Running Code
There was a discussion in a working group session at the recent IETF 111 meeting over a proposal that the working group should require at least two implementations of a draft before the working group would consider the document ready. What's going on here?kOps adds support for Calico’s eBPF data plane
Kubernetes operations (kOps) is one of the official Kubernetes (K8s) projects. The kOps project allows for rapid deployment of production-grade K8s clusters in multiple cloud platforms. By leveraging yaml manifests, kOps delivers a familiar experience to users who have worked with kubectl. Similar to K8s clusters in popular cloud platforms, kOps helps set up self-managed clusters to easily deliver high availability. Given its ease of use, it is a very popular choice when users want to deploy self-hosted Kubernetes clusters.
With the recent release of kOps (v1.19), support for the Calico eBPF data plane was added to the utility. In addition to the above-mentioned features, the latest kOps update offers an effortless way to autodeploy K8s clusters utilizing Project Calico for networking and the Calico eBPF data plane. Calico eBPF data plane implementation replaces kube-proxy and delivers equivalent functionality; it also leverages the most optimal datapath for traffic. These changes deliver a network performance boost and source IP preservation to your cluster.
In this blog post, we will showcase the steps required to deploy a cluster that utilizes these newly available features.
What is eBPF?
eBPF is a virtual machine embedded within the Linux kernel. Continue reading
Intel Finally Gets Chiplet Religion With Server Chips

Building a Pet Cam using a Raspberry Pi, Cloudflare Tunnels and Teams
I adopted Ziggy in late 2020. It took me quite a while to get used to his routine and mix it with mine. He consistently jumped on the kitchen counter in search of food, albeit only when no one was around. And I only found out when he tossed the ceramic butter box. It shattered and made a loud bang in the late hours of the night. Thankfully, no one was asleep yet.
This got me thinking that I should keep an eye on his mischievous behaviour, even when I'm not physically at home. I briefly considered buying a pet cam, but I remembered I had bought a Raspberry Pi a few months before. It was hardly being used, and it had a case (like this) allowing a camera module to be added. I hadn’t found a use for the camera module — until now.
This was a perfect weekend project: I would set up my own pet cam, connect it to the Internet, and make it available for me to check from anywhere in the world. I also wanted to ensure that only I could access it and that it had some easy way to login, possibly using Continue reading
Cloudflare thwarts 17.2M rps DDoS attack — the largest ever reported
Earlier this summer, Cloudflare’s autonomous edge DDoS protection systems automatically detected and mitigated a 17.2 million request-per-second (rps) DDoS attack, an attack almost three times larger than any previous one that we're aware of. For perspective on how large this attack was: Cloudflare serves over 25 million HTTP requests per second on average. This refers to the average rate of legitimate traffic in 2021 Q2. So peaking at 17.2 million rps, this attack reached 68% of our Q2 average rps rate of legitimate HTTP traffic.
Automated DDoS mitigation with Cloudflare’s autonomous edge
This attack, along with the additional attacks provided in the next sections, were automatically detected and mitigated by our autonomous edge DDoS protection systems. The system is powered by our very own denial of service daemon (dosd). Dosd is a home-grown software-defined daemon. A unique dosd instance runs in every server in each one of our data centers around the world. Each dosd instance independently analyzes traffic samples out-of-path. Analyzing traffic out-of-path allows us to scan asynchronously for DDoS attacks without causing latency and impacting performance. DDoS findings are also shared between the Continue reading

Hedge 96: Mark Nottingham and the Future of Standardization
It often seems like the IETF is losing steam—building standards, particularly as large cloud-scale companies a reducing their participation in standards bodies and deploying whatever works for them. Given these changes, what is the future of standards bodies like the IETF? Mark Nottingham joins Tom Ammon and Russ White in a broad-ranging discussion around this topic.
