Abstract

Traffic grooming in WDM optical networks is one of the most important and hot problem in the area of optical networks. We first systematically investigated the grooming problems in WDM optical tree networks with traffic requirements in this thesis. We first propose the genetic algorithms (GA) to deal with a variety of grooming problems in tree networks, and propose the connection model of optical tree networks, and apply the technology of wavelengths-reuse in the decoding of the individual in the genetic algorithms, and get good grooming results.
