Abstract :
Traditional approaches to wavelength routing network design divide it into two separate problems: virtual topology design (VTD), in which best connections among nodes are derived from traffic demand; and routing-and-wavelength assignment (RWA) or physical topology design (PTD), in which physical paths are accommodated in the physical topology to support the requested connections. We presented an integer linear program for solving the PTD or routing and wavelength assignment problem in all optical networks with wavelength conversion. The approach is executed on a random mesh in Brazilian territory. The performance is studied for two traffic matrixes.
