Spectral and spatial 2D fragmentation-aware routing and spectrum assignment algorithms in elastic optical networks [invited]

TL;DR: Simulation results indicate that the proposed fragmentation-aware (FA) RSA algorithm and the FA algorithm with congestion avoidance (CA) outperform the existing schemes in terms of blocking probability (BP) reduction.
Journal ArticleDOI

Dynamic and Adaptive Bandwidth Defragmentation in Spectrum-Sliced Elastic Optical Networks With Time-Varying Traffic

TL;DR: This paper investigates dynamic and adaptive bandwidth defragmentation in EONs with time-varying traffic using connection reconfigurations and proposes intelligent timing selection and adaptive DF ratio selection methods to tackle the tradeoff between the bandwidth blocking probability (BBP) performance and operational complexity.
Journal ArticleDOI

On the Effect of Bandwidth Fragmentation on Blocking Probability in Elastic Optical Networks

TL;DR: The theoretical analysis indicates that two factors related to bandwidth fragmentation have effects on the blocking probability: the extent that the available slot-blocks on different links are aligned on spectrum locations, and the sizes of the availableslot-blocks in links' spectra for future requests.
Proceedings ArticleDOI

Fragmentation-aware routing, modulation and spectrum assignment algorithms in elastic optical networks

TL;DR: This work investigates the principle of how dynamic service provisioning fragments the spectral resources on links along a path, and proposes corresponding RMSA algorithms to alleviate spectrum fragmentation in dynamic network environments.
Proceedings ArticleDOI

Bandwidth defragmentation in dynamic elastic optical networks with minimum traffic disruptions

TL;DR: Simulation results indicate that in order to make the bandwidth blocking probability (BBP) comparable with that from the Greenfield scenario, the proposed algorithm only needs to reroute ~30% existing connections.
