Embodiment 1

[0025] The embodiment of the present invention first proposes a route switching method to perform route switching when the base station in the ring optical transmission network is powered off.

[0026] figure 2 shows the workflow of the route switching method applied to the ring optical transmission network provided by the embodiment of the present invention, the method includes:

[0027] Step 201, monitoring whether the main optical route and the backup optical route connected to the base station and its two adjacent base stations are working normally; and monitoring whether the output voltage of the base station power supply in the base station is less than a predetermined voltage threshold;

[0028] Specifically, the operation of monitoring whether the optical routing works normally is: monitoring whether the power of the optical signal sent and received by the base station is normal;

[0029] Specifically, the predetermined voltage threshold is greater than or equal to t...

Embodiment 2

[0074] The embodiment of the present invention also provides a processing solution for a base station to passively switch routes according to an instruction from a remote terminal.

[0075] Figure 6 It shows the working process of the route switching method applied to the ring optical transmission network provided by the embodiment of the present invention, as shown in Figure 6 As shown, the method includes:

[0076] Step 601, receiving a first switching instruction or a second switching instruction from a remote terminal, where the first switching instruction or the second switching instruction includes authority information;

[0077] Step 602, authenticating the authority information in the first switching instruction or the second switching instruction;

[0078] Step 603: In the case that the authority information in the first switching instruction passes the authentication, switch the two normal optical routes connected to the base station and its two neighboring base ...

Abstract

The invention discloses a ring optical transmission network route switching method and device. The method comprises that: under the situation that an output voltage of a power supply of a base station is less than the preset voltage threshold value through monitoring, the connection state of normally working two optical routes which are respectively connected with two adjacent base stations of the base station are switched into direction connection of the two optical routes according to the monitored normally working optical routes so that once power of the base station is about to be off through monitoring, the base station exits a ring optical transmission network and the two adjacent base stations of the base station are directly connected. The processing process can be automatically performed, and the processing process is rapid and effective with almost no influence on network operation so that problems in the prior art that the whole ring optical transmission network fails to work caused by the fact that one base station cannot work and another base station powers off at the same time in the ring optical transmission network can be avoided, and thus the problems that the solution scheme is low in efficiency and long in time consumption with substantial influence on the operation of the ring optical transmission network can be avoided.

Description

technical field [0001] The invention relates to an optical transmission network, in particular to a routing switching method and device for a ring optical transmission network. Background technique [0002] At present, the structure of the optical transmission network is usually a ring network (commonly called an optical ring network). Each node in the ring network can be a base station or other network equipment. The network switching function can be easily realized through the ring network structure. For example, if a base station fails in the ring network, the original transmission direction will be switched in the reverse direction of the original transmission direction, so as to ensure service continuity. [0003] However, in the optical ring network, if a base station fails to work due to equipment failure or optical routing failure, and another base station loses power when the failure is not repaired, at the moment when the base station loses power and the backup pow...
