Roadwarrior: Surge 2010, NANOG 50, and OpenBFDD

Last week, I attended the Surge Conference in Baltimore, MD. The conference was put together by the great folks over at OmniTI Computer Consulting, and focused on web scalability and performance. The speaker lineup was simply amazing; Theo pulled in experts from numerous large scale web production companies, including Facebook, Etsy, LinkedIn, and Wikia. Many of the presentations focused on design patterns at scale, reminding some of us that we keep making the same architecture mistakes over and over.

Other talks focused on improvements to existing open source software projects, and other commonly used infrastructure pieces. I even had the opportunity to present and demystify anycast for Surge attendees.

This week, I’m at NANOG 50 in Atlanta, GA. Like every other NANOG, we’re here to learn about the latest and greatest networking developments, from hardware to network protocols, and everything in between. There were two real gems in the agenda today: Geoff Huston’s talk on IPv6 Background Radiation, and the TRILL vs. 802.1aq panel. As IPv6 becomes more widely deployed, it is nice to see many of the benefits of having a wide network prefix space being available. With regards to TRILL and 802.1aq, I’m just glad to see that spanning tree protocol will be something we all can extricate from our networks in the near future. Tomorrow promises to bring a number of exciting talks to the agenda as well.

Something in common from Surge and NANOG 50 is Dyn’s proud announcement of OpenBFDD, an open-sourced implementation of the Bidirectional Forwarding Detection (BFD) protocol. We’ve been using BFD within Dyn’s network for some time now, and when we decided we wanted to run BFD directly to some of our edge boxes, we needed something that could run on top of FreeBSD. In typical Dyn fashion, our engineering team got to work, and developed OpenBFDD and bfd-beacon. Today, we’re happy to announce open source availability of this work at our GitHub site:

Summary: If you were at Surge 2010 and we somehow missed you, please drop us a tweet so we can connect. If you’re at NANOG 50, come find one of us to chat with so we can tell you why DNS IS SEXY. If you’re a routing and networking geek like myself, take some time and go check out OpenBFDD.
