Celebrating the Internet Measurement 'C'ommunity!
Coinciding with the ACM’s Internet Measurement Conference, the Cloudflare Research team is publishing a series of posts this week to share our research on building a more measurable, resilient, and transparent Internet. cfl.re/49k9fVY #CloudflareResearch
New TCP resets and timeouts dataset on Cloudflare Radar surfaces connection tampering, scanning, DoS attacks, and more. cfl.re/4dNqlLt
@Cloudflare Very proud to have worked on this with @ramakrishnan13s @marwanfayed @DistributedDave @kkevsterrr @henri_merino @grittygrease and many others
🎉 Join us for a special segment celebrating 50 years of the “TCP paper”! Our experts dive into why TCP is crucial for the Internet’s evolution and its future. Featuring @mnot, @marwanfayed, and @SimmerVigor. Don’t miss it! #TCP #Internet 🌐✨ cfl.re/4aN6BFk
Congrats to the winners! ANRP helps bridge two communities that advance state of the art with two different consensus processes. A wide-subject and engaging set of nominees this year. One can only imagine the things that 2024 will bring.
Six researchers have been announced as new #ANRP awardees this year for recent results in applied networking research and interesting new research of potential relevance to the Internet standards community. Read about the wide range of topics at: ietf.org/blog/anrp-2023/
Helping to widen the conversation on IP blocking. The Internet Protocol was visionary, built on sound principles and experience. By design, IP addresses establish reachability, never identity. IP address blocking does harm, even threatens human rights. cfl.re/3V2rZP9
@micahlerner Wow, this is an honour. We're happy to "talk shop" anytime, Micah. Thanks!
This week's paper is "The Ties that un-Bind: Decoupling IP from web services and sockets for robust addressing agility at CDN-scale": micahlerner.com/2022/01/13/the… It describes how Cloudflare change its CDN to reduce IP address usage (which turned out to provide many other benefits!)
Looking ahead to post-quantum-safe TLS! Also a reminder that congestion control is subtle, powerful, well-tuned... and still a hot research topic after 40 years. "Respect!"
How much room does TLS have for the big post-quantum signatures? We had a look: it’s tight. cfl.re/3CWVlWW
@liu_zhiyong Hello, @liu_zhiyong -- thanks for asking. Here you go! blog.cloudflare.com/tag/privacy/ . I'm told more languages are on the way, too.
@realhamed @convoluted_code @brave Great news! Congrats, Both!
Today's blog post by @GVasilis and @marwanfayed goes into detail about just how good this guess can be. The results show that Cloudflare has the lowest latency globally of any CDN. And now anyone can validate that claim without running a single scan. blog.cloudflare.com/look-ma-no-pro…
Spaces open for PhD research interns, too! blog.cloudflare.com/kicking-off-cl…
This post by interns Nate Sales and Alex Chen explains how we combine our knowledge of the Internet from public datasets with device-reported information to inform other teams at Cloudflare which source IPs are single-user and which are multi-user. blog.cloudflare.com/multi-user-ip-…
@johnspurlock @grittygrease @GVasilis Thanks for asking, @johnspurlock! We want to keep the focus of this blog on the technique. The one image is complete. Also, much like a mean or median, is one view of many interesting observations. Technical details are being prepared for peer review, with fuller results. Soon!
@Ignactro @ACM_IMC2021 @ietf @lumisota @csperkins @Gareth_Tyson @mpurver @Pat_Healey @waleediqbal411 @junaidq @GSmaragdakis has it right - respect, indeed! Really looking forward to reading it, and hope that it makes the IETF rounds, too.
Happy to share that I worked on these connection coalescing experiments as a Cloudflare intern this year with some amazing colleagues (@SulemanAhmadd, Jonathan Hoyland) and mentors (@grittygrease, @marwanfayed) :)
This is cool. We added cdnjs on the certificate for four thousand sites that use it, and gave them a single IP to see how connections would be reused. We saw 78% fewer TLS connections to cdnjs, which means lower CPU cost and better privacy. Oddly, no clear page load time boost.
@dwragg thanks! Also, am happy to recommend Jon and @MelissaAmaya32 to any potential interviewees.
This is a fascinating two-part interview with @marwanfayed from Cloudflare's research team. More podcasts that interview my colleagues please!
Even more from #CloudflareResearch🔬 today. This time we have a deep dive into our paper at ACM SIGCOMM about disentangling the mess of conventions around IP addresses, hostnames, and sockets. Plus, two posts about the future of our "favorite" authentication mechanism: passwords.
