Abstract	Packet contention in photonic packet switches is a key issue in network performance. Without using a proper contention scheme, switches will get congested earlier. Although Optical Code Division Multiplexing, Wavelength Division Multiplexing (OCDM/WDM) applies a code and wavelength as a path in the node, the capacity granularity of OCDM/WDM may become too large to switch the packets among input and output. A possible solution for this issue is to employ optical buffering techniques that incorporate fiber delay lines (FDLs) in OCDM/WDM architecture. The proposed scheme takes the advantage of shared buffering, optical coding and wavelength conversion to enhance the switch performance. The performance evaluation of the hybrid optical switch architecture is validated through extensive simulation. This paper analyzes the performance of proposed system based on fixed sized packet (synchronized packet). It is shown that with this algorithm, the hybrid optical-buffered switch can achieve a throughput of ~ 0.99 and a loss rate of $1.9*10^{-3}$ respectively, at a heavy load of 0.9.
