【摘要】 Different multicasting schemes in optical packet switched networks are discussed,including the parallel mode,serial mode,and hybrid mode multicasting schemes.Simulated modeling technique is applied to compare the network-level performance of the three multicasting schemes.A conclusion can be drawn from the results that since the hybrid-mode multicasting scheme can increase the multicast success ratio and reduce the packet retransmission times compared with the other two schemes,it is the best choice for delivering multicasting sessions in the optical packet switched networks.
