Disaggregating the Network: Switching as a Service

on YouTube ↗37m

" summary

Facebook disaggregates switching hardware and software by building white‑box switches (Wedge, Backpack) that run FBOSS on a CentOS microserver attached to a Broadcom ASIC, enabling 100Gb top‑of‑rack and chassis designs and a TPM‑equipped board. Upgrades use Broadcom warm boot so fleet software rolls every two to four weeks with canaries; results show <1% transient and <0.1% permanent failures. Open Compute Project hardware, ASIC SDKs and tighter ops automation make rapid iterations possible.
