Flexible grid optical networks allow an efficient utilization of spectrum resources using 12.5-GHz frequency slot multiples instead of a fixed spacing, introducing however spectrum fragmentation (SF). In the literature, SF is often assumed to be a serious problem specifically in a dynamic traffic context. It is mostly related to the bandwidth blocking ratio(More)
Gridless Technology increases the spectral efficiency of optical fiber transmissions, introducing however spectrum fragmentation. In this work, we show that traffic forecast permits to avoid spectrum fragmentation, even with an uncertainty of 10% on the growth rate. Introduction Conventional fixed grid optical networks are characterized by an inefficient(More)
