Routing, Modulation Format, Spatial Lane, and Spectrum Block Assignment in Static Spatial Channel Networks

Spatial channel networks (SCNs) and related key technologies have been proposed to increase the capacity flexibility of optical networks. We define network resource allocation problem in a static SCN as routing, modulation format (MF), spatial lane, spectrum block assignment (RMSSA) try solve it. In this paper, we derive relationship between traffic bit rate, transmission distance channels, MFs SCNs, obtain adoption method MFs. addition, introduce conversion nodes (CNs) into SCNs perform (MFC) for more efficient use resources. Moreover, RMSSA is modeled, heuristic lane minimization based on simulated annealing (LBMSA) algorithm problem. Simulation results show that when throughput small, LBMSA can carry requests with least amount resources maximize utilization. When high, inclined all rather than transmission. also utilization be improved by setting CNs MFC.
