Switching structure of network nodes In the switching structure shown in Figure 1, the impact of FDLs and TWC on switching performance is analyzed. In the figure, 1 to 4 represent the input and output of 4 optical fibers respectively. Each optical fiber multiplexes 9 wavelengths, one of which is used to send BCP, and the remaining 8 transmit burst data packets. The core switching module includes multiple space division cross matrix, TWC and FDLs. FDLs are configured at each input of the air division array, and TWC is configured at each output.
