Abstract

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.
