Optical packets′ contention resolution in core node is a key to reali zing the all-optical multicast packet switching.A novel node architecture is proposed to resolve contention for optical multicast in thi s paper.In the proposed architecture,output shared network coding module and Fiber Delay Line Loop Shared Feedback Buffering (FDL-LSFB) module are designed in the node for contention resolution.As for the network coding module,XOR network coding is used as the first contention resolution method. All-optical logic XOR gates are used to encode conflicting multicasts and excha nge the carrier wavelength of the encoded multicast to avoid wavelength contention.The FDL-LSFB module,consisting of sub-switc hes and FDL buffer groups,is designed as the second contention resolution method.In FDL-LSFB module,FDL buffer groups are connected by sub-switches that guarantee the conflicting multicasts to enter or leave the FDL-LSFB module from any sub-swit ch.The FDL-LSFB module uses only a few FDLs and provides large buffering memories to resolve the multicast time contention w ith high FDL utilization.Moreover,the Minimum length Cascaded Buffer Scheduling Technique (MLCBST) is brought forward to sched ule the FDL-LSFB module.Based on the MLCBST,the total multicast scheduling strategy for optical multicast is designe d for the proposed node architecture.The simulation results show that the proposed node architecture and the scheduling strategy hav e an obvious effect in reducing packet loss probability (PLP) and decreasing the average delay.
