Live video just got more live: Introducing Concurrent Streaming Acceleration

Concurrent Streaming Acceleration is a new technique introduced by Cloudflare to reduce end-to-end latency of live video on the web. The technique involves splitting up video segments into smaller chunks, enabling client players to start playing the chunks while they're still being created or downloaded. This approach can significantly decrease live streaming latency from 20-30 seconds to around 5-10 seconds. CDNs play a crucial role in delivering low-latency live video at scale, and Cloudflare's solution removes the cache lock, allowing multiple clients to safely read from a single file while it's still being written. This feature has been rolled out and can potentially shave precious seconds off end-to-end latency for live video delivery.
