Investigation of optical buffer capacity using large-scale fiber delay lines for variable-length optical packet switching

We investigate an actual capacity of optical buffer using fiber delay lines (FDLs) and a prioritized buffer management for variable-length optical packets. From tests of Nx1 packet contention, we confirm the 31-FDLs buffer can resolve the contentions while keeping packet loss less than 10-3 until a total packet rate of inputs reaches about 60%.
