Zero-Configuration TURN Acceleration via eBPF Snooping

TURN servers suffer from excessive CPU overhead due to frequent kernel-to-userspace context switching, creating a critical bottleneck for WebRTC relay services. Most existing eBPF-based acceleration solutions require modifications to the TURN implementation itself, limiting widespread adoption. TURN-BPF introduces a protocol-aware snooping mechanism that offloads traffic without touching server code, making high-performance packet bypass practical for production deployments.
