Online routing and spectrum assignment in flexgrid optical networks
2015 17th International Conference on Transparent Optical Networks (ICTON), 2015In this paper we propose a novel method for online routing and spectrum assignment (RSA) in flexgrid optical networks based on the theory of Markov Decision Processes (MDP). This theory has already been successfully applied to optimum state-dependent routing in multiservice circuit switched networks.

A Penalty-Based Routing and Spectrum Assignment in Fragmented Elastic Optical Network Spectrum
2021 National Conference on Communications (NCC), 2021Routing and spectrum assignment (RSA) has been an area of keen interest in Elastic Optical Networks (EONs). Improper resource provisioning causes fragmentation in the network spectrum, which leads to inefficient spectrum utilization. It also causes an increase in blocking of the new connection requests.

Routing modulation and spectrum assignment under spectrum conversion in elastic optical networks
2018 3rd International Conference on Microwave and Photonics (ICMAP), 2018The routing modulation and spectrum assignment (RMSA) constraints hinder the performance of elastic optical networks (EONs). To reduce this hindrance, various RMSA heuristics are proposed by utilizing spectrum conversion techniques in a novel way. The key to proposed conversion techniques lies in the selection of a conversion window (CW).

Reinforcement Learning applied to the Routing and Spectrum Assignment in Elastic Optical Networks
Latin American Conference on Computational Intelligence, 2022Elastic Optical Networks (EON) has emerged as technology in optical networks whose architecture can respond to the growing need for elasticity in allocating optical network resources. EON imposes physical layer constraints on traffics.

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 ...

Routing and spectrum allocation (RSA) is one of the key problems in EONs since bandwidth fragmentation generated by establishing the connection dynamically. In this work, we propose a routing and spectrum allocation algorithm based on Maximum Spectrum Completeness (MSC) which selected the completely contiguous frequency of the light-path and avoiding ...
