Since the spectrum fragmentation is an important issue for the dynamic demands allocation in the Elastic Optical Networks, minimization of it improves the spectrum utilization and decreases the blocking probability. In the paper, the dynamic deadline-driven multicast routing and spectrum assignment problem In the elastic Network is considered. Three spectrum fragmentation-aware algorithms were proposed and evaluated. Two of proposed algorithms use the well-known fragmentation metrics, while the third one utilizes a new original fragmentation increase estimator. The results of the experiments validating the quality of proposed methods and algorithms were reported and analyzed.
