METHOD FOR DETERMINING LOCATION AND GAIN SETTINGS OF AMPLIFIERS IN AN OPTICAL NETWORK BY USING A GENETIC ALGORITHM

摘要

A method for determining locations and gain settings of amplifiers in anoptical network isprovided. The method comprises evaluating allowable amplifier locations,randomly generatingsets of amplifier locations from the allowable amplifier locations, andapplying geneticoperations to the sets of amplifier locations until a predetermined exitcondition is satisfied. Thissystematic method is applicable to a variety of network topologies and takesinto accountexisting network limitations. In one embodiment, the method for determning thelocations andgain settings of the amplifiers uses the amount of operating margin in thenetwork to select setsof locations to be eliminated. In another embodiment, the method takes intoaccount anddetermines the placement of dispersion compensation modules (DCMs), choices ofwhich areprovided by DCM placement procedures.
