We design a metric to measure the occupied holding time difference of frequency slots. With the metric, a routing and spectrum allocation algorithm in dynamic scenario is proposed to improve the network spectral utilization. Evaluation results show the proposed algorithm outperforms obviously in blocking probability.
Exploiting ‘Raman holes’ provides great Raman noise suppression in coexistence system comprised of classical and quantum channel. We suggest Return to Zero format for the classical communication and propose novel walk-off compensation technique to improve the method utilizing Raman holes.
This paper proposed a novel DWBA scheme for wavelength-agile based NG-EPON to cater frame resequencing problem and to improve fairness among ONUs while maintaining low packet delay for online scheduling upstream bandwidth on multiple wavelengths.
A resource allocation scheme consisting of joint assignment of routing, wavelength and time-slot is proposed to construct different channels in software-defined optical networks secured by quantum key distribution (QKD). Security level is considered by key-updating period.
An advanced dynamic spectrum allocation scheme based on fairness aware and fragmentation reduction is proposed to address the service fairness problem. Simulation results imply that the proposed scheme can greatly improve service fairness and reduce spectrum fragmentation.
We propose an inter-core crosstalk-aware routing, spectrum and core allocation scheme with spectrum bands and spatial Sp-Chs in multi-dimensional optical networks to get higher SE and lower XT. 15% reduction in XT is achieved.
