GPT PROMPT AND IDEAS FOR NETWORK ENGINEERS Along with some function calling with gemini

LLM is a technology which needs no introduction.

LLMs + Networking = Awesome! 😎 Just dropped a playlist with the 9 key prompting bits that’ll help you organize and understand your network stuff way better. You know what to do!

One of the most important aspect is function calling where you can use the power of structured data and calling a specific tool to help you get the information in a right format. Let me know your thoughts.

Hedge 267: Can modularization solve people problems?

Solving technology problems often involves breaking a problem into multiple smaller problems, build interaction surfaces between the pieces, and glue the pieces back into a larger system. We also know every technology problem is actually a people problem–whether in the past, the present, or the future.

Given these two points, can we say something like: “If technology and people problems are interchangeable, we should be able to solve people problems the way we solve technology problems–via modularization?”

Join us as Tom, Eyvonne, and Russ discuss how this might–or might not–apply to the real world. The second trend we’re discussing on this episode of the Hedge is the apparent movement towards government telling data center operators to “bring your own power.”

Switching, Routing, and Bridging Terminology

After discussing networking layers and addressing, it’s time to focus on moving packets across a network. Vendors love to use ill-defined terms like switching instead of forwarding, routing, or bridging, so let’s start with the terminology.

Connecting all relevant devices to a single cable would indubitably simplify any networking stack, but unfortunately, we’re almost never that lucky. We need devices in the network (typically with multiple interfaces) that perform packet forwarding between end nodes.

Worth Reading: BGP Unnumbered in 2025

Gabriel sent me a pointer to a blog post by Rudolph Bott describing the details of BGP Unnumbered implementations on Nokia, Juniper, and Bird.

Even more interestingly, Rudolph points out the elephant I completely missed: RFC 8950 refers to RFC 2545, which requires a GUA IPv6 next hop in BGP updates (well, it uses the SHALL wording, which usually means “troubles ahead”). What do you do if you’re running EBGP on an interface with no global IPv6 addresses? As expected, vendors do different things, resulting in another fun interoperability exercise.

Finally, there’s RFC 7404 that advocates LLA-only infrastructure links, so we might find the answer there. Nope; it doesn’t even acknowledge the problem in the Caveats section.

For even more information, read the Unnumbered IPv4 Interfaces and BGP in Data Center Fabrics blog posts.

IBM Will Catch A Piece Of The GenAI Wave With Next-Gen Systems

We don’t normally spend a lot of time writing about IBM mainframes, but these big iron systems drive a lot of transactions in the world – transactions flush with demographics and context that will feed into AI models – and will be doing native and integrated AI processing for the applications that push those applications. …

Recap: KubeCon + CloudNativeCon Europe 2025

When I got the assignment to attend KubeCon 1st of April I thought it was an April prank, but as the date got closer I realized—this is for real and I’ll be on the ground in London at the tenth anniversary of cloud native computing. I’ve seen a lot of tech events during my years in the industry while trying not to get replaced by AI and I have to say this one stands out!

Here is my recap of KubeCon + CloudNativeCon Europe 2025.

CalicoCon 2025

CalicoCon is an event that happens twice every year, as a co-located event during KubeCon NA and EU. It’s a free event that allows you to learn about Tigera’s vision for the future of networking and security in the cloud. There’s also an after-party to celebrate our community and people like you who are on this journey with us!

This year our main focus was on Calico v3.30, our upcoming release that will add a lot of anticipated features to Calico, unlocking things like observability, staged network policy, and gateway api. CalicoCon brought together cloud-native enthusiasts to explore the latest advancements in Calico and Kubernetes networking.

New year, no shutdowns: the Q1 2025 Internet disruption summary

Cloudflare’s network spans more than 330 cities in over 125 countries, where we interconnect with over 13,000 network providers in order to provide a broad range of services to millions of customers. The breadth of both our network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the impact of Internet disruptions at both a local and national level, as well as at a network level.

As we have noted in the past, this post is intended as a summary overview of observed and confirmed disruptions, and is not an exhaustive or complete list of issues that have occurred during the quarter. A larger list of detected traffic anomalies is available in the Cloudflare Radar Outage Center. Note that both bytes-based and request-based traffic graphs are used within the post to illustrate the impact of the observed disruptions — the choice of metric was generally made based on which better illustrated the impact of the disruption.

In the first quarter of 2025, we observed a significant number of Internet disruptions due to cable damage and power outages. Severe storms caused outages in Ireland and RĂŠunion, and an earthquake caused ongoing connectivity issues Continue reading
