DNS at IETF 118

The IETF met in Prague in the first week of November 2023, and, as usual there was a flurry of activity in the DNS-related Working groups. Here's a roundup of those DNS topics I found to be of interest at that meeting.

Steve Bray: Why I joined Cloudflare

Steve Bray: Why I joined Cloudflare.

I am excited to announce that I joined Cloudflare last month as Head of Australia & New Zealand, to continue to build on Cloudflare’s success in the region through extending our valuable relationships with our customers and partners.

My journey to Cloudflare

I’ve been fortunate over my 25-year career in the IT industry to have worked for some of the most recognised and innovative organisations such as Oracle, Salesforce, and Zendesk. It’s been exciting to be inside these businesses as they’ve taken new ideas about how software can be developed and delivered to solve real world problems for any organisation’s customers. I’ve learned a lot by being a part of the industry, but probably more importantly, I’ve learned the most from the smart, experienced, diverse groups of talented people that I’ve had the pleasure to work with in ANZ and across Asia Pacific. I have always been interested in the problems that organisations are trying to solve through technology — for example, responding to strategic challenges, reducing cost, improving revenue, reducing risk — and joining Cloudflare is an opportunity to stay focussed on addressing those critical issues with our customers and partners using Cloudflare’s innovative solutions.

So why Cloudflare?

NB457: Broadcom, VMware Tie The Knot; Nvidia SuperNICs Target AI Ethernet Acceleration

Now that Broadcom’s $69 billion VMware acquisition is complete, will Broadcom invest more in VMware to compete in multi-cloud or settle for profitable revenue collection from existing customers? Nvidia debuts a SuperNIC designed to accelerate Ethernet to support AI workloads and announces partnerships with server makers to bundle its NIC in an AI Ethernet stack.... Read more »

Tech Bytes: Nokia Deepfield Brings Fresh Analytics, New Gear To The DDoS Fight (Sponsored)

Distributed Denial of Service attacks, or DDoS, have plagued the Internet for decades. And attackers are finding new ways to take advantage of higher levels of bandwidth and the ever-growing number of network-connected devices. Today on Tech Bytes, sponsored by Nokia, we’ll talk about what’s brewing on the DDoS front and how Nokia’s Deepfield is... Read more »

Cloudflare named a leader in Forrester Edge Development Platforms Wave, Q4 2023

This post is also available in Español, Deutsch, Português, 日本語, 한국어.

Forrester has recognized Cloudflare as a leader in The Forrester Wave™: Edge Development Platforms, Q4 2023 with the top score in the current offering category.

According to the report by Principal Analyst, Devin Dickerson, “Cloudflare’s edge development platform provides the building blocks enterprises need to create full stack distributed applications and enables developers to take advantage of a globally distributed network of compute, storage and programmable security without being experts on CAP theorem.“

Over one million developers are building applications using the Developer Platform products including Workers, Pages, R2, KV, Queues, Durable Objects, D1, Stream, Images, and more. Developers can easily deploy highly distributed, full-stack applications using Cloudflare’s full suite of compute, storage, and developer services.

Workers make Cloudflare’s network programmable

“ A key strength of the platform is the interoperability with Cloudflare’s programmable global CDN combined with a deployment model that leverages intelligent workload placement.”
– The Forrester Wave™: Edge Development Platforms, Q4 2023

Workers run across Cloudflare’s global network, provide APIs to read from and write directly to the local cache, Continue reading

Asking The Right Question About The Wireless Future

It wasn’t that long ago that I wrote a piece about how Wi-Fi 6E isn’t going to move the needle very much in terms of connectivity. I stand by my convictions that the technology is just too new and doesn’t provide a great impetus to force users to upgrade or augment systems that are already deployed. Thankfully, someone at the recent Mobility Field Day 10 went and did a great job of summarizing some of my objections in a much simpler way. Thanks to Nick Swiatecki for this amazing presentation:

He captured so many of my hesitations as he discussed the future of wireless connectivity. And he managed to expand on them perfectly!

New Isn’t Automatically Better

Any time I see someone telling me that Wi-Fi 7 is right around the corner and that we need to see what it brings I can’t help but laugh. There may be devices that have support for it right now, but as Nick points out in the above video, that’s only one part of the puzzle. We still have to wait for the clients and the regulatory bodies to catch up to the infrastructure technology. Could you imagine if we did the same Continue reading

Do hackers eat turkey? And other Thanksgiving Internet trends

Do hackers eat turkey? And other Thanksgiving Internet trends

Thanksgiving is a tradition celebrated by millions of Americans across six time zones and 50 states, usually involving travel and bringing families together. This year, it was celebrated yesterday, on November 23, 2023. With the Internet so deeply enmeshed into our daily lives, anything that changes how so many people behave is going to also have an impact on online traffic. But how big an impact, exactly?

At a high level: a 10% daily decrease in Internet traffic in the US (compared to the previous week). That happens to be the exact same percentage decrease we observed in 2022. So, Thanksgiving in the US, at least in the realm of Internet traffic, seems consistent with last year.

Let’s dig into more details about how people deal with cooking (or online ordering!) and whether family gatherings are less online, according to our Cloudflare Radar data. We’ll also touch on whether hackers stop for turkey, too.

The Thanksgiving hour: around 15:00 (local time)

While we can see a 10% overall daily drop in US traffic due to Thanksgiving, the drop is even more noticeable when examining traffic on an hour-by-hour basis. Internet activity began to decrease significantly after 12:00 EST, persisting Continue reading

RustRadio improved API 0.4

Since last time, I’ve improved the API a bit. That last post was about API version 0.3. Now it’s on 0.4, and I think it’s getting pretty decent.

0.3 could never have worked very well. The API was VecDeque-based, which means it could not provide a linear view (a slice) of all the data in the buffer.

The 0.4 API is simpler. You get a typed slice, and you read or write to, it as appropriate. Because all streams are currently single writer, single reader, the code is simple, and requires minimal amount of locking.

It’s simpler, but I switched to using memory mapped circular buffers, with a slice as the stream interface. This means that the buffer is allocated only once, yet both reader and writer can use all space available to them, linearly, without having to worry about wrapping around.

The code is still at https://github.com/ThomasHabets/rustradio. I registered the github org rustyradio, too. rustradio was taken. I sent a message to the owner, since it seems to not have any real content, but have not heard back.

Unsafe code

To make this multiuser stream I did have to write some Continue reading
