Abstract

This paper proposes a new spectrum assignment algorithm in elastic optical networks. The goal of the proposed algorithm is to allocate spectrum bands that cause less interference to the quality of transmission of the other circuits. A performance evaluation study was carried out comparing the proposed algorithm with eight other spectrum assignment algorithms presented in the literature. Results of the performance evaluation study show that the proposed algorithm presented a superior performance to the other algorithms in terms of circuit blocking probability and bandwidth blocking probability for the scenarios evaluated. In general, the proposed algorithm presented a minimum gain of 28.92% in terms of circuit blocking probability and a minimum gain of 3.63% in terms of bandwidth blocking probability.
