# On Wavelength Assignment in WDM Optical Networks

Chapter

## Abstract

Routing and wavelength assignments are fundamental problems in efficient use of optical networks that employ wavelength division multiplexing of the fiber bandwidth. Three perspectives are taken in this chapter. First, the computational complexity of wavelength assignment is considered. Next, wavelength assignment with traffic restricted to all-to-all gossiping is examined, where lower bounds and an approximation algorithm are developed. Finally, results on the related problem of file transfer scheduling in optical networks are given for several network topologies.
