Deploying User-space TCP at Cloud Scale with LUNA

Explore a conference talk from USENIX ATC '23 that delves into the deployment of LUNA, a user-space TCP stack, at cloud scale within Alibaba Group. Learn about the challenges faced by kernel-based TCP stacks in meeting modern performance demands and discover how LUNA addresses these issues. Examine the design tradeoffs and unique features of LUNA, including its thread, memory, and traffic models. Gain insights from the lessons and experiences gathered during field deployment. Analyze microbenchmark evaluations and production system performance statistics that demonstrate LUNA's superiority over kernel and other user-space solutions, showcasing up to 3.5x improvement in throughput and up to 53% reduction in latency.
