[0045] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

At the same time, the term "and / or" used in the specification includes any and all combinations of the related listed items.

[0050] With the application of big data journey card and the like, higher requirements are put forward for the reliability of the DPI system. In the event of optical link failure of the intelligent optical power splitter and the backend application system, the traditional technology can only be manually switched, and has the disadvantages of long switching time, high risk of data loss and the like. Taking port 1 and port 2 of the application system 1 accessing the optical power splitter as an example, the current manual switching process after the optical fiber link failure includes: ① When link 1 fails, the application system 1 will appear abnormal light receiving phenomenon, and will alarm the application system network management. ② After receiving the application system network management alarm, the relevant personnel of the application system network management informs the optical power splitter network management personnel to switch the link. ③ The optical power splitter network management personnel opens port 2 and closes port 1 by issuing a command through the optical power splitter network management. ④ The application system 1 receives the light emission of port 2 and recovers from the failure.

[0051] At present, the link between the optical power splitter and the backend application system can only be manually switched to recover from failure after the link fails, and there is no automatic means, so there are disadvantages such as low switching efficiency, delayed switching and data loss.

[0052] The fault link switching method provided by the embodiments of the present application can be applied to, for example Figure 1The application environment shown. Among them, the shunt network management 102 and the application system network management 104 increase the linkage interface, the shunt network management 102 communicates with the application system network management 104 through the linkage interface, and there are at least two optical fiber links between the optical splitting equipment managed by the shunt network management and the backend equipment managed by the application system network management.

[0053] As Figure 1 shown, taking the optical power shunt as an example, the application system 1 connects the port 1 and the port 2 of the optical power shunt, forming two optical fiber links; further, the application system 2 connects the port 3 of the optical power shunt, and the application system 3 connects the port 4 of the optical power shunt. Exemplarily, if the backend application system detects that the link receives light abnormally, the application system network management 104 informs the shunt network management 102 of the link abnormality through the linkage interface, and then the shunt network management 102 issues a command to switch to a normal link.

[0054] Optionally, the linkage interface can include at least one of an RPC (Remote Procedure Call) interface, an HTTP (Hyper Text Transfer Protocol) interface, a webservice interface, and a RESTful (Representational State Transfer) interface.

[0056] Optionally, as Figure 1 shown, the backend application system can refer to application system 1 to application system 3, and it should be noted that the number of backend application systems can be multiple, and the present application has no limitation on this. Further, the backend application system can refer to a convergence shunt, a DPI collection server and other backend devices, that is, the backend device in the present application can refer to the backend application system.

[0057] The embodiment of the application can realize full-automatic switching of a fault link of an optical power splitter. Exemplarily, the embodiment of the application can be applied to 5G (5th Generation Mobile Communication Technology) / fixed network DPI system disaster recovery capability improvement, to realize all-year lossless guarantee service for traffic collection users and customers, and to further improve industry competitiveness.

[0058] In one embodiment, as shown in Figure 2 , a fault link switching method is provided, which is applied to an application system network management in Figure 1 for example, and includes the following steps.

[0059] In step 202, a link switching request is output in response to receiving a link abnormality alarm transmitted by a backend device.

[0060] The link switching request is used to instruct the splitter network management to output a switching command. The switching command is used to instruct the optical splitting device to switch from a fault link corresponding to the link abnormality alarm in at least two optical fiber links to a normal link in the at least two optical fiber links.

[0061] Specifically, the application system network management outputs a link switching request to the splitter network management in the case of receiving a link abnormality alarm transmitted by the backend device, to inform the splitter network management that there is an optical fiber link abnormality at present, and to significantly reduce the switching delay. The link abnormality alarm can be output by the backend device in the case of an optical fiber link failure. Exemplarily, when one optical fiber link fails, the port of the backend device will have a light receiving abnormality phenomenon, and the backend device can then alarm the application system network management.

[0062] In the case of the light receiving abnormality phenomenon, the backend device can alarm the application system network management.

[0063] Optionally, the splitter network management can automatically issue a switching command to the optical splitting device in response to the link switching request in the case of receiving the link switching request. The optical splitting device switches from a fault link corresponding to the link abnormality alarm in at least two optical fiber links to a normal link in the at least two optical fiber links according to the received switching command, to guarantee that the link can be automatically switched to a normal link (for example, a backup link) in the case of a link failure, to realize full-automatic switching of a fault link of the backend device, to optimize the switching delay from the minute level to the millisecond level, and to improve the switching efficiency and the reliability of an important data link collection system.

[0064] Exemplarily, the fault link can be a primary optical fiber link in the at least two optical fiber links, and the normal link can be a backup optical fiber link in the at least two optical fiber links. Alternatively, the primary optical fiber link and the backup optical fiber link can be obtained by marking each output port of the optical splitter device through a splitter network.

[0065] In one of the embodiments, the application system network management is connected to the splitter network management through a linkage interface; and the output link switching request can include:

[0066] Based on the linkage interface, the link switching request is transmitted to the splitter network management; and the linkage interface includes at least one of a remote procedure call protocol (RPC) interface, a hypertext transfer protocol (HTTP) interface, a webservice interface, and a presentation layer state transfer interface.

[0067] Specifically, in the embodiments of the present application, a linkage interface is added between the application system network management and the splitter network management, and then the application system network management can automatically initiate a link switching request through the linkage interface in the case that a link abnormality alarm is transmitted by the backend device, and the splitter network management automatically issues a command to switch to a normal link (for example, a backup link) after receiving the link switching request, so that the fault is automatically recovered.

[0068] Exemplarily, the linkage interface can be RPC, HTTP, webservice, Restful, etc., and the embodiments of the present application do not limit the type of linkage interface. Based on the linkage interface, the embodiments of the present application can realize an automatic switching process after an optical fiber link fault.

[0069] In one of the embodiments, the at least two optical fiber links include a primary optical fiber link and at least one backup optical fiber link.

[0070] The link abnormality alarm is used to represent that the primary optical fiber link has a light receiving abnormality; and the normal link is a backup optical fiber link.

[0071] Specifically, there are at least two optical fiber links between the splitter device managed by the splitter network management and the backend device managed by the application system network management, and the at least two optical fiber links include a primary optical fiber link and at least one backup optical fiber link. Exemplarily, a certain optical link in the at least two optical fiber links can be designated as a main link (primary optical fiber link), and the remaining links are designated as backup links (backup optical fiber links).

[0072] Exemplarily, the link abnormality alarm is used to represent that the primary optical fiber link has a light receiving abnormality, and when the primary optical fiber link fails, the backend device will have a light receiving abnormality phenomenon, and then an alarm is given to the application system network management. Alternatively, the normal link is a backup optical fiber link, and the embodiments of the present application can realize full-automatic switching of an intelligent optical power splitter fault link, so that the backup link can be automatically switched when a link fault occurs.

[0073] In one embodiment, the switching command carries the port identifier corresponding to the primary fiber link and the port identifier corresponding to the backup fiber link.

[0074] The switching command is used to instruct the optical splitting device to close the port corresponding to the primary fiber link and open the port corresponding to the backup fiber link.

[0075] Specifically, the splitter network management automatically issues the switching command after receiving the link switching request, which can carry the port identifier corresponding to the primary fiber link and the port identifier corresponding to the backup fiber link. Then, the optical splitting device can open a certain port and / or close a certain port according to the switching command, thereby realizing link switching.

[0076] The above fault link switching method can realize full-automatic switching of the intelligent optical power splitter fault link, optimize the switching delay from the minute level to the millisecond level, and improve the switching efficiency and the reliability of the important data link acquisition system.

[0077] In one embodiment, as shown in Figure 3 , a fault link switching method is provided, which is described by taking the splitter network management in Figure 1 as an example, including the following steps:

[0078] Step 302, in response to receiving the link switching request transmitted by the application system network management, outputting a switching command; wherein the link switching request is obtained by processing the link abnormal alarm transmitted by the backend device through the application system network management;

[0079] The switching command is used to instruct the optical splitting device to switch from the fault link corresponding to the link abnormal alarm in the at least two fiber links to the normal link in the at least two fiber links.

[0080] Specifically, the splitter network management receives the link switching request transmitted by the application system network management, and then responds to the link switching request to issue the switching command to the optical splitting device. Then, the optical splitting device can switch from the fault link corresponding to the link abnormal alarm in the at least two fiber links to the normal link in the at least two fiber links. The embodiment of the present application can improve the switching efficiency and the reliability of the important data link acquisition system.

[0081] Illustratively, the backend device sends the link abnormal alarm to the application system network management, and then the application system network management outputs the link switching request. Optionally, the splitter network management can receive the link switching request transmitted by the application system network management through the linkage interface, and the linkage interface can include at least one of the remote procedure call protocol RPC interface, the hypertext transfer protocol HTTP interface, the webservice interface, and the presentation layer state transfer interface.

[0082] The embodiment of the application adds a linkage interface between the shunt network management and the application system network management. If the rear-end application system detects abnormal light collection of the link, the rear-end application system network management informs the shunt network management of the link abnormality through the linkage interface, and then the shunt network management issues a command to switch to a normal link (for example, a backup link), thereby optimizing the switching delay from the minute level to the millisecond level, and realizing full-automatic switching of the optical power shunt failure link.

[0083] In one of the embodiments, the method further comprises:

[0084] In response to receiving the port abnormality alarm transmitted by the light splitting device, outputting a switching command.

[0085] Specifically, when the shunt network management receives the port abnormality alarm transmitted by the light splitting device, it can be confirmed that the light splitting device detects that the light emission intensity of the port is too low (for example, the light emission intensity signal is lower than the light emission threshold value), and then outputs a switching command, so that the light splitting device switches to a normal link. In the embodiment of the application, the light emission intensity signal can refer to the light emission power, and the light emission threshold value can be a set value, which is not limited in the embodiment of the application.

[0086] Taking the light splitting device as an optical power shunt for example, the shunt network management will also switch when detecting that the light emission power of the primary interface of the optical power shunt is too low (for example, lower than the set value). In the embodiment of the application, the shunt network management can obtain the light emission condition of the port on the light splitting device side, and can also obtain the light collection condition of the rear-end device side, so as to guarantee that the normal link can be automatically switched when the link fails, thereby realizing full-automatic switching of the failure link of the rear-end device, optimizing the switching delay from the minute level to the millisecond level, and improving the switching efficiency and the reliability of the important data link acquisition system.

[0087] In one of the embodiments, the at least two optical fiber links include a primary optical fiber link and at least one backup optical fiber link; the method can further comprise:

[0088] Determining the disaster recovery backup port group information of each output port of the light splitting device; the disaster recovery backup port group information includes the port identifier of the output port corresponding to the primary optical fiber link, and the port identifier of the output port corresponding to each backup optical fiber link.

[0089] Specifically, there are at least two optical fiber links between the light splitting device managed by the shunt network management and the rear-end device managed by the application system network management, wherein one of the at least two optical fiber links can be designated as a primary link (primary optical fiber link), and the remaining links are designated as backup links (backup optical fiber links). The embodiment of the application can realize full-automatic switching of the failure link, and guarantee that the backup link can be automatically switched when the link fails.

[0090] Exemplarily, the shunt network management device can set a disaster backup port group for the optical power shunt device, and a certain optical fiber link in the port group is designated as a main optical fiber link, and the rest of the links are designated as backup optical fiber links. Optionally, taking the optical power shunt device as an example, the disaster backup port group can be set for the optical power shunt device, and a certain optical link in the port group is designated as a main link, and the rest of the links are designated as backup links.

[0091] Further, the shunt network management device can determine the disaster backup port group information of each output port of the optical power shunt device, and the disaster backup port group information is used to indicate the main optical fiber link and the backup optical fiber link. Exemplarily, the disaster backup port group information can include the port identifier of the output port corresponding to the main optical fiber link, and the port identifier of the output port corresponding to each backup optical fiber link.

[0092] Taking the optical power shunt device as an example, the shunt network management device can set port 1 and port 2 of the optical power shunt device as a disaster backup port group, wherein the shunt network management device can mark port 1 and port 2 respectively, for example, port 1 is a main port, and port 2 is a backup port.

[0093] The above, the embodiment of the application can intelligently set a disaster backup port group for the optical power shunt device, a certain optical link in the port group is designated as a main link, and the rest of the links are designated as backup links, thereby realizing full-automatic switching of the optical power shunt device (for example, switching to a backup link when a link is abnormal), optimizing the switching delay from minutes to milliseconds, and improving the switching efficiency and the reliability of the important data link acquisition system.

[0094] It should be noted that the specific limitations in the above-mentioned fault link switching method implemented from the perspective of the shunt network management device can be referred to the limitations of the fault link switching method implemented from the perspective of the application system network management device, which will not be repeated here.

[0095] In one of the embodiments, the backend device can include at least one of a convergence shunt, a DPI acquisition server; and the optical power shunt device.

[0096] Specifically, the optical power shunt device managed by the shunt network management device can be an optical power shunt device. The backend device managed by the application system network management device can be a convergence shunt, a DPI acquisition server, etc. The embodiment of the application has no limitation on this.

[0097] In one of the embodiments, the backend device is configured to monitor the received light intensity signal of the port, and send a link abnormality alarm according to the size of the received light intensity signal and the received light threshold.

[0098] Specifically, when the link fails, the rear-end device will have a light receiving abnormal phenomenon, and the rear-end device will alarm the application system network management. Among them, the rear-end device can monitor the light receiving intensity signal of the port to issue a link abnormal alarm according to the size of the light receiving intensity signal and the light receiving threshold. Exemplarily, the light receiving threshold can refer to a certain set value. Alternatively, the light receiving intensity signal can refer to the light receiving power.

[0099] Taking the rear-end device as an example of the application system, the optical module management module of the application system can monitor the light receiving and light emitting of the optical module in real time. When the light receiving is lower than a certain set value, it is judged to be abnormal.

[0100] In one of the embodiments, the light splitting device is used to monitor the light emitting intensity signal of the port, and issue a port abnormal alarm according to the size of the light emitting intensity signal and the light emitting threshold;

[0101] The splitter network management is used to output a switching command in response to receiving the port abnormal alarm.

[0102] Specifically, the port abnormal alarm is output when the light emitting abnormal phenomenon occurs on the light splitting device side, and then the splitter network management can confirm that the link fails, and output the switching command.

[0103] Taking the light splitting device as an optical power splitter, the splitter network management can trigger switching when detecting that the light emitting power of the primary interface of the optical power splitter is too low (such as lower than a set value). The primary interface can refer to the port of the primary optical fiber link on the side of the optical power splitter. In the embodiment of the present application, the splitter network management can obtain the light emitting condition of the port on the side of the light splitting device, and also can obtain the light receiving condition on the side of the rear-end device, so as to guarantee that the normal link can be automatically switched when the link fails.

[0104] In the above, the embodiment of the present application can realize full-automatic switching of the optical power splitter failure link, optimize the switching delay from the minute level to the millisecond level, and improve the switching efficiency and the reliability of the important data link acquisition system.

[0105] In order to further explain the scheme of the embodiment of the present application, a specific example is described below. Taking the rear-end device as the application system and the light splitting device as the optical power splitter as an example, the application system 1 is connected to the port 1 and the port 2 of the optical power splitter, the splitter network management sets the port 1 and the port 2 as a disaster recovery backup port group, the port 1 is the primary port, and the port 2 is the backup port. The automatic switching process after the optical fiber link failure can include: ① When the link 1 fails, the application system 1 will have a light receiving abnormal phenomenon, and will alarm the application system network management. ② After receiving the alarm, the application system network management automatically initiates a link switching request through the linkage interface. ③ After receiving the link switching request, the splitter network management automatically issues a command to open the port 2 and close the port 1. ④ The application system 1 receives the light emitting of the port 2, and the fault is automatically recovered.

[0106] The above fault link switching method, the optical power splitter sets a disaster recovery backup port group, a certain optical link in the port group is designated as a main link, and the remaining links are designated as backup links. A linkage interface is added between the splitter network management and the application system network management.
