Top500 Supers: Even Accelerators Can’t Bend Performance Up To The Moore’s Law Line was written by Timothy Prickett Morgan at The Next Platform.
Did you know that there’s an Ethernet link between the Packet Forwarding Engine (PFE – data plane) and Routing Engine (RE – control plane) in every Juniper MX? That’s why you have to run two VMs to emulate it (sometimes conveniently packed into one larger VM, proving RFC 1925 rule 6a).
That Ethernet link happens to have the MTU fixed at 1500 bytes. Guess what happens in the world where everyone uses jumbo frames? Did you say fragmentation? Bingo! And what do you think happens when one of those fragments gets dropped due to control-plane policing, and the rest of them are stuck in the reassembly queue? You’ll find the gory details in a lengthy blog post by Nitzan Tzelniker.
After three relatively short years of explosive growth thanks to the GenAI boom, AI is driving half of systems revenues worldwide already. …

Note: Grafana Cloud has a free service tier that can be used to test this example.
We all write code, but how do we know the changes we make in the future won’t break something that used to work? That’s where testing becomes important.
The idea is to catch problems early, ideally before they reach production. In the Python world, one of the most common ways to do this is with a tool called pytest. It lets you write tests to check that your code behaves the way you expect and helps you catch issues before they become a bigger problem.

When working with Infrahub, testing is just as important. You might want to make sure your GraphQL queries are valid, your Jinja2 templates render correctly, or your transformations behave as expected.
Infrahub simplifies this by offering a pytest plugin that doesn’t require Python code; you define tests using plain YAML. This makes testing more accessible to teams across roles and speeds up the feedback loop during development.
These kinds of unit tests aren’t just about convenience, they help establish a production-ready automation system. With automated checks built into your process, every change is validated consistently, reducing the chance of something breaking unexpectedly. That consistency builds trust when your Continue reading
I got an interesting question from a reader. He listened to my podcast with Eric Chou and decided to try to learn in public:
Currently, I’m studying for the CCNP ENARSI exam, and would like to start posting my labs to LinkedIn, and perhaps even upload my lab topologies and configs to Git.
That’s a great idea. I would minimize the LinkedIn part1 and focus on Git:
This guide walks you through installing and configuring the ELK Stack (Elasticsearch, Logstash, Kibana, and Filebeat) using Docker Compose. It is fully updated for Elasticsearch 9.0.2 and explains the necessary changes for versions 8+ and above, including the required security setup and user permissions. Prerequisites Ensure you have the following installed on your system: The […]

TL;DR - For anyone who doesn’t want to go through the full post, here’s the short version. I bought the UGreen NASync DXP2800 (2 bay) from Amazon for £249 and paired it with two Seagate Ironwolf 8TB HDDs, around £180 each.
The unit comes with an Intel N100 CPU, 8GB of RAM (upgradeable to 16GB, but there’s only one RAM slot), and a 2.5Gb/s LAN port. It has a solid build, was easy to set up, and I actually like the UI. Sure, it lacks a lot of features compared to Synology or QNAP, but since I’m mainly using it for file storage, I’m happy with the purchase.

The short answer is, this is the best bang for the buck. For £249, I’m getting a 2-bay NAS with an N100 CPU, 8GB of RAM, a 2.5Gb/s LAN port, and two NVMe slots.
I’ve been wanting to buy a NAS for over Continue reading
Password hygiene drives IT professionals crazy–people forget their passwords, will not change them often enough, and choose weak ones. But are IT folks immune to these problems? What is the psychology behind passwords, and how do we do better? Karl Buhl joins Tom and Russ to talk about passwords.

Unsurprisingly, the main topic of conversation at the recent Dell Technologies World 2025 event in Las Vegas was AI, and a central theme that wove through many of the messages we heard there was that adopting the emerging technology is much easier now than it was even a year ago. …
Dell’s Advice To Enterprises: Buy AI, Don’t Try To Build It was written by Jeffrey Burt at The Next Platform.
We know there are three main ways to move packets across a network. However, before we can start forwarding packets, someone has to populate the forwarding tables in the intermediate devices or build the sequence of nodes to traverse in source routing.
Usually, whoever is responsible for the contents of the forwarding tables must first discover the network topology. Let’s start there, using the following network diagram to illustrate the discussion.
If you follow me or read my blog, you probably know I'm a big advocate of Containerlab. I've been using it for over two years now and I absolutely love it. Why? Because it's open source, it has an amazing community behind it (thank you again, Roman), and labs are defined using simple YAML files that are easy to share and reuse.
So far, I've used Cisco IOL, Arista EOS, and Palo Alto VM in Containerlab. And finally, the time came to try Juniper. I decided to test the Juniper vJunos-router, which is a virtualized MX router. It's a single-VM version of vMX that doesn't require any feature licenses and is meant for lab or testing purposes. You can even download the image directly from Juniper's website without needing an account. Thank you, Juniper and Cisco, please take note. In this post, I'll show you how to run Juniper vJunos-router in Containerlab.
This post assumes you're somewhat familiar with Containerlab and already have it installed. If you're new, feel free to check out my introductory blog below. Containerlab also has great documentation on how to use vJunos-router, so be sure to check that out as well.
