A multiwavelength packet switched network and node structure model based on dense wavelength division multiplexing is proposed in the unidirectional network topology. Based on this, a simplified cached fixed routing algorithm is proposed to simulate the network in steady state Loss rate and throughput of normalized nodes.The simulation results show that the application of Dense Wavelength Division Multiplexing (DWDM) technology can dramatically reduce the number of packet-switched network caches and greatly improve the overall performance.
