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. [...]
