Abstract :
Currently, service characteristic is rarely considered in service processing for the optical network. In this paper, we introduce a novel service-basedscheme which will buffer and schedule services to optimize the blocking performance of flexi-grid optical network based on Software Defined Network (SDN). This scheme gives sufficient consideration to the diversity of services in SDN network. Besides, new algorithms of service scheduling and adjustment are proposed to improve the network performance. Numerical simulation results demonstrate a lower blocking probability and verify the superiority to the conventional scheme.
