This thesis mainly focuses on all-optical lightpaths establishment. We consider all along the thesis optical networks with finite resources, that is with a given maximum amount of wavelengths per fiber. Both exact and approximate optimization techniques are considered. In a first step, we investigate the problem of routing and wavelength assignment (RWA) considering permanent lightpath demands (PLDs) and develop ILPs (Integer Linear Programs) for both the routing and the wavelength assignment sub-problems. This work is then extend to deal with two classes of traffic demands referred to as scheduled lightpath demands (SLDs) and random lightpath demands (RLDs). On one hand, SLDs are characterized by pre-known dates of arrival and life duratio...
