Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings, but the scope of the present invention is not limited in any way.
[0024] 1. Simplified structural block diagram
[0025] The invention proposes a simplified structural block diagram of using parallel communication optical fibers to solve the competition of burst data packets in optical burst switching. As shown in Figure 2, the parallel optical fiber link in the figure is composed of two communication optical fibers of the same attribute plus joints connected to nodes at both ends of the optical fibers. The joints are composed of optical wavelength division multiplexers / demultiplexers, high-speed optical Fiber delay lines (FDLs) etc. The wavelength division multiplexing (WDM) link connecting OBS node i and node i+1 is composed of two parallel optical fibers with the same attribute, that is, parallel optical fiber 0 and parallel optical fiber 1 in FIG. 2 . The optic...
