Watch Meta’s engineers discuss optimizing large-scale networks

This post details Meta's engineers discussing optimizations for large-scale networks across three themes: data center networking (FBOSS, SAI, in-house switches), WAN optimizations (global optical network, submarine fiber optics like Bifrost, Echo, 2Africa), and operational efficiency (Millisampler for fine-grained traffic analysis, Network SLOs for QoE correlation, and Shiv for L4 routing consistency).
