColo was founded, and the evolution of the company from a few servers to a significant data center operation. We delve into what it means to run a colo, including automation for data center management, redundancy, power management, and supporting BGP. Plus, Scott discusses the importance of transparency in customer service. | LISTEN NOW |
EP 771 | MARCH 7, 2024Is The CCIE Still Worth It In 2025?The CCIE remains the gold standard for networking certifications. But these days there are lots of other avenues for developing your skills and advancing your networking career, including network automation, cloud networking, and yes, even AI. So is the CCIE still worth it? We chew on this topic with Eman Conde, best known as the CCIE agent. He’s had his finger on the pulse of the CCIE market for as long as I can remember. We talk about the market for CCIEs in 2025 and whether it's still your ticket to the networking big leagues. | LISTEN NOW |

Routing Forwarding Engines: Part 4 - Discarding, Punting, and DPDK
For the penultimate post in this series on getting from the routing to the forwarding table, let's look at the diagram below and ask a question.
What happens if the device ingests a packet that the Forwarding Engine (FE) cannot process for some reason? Perhaps the packet requires deep packet inspection or contains an IP header like the IPv6 hop-by-hop header. There are two options: discarding and punting. | READ NOW

Landing Your First Network Engineering Role
John, a CCNA based in the United States, writes in about trying to land his first networking role. I'm an aspiring network engineer who's been facing a bit of a challenge landing my first role after countless applications, volunteer inquiries, etc. Just haven't been able to successfully land anything at the moment, however I do keep myself informed with the latest trends in the space, persistently learn new things, studying for more certs as well as keeping myself busy with lab practice via Packet Tracer. Being that you have decades worth of experience racked up under your belt what advice would you give me at such an early stage in my career to potentially land a spot? Follow the link for Ethan’s insights. | READ NOW
