HexaMesh: Chiplet Topologies Inspired By Nature

With the reticle limit for chip manufacturing pretty much set in stone (pun intended) at 26 millimeters by 33 millimeters down to 2 nanometer transistor sizes with extreme ultraviolet lithography techniques and being cut in half to 26 millimeters by 16.5 millimeters for the High-NA extreme ultraviolet lithography needed to push below 2 nanometer transistor sizes, chiplets are inevitable and monolithic dies are absolutely going to become a thing of the past. …

User Discomfort As A Security Function

If you grew up in the 80s watching movies like me, you’ll remember Wargames. I could spend hours lauding this movie but for the purpose of this post I want to call out the sequence at the beginning when the two airmen are trying to operate the nuclear missile launch computer. It requires the use of two keys, one each in the possession of one of the airmen. They must be inserted into two different locks located more than ten feet from each other. The reason is that launching the missile requires two people to agree to do something at the same time. The two key scene appears in a number of movies as a way to show that so much power needs to have controls.

However, one thing I wanted to talk about in this post is the notion that those controls need to be visible to be effective. The two key solution is pretty visible. You carry a key with you but you can also see the locks that are situated apart from each other. There is a bit of challenge in getting the keys into the locks and turning them simultaneously. That not only shows that the Continue reading

Simplify Kubernetes Hosted Control Planes with K0smotron

Multicluster Kubernetes gets complicated and expensive fast — especially in dynamic environments. Private cloud multicluster solutions need to wrangle a lot of moving parts: Private or public cloud APIs and compute/network/storage resources (or bare metal management) Linux and Kubernetes dependencies Kubernetes deployment etcd configuration Load balancer integration And, potentially other details, too. So they’re fragile — Kubernetes control planes on private clouds tend to become “pets” (and not in a cute way). Multicluster on public clouds, meanwhile, hides some of the complexity issues (at the cost of flexibility) — but presents challenges like cluster proliferation, hard-to-predict costs, and lock-in. What Are Hosted Control Planes (HCPs)? Kubecon Hosted Control Planes (HCPs) route around some (not all) of these challenges while bringing some new challenges. An HCP is a set of Kubernetes manager node components, running in pods on a host Kubernetes cluster. HCPs are less like “pets” and more like “cattle.” Like other Kubernetes workloads, they’re defined, operated, and updated in code (YAML manifests) — so are repeatable, version-controllable, easy to standardize. But worker nodes, as always, need to live somewhere and networked to control planes, and there are several challenges here. They gain basic resilience from Kubernetes itself: if Continue reading

NB 469: Arista Debuts Network Observability Service; Startups Aim To Break Nvidia’s AI Chip Grip

This week we discuss a new network observability offering from Arista that integrates network telemetry with application data, why startups such as Groq and Taalas think they can break Nvidia’s grip on the AI chip market, and how Microsoft is hedging its LLM bets. Amazon goes nuclear with the purchase of a reactor-powered data center... Read more »

Security Week 2024 wrap up

The next 12 months have the potential to reshape the global political landscape with elections occurring in more than 80 nations, in 2024, while new technologies, such as AI, capture our imagination and pose new security challenges.

Against this backdrop, the role of CISOs has never been more important. Grant Bourzikas, Cloudflare’s Chief Security Officer, shared his views on what the biggest challenges currently facing the security industry are in the Security Week opening blog.

Over the past week, we announced a number of new products and features that align with what we believe are the most crucial challenges for CISOs around the globe. We released features that span Cloudflare’s product portfolio, ranging from application security to securing employees and cloud infrastructure. We have also published a few stories on how we take a Customer Zero approach to using Cloudflare services to manage security at Cloudflare.

We hope you find these stories interesting and are excited by the new Cloudflare products. In case you missed any of these announcements, here is a recap of Security Week:

KeyTrap!

Yet another DNS vulnerability has been exposed. The language of the press release revealing the vulnerabil;ity is certainly dramatic, with "devasting consequences" and the threat to "completely disable large parts of the worldwide Internet."" If this is really so devastating then perhaps we should look at this in a little more detail to see what’s going on, how this vulnerability works, and what the response has been.

The Future of Network Engineering in the AI/ML era

It seems like yesterday when I saw my first network automation presentation at a conference. I remember it very well; it was in 2015 at the Cisco Network Innovation Summit in Prague. Mr. Tim Szigeti was presenting the first version of the Cisco APIC-EM, the future Cisco Digital Network Architecture (DNA) controller. I talked already about it in a previous article, written in 2018, about my journey toward network programmability and automation. After its presentation, and for many years afterward, the question was on everyone’s lips: Is this the end…

Slurp’it – Network Inventory & Discovery Tool

Slurp'it - Network Inventory & Discovery Tool

I recently came across a neat tool called 'Slurp'it', a Network Inventory and Discovery solution. If you've been following my blog for a while, you know I just had to give it a try and share my findings with you. So, in this post, I'm going to quickly go over how to get it up and running, along with a few ways you might find it useful. Let's dive in.

What We Will Cover?

  • What is Slurp'it?
  • Licenses
  • Installation and Setup
  • Data Collection
  • Custom Planning
  • Some Use Cases

What is Slurp'it?

The official definition is "Slurp’it is a powerful and easy-to-use network discovery solution that offers 100% accurate network inventory. No coding required." Out of the box, the tool supports almost all the vendors (117 as of writing this)

In a nutshell, Slurp'it simplifies the whole process of understanding your network's inventory. All you need to do is provide the IP address or hostname of your devices, along with the login credentials. Slurp'it takes it from there. It executes various 'show' commands on your devices, usesTextFSM to parse the outputs, and finally presents you with a tidy table detailing everything it has discovered. It's straightforward yet effective, Continue reading

Worth Reading: Talent Gap in IT

If you need a good rant about Thought Leaders, Talent Gap, and Certification-Based-Hiring, look no further than I see a different gap from here!. Here’s a choice tidbit:

Every single job description that requires some sort of certification must be treated with suspicion. Demanding a certification usually means that you don’t know what you want, and you’re just outsourcing your thinking to someone else.

Have fun!

Worth Exploring: PCAP Analysis with Generative AI

John Capobianco published the source code of his Packet Buddy application on GitHub. It’s a Python UI that takes a PCAP file, converts it to JSON, and includes that JSON as part of the ChatGPT chat, allowing you to discuss the captured packets with ChatGPT.

His idea is one of the best uses of generative AI in networking I’ve seen so far, as long as you remember that you’re dealing with an overconfident intern who has no problem making up an answer just to sound smart. Have fun!

Finally, if you don’t want to use ChatGPT (I wouldn’t blame you) or send captured data into The Cloud, someone already adapted his idea to use local LLMs.

Hedge 216: Automation Success Stories

One thing we often hear about automation is that its hard because there are so many different interfaces. On this episode of the Hedge, Daniel Teycheney joins Ethan Banks and Russ White to discuss how they started from a simple idea and ended up building an automation system that does cross vendor boundaries within a larger discussion about automation and APIs.
