Abstract

The invention discloses a service protection method of an optical fiber link in air-ground integrated optical network and a controller, and the method comprises the steps: respectively selecting two accessible ground stations S'and D 'for a head optical node S and a tail optical node D of a to-be-protected optical fiber link; constructing a spatial optical connection route P (S '-> D') from S 'toD'; configuring each satellite through which S, D, S ', D' and P (S '-D') pass, and constructing an S-S '-P (S'-D ')-D'-D link protection structure; and when the S-to-D optical fiber link fails, the optical nodes S and D continue to transmit the service data by using the link protection structure. According to the invention, the service protection problem of the ground optical fiber link in a disaster scene can be solved.

Description

technical field [0001] The invention relates to the technical field of air-ground integrated optical network, in particular to a service protection method and controller for optical fiber links in an air-ground integrated optical network. Background technique [0002] Frequent natural disasters and man-made damage have seriously affected the normal operation of optical networks. For each optical fiber link of the terrestrial optical network, when a fault occurs, the existing survivability technology can be used to protect and restore the interrupted service. However, most existing survivability technologies often rely on the connectivity of the terrestrial optical network itself for implementation. When natural disasters or man-made damage cause large-scale failures in the nodes or links of the terrestrial optical network, the network is isolated and even paralyzed. At this time, only relying on the terrestrial optical network itself cannot realize the recovery of interrupt...
