Dave Taht

Biography:

Jim Gettys and Dave Taht founded The Bufferbloat project in 2010 to explore why modern data networks became so slow when loaded. They set out to examine the literature and code, from the earliest days of the Internet to today, to try and find out what had gone wrong and ways to fix it.

The result of that effort (so far!) has been a renaissance in interest in congestion control and huge - orders of magnitude - improvements in network latency along the edge of the Internet, with new algorithms and code now deployed widely in Linux, Apple, and in multiple edge routing platforms. Surprisingly, we also made significant improvements in simultaneous bidirectional goodput.
Dave was the architect of the CeroWrt reference home router project, which was a testbed for Fair Queueing, AQM, and packet scheduling algorithms that anyone can use, in anything, to reduce the impact of network queuing delays on networked applications. It also tackled home router security and IPv6 issues. Work from the cerowrt project (notably fq_codel) is now the default in mainline Linux, and the CAKE shaper is now becoming the standard in most aftermarket router firmware and appearing in new products daily.

Previously, he worked extensively on VOIP technologies and embedded Linux on handhelds and cable set-top boxes. He was involved in the very early days of wifi, ran network operations in multiple ISPs and service providers, and founded three companies along the way.
After IETF standardized some of the results from the Bufferbloat effort (RFC8290, RFC8289), his present research is on speeding up modern wireless technologies such as 802.11ad and Wifi7 and 8. Last year, he co-founded a company developing latency and network monitoring middleboxes for ISPs, called LibreQos, leveraging CAKE.

For fun, he surfs, sails, and designs spacecraft. He spends excessive time in a hammock, thinking up new ways to annoy academia and industry into helping make the Internet faster and better for everyone.
