Rearchitecting the TCP Stack for I-O-Offloaded Content Delivery

Explore a groundbreaking approach to enhancing online content delivery performance in this 17-minute conference talk from NSDI '23. Delve into the innovative IO-TCP design, which rearchitects the TCP stack to offload disk I/O and TCP packet transfer to SmartNIC, significantly reducing CPU burden. Learn how this split TCP stack design separates control and data planes, allowing the CPU to maintain full control while leveraging SmartNIC for high-performance data plane operations. Discover the impressive results of this approach, including how IO-TCP-ported lighttpd outperforms traditional servers in TLS file transfer, even with fewer CPU cores. Gain valuable insights into the future of scalable content delivery and the potential for optimizing high-bandwidth I/O devices in server architectures.
