Is TCP - at 44 - too old, slow and has bad habits that cant be fixed? Does shaving a few milliseconds of latency on a web transaction matter that much to call out for a new transport? The new kid on the block, QUIC thinks so. QUIC has been globally deployed at Google on thousands of servers. If you are running chrome as a browser and using YouTube, you are likely using QUIC. Estimates are 7% of the internet traffic is now QUIC.

In this talk Jana Iyengar and Ian Swett will provide an overview of QUIC, its motivations and the performance improvements observed at Google. They will discuss performance bottlenecks in Linux kernel UDP that were seen at Google's servers, what was done to overcome them and what work remains to be done in the kernel as QUIC becomes more widely deployed.
