Preventive Assignment of Regenerator in Translucent Optical Networks

In this paper we propose the APR algorithm to assignment regenerator (RA) in translucent optical networks. The aim of our propose to reduce the blocking probability cause by the degradation made by the establishment of a new light path in the others already established in the network. The APR is compared to other strategy that searches assign the minimal number of regenerator per light path (AMR). For the considered scenarios in this paper, the APR achieved a superior performance than AMR blocking probability terms.
