Scaling PULSE Data Center Network Architecture and Scheduling Optical Circuits in Sub-Microseconds

PULSE, an optical circuit switched data center network, employs custom ASIC schedulers to reconfigure circuits in 240 ns. The revised PULSE architecture scales to 10,000s blades, achieves >95% sustained throughput, with low median (1.23 μs) and tail (145 μs) latencies, while consuming 115 pJ/bit and costing $9.04/Gbps.
