Abstract

WDM/TDM star-coupler architectures have been proposed for building high-radix optical switches to enhance data centre network scalability. Here we propose a 1000-server star coupler network, which uses parallel OCS sub-stars to scale the network capacity to 256 Tbps. The harmony of distributed ns-timescale hardware schedulers and parallel OCS resource management achieves a throughput of 82.5% (200 Tbps) while incurring an average latency of 9.6 µs at 100% network load.
