The CeroWrt project 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.

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 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.[1]

The CeroWrt project 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.

The make-wifi-fast project solved <ref=endinganomaly>Høiland-Jørgensen, T.; et al. "Ending the Anomaly: Achieving Low Latency and Airtime Fairness in WiFi". Proceedings of the 2017 USENIX Annual Technical Conference. USENIX ATC '17 July 12-14, 2017, Santa Clara, CA, USA. pp. 139–151.</ref> the WiFi performance anomaly and the FQ-Codel work on multiple WiFi chips in Linux.

During the make-wifi-fast project, co-authoring a filing with Vint Cerf and many other early Internet pioneers, he successfully fought proposed FCC rules [2] to prohibit the installation of 3rd party firmware on home routers.[3]Cite error: A <ref> tag is missing the closing </ref> (see the help page)., and a persistent and dedicated explainer of how the internet (and wifi) really work, with lectures at MIT, Stanford "Introduction to CoDel". {{cite web}}: Missing or empty |url= (help), and other internet institutions such as APNIC. [4]

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. [5]

As one of the instigators of the IETF AQM and Packet Scheduling working group[6], he is the co-author of RFC8290 [7], and a contributor to RFC8289 [8] (CODEL), RFC7567 [9], RFC8034[10], RFC7928[11], RFC7806 [12], and RFC8033[13], 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[14]. Their Internet drafts proposing allowing unicast use of the formerly reserved Class E (240/4), 0/8, and the zeroth addresses were presented at the IETF 110 conference [15]

He is a filksinger, often performing songs like "It GPLs me"<ref name="gplsme">"It Gpl's me"., and "One First Landing" at various computer and science fiction conventions.

He serves on the Commons Conservancy board of directors.
