In wavelength switched optical networks (WSON), quality of transmission (QoT) can be guaranteed by regenerating the optical signal in intermediate nodes. Regeneration can also offer wavelength conversion. When only few regenerators are placed in the WSON, the main issue is to optimally select the nodes where regeneration and wavelength conversion should take place. This paper proposes a distributed strategy for joint selection of wavelengths and regeneration locations (points) in a dynamic WSON with GMPLS control plane. To support the strategy, extensions to the RSVP-TE protocol are proposed. Simulation results show a significant improvement of the connection blocking and fairness, as well as a reduced amount of used regenerators in the network compared with existing strategies, which are based on disjoint and non-distributed resource selection
