IBM Buys HashiCorp; Running Data Centers With Vegetable Oil?

We welcome guest commentator Kyler Middleton of Day Two Cloud to discuss the IBM/HashiCorp deal, then pivot to new Wi-Fi 7 APs from HPE Aruba Networking, and discuss why a data center builder in Ireland is constructing a power generation plant alongside the generator–and powering it partly with vegetable oil. Plus much, much more. | LISTEN NOW

Using ZTNA for VPN Consolidation, Protecting Dev Access with SSE

Zero Trust Network Access, or ZTNA, is a core element of a Security Service Edge because it enables secure remote access to on-prem and cloud-based applications. On today’s episode, sponsored by HPE Aruba Networking, we dig into ZTNA from HPE’s perspective and hear customer stories on how it’s being used for third-party access, VPN consolidation, and protecting developer access to testing and QA resources. Our guests from HPE Aruba Networking are John Spiegel, Director, Network Transformation (Field CTO); and Jaye Tillson, Director of Strategy (Field CTO). | LISTEN NOW

Wireless Training and Certifications for IoT

With the rapid growth of IoT across enterprise and industrial spaces, now is a good time to check in on the wireless training and certification landscape beyond Wi-Fi. Today, Tom Carpenter, the Director of Education for the Certified Wireless Network Professionals joins us to give a lay of the land. He explains how the protocols in their programs have been selected (Zigbee, Thread, 6LoWPAN, ISA 100.11a, wirelessHART, etc.), and which ones they are eying for the future (here’s looking at you, HaLow). He describes the different certifications and what they look like for folks already experienced in Wi-Fi. Plus, if you stayed tuned til the end, you’ll hear his “emotional” answer to “If you were starting your career in wireless right now, would you start in IoT or Wi-Fi?” | LISTEN NOW

Planning for a Post Quantum Cryptography World

The classical encryption algorithms that currently undergird our IT infrastructure will be broken once there’s a powerful and stable enough quantum computer to do the job. Quantum-resistant algorithms are being developed by NIST, but implementation and deployment of these algorithms still have to be addressed. So what does all this mean for busy IT and security teams? Avesta Hojjati is our guest today. He explains how quantum computers attack classical algorithms, how quantum-resistant algorithms work, and how to understand the risks presented by the emergence of a post-quantum cryptography world. We also discuss how quantum-resistant algorithms might be deployed, how organizations can assess and manage this process, and good questions to ask your vendors. Of course, we also cover the biggest headlines in cybersecurity: Palo Alto Networks, Cisco, and PuTTY vulnerabilities. | LISTEN NOW

The Team Behind Nautobot (Part 1)

Today we chat with the maintainers of Nautobot, the open source network source of truth and network automation platform. Jason Edelman, Ken Celenza, John Anderson explain how their day jobs at professional services company Network to Code informs their work on Nautobot. They walk us through Nautobot’s core, out-of-the-box capabilities as well as the extensibility features beyond that. Then they give us a little teaser about their new book, Network Automation with Nautobot, which we’ll cover in-depth in the next episode. | LISTEN NOW

IPv6 Basics: ICMPv6

As part of our ongoing series on IPv6 basics, today we cover the differences you should be aware of between ICMPv4 and ICMPv6. Internet Control Message Protocol (ICMP) is the protocol that lets you test reachability: pings, echoes, TCP connections, etc. We explain what you need to know and why you need to know it, particularly around filtering your internet edge and setting maximum packet size. And of course we give the age old advice about learning in networking: Play with your Wireshark. | LISTEN NOW

Juniper’s PTX Platforms: 800GE and Double-Density 400GE for DC and WAN

The future has arrived: 800GB Ethernet is here. Amit Bhardwaj and Dmitry Shokarev from today’s sponsor, Juniper Networks, join the show to tell us all about Juniper’s 800GB Ethernet and what we need to know as engineers: use cases, transition plans, fiber and power needs (a lot less than you’d think). We also go over the Juniper PTX router family that supports 800GE: line card specs, optics, the capacity for 2000km router-to-router lengths, etc. Finally, we dig into the Express 5 silicon that makes it all go. We talk about Juniper’s chip design philosophy, its use of chiplets, and its built-in features including line-rate MACsec, scalable SRv6, hierarchical QoS, Inline IPFIX, and more. Listen through until the end to hear Ethan ask the question he just can’t hold in: Does this mean 1T Ethernet is on the way? | LISTEN NOW
