Cloudflare’s global network handles a lot of HTTP requests – over 60 million per second on average. That in and of itself is not news, but it is the starting point to an adventure that started a few months ago and ends with the announcement of a new open-source Rust crate that we are using to reduce our CPU utilization, enabling our CDN to handle even more of the world’s ever-increasing Web traffic.
Let’s start at the beginning. You may recall a few months ago we released Pingora (the heart of our Rust-based proxy services) as an open-source project on GitHub. I work on the team that maintains the Pingora framework, as well as Cloudflare’s production services built upon it. One of those services is responsible for the final step in transmitting users’ (non-cached) requests to their true destination. Internally, we call the request’s destination server its “origin”, so our service has the (unimaginative) name of “pingora-origin”.
One of the many responsibilities of pingora-origin is to ensure that when a request leaves our infrastructure, it has been cleaned to remove the internal information we use to route, measure, and optimize traffic for our customers. This has to be Continue reading
This article describes the steps needed to emulate realistic network performance problems using Containerlab. First, using the FRRouting (FRR) open source router to build the topology provides a lightweight, high performance, routing implementation that can be used to efficiently emulate large numbers of routers using the native Linux dataplane for packet forwarding. Second, the containerlab tools netem set command can be used to introduce packet loss, delay, jitter, or restrict bandwidth of ports.
The netem tool makes use of the Linux tc (traffic control) module. Unfortunately, if you are using Docker desktop, the minimal virtual machine used to run containers does not include the tc module.

I’ll talk about the BGP labs and the magic behind the scenes that ensures the lab configurations are correct at the SINOG 8 meeting later today (selecting the English version of the website is counter-intuitive; choose English from the drop-down field on the right-hand side of the page).
The SINOG 8 presentations will be live-streamed; I should start around 13:15 Central European Time (11:15 GMT; figuring out the local time is left as an exercise for the reader).
Today, we are excited to announce a preview of improved Node.js compatibility for Workers and Pages. Broader compatibility lets you use more NPM packages and take advantage of the JavaScript ecosystem when writing your Workers.
Our newest version of Node.js compatibility combines the best features of our previous efforts. Cloudflare Workers have supported Node.js in some form for quite a while. We first announced polyfill support in 2021, and later built-in support for parts of the Node.js API that has expanded over time.
The latest changes make it even better:
You can use far more NPM packages on Workers.
You can use packages that do not use the node: prefix to import Node.js APIs
You can use more Node.js APIs on Workers, including most methods on async_hooks, buffer, dns, os, and events. Many more, such as fs or process are importable with mocked methods.
To give it a try, add the following flag to wrangler.toml, and deploy your Worker with Wrangler:
compatibility_flags = ["nodejs_compat_v2"]
Packages that could not be imported with nodejs_compat, even as a dependency of another package, will now load. This Continue reading

At this point, ChatGPT—or any Large Language Model (LLM)—needs no introduction. I’ve been exploring GPTs with relative success, and I’ve found that API interaction makes them even more effective.
But how can we turn this into a workflow, even a simple one? What are our use cases and advantages? For simplicity, we’ll use the OpenAI API rather than open-source, self-hosted LLMs like Meta’s Llama.
Let’s consider an example: searching for all OSPF-related RFCs on the web. Technically, we’ll use a popular search engine, but to do this programmatically, I’ll use Serper. You can find more details at https://serper.dev. Serper is a powerful search API that allows developers to programmatically access search engine results. It provides a simple interface to retrieve structured data from search queries, making it easier to integrate search functionality into applications and workflows.
Let’s build the first building block and try to fetch results using Serper. When you sign Continue reading
Hi all, welcome back to part 4 of the Network CI/CD blog series. So far, we've covered the purpose of a Network CI/CD pipeline, the problems it solves for Network Engineers, and how to set up GitLab, including creating projects, installing runners, and understanding GitLab executors. We also looked at how to use GitLab variables to securely hide secrets.
In this part, we'll explore how to manage a campus network using Nornir and Napalm and deploy configurations through a CI/CD pipeline. Let's get to it!

As I mentioned previously, I'm not a CI/CD expert at all and I'm still learning. The reason for creating this series is to share what I learn with the community. The pipeline we are building is far from perfect, but that's okay. The goal here is to create a simple pipeline that works and then build upon it as we go. This way, you can start small and gradually Continue reading
Welcome to Technology Short Take #182! I have a slightly bulkier list of links for you today, bolstered by some recent additions to my RSS feeds and supplemented by some articles I found through social media. There should be enough here to keep folks entertained this weekend—enjoy!

That’s just one of the unexpected tidbits I discovered when explaining why you can’t compare BGP, EVPN, and SRv6.

Hi all, welcome back to our Network CI/CD blog series. In the previous posts, we covered what CI/CD is and why you need it for Network Automation. We also covered GitLab basics and how to set up your first pipeline. In this post, we’ll look into how to keep your credentials secure by hiding them from the repository and using GitLab variables. Let’s get to it!
In GitLab CI/CD, variables play an important role in managing dynamic values throughout your pipeline. These variables can store anything from environment-specific settings to sensitive information like credentials. By using variables, you can easily manage and change values without hardcoding them in your scripts or playbooks.
GitLab provides a secure way to store sensitive data such as passwords or API tokens. You can define these variables in your project’s Settings > CI/CD > Variables section, and they will be securely injected into your pipeline during runtime.
If you recall, in our previous examples, we had the username and password hardcoded in the Ansible variables file. This is not secure at all, and you should never expose sensitive information like credentials directly in your repository. By using GitLab variables, you can securely Continue reading
