Dave Täht (born August 11, 1965) is an American network engineer, musician, lecturer, asteroid exploration advocate, and Internet activist. He is the chief executive officer of TekLibre.
Activity
[edit]Täht co-founded the Bufferbloat Project with Jim Gettys, runs the CeroWrt and Make-Wifi-Fast sub-projects, and referees the bufferbloat related mailing lists[1] and related research activities.
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",[2] he is a persistent and dedicated explainer of how queues across the internet (and wifi) really work, lecturing at MIT,[3] Stanford,[4] and other internet institutions such as APNIC.[5]
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.[6]
His CeroWrt project[7] showed that advanced algorithms like CoDel, FQ-CoDel, DOCSIS-PIE and Cake were effective at reducing network latency, at no cost in throughput[8] not only at low bandwidths but scaled to 10s of GB/s and could be implemented on inexpensive hardware. CeroWrt project members also helped make OpenWrt ready for IPv6 Launch Day, and pushed all the innovations back into open source.
His successor Make-Wifi-Fast project solved[9] the WiFi performance anomaly by extending the FQ-Codel algorithm to work on multiple WiFi chips in Linux,[10] reducing latency under load by up to a factor of 50.
FQ-CoDel has since become the default network queuing algorithm for Ethernet and Wi-Fi in most Linux distributions, and on iOS, and OSX. It is also widely used in packet shapers. Comcast also successfully rolled out the DOCSIS-PIE AQM during the COVID crisis[11] with observed 8-16x reductions in network latency under load across the millions of user devices tested.
In order to complete the make-wifi-fast project, by co-authoring an FCC filing[12] and co-ordinating a worldwide protest with Vint Cerf, and many other early Internet pioneers, Taht successfully fought proposed FCC rules[13] to prohibit the installation of 3rd party firmware on home routers.[14][15]
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.[16]
As one of the instigators of the IETF AQM and Packet Scheduling working group,[17] he is the co-author of RFC8290,[18] and a contributor to RFC8289[19] (CODEL), RFC7567,[20] RFC8034,[21] RFC7928,[22] RFC7806,[23] and RFC8033.[24] He also made contributions to the DOCSIS 3.1 standard.
He is a filksinger, often performing songs like "It GPLs me",[25] and "One First Landing" at various computer and science fiction conventions.
He serves on the Commons Conservancy[26] board of directors.
