Routing and Spectrum Assignment Algorithm Maximizes Spectrum Utilization in Optical Networks
37th European Conference and Exposition on Optical Communications, 2011This paper proposes a routing and spectrum assignment algorithm for elastic optical networks. The algorithm achieves high utilization of spectrum resources by considering the consecutiveness of common available spectrum slots among relevant fibers.

Routing and Spectrum Assignment in Elastic Filterless Optical Networks
IEEE/ACM Transactions on Networking, 2016Elastic optical networking is considered a promising candidate to improve the spectral efficiency of optical networks. One of the most important planning challenges of elastic optical networks is the NP-hard routing and spectrum assignment (RSA) problem.

We propose Mask RSA, an end-to-end deep reinforcement learning-based routing and spectrum assignment for elastic optical networks. Mask RSA masks unassignable choices, and decides routing and spectrum assignment concurrently for higher performance.

Routing and Spectrum Assignment in Spatial Channel Network-Based Inter-Datacenter Networks
2023 Asia Communications and Photonics Conference/2023 International Photonics and Optoelectronics Meetings (ACP/POEM), 2023We introduce spatial channel networks (SCNs) to the interconnection of data center networks (DCNs). We propose an integer linear programming (ILP) model to solve the routing and spectrum assignment problem for SCN-based inter-DCNs.

Algorithm for energy efficient routing, modulation and Spectrum Assignment
2015 IEEE International Conference on Communications (ICC), 2015Information and Communication Technology activities consumed 4% of the world energy in 2009, and such consumption will continue to increase due to the traffic growth of the Internet predicted for the next years. Techniques to make the core of the network more energy efficient has been proposed, among them, green routing has been considered a promising ...

On the Routing and Spectrum Assignment with Multiple Objectives
Advanced Photonics for Communications, 2014We study the routing and spectrum assignment problem with simultaneous minimizing of spectrum link and congestion level. We demonstrate that integrated objective approach could achieve better solutions than traditional ones based on single objective.
