Analysis of Live Streaming Latency Causes and Optimization Strategies
The article examines why live‑streaming latency—averaging about five seconds on the studied platform versus three seconds on top e‑commerce services—remains high, pinpointing encoder, transcoding, CDN GOP‑cache, and player buffering as key contributors, and proposes optimizations such as shrinking GOP size, minimizing CDN cache tiers, tightening player buffers, and adopting ultra‑low‑latency protocols like RTS, RTM, or QUIC to achieve sub‑second delays.
