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.

Joint On-Demand Routing and Spectrum Assignment in Cognitive Radio Networks
2007 IEEE International Conference on Communications, 2007In cognitive radio networks, nodes can work on different frequency bands. Existing routing proposals help nodes select frequency bands without considering the effect of band switching and intra-band backoff. In this paper, We propose a joint interaction between on-demand routing and spectrum scheduling.

Symmetry-free routing and spectrum assignment: a universal algorithm based on first-fit
Journal of Optical Communications and NetworkingFirst-fit (FF) is a well-known and widely deployed algorithm for spectrum assignment (SA), but until our recent study [J. Opt. Commun. Netw.14, 165 (2022)], investigations of the algorithm had been experimental in nature and no formal properties of the ...

Crosstalk-aware Routing and Spectrum assignment in flexible grid networks
2016 IEEE Symposium on Computers and Communication (ISCC), 2016This work presents algorithms for the design phase of flexible grid optical networks considering the impact of in-band channel crosstalk. Due to crosstalk-induced interactions among different connections, malicious high-power signals can potentially spread widely in the network.

We explore the influence of topological features on a hybrid routing and spectrum assignment (HRSA) algorithm in elastic optical networks that prioritizes either routing or spectrum assignment for network source-destination node pairs.

Improved Routing and Spectrum Assignment formulations for optical OFDM networks
2016 8th International Symposium on Telecommunications (IST), 2016Efficient resource allocation in OFDM-based optical networks is directly affected by definition and formulations of Routing and Spectrum Assignment (RSA) problem. In this paper, we propose new Binary Linear Programming (BLP) formulations for the RSA problem that provide more efficient resource allocation in comparison with previous formulations. Unlike

Routing, Modulation and Spectrum Assignment using an AI based Algorithm
2019 11th International Conference on Communication Systems & Networks (COMSNETS), 2019There is a need of the networks which can accommodate the requirements of high data rate with low blocking probability. Optical networks are used most commonly as the backbone. They support high data rates, but need to be provisioned with low blocking probability. Due to the use of traditional Wavelength Division Multiplexing (WDM), optical network are
