Research On Optimization Design Of Establishing Optical Network

The generation and development of the fiber communication are a revolution on the history of telecommunication, particularly in recent years the increasing of data consumers and the broad-band demands have taken on increasing speed, this trend makes the Optical Networks the focus of the fiber communication field. The optimization of optical networks has become one of the most heated topics, both domestic and overseas, either in universities or research institutes. They have launched into a lot of manpower, material resources and enlist financial support to explore and research.Firstly, this thesis defines the concept, layering model, the developments, the traits, the application and present development about Optical Network. Secondly, the method of optimization design is expounded in great detail. An improved Ant colony Algorithm is put forword by contraposing the Travailing Salesman Problem (TSP). This Algorithm imports the MAX-MIN Pheromone and the Pheromone updating Mechanism of anificial ants, which avoids the defects of Prematurity stagnation. Thus improves the local and overall searching ability and enhances the quality of the solution.Simultaneously, this optimized algorithm is simulated on the network of twenty-five nodes. The result manifests better characteristics. Presently, the project designings are all based on the experiences of the designers and consumer's demand. This thesis layouts and simulates the shortest ring path for nine nodes to illuminate the network of the design. Then facility for establishing network from Huawei company is used to representing the optimized feasibility and validity of this Algorithm.Finally, the thesis is summarized and the tendency of the new technology is forecasted.
