Cluster software defined optical networking controller (CSC) paradigm is exploited for multi-dimensional resource defragmentation (MDRD) in spatial division multiplexing enabled elastic optical networks. Experimental results show that spectral and spatial resources can be reorganized fast and effectively with cluster control technology.
Different multicasting schemes and their performance in the Optical Packet Switched networks are investigated in this paper. Computer simulation results show that compared with the parallel-mode and serial-mode multicasting schemes, hybrid-mode multicasting scheme is the best way to deliver multicast sessions in the OPS networks due to its highest performance.
