Paper Abstract

We proposed a dynamic routing and frequency slots allocation scheme which adopted the adaptive modulation for a novel Spectrum-sLICed Elastic optical path network (SLICE). In our dynamic routing scheme, both spectrum resource availability (SRA) and distance (hop number) are considered at the modulation format selection phase for adaptive modulation. We then conducted numerical simulation to compare our Spectrum Resource Adaptive and Distance Adaptive (SRA-DA) mechanism with previous DA in both small network topology and 7×7 mesh topology. Results shown that SRA-DA mechanism achieved lower blocking rate and higher slots utilization compared to DA in bigger networks.
