Abstract
System for minimizing the cost of an optical network. A method is provided for designing an optical network to have minimized costs. The optical network has a plurality of nodes connected by interconnecting optical fibers. The method comprises inputting channel parameters associated with the optical network, inputting cost parameters associated with the optical network, calculating band parameters associated with the optical network, restricting at least one parameter associated with the optical network to having only integer values, and using an integer linear program to solve a minimization objective function that allows the cost of the optical network to be minimized, wherein the minimization objective function includes selected channel, cost and band parameters.
