Embodiment 1
[0028] As shown in Figure 1, the network layered model for the optical transmission communication network of the present invention comprises the following steps:
[0029] In the first step, the network is divided into the following four layers:
[0030] a, optical synchronous transport network (SDH) layer: this layer is used to describe the optical transmission communication network composed of equipment that meets SDH related standards, and this layer has basic attributes such as nodes, links, and services; the optical synchronous transport network ( The SDH layer is divided into client layer, SDH layer, and physical layer from top to bottom; the SDH layer is divided into channel layer and section layer from top to bottom.
[0031] b. Optical Transport Network (OTN) layer: This layer is used to describe the optical transmission communication network composed of equipment conforming to OTN-related standards. This layer has basic attributes such as nodes, links, and services; t...
Embodiment 2
[0041] As shown in Figure 2, in order to further describe the present invention in detail, an actual network is taken as an example here, and the goal of function realization is to plan and design the optical transmission communication network shown in Figure 2 using the method of the present invention. The implementation steps are as follows:
[0042] The first step is to divide the network into four layers according to the current situation and requirements of the network. in:
[0043] SDH layer: nodes are A, B, C; links are A-B, B-C, C-A; services are A-B.
[0044] OTN layer: Nodes are A, B, and C; links are A-B.
[0045] WDM layer: nodes have A, B, C; links have B-C.
[0046] PHY layer: Nodes are A, B, and C; links are A-B, B-C, and C-A.
[0047] The second step is to perform inter-layer mapping on the links of each layer of the network. The binding relationship is as follows:
[0048] SDH layer: Link A-B is bound to OTN layer service A-B, link B-C is bound to WDM lay...
