A cost-effective and extensible testbed for transport protocol development

Cloudflare is developing the QUIC protocol, a secure and multiplexed transport protocol that aims to perform better than TCP under certain network conditions. The company has built a testing lab focused on protocol analysis only, consisting of dedicated x86 hosts. The lab helps with multiple transport protocol development, debugging, performance comparison between each protocol, finding bottlenecks or errors easily, and more. It also includes test automation and visualization tools for data processing and analysis. Additionally, Cloudflare is testing the new transport protocol on mobile devices to understand real-world performance issues better.
