Embodiment

[0031] Example: such as figure 2 As shown, the power optical fiber backbone communication network contains N=6 nodes, and the routing path composed of multiple links between the paired nodes constitutes the service path carrying the electric power service, and the service realizes the transmission of service information through the links in the path.

[0032] In this embodiment, the number of network nodes in the power fiber optic backbone communication network is N=6, and the link fiber length information E between each pair of nodes i and node g ig (Unit: kilometer) As shown in Table 1, positive infinity means no link connection; link wavelength capacity C(i, g) and link carrying current between each pair of node i and node g in the power optical fiber backbone communication network Table 2 shows the number of wavelengths f(i, g) occupied by service links after some services.

Abstract

The invention relates to a spatial mapping power fiber backbone communication network service path planning method and system. The method comprises the steps of: acquiring power fiber backbone communication network link information; acquiring power fiber backbone communication network bearer service information; constructing a service path performance mapping space based on the relay node degree and the link resource occupation degree; selecting a new service path according to the second closest criterion of the spatial mapping distance; and configuring the new service path to update a bearerservice set until all the new service paths are completely planned. The spatial mapping power fiber backbone communication network service path planning method and system achieve the spatial mapping power fiber backbone communication network service path planning so as to effectively improve the usage balance of the power fiber backbone communication network resource.

Description

technical field [0001] The invention relates to the technical field of power fiber optic backbone communication, in particular to a method and system for planning a service path of a power fiber backbone communication network with spatial mapping. Background technique [0002] With the continuous construction of the smart grid and the rise of the energy Internet, the scale of the power optical fiber backbone communication network continues to expand, the grid structure becomes more and more complex, the structure becomes more and more complex, the business types become more diverse, and the transmission quality requirements become increasingly precise. The role has changed to a new type of power exchange system node integrating power collection, power transmission, power storage, power distribution and user interaction, which brings new challenges to the planning of power fiber optic communication networks. [0003] The business path planning of the power optical fiber backb...
