研究目的
To integrate Quantum Key Distribution (QKD) with Wavelength Division Multiplexing (WDM) networks without affecting the provisioning of classical service requests by proposing a wavelength fragmentation assignment scheme for QKD devices.
研究成果
The proposed WF-QKD-Tabu scheme effectively utilizes wavelength fragmentation to transmit quantum signals in WDM networks without affecting classical service requests, achieving satisfactory secure key rates with significantly reduced computational time compared to MILP-based approaches.
研究不足
The study focuses on static network scenarios and does not address dynamic network conditions. The performance of the proposed scheme is verified through simulations, which may not fully capture real-world network complexities.
1：Experimental Design and Method Selection:
The study proposes a wavelength fragmentation assignment scheme for QKD devices using Tabu search to maximize secure key rate.
2：Sample Selection and Data Sources:
Simulations are performed in a static network scenario with classical service requests' arrivals following the Poisson process.
3：List of Experimental Equipment and Materials:
The simulations for WF-QKD-MILP and WF-QKD-Tabu use ILOG CPLEX V
4：6 and Matlab respectively. Experimental Procedures and Operational Workflow:
The study involves conducting simulations to verify the performance of WF-QKD-Tabu and comparing it with WF-QKD based on MILP model (WF-QKD-MILP).
5：Data Analysis Methods:
The performance is evaluated in terms of relative secure key rates and blocking ratio of classical service requests.
