Capacity-Bound Evaluation and Routing and Spectrum Assignment for Elastic Optical Path Networks with Distance-Adaptive Modulation

Optical Fiber Communications Conference and Exhibition
A novel and effective network capacity estimation method and an RSA algorithm suitable for elastic optical path networks are presented. The proposed algorithm successfully achieves the utilization penalty of just 5-16% from the bound.

Multi-quality of service routing and spectrum assignment in elastic optical networks

2017 IEEE International Conference on Communications (ICC), 2017
In this paper, we investigate multi-quality of service (QoS) routing and spectrum assignment in elastic optical networks (EONs) by utilizing network state information in terms of bandwidth usage and holding time of established connections. Toward this aim, two types of traffic, namely big data traffic (BDT) requests, and fixed rate flow requests (FLRs)

Optimization Model and Algorithm for Routing and Spectrum Assignment in Elastic Optical Networks

2018 14th International Conference on Computational Intelligence and Security (CIS), 2018
In this paper, the problem of routing and spectrum assignment for static connection requests in elastic optical networks (EONs) is studied. Two different ratios of blocking formations are adopted, and a global constraint optimization model is established to minimize the ratio of blocking in the network.

Routing and Spectrum Assignment Algorithm with Fragmentation Minimization in Elastic Optical Networks

2014 Brazilian Symposium on Computer Networks and Distributed Systems, 2014
Elastic Optical Networks has drawn a lot of attention in the past few years because of its ability to transmit different data rates increasing or decreasing the optical spectrum according to the necessary demand, ensuring a high spectral efficiency. However, establishing and tearing down different connections ends up segmenting the spectrum in several ...

Routing modulation and spectrum assignment under spectrum conversion in elastic optical networks

2018 3rd International Conference on Microwave and Photonics (ICMAP), 2018
The 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).
