Reducing Network Latency: Innovations for a Faster Internet

Explore how to make the internet faster by eliminating unnecessary latency in this 45-minute conference talk recorded at GOTO Chicago 2024. Dave Taht, who has dedicated over 15 years to reducing network latency, shares his expertise on pioneering network algorithms like CAKE and fq_codel, and their implementation in OpenWrt and Linux. Learn about the fundamentals of congestion control, bufferbloat solutions, TCP windows, and smart queue management through demonstrations and technical explanations. The presentation covers critical concepts including TCP's slow start mechanisms, congestion avoidance algorithms, the TCP Reno/Cubic sawtooth pattern, and practical approaches to keeping queues short. With real-world examples comparing different network implementations and a substantial Q&A session, gain valuable insights into creating smarter, more efficient networks for ISPs and beyond.
