Abstract
To improve the optical multicast packet switching node throughput performance, the new multicast scheduling algorithms are need urgently to overcome the entire optical multicast packet discard under the model of “one-shot”. A novel QoS difference optical multicast scheduling algorithm, which supporting the fan-out splitting for optical multicast packet switching node with limited range wavelength converter shared per node and without optical random access memory, is presented in the paper. By dropping partly not all the optical multicast packets which are replicated in the blocking multicast source, the proposed algorithm can improve output port utilization. Moreover, the algorithm is improved to provide service QoS difference for priority different traffic application. The simulation results show that the proposed algorithms remarkably improve the throughput of optical multicast packet switch node in comparison with the existing algorithms and support high priority service with high throughput QoS.
