Pi to Go: Introducing the WLAN Pi Go

The new WLAN Pi Go is small, lightweight Wi-Fi testing tool. It can sniff Wi-Fi frames, measure signals, decode packets, and more. The tool snaps to the back of your phone and connects via a short cable for data and power. The small form factor makes it ready to take it along and test any Wi-Fi network. Keith Parsons talks with the WLAN Pi Go creators about the device, what it can do for you, and how it works with other WLAN Pis and third-party tools. | LISTEN NOW

IPsec Basics

It's time to talk crypto. No, not the Bitcoin kind. Ethan and Holly introduce the basics of IPsec, the protocol that authenticates and encrypts traffic between endpoints. They discuss what it is, how it provides trustworthiness and secrecy to IP traffic, and common use cases. They review the different types of IPsec protocols and modes, and then describe how IPsec is implemented in the real world. | LISTEN NOW

IPv6 Transition Technology Options

Transitioning from IPv4 to IPv6, or at least IPv6-mostly, is no easy task. Today's show provides some education and advice about IPv6 transition mechanisms. We cover options such as NAT64, DNS64, PREF64, and more, as well as use cases. Also, if your technology vendors aren't offering some of these mechanisms, ask for them - you're probably not the only one who has an IPv6 transition project.| LISTEN NOW

From ARPANET to the Stars: Vint Cerf on the Past and Future of the Internet

Vint Cerf, widely recognized as one of the fathers of the Internet, is today's special guest on Total Network Operations. He currently serves as Vice President and Chief Internet Evangelist at Google. His pioneering work began back in the 1960's when he was involved in the ARPANET project.  Alongside Bob Kahn, Vint co-invented the TCP/IP protocols, which form the backbone of the global internet. We explore Vint's remarkable career and his insights into the evolution of networking technology. He gives his viewpoints on resistance to adopting new technologies like IPv6 and AI, the future of the internet, and the ambitious efforts to build an interplanetary internet. | LISTEN NOW

How the Bundle Protocol Enables Interplanetary Networking

How might we get network traffic from Earth to a lunar base? Or Mars? Or to spaceships carrying astronauts beyond Earth's orbit? And how do we get it back? The problem, among other things, is latency. The answer isn’t TCP/IP. The answer is the Bundle protocol. On today's Heavy Networking we talk with guest Scott Johnson bout why TCP/IP doesn't work for outer space, how the Bundle protocol deals with latency, interoperability between Earth and space-based networks, and the many challenges of operating networks in the hostile environment of outer space. | LISTEN NOW
