Delivering Reliable Live Streaming Over Unreliable Backbone Networks
summary
Meta implements a redundancy-first ingest path that translates RTMPs to Rush in POPs, writes video as configurable HTTP chunks to distributed storage OIL, and performs dual parallel writes to two data centers while readers accept the first arrival. The system effectively implements SMPTE 2022‑7 at the application layer, reduces streams impacted by backbone events by over 40%, and increases time between viewer rebuffers by about 6%, demonstrating clear operational improvement.
