Just got 10 Meg Half Duplex'd
The ultimate office network punishment
This episode we build a RAG system for Cisco Docs 🤖; learn about RoCE networks at scale 💥; get subnet peering working on ExpressRoute 💪; consider what we’d do different doing NSX today 🤨; are happy not SSHing into our boxes 🤪; use Diataxis to write network docs faster 📝 and use lasers to go faster than Starlink 🔴. Let’s dive in; ⬇️

I Built a RAG System That Actually Understands Cisco Docs. Here’s What I Learned especially when it comes to knowing stuff like FHRP, VRRP and HSRP are all pretty much the same thing (don’t write to us, we’ll pre-empt it to the bin…) and understanding the many a.k.a’s of the Networking world 📕
RoCE networks for distributed AI training at scale expands on real-world deployments of AI Fabrics in Meta with useful details about the speeds, feeds and some characteristics of their setup 🚀
Building the Future of Network Automation: RALPH, GAIT, and pyATS in Harmony uses Ralph’s looping construct to great affect, with git for version control and “go back in time” capability, it’s an unbeatable way of adding AI magic to your NetOps 🤖
A Traffic Engineering Process Perspective looks at the process mechanics and levers behind TE and how to think about which types of traffic might, and might not, be good candidates to TE tunnel vs those that are better left alone 💡
Rethinking Infrastructure Operations in the Age of AI has some ideas about AIOps in NetOps you might want to consider 🦾
Subnet peering and ExpressRoute works a little differently than you might expect or be able to AI your way out of, dig in and learn more if you’re deep in the Azure network space ☁️
Things I Would Do Differently If I Designed an NSX Platform Today didn’t include our hot take of “don’t”, but that’s probably for the best ⛈️
From InfiniBand to Ultra Ethernet Why AI Networks Had to Rethink RDMA on Ethernet…. because Ethernet. Always. Wins. Always 🛜
