For example, the linkage interface may be RPC, HTTP, webservice, restful, etc., and the type of linkage interface is not limited in the embodiments of the present application. Based on the linkage interface, the embodiment of the application can realize the automatic switching flow after the optical fiber link fails.
In one embodiment, the at least two fiber links include one primary fiber link and at least one backup fiber link;

Specifically, at least two optical fiber links exist between the optical splitting device managed by the splitter network manager and the back-end device managed by the application system network manager, and the at least two optical fiber links comprise a main optical fiber link and at least one standby optical fiber link. By way of example, one of the at least two optical fiber links may be designated as a primary link (primary optical fiber link) and the remaining links as backup links (backup optical fiber links).
The link abnormality alarm is used for representing that the main optical fiber link is abnormal in light receiving, and when the main optical fiber link is in fault, the back-end equipment can generate the phenomenon of abnormal light receiving, so as to alarm the network management of the application system. Optionally, the normal link is a spare optical fiber link, and the embodiment of the application can realize full-automatic switching of the intelligent optical power splitter fault link, and can automatically switch to the spare link when the link is ensured to be faulty.
In one embodiment, the switching command carries a port identifier corresponding to the primary optical fiber link and a port identifier corresponding to the standby optical fiber link;
the switching command is used for indicating the optical splitting equipment to close the port corresponding to the main optical fiber link and open the port corresponding to the standby optical fiber link.
Specifically, the splitter network manager automatically issues a switching command after receiving a link switching request, where the switching command may carry a port identifier corresponding to the primary optical fiber link and a port identifier corresponding to the standby optical fiber link, and further, the splitter device may open a certain port and/or close a certain port according to the switching command, so as to implement link switching.
The fault link switching method can realize full-automatic switching of the fault link of the intelligent optical power splitter, optimize switching time delay from minute level to millisecond level, and improve switching efficiency and reliability of an important data link acquisition system.
In one embodiment, as shown in fig. 3, a method for switching a failed link is provided, and the method is applied to the splitter network management in fig. 1 for illustration, and includes the following steps:
step 302, a switching command is output in response to receiving a link switching request transmitted by an application system network manager; the link switching request is obtained by processing a link abnormality alarm transmitted by the back-end equipment through an application system network manager;
the switching command is used for indicating the light splitting equipment to switch from a fault link corresponding to the link abnormality alarm in the at least two optical fiber links to a normal link in the at least two optical fiber links.
Specifically, when the splitter network manager receives a link switching request transmitted by the application system network manager, a switching command is issued to the optical splitting device in response to the link switching request, and the optical splitting device can switch from a fault link corresponding to a link abnormality alarm in at least two optical fiber links to a normal link in at least two optical fiber links.

Optionally, the splitter network manager may receive a link switching request transmitted by the application system network manager through a linkage interface, where the linkage interface may include at least one of a remote procedure call protocol RPC interface, a hypertext transfer protocol HTTP interface, a webservice interface, and a performance layer transition interface.
The embodiment of the application adds a linkage interface between the network manager of the splitter and the network manager of the application system. If the back-end application system detects that the link receives light abnormally, the back-end application system network manager informs the splitter of the link abnormality of the splitter network manager through the linkage interface, and then the splitter network manager issues a command to switch to a normal link (such as a standby link), so that the switching time delay is optimized from a minute level to a millisecond level, and the full-automatic switching of the fault link of the optical power splitter is realized.
In one embodiment, the method further comprises:

The light emission intensity signal may refer to light emission power, and the light emission threshold may be a set value, which is not limited in the embodiment of the present application.
Taking the optical splitter as an optical power splitter for example, the splitter network manager can also switch when detecting that the light emitting power of the main interface of the optical power splitter is too low (for example, lower than a set value). The main interface may refer to a port of the main optical fiber link at the optical power splitter side; in the embodiment of the application, the network manager of the splitter can acquire the light emitting condition of the port of the light splitting equipment side and the light receiving condition of the back-end equipment side, so that the normal link can be automatically switched when the link fails, further the full-automatic switching of the failure link of the back-end equipment is realized, the switching time delay is optimized from the minute level to the millisecond level, and the switching efficiency and the reliability of an important data link acquisition system are improved.

Specifically, at least two optical fiber links exist between the optical splitting device managed by the splitter network manager and the back-end device managed by the application system network manager, wherein one optical link of the at least two optical fiber links can be designated as a main link (a main optical fiber link), and the other links are designated as standby links (standby optical fiber links).
For example, the splitter network manager may set a disaster recovery backup port group for the optical splitter device, where a certain optical fiber link in the port group is designated as a primary optical fiber link, and the remaining links are designated as backup optical fiber links. Optionally, taking the optical splitting device as an optical power splitter as an example, a disaster recovery backup port group can be set for the optical power splitter, a certain optical link in the port group is designated as a main link, and the rest links are designated as backup links.
Further, the network manager of the splitter can determine disaster recovery backup port group information of each output port of the splitter; the disaster recovery backup port group information is used for indicating the primary optical fiber link and the backup optical fiber link. The disaster recovery backup port group information may include port identifiers of output ports corresponding to the primary optical fiber links, and port identifiers of output ports corresponding to the backup optical fiber links one by one, respectively.

The embodiment of the present application is not limited thereto.
In one embodiment, the back-end device is configured to monitor a received light intensity signal of the port, and send out a link abnormality alarm according to the received light intensity signal and a received light threshold.
Specifically, when a link fails, the back-end device generates a light receiving abnormity phenomenon, and the back-end device alarms to an application system network manager. The back-end equipment can monitor the received light intensity signal of the port so as to send out a link abnormality alarm according to the received light intensity signal and the received light threshold value.

Taking the back-end equipment as an application system as an example, an optical module management module of the application system can monitor the light receiving and light emitting conditions of the optical module in real time, and when the light receiving is lower than a certain set value, the optical module management module can judge that the optical module is abnormal.
In one embodiment, the spectroscopic device is configured to monitor a light emission intensity signal of the port, and send out an abnormal port alarm according to the light emission intensity signal and a light emission threshold;
the splitter network manager is used for responding to the received port abnormality alarm and outputting a switching command.
Specifically, when the light-emitting abnormal phenomenon occurs at the light-splitting equipment side, an abnormal port alarm is output, and then the network manager of the splitter can confirm that the link fails and output a switching command.
Taking the optical splitter as an optical power splitter for example, when the splitter network manager detects that the light emitting power of the main interface of the optical power splitter is too low (for example, lower than a set value), the splitter network manager can trigger switching. The primary interface may refer to a port of the primary optical fiber link on the optical power splitter side. In the embodiment of the application, the network manager of the splitter can acquire the light emitting condition of the port of the light splitting equipment side and the light receiving condition of the back-end equipment side, so that the normal link can be automatically switched when the link fails.
Therefore, the embodiment of the application can realize full-automatic switching of the fault link of the optical power splitter, optimize the switching time delay from the minute level to the millisecond level, and improve the switching efficiency and the reliability of an important data link acquisition system.
In order to further explain the scheme of the embodiment of the present application, a specific example is described below, in which a back-end device is an application system, a light splitting device is an optical power splitter, the application system 1 is connected to a port 1 and a port 2 of the optical power splitter, a network manager of the splitter sets the port 1 and the port 2 to be disaster-tolerant backup port groups, the port 1 is a primary port, and the port 2 is a backup port. The automatic switching process after the optical fiber link failure can comprise: (1) when the link 1 fails, the application system 1 will receive abnormal light and alarm to the network manager of the application system. (2) After receiving the alarm, the network manager of the application system automatically initiates a link switching request through the linkage interface. (3) After receiving the link switching request, the network manager of the branching unit automatically issues a command to open the port 2 and close the port 1. (4) The application system 1 receives the light emission of the port 2, and the fault is automatically recovered.
In the above method for switching a faulty link, the optical power splitter sets a disaster recovery backup port group, and a certain optical link in the port group is designated as a main link, and the rest links are designated as backup links. And if the back-end application system detects that the link receives light abnormally, the back-end application system network manager informs the optical power splitter of the link abnormality of the network manager through the linkage interface, and then the optical power splitter network manager issues a command to switch to a standby link, so that the full-automatic switching of the intelligent optical power splitter fault link is realized, the switching time delay is optimized from a minute level to a millisecond level, and the switching efficiency and the reliability of an important data link acquisition system are improved.
