Gilberto Bertin discusses the architecture of Cloudflare’s automatic DDoS mitigation pipeline, the initial packet filtering solution based on Iptables, and why Cloudflare had to introduce userspace offload. Bertin also describes how they switched from a proprietary offload technology to XDP for network stack bypass and how they are using XDP to load balance traffic.


Gilberto Bertin works as a System Engineer at Cloudflare London. After working on variety of technologies like P2P VPNs and userspace TCP/IP stacks, he joined the Cloudflare DDoS team in London to help filter all the bad internet traffic.
