WAVELENGTH REGENERATION IN A NETWORK

摘要

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.

1. A system for optimizing a telecommunications network having a plurality of gateway devices, a plurality of reconfigurable optical add-drop multiplexer (ROADM) devices, and a plurality of fiber segments interconnecting each of said ROADM devices to other of said ROADM devices or the gateway devices, the system comprising:
a processor; a display screen; a database storing costs associated with placement of regeneration devices in the network; and a graphical user interface rendered by the processor on the display screen, the graphical user interface being configured to display an optimal placement for at least one regeneration device in the network based on at least the costs stored in the database and forecasted traffic demand on the network.
