Q&A Session 1 – Luca Niccolini
summary
Cloud operators describe a predictable network built by co-designing software and hardware: a uniform single-chip whitebox platform running a common control plane via a switch abstraction (PSI/SAI), verified with open-source hardware/software tests and vendor runs. Upgrades use canary devices with repeated upgrade/downgrade loops and monitoring; SDN orchestration enforces a 5–10% capacity cap per reconfiguration step and data-plane backstops. Wide-area routing standardizes on SRv6 and BGP, and fboss SDK gating uses fboss tests on GitHub for vendor qualification.
