Dynamic optical switching architecture and its waveband traffic grooming algorithm in multi-granularity optical networks

Cross-connect ports for improved efficiency,linear programming were discussed.This paper uses a new type of multi-granularity optical switching structure and proposed a dynamic wave band grooming algorithm,Dynamic allocation of wavelength resources and select NSFNet topology simulation,the results show that the algorithm can not only reduce the number of multi-granularity cross-connect ports,but also can effectively reduce the blocking probability And improve network resource utilization.
