The company presents the move as a shift from its in-house RUSH protocol toward an emerging IETF standard intended to support ingest, delivery, and playback across real-time media use cases.
The migration preserves the existing downstream pipeline: MoQ connections terminate at dedicated edge endpoints, where a translation layer converts MoQ frames to the RUSH format expected by backend systems. Meta says a configuration parameter selects MoQ or RUSH for a broadcast, enabling a reversible rollout. The company frames metric parity at Instagram Live scale as a prerequisite for exploring further deployments, including live playback.
