As Moore's Law slows down, packet switch capabilities are falling behind datacenter demands. This has made optical circuit switches increasingly attractive in datacenter networks. These switches have already seen significant commercial use in the form of hybrid networks, which combine both packet switches and circuit switches. Recent advances in optical circuit switching technology can now operate fast enough to potentially fully replace packet switches, when combined with novel network designs.

This talk presents my research into Oblivious Reconfigurable Networks (ORNs), a design paradigm capable of using the full capabilities of emerging fast circuit switches. I will describe Shale, an ORN that achieves a tunable tradeoff between throughput and latency which is Pareto optimal for ORNs. Along the way, I will also touch on the current state of the art in commercially-deployed hybrid networks. Finally, I will discuss our present research into Semi-Oblivious Reconfigurable Networks (SORNs), which extend ORNs with intuitions found in commercial hybrid networks to further improve the performance possible on fast circuit-switched networks.
