A Centralized Wavelength Resource Allocation Algorithm in SDON

摘要

Based on the research and analysis of the software defined optical networks (SDON) resource allocation mechanism, this paper proposes a new wavelength resource allocation algorithm, key link capacity-based algorithm (KLCAB). This algorithm more accurately describes the wavelength resource allocation impact, and simulation results shows KLCAB can keep lower blocking rate, which proves it improves whole network resource utilization.
