Embodiment 1
[0024] Embodiment one: as attached figure 1 An optical path planning method is shown, which is used to plan and select an appropriate path between certain two nodes in an optical fiber communication network composed of several optical cables and nodes on them.
[0025] The method specifically includes the following steps:
[0026] 1. Determine the starting and ending points:
[0027] Determine the starting point and the ending point of the path to be planned in the optical fiber communication network.
[0028] 2. Flood layer by layer and identify the cost value:
[0029] First define the end point as layer 0 node A 0 , its cost value is 0, and then the node A at layer 0 0 Flood outward, looking for node A with layer 0 0 directly adjacent nodes and defined as layer 1 node A 1 . At each layer 1 node A 1 mark the cost value of the optical path formed by the optical cable between it and the terminal. The cost value is based on the node A 1 The parameters of the optical c...
