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
The present invention relates to optical transport network, more particularly, to the route switching method and device of a kind of optical ring network.
Background technology
At present, the structure of optical transport network is usually loop network (commonly referred to halo network), each section in looped network
Point can be base station or other network equipments, and by ring network structure the function that network is switched can be conveniently realized.Example
Such as, base station at breaks down in looped network, original transmission direction will be carried out according to the reverse direction of original transmission direction
Switch, so as to ensure the seriality of business.
But, in halo network, can not work if equipment fault or optical routing failure occurs in a base station, and
When failure is not repaired, occur another base station again and have a power failure, power failure, the stand-by power supply of base station not yet start the wink of work in base station
Between, the power failure base station will be caused to be adjacent the interruption of the optical routing between base station, so as to the moving back in clothes, business of halo network can be caused
Disconnected problem.The problem is illustrated with reference to Fig. 1.
Include 1 10G light device in the halo network shown in Fig. 1, this six base stations of A, B, C, D, E, F, 10G light devices and
Be linked in sequence successively composition looped network between this six base stations.When F stands to the optical routing between 10G light devices to interrupt, existing ring
Net protection system will avoid disrupted circuit automatically by the light path formula of falling debit, be reversed light path transmitting-receiving and keep in transmission not
It is disconnected, for example, the business of E base stations to 10G light devices, by by the transmission direction of original E base stations to F base stations to 10G light devices,
It is changed to behind E base stations to D base stations, C base stations, B base stations, A base stations and sends to 10G light devices.But in this case, if the ring of light
B stations have a power failure simultaneously in net, and the optical routing between B stations and A stations and C stations will interrupt, and so will result in C, D, E, F station because passing
It is defeated obstructed and move back clothes.
It is at present to repair the light path of F base stations to 10G light devices to this way to solve the problem, and sends attendant to remove B
Base station failure judgement reason, if the failure of B base stations cannot be repaired immediately, throws B base stations away, by the route of A base stations to B base stations
Directly connect to the route of C base stations with B base stations, also will B base stations exit from halo network, make A base stations and C base stations direct-connected.This
Sample, ensure that the business transmission of the base station of normal work in halo network.But, cause transmission obstructed the power failure of B base stations is solved
Problem during, due to needing attendant to go Solve on site problem, this just necessarily cause solve the problem efficiency it is low
Under, it is time-consuming longer, and then can also reduce affecting the indices of ring of light network operation.
From above-mentioned explanation, solve in prior art when the optical routing that there is a base station in halo network simultaneously cannot
The situation that work and another base station have a power failure, when may result in whole halo network and moving back the problem of clothes, the efficiency of solution is low,
Time-consuming, appreciable impact ring of light network operation.
