Flexible Bandwidth Allocation in Filterless Optical Networks
2015 (English)In: IEEE Communications Letters, ISSN 1089-7798, Vol. 19, no 4, 565-568 p.Article in journal (Refereed) Published
We introduce the new concept of an elastic filterless optical network and propose an efficient heuristic algorithm for solving the static routing and spectrum assignment problem. Our simulation results obtained for different network topologies under multi-period traffic show increasing bandwidth savings with the growth of traffic load compared to a fixed-grid scenario. We also show the benefits of periodical spectrum defragmentation.
