QPS-ToR: A Parallel Iterative Switching Algorithm for Reconfigurable Optical Datacenter Switching
QPS-ToR is proposed, which replaces NegotiaToR's scheduling logic with SW-QPS, a sliding-window algorithm originally proposed for crossbar scheduling that achieves around 90% throughput with a single low-complexity iteration.
