Reducing Network Latency: Innovations for a Faster Internet • Dave Taht • GOTO 2024

This presentation was recorded at GOTO Chicago 2024. #GOTOcon #GOTOchgo https://gotochgo.com Dave Taht - Truly Speeding up the Net, One Smart ISP at a Time @davetaht4989 RESOURCES https://twitter.com/mtaht https://www.linkedin.com/in/dtaht https://github.com/dtaht https://blog.cerowrt.org Links https://www.bufferbloat.net ABSTRACT Dave Taht has spent over 15 years dedicated to one mission: making the internet faster by eliminating unnecessary latency. From pioneering network algorithms like CAKE and fq_codel to contributing to key standards organizations and implementing solutions in OpenWrt and Linux, Dave has driven significant progress in optimizing network performance. In this talk, Dave will share insights into his work on latency reduction, network theory, and packet capture analysis. Get a deeper understanding of the challenges and breakthroughs in creating smarter, more efficient networks, as well as the practical applications of these innovations for ISPs and beyond.
