OpenOptics provides a concrete software stack and testbed that decouples optical hardware from control: a time-flow table abstraction plus a re‑architected per‑port time‑bucket queueing backend that schedules packets to future time slices. The team builds a programmable‑switch testbed, implements six architectures and seven routing schemes, and demonstrates a record 2 µs minimum optical circuit on commodity devices; evaluations include a 108‑ToR benchmark suite, TCP experiments showing severe reordering for spray routing, and full open‑source code.
