Abstract

A distributed network including at least two Reconfigurable Optical Add/Drop Multiplexers (ROADMs) may be designed by a method including simulating routing of data traffic in a distributed network. The method may also include identifying a first location for placement of a first ROADM based at least partially on the simulated routing of the data traffic. The method may also include simulating rerouting of data traffic in the distributed network including the first ROADM at the first location. The method may further include identifying a second location for placement of a second ROADM based at least partially on the simulated rerouting of the data traffic.
