Rush claims a simpler live stack: one subscription HTTP request using HTTP push from CDN, a custom container with 36-byte metadata records per frame that enables per-frame addressing and lossy playback, and server-side ABR at the edge using socket-level signals and HTTP/3 extensions for delivery-timeouts. Startup drops from ~five RTTs to one, ABR switches without client requests, per-frame latency control and WebRTC-like retransmit behavior are implemented, and the system already runs in production at scale for millions of viewers.
