Joint Fragmentation- and QoT-Aware RBMSA in Dynamic Multi-Band Elastic Optical Networks
Paper in proceeding, 2024

Efficient utilization of fiber bandwidth is essential for reducing the total cost of ownership
associated with deploying new fiber plants. One of the challenges in dynamic multi-band elastic optical networks
(DMB-EONs) is spectrum fragmentation. It stems from the wavelength continuity constraint, the dynamic arrival
and departure of service requests, and variations in quality of transmission (QoT) across the wavelength division
multiplexing (WDM) channels. This study introduces a QoT-aware algorithm for routing, band, modulation
format and spectrum assignment (RBMSA) that considers the spectrum fragmentation along each channel to
reduce service blocking ratio (SBR) in DMB-EONs. Simulation results indicate that the proposed algorithm
reduces SBR by up to 33.2% compared to a reference RBMSA algorithm that considers only QoT at the cost
of increasing the average path length by 4.4%

quality of transmission.
