Abstract

We propose an OCS data center network and control system that uses distributed hardware schedulers to reconfigure circuits every 40ns. The network is scale-resilient to 8192 servers, achieving >92% sustained throughput, with low median (120ns) and tail (6.6 microsecond) latencies, while consuming 415 pJ/bit.
