Algorithmes de routage dynamique dans les reseaux optiques (French text).

摘要

During last years, many applications multi-media required a high-speed rate of data transfer and a high reliability of the transmission channels. In this situation, the optical networks based on WDM technology represent by their great bandwidth an interesting alternative to the current communication networks. The management of these networks involved several problems among which the dynamic routing.; The purpose of this thesis is primarily the development of new dynamic routing algorithms to improve the performances obtained by former algorithms in this field. To achieve our goals, we started with a mathematical formulation of the problem above exposed. Then we proposed a new approach to estimate the congestion on a path as well as an additional criterion to analyze the links on a path. We then deduced two new dynamic routing algorithms. We thus defined a total architecture of the optical networks, which allowed us to implement the algorithms proposed. The performance analysis of our two algorithms enabled us to compare them with existing algorithms. (Abstract shortened by UMI.)
