Serving Netflix Video Traffic at 400Gb-s and Beyond

This presentation will focus on the optimizations made by Netflix and the FreeBSD project which allow Netflix Open Connect to serve over 700Gb/s of Netflix video from a single CDN server. Learn how optimizations, including asynchronous sendfile, kernel TLS (kTLS), and inline hardware kTLS offload allows Netflix to be one of the most efficient content delivery networks. Attendees will also hear about performance results taken from production and experimental servers.
