summary

Bluebird implements network virtualization on Azure using P4 programmable ASICs and a control plane that pushes JSON goal states to a zonal multitenant service. Data-plane changes enlarge VXLAN VTEP space from 16k to 192k and add 32-bit VNIDs; a software-hardware route cache with DPDK SFE moves cold mappings to CPU, enabling a reported potential 5x mapping scale. Measured forwarding is full line-rate to 100 Gb/s, hardware forwarding <1 µs per ToR, software fall‑back ~9 µs, and only ~20–25% of routes are hot.
