Technical Field

The embodiment of the invention relates to the field of optical communication, in particular to but not limited to an optical channel protection method, an optical channel protection device, optical channel protection equipment and a computer readable storage medium.

Background

In a conventional Optical Channel (OCH) service protection method of an Optical Transport Network (OTN), an Optical Protection (OP) board is configured at each source end or destination end of a service. At the service transmitting end, the transmitting end of the OCH service board is connected to the receiving end of the transmitting end OP board, the transmitting end OP board duplicates the optical signal into two parts, the optical signal is respectively transmitted from the transmitting end 1 and the transmitting end 2, and the two ports respectively transmit different Optical Multiplexing Section (OMS) service layers, that is, the source ends are double-transmitted. At the service destination, the two optical signals are respectively connected with the receiving port 1 and the receiving port 2 of the receiving port OP board, the receiving port OP board judges the current two optical signals, and sends the optical signals with higher quality to the OCH service board at the destination, that is, the destination receives preferentially. This is the traditional 1+1 protection of OCH. However, this method has the following disadvantages: firstly, the method can only select two paths of double-emitting optical signals, and if the two paths of signals can not meet the requirement of the host end service or the optical fibers of the OMS of the service layer where the two paths of services are located are broken, the service is interrupted at the moment; secondly, two OP boards need to be deployed for OCH 1+1 protection, and if the existing network has N OCH services, 2N OP boards are needed, for example, if the existing network has 1000 OCH services, 2000 OP boards need to be deployed, which is very costly.

The traditional 1: the N (N is greater than or equal to 1) method is to use 1 OCH to protect N OCHs, although the number of wavelengths can be saved compared with 1+1, only one OCH service can be protected currently, and if the protection channel is broken, the service is completely broken, so the reliability is very poor.

M: the N (M is less than or equal to N) method is also hardware-based, and M idle OCHs are needed to protect N actually running OCH services, where M OCHs need to be planned in advance, and a route of a service layer is fixed, so that there is also a problem that the running N services cannot be protected when M services are interrupted.

It is obvious that OCH service protection reliability in the related art is poor, and protection cost based on hardware OP board is high.
