  We propose Kevin, a novel demand-aware reconfigurable rack-to-rack datacenter
network realized with a simple and efficient control plane. In particular,
Kevin makes effective use of the network capacity by supporting integrated and
multi-hop routing as well as work-conserving scheduling. To this end, Kevin
relies on local greedy routing with small forwarding tables which require local
updates only during topological reconfigurations, making this approach ideal
for dynamic networks. Specifically, Kevin is based on a de Bruijn topology
(using a small number of optical circuit switches) in which static links are
enhanced with opportunistic links.
