Physical Network Design at Scale

" summary

Meta describes Loom, an end-to-end system that automates physical network design: Planogram places every network device to a precise rack and row using an ILP + reinforcement learning decomposition and lexicographic objectives, then a fiber module materializes connectivity into trunk, breakout and shuffle cables. Results: deployed across 4 regions, 20+ buildings and 100 concurrent design variants, initial device+fiber allocation drops from months to days, validation drops to minutes, and the system outputs installation instructions and millions of strands modeled and BOMs.
