Dave Täht (born 1965) is an American computer scientist, musician, lecturer, asteroid exploration advocate, and Internet activist. He is the CEO of TekLibre, LLC.

Activity

Täht co-founded the Bufferbloat Project with Jim Gettys, ran the CeroWrt and Make-Wifi-Fast sub-projects, and referees the bufferbloat related mailing lists [1] and related research activities.

In the early stages of the Bufferbloat project he helped prove that applying advanced AQM and Fair Queuing techniques like (FQ-CoDel) to network packet flows would break essential assumptions in existing low priority congestion controls such as bittorrent and LEDBAT and further, that it didn't matter.[2]

His CeroWrt project [3] showed that advanced algorithms like CODEL, FQ-CoDel, and Cake were effective not only at low bandwidths but scaled to 10s of GB/s and could be implemented on inexpensive hardware and also helped make OpenWrt ready for IPv6 Launch Day.

His successor Make-Wifi-Fast project solved [4] the WiFi performance anomaly by extending FQ-Codel algorithm to work on multiple WiFi chips in Linux[5].

In order to complete the make-wifi-fast project, by co-authoring an FCC filing [6] and co-ordinating a worldwide protest with Vint Cerf and many other early Internet pioneers, Taht successfully fought proposed FCC rules [7] to prohibit the installation of 3rd party firmware on home routers.[8][9]

With a long running goal of one day building an internet with sufficiently low latency and jitter that "you could plug your piano into the wall and play with a drummer across town" [10], and a persistent and dedicated explainer of how the internet (and wifi) really work, with lectures at MIT [11], Stanford "Introduction to CoDel"., and other internet institutions such as APNIC. [12]

He has been intensely critical of the academic network research community, extolling open access, open source code and the value of negative and repeatable results. [13]

As one of the instigators of the IETF AQM and Packet Scheduling working group[14], he is the co-author of RFC8290 [15], and a contributor to RFC8289 [16] (CODEL), RFC7567 [17], RFC8034[18], RFC7928[19], RFC7806 [20], and RFC8033[21], and also made contributions to the DOCSIS 3.1 standard.

In 2018, with John Gilmore, and Paul Wouters, he began the IPv4 Unicast Extensions Project[22]. Their Internet drafts proposing allowing unicast use of up to 419 million new IPv4 addresses from the formerly reserved Class E (240/4), 0/8, and the zeroth addresses were presented at the IETF 110 conference [23].

He is a filksinger, often performing songs like "It GPLs me"[24], and "One First Landing" at various computer and science fiction conventions.

He serves on the Commons Conservancy[25] board of directors.
