Routing, Modulation and Spectrum Allocation in Elastic Optical Networks
2018 26th Telecommunications Forum (TELFOR), 2018Elastic optical networks are seen as an efficient solution for future optical networks. In these networks, the routing, modulation and spectrum allocation problem consists of finding an optimal network utilization by jointly addressing all three aspects.

Spectrum allocation in spectrum-sliced elastic optical path networks using traffic prediction
Photonic Network Communications, 2015Spectrum-sliced elastic optical path (SLICE) networks distribute data on a number of sub-carriers overlapped in frequency domain to provide efficient sub-wavelength and super-wavelength traffic accommodation. In SLICE networks, a routing and spectrum allocation algorithm assigns a spectrum path (SP) to any demand with just enough contiguous sub ...

Adaptive spectrum allocation algorithm for elastic optical networks with multicasting
Journal of High Speed Networks, 2018The rapid change in traffic behavior and the tremendous growth in bandwidth demand have promoted the development of a new generation of optical networks known as elastic optical networks (EONs). EONs provide scalable, flexible, and efficient assignment of network resources. Spectrum allocation is one of the most important factors in the success of EONs.

2015 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT), 2015
The recently proposed spectrum sliced elastic optical path network (SLICE) is expected to substantially increase network resource utilization efficiency. In order to meet this high expectation it is necessary to provide an efficient solution to the NP-complete routing, modulation and spectrum assignment (RMSA) problem.

A tabu search algorithm for routing and spectrum allocation in elastic optical networks
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014In this paper we present a tabu search-based algorithm, which is dedicated to solving the routing and spectrum allocation problem in elastic optical networks. To evaluate performance of the proposed method, we carry a number of experiments on realistic network topologies.

Relative Cost Routing, Modulation and Spectrum Allocation in Elastic Optical Networks
2021 International Conference on Information Networking (ICOIN), 2021This work extends the adaptive RSA algorithm that is based on the relative cost for solving the routing, modulation level and spectrum assignment (RMSA) for elastic optical network (EON). In planning and execution of EONs, RMSA is a viral aspect.

Tidal-Traffic-Aware Routing and Spectrum Allocation in Elastic Optical Networks
Journal of Optical Communications and Networking, 2018With the growing popularity of 5G mobile communications, cloud and fog computing, 4K video streaming, etc., population distribution and migration have increasing influence on traffic distribution in metro elastic optical networks (EONs). Traffic distribution is further diversified according to people's tendency to use network services in different ...

A Clique Partitioning Based Spectrum Allocation Strategy in Elastic Optical Networks
2019 21st International Conference on Transparent Optical Networks (ICTON), 2019In this paper, a clique partitioning based spectrum allocation approach is proposed to reduce spectrum fragmentation by partitioning the entire spectrum into separate spectrum blocks and assigning spectrum using different spectrum assignment policies.
