Abstract
An optical network including a plurality of gateway nodes interconnected with a plurality of intermediate nodes with segments of fiber. The network includes a plurality of devices, such as reconfigurable optical add drop multiplexers, optimally placed at various nodes throughout the network. The device placement is optimized with an integer linear programming analysis considering span definition such that any given span involves some number of segments not exceeding a number of segments that would require wavelength regeneration, cost of placement of a device at a given node, cost of wavelength regeneration, and various parameters and constraints.

5. A system for optimizing a telecommunications network, the system comprising:
-
at least one processor; and memory, operatively connected to the at least one processor and containing instructions that, when executed by the at least one processor, cause the system to; access information describing fiber segments in the telecommunications network; identify, based on the information, a plurality of spans of the fiber segments in the telecommunications network that can be traversed by a wave without intermediate regeneration; generate an optimal placement for at least one regeneration device in the telecommunications network based on at least; a constraint requiring that, for at least a particular span of the identified spans, the particular span does not exceed a maximum number of intermediate nodes that are interconnected without intermediate regeneration; and cause display of the optimal placement for the at least one regeneration device in a graphical user interface. - View Dependent Claims (6, 7, 8, 9, 10, 11)
