Many network engineers don’t trust AI, in part because the tech is non-deterministic and can behave in unanticipated ways. Simultaneously, the networking industry is baking AI functions deeply into operations, which has proven useful, but engineers still have their misgivings. Are these misgivings still warranted, given just how far we have advanced from chatbots and... Read more »

When engineers look to buy new technology they tend to focus on features and functionality, but there’s more to it than that. Sian Morgan joins Drew and Ethan to discuss the best practices involved in making a good technology buying decision. Sian shares how engineers can align their technical focus with broader business objectives, calculate... Read more »

If you think of BlueCat as just an IPAM or DDI company, think again. BlueCat acquired LiveAction in 2024, and since then, they’ve been working to integrate LiveAction’s network observability capabilities with the DDI portfolio. In this sponsored episode, Ryan Grande, Field CTO at BlueCat, is here to dig into how network observability and DDI... Read more »

What does it take to build your own AI agent that could help with day-to-day network tasks? Hank Preston, a Distinguished Architect at Cisco, asked himself that question. He developed a presentation that walks through all the elements one might need to build such an agent, as well as the risks to consider. On today’s... Read more »

Ethan Banks sits down with Eduard Dulharu live at AutoCon 5 to explore how agentic AI can be used to reduce Mean Time to Recovery (MTTR) for complex network environments. Eduard breaks down how these AI agents leverage deterministic workflows and custom fine-tuned models to analyze telemetry and propose solutions. Through the use of agentic... Read more »

As more applications and services rely on AI inferencing, that means more traffic on the WAN. Yes, bandwidth can solve a lot of problems, it’s not unlimited and AI inference traffic still has to share pipes with other flows. That means things like WAN latency, determinism, security, and traffic engineering are just as important as... Read more »

Shortest Path Bridging (SPB) remains an intriguing and reliable fabric technology, offering a unique approach to Ethernet that differs from more widely deployed fabrics such as EVPN/VXLAN. Jeff Wilson joins Ethan and Drew to share his experience designing and managing SPB-based fabrics. Together they discuss how SPB simplifies multicast, essential hardware design considerations for scaling,... Read more »

In this sponsored episode, HPE’s Sunalini Sankhavaram and Jose Tellado discuss the architectural evolution toward self-driving networks. Together with Ethan and Drew, they break down how integrating agentic AI enables an autonomous architecture capable of being proactive and not just reactive. They also discuss the importance of maintaining human trust in autonomous systems and how... Read more »

They also share the details of the workflows behind all your favorite shows and... Read more »

AI has complicated network automation. It has created questions: If AI generates code for me, do I need to learn Python? Should I be writing a script to gather network information if I can dispatch an AI agent to gather that information for me instead? What new skills can I skip obtaining if AI stands... Read more »

Your network is an interconnected system. A change you make on one device has consequences beyond that device. Therefore, to do your job well, you must think about the network as a whole. That’s the big idea behind a blog post written by guest Jason Gintert. He joins Ethan and Drew to talk about how... Read more »
