Making FreeBSD QUIC - Tom Jones - EuroBSDcon 2022

The Internet has continued to evolve throughout its life and with these changes the protocols we use to move information around have had to adapt to keep up. TCP, the work horse of the Internet has reliably been delivering bytes for many decades, but the protocol lacks room to grow to meet future challenges. QUIC was created as a new protocol to enable future evolution in how we move bits around the Internet. QUIC adds always Authentication and Encryption, features that allow much improved congestion control, better features for CDN operators and higher reliability for end users. Once QUIC escaped into the IETF it followed an open development process, but other than Mac OS laptops for development, QUIC was mostly designed and tested on Linux systems. With this Linux focus we have to wonder if BSD platforms are being left behind? This talk looks at the performance of QUIC implementations on Linux and FreeBSD and explores the changes that made QUIC implementations faster. We will will dig into network performance and techniques that can used to understand the performance of any application on FreeBSD. With this we try to answer the question, How can we make FreeBSD QUIC?
