Abstract: The present disclosure presents a system and method for determining a logical topology of a network, given the network's physical topology. More particularly, a logical topology is implemented across a plurality of optical circuit switches that interconnect the nodes of a network. Each of the optical circuit switches includes an initial internal configuration. The internal configuration of the optical circuit switches are swapped to generate new logical topologies. A fitness is determined for each of the generated topologies. The fitnesses of the topologies are then ranked and the most fit logical topology is implemented in the network.

Abstract: Systems and methods of configuring a datacenter network are provided. A datacenter network can have a first stage of switches and a second stage of switches. A first stage of switches each including at least one first stage switch can be defined. A second stage of switches each including at least one second stage switch can be defined. For each first stage switch group of a first set of first stage switches, a communication link can be assigned between each first stage switch and each second stage switch in a respective second stage switch group. For each first stage switch group of a second set of first stage switches, a communication link can be assigned between each first stage switch and a single second stage switch of each second stage switch group.
