High‑Availability Design and Implementation of the BIGO Backbone Network
This article explains how BIGO’s backbone network achieves high availability through a three‑layer design—control‑plane HA using ETCD‑based Raft leader election, data‑plane HA with MPLS SR‑Policy and intermediate Route‑Reflection layers, and business‑level HA that combines traffic, optimization, and fault scheduling to ensure seamless service continuity.
