Description
Technical Field
The present disclosure relates to the field of optical fiber communication technologies, and in particular, to a management method, an apparatus, a device, and a storage medium for optical cable splicing alarm.
Background
Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications and utilize one or more optical fibers disposed in a covering jacket as the transmission medium and may be used individually or in groups as telecommunication cable assemblies. That is, the optical cable is a communication cable assembly formed by an optical fiber through a certain process.
Optical cable cutover refers to an access construction technology for building, rebuilding or expanding an optical cable transmission line, and in popular terms, the optical cable is cut off first, and then the cut optical cable is connected after a series of treatments. In an Optical Transmission Network (OTN), each Optical fiber of an Optical cable in the Network can carry a corresponding service, so when the Optical cable is cut off, the service carried by the Optical fiber in the Optical cable may be directly affected, for example, a voice call is not normal, and a Network is not normal. At this time, the system for monitoring the service carried by the optical fiber in the optical cable generates an alarm and sends a fault work order to a line maintenance personnel for processing.
In order to avoid the problem of dispatching due to daily cutover, maintenance personnel can perform marking (cutting identification) on the affected network elements in the OTN network before the cutover. Thus, within the time window of the cutover, the alarms generated by this part of the network element have corresponding identifications, and the system for monitoring the traffic carried by the optical fiber in the optical cable does not form an order for these identified alarms. However, when the number of network elements affected by daily cutover is large, maintenance personnel need to perform calibration work on the network elements one by one, which is time-consuming and labor-consuming, and also easily leaks or incorrectly marks the network elements, resulting in errors in system alarm dispatch for monitoring the service carried by the optical fiber in the optical cable.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," "third," and "fourth," if any, in the description and claims of this application and the above-described figures are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the OTN network, each optical fiber of the optical cable in the network may carry a corresponding service, so when the optical cable is cut, the service carried by the optical fiber in the optical cable may be directly affected, for example, a voice call is not normal, and a network is not normal. At this time, the system for monitoring the service carried by the optical fiber in the optical cable generates an alarm and sends a fault work order to a line maintenance personnel for processing.
In order to avoid the problem of dispatching due to daily cutover, maintenance personnel can perform marking (cutting identification) on the affected network elements in the OTN network before the cutover. Thus, within the time window of the cutover, the alarms generated by this part of the network element have corresponding identifications, and the system for monitoring the traffic carried by the optical fiber in the optical cable does not form an order for these identified alarms.
The standard work mode of the existing OTN network has two types: one is EMS standard work, which aims at all network elements on the whole set of EMS; another is network element standardization, which aims at specific network elements. When daily cutover affects more network elements but is not suitable for EMS marking work and network element marking work, maintenance personnel need to mark the network elements one by one, and particularly for OTN networks across provinces or cities across regions, maintenance personnel of related branch companies of two provinces need to mark work when the OTN networks across provinces are cutover. When the cross-city is cut off, maintenance personnel of two different branch companies in the province need to perform standard work. Therefore, the existing network element labeling method is time-consuming and labor-consuming, and is easy to label missing or label missing network elements, which results in errors in system alarm dispatch for monitoring services carried by optical fibers in optical cables.
In order to solve the above problem, an embodiment of the present application provides a management method for an optical cable cutover alarm, which can determine a to-be-processed optical regeneration section to which a to-be-cut point of an optical cable in an OTN network belongs after the to-be-cut point of the optical cable is obtained, and further determine a to-be-processed optical reuse section to which the to-be-processed optical regeneration section belongs, so that a cutover identifier is added to a network element affected by the to-be-cut point in the optical reuse section, and an alarm generated by the network element in the OTN network is managed according to the cutover identifier.
Optionally, the management method for optical cable cutover alarm provided by the embodiment of the present application may be applied to an application scenario as shown in fig. 1. Fig. 1 only describes, by way of example, one possible application scenario of the management method for optical cable cutover alarms provided in the embodiment of the present application, and the application scenario of the management method for optical cable cutover alarms provided in the embodiment of the present application is not limited to the application scenario shown in fig. 1.
Fig. 1 is a schematic diagram of a management system architecture of an optical cable cutover alarm. In fig. 1, the architecture may include a dispatch system 101, a resource system 102, and an OTN device management system 103.
It is to be understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation to the management architecture of the cable cut alarm. In other possible embodiments of the present application, the foregoing architecture may include more or less components than those shown in the drawings, or combine some components, or split some components, or arrange different components, which may be determined according to practical application scenarios, and is not limited herein. The components shown in fig. 3 may be implemented in hardware, software, or a combination of software and hardware.
In a specific implementation process, the dispatch system 101 may obtain a to-be-cleaved point of an optical cable in the OTN network, determine a to-be-processed optical regeneration section to which the to-be-cleaved point of the optical cable belongs, and determine a to-be-processed optical reuse section to which the to-be-processed optical regeneration section belongs, thereby adding a cleaving identifier to a network element affected by the to-be-cleaved point in the optical reuse section, and managing an alarm generated by the network element in the OTN network according to the cleaving identifier. For example, the dispatch system 101 adds the cutover identifier to the alarm generated by the network element with the cutover identifier during the cutover. When the alarm with the cutover identification is detected, the dispatch system 101 does not generate a dispatch to the alarm, so that the problems that maintenance personnel need to perform laboring to network elements one by one when the conventional cutover is performed daily, time and labor are consumed, label missing or label missing of the network elements is easy, and subsequent alarm dispatch is wrong are solved.
The dispatch system 101 may have other functions besides the above functions. For example, as shown in fig. 2, the dispatch system 101 may further collect relevant resource data of the OTN network, and construct an OTN network topology map based on the resource data, where a transmission segment is divided in the OTN network topology map, and the transmission segment includes the optical regeneration segment and the optical multiplexing segment. In this way, after the optical cable to-be-cut point in the OTN network is obtained, the dispatch system 101 determines, based on the divided transmission paragraphs, the to-be-processed optical regeneration section to which the optical cable to-be-cut point belongs, determines the to-be-processed optical reuse section to which the to-be-processed optical regeneration section belongs, and adds a cut identifier to a network element affected by the to-be-cut point in the optical reuse section, so as to manage an alarm generated by the network element in the OTN network according to the cut identifier.
In addition, the operations of collecting the resource data of the OTN network, constructing the OTN network topology diagram, and dividing the transmission paragraphs in the OTN network topology diagram are completed by the dispatch system 101, the resource system 102, and the OTN device management system 103. For example, the resource system 102 may collect resource data related to the OTN network through the OTN device management system 103. Then, the resource system 102 performs network connection according to the acquired resource data to generate an OTN network topology map, divides the OTN network topology map into an optical regeneration section and an optical multiplexing section, and sends corresponding information to the dispatch system 101, for example, sends the optical regeneration section and the optical multiplexing section divided in the OTN network topology map to the dispatch system 101. After the optical cable to-be-cut point in the OTN network is obtained, the dispatch system 101 determines the optical regeneration section to be processed to which the optical cable to-be-cut point belongs based on the optical regeneration section and the optical reuse section divided in the OTN network topology map, determines the optical reuse section to be processed to which the optical regeneration section to be processed belongs, and adds a cut identifier to a network element affected by the to-be-cut point in the optical reuse section, so that the alarm generated by the network element in the OTN network is managed according to the cut identifier.
It should be understood that the system architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
The technical solutions of the present application are described below with several embodiments as examples, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 3 is a schematic flow chart of a management method for an optical cable cutover alarm provided in an embodiment of the present application, where an execution main body in this embodiment may be the dispatch system 101 in fig. 1, and a specific execution main body may be determined according to an actual application scenario, which is not particularly limited in the embodiment of the present application. As shown in fig. 3, the management method for optical cable cutover alarm provided in the embodiment of the present application may include the following steps:
s301: and acquiring a to-be-cut joint of the optical cable in the OTN.
Here, the dispatch system may obtain the point to be cut of the optical cable in the OTN network in real time, or may obtain the point to be cut of the optical cable in the OTN network periodically. The acquisition period may be determined according to actual conditions, for example, 24 hours.
For example, the optical cable to-be-cut point may be input into the dispatch system by a maintenance person in advance, that is, the dispatch system receives the optical cable to-be-cut point input by the maintenance person, so as to determine the optical cable to-be-cut point in the OTN network.
In the embodiment of the application, the dispatch system firstly obtains the optical cable to-be-cut point in the OTN network, so that the cut identifier is added to the network element affected by the to-be-cut point subsequently based on the optical cable to-be-cut point, and then the alarm generated by the network element in the OTN network is managed according to the cut identifier, so that time and labor are saved, the probability of missing or wrong label network elements is reduced, and the alarm caused by daily cut is reduced.
S302: and determining an optical regeneration section to be processed to which the optical cable point to be cut belongs in the OTN according to the optical cable point to be cut, wherein the optical regeneration section includes a section between an OLA network element and an adjacent OLA network element in the OTN and a section between the OLA network element and an adjacent OADM network element in the OTN.
S303: and determining a to-be-processed optical multiplexing section to which the to-be-processed optical regeneration section belongs in the OTN according to the to-be-processed optical regeneration section, wherein the optical multiplexing section comprises a section between an OADM network element and an adjacent OADM network element in the OTN.
Illustratively, as shown in fig. 4, in the OTN network, the optical regeneration segment includes segments between the OLA network element and the adjacent OLA network element, between the OLA network element and the adjacent OADM network element, and the optical multiplexing segment includes segments between the OADM network element and the adjacent OADM network element. To distinguish between the two network elements, in fig. 4, the OLA network elements are identified by triangles and the OADM network elements are identified by squares, and to distinguish between different OLA network elements and different OADM network elements, in the figure, the identification A, B, C … is added in the triangles for different OLA network elements and the identifications 1, 2 … are added in the squares for different OADM network elements. In FIG. 4, there are 4 optical regeneration sections 1-A, A-B, B-C and C-2, there are 1 optical multiplexing section 1-2, and the optical regeneration sections 1-A, A-B, B-C and C-2 belong to the optical multiplexing sections 1-2. Wherein, the OLA network element and the OADM network element are two different types of network elements in the OTN network respectively.
Here, if the point to be cut of the optical cable in the OTN network obtained by the above described dispatching system is between the OLA network elements A, B of fig. 4. When the optical cable is cut at the point to be cut, A-B are interrupted, A can not receive the light of B and can not emit light to 1, similarly, B can not receive the light of A and can not emit light to C, C can not receive the light of B and can not emit light to 2, so that 1, A, B, C and 2 can not receive light, and all alarms are generated. The existing standard work mode needs a station A maintenance personnel to carry out network element standard work on 1, A, B, C and 2 one by one. In actual operation, a single optical cable carries many transmission systems, up to dozens or even dozens, and there are many network elements that need to be standardized. If the OTN network is across provinces or cities, e.g., network element 1, a is in the first province and network element B, C, 2 is in the second province. When the cross province is cut off, maintenance personnel of related branch companies of two provinces need to perform labor marking, and similarly, when the cross city is cut off, the maintenance personnel of two different branch companies in the province need to perform labor marking, time and labor are consumed, and label missing or label missing network elements are easy to occur, so that a system for monitoring the service borne by the optical fiber in the optical cable gives an alarm and sends a list to be wrong.
In this embodiment of the application, the dispatch system may determine, based on the optical cable to-be-cleaved point, a to-be-processed optical regeneration section, that is, an optical regeneration section a-B, to which the optical cable to-be-cleaved point belongs, and further determine, according to the to-be-processed optical regeneration section, a to-be-processed optical multiplexing section, that is, an optical multiplexing section 1-2, so that a cutover identifier is added to a network element affected by the to-be-cleaved point in the optical multiplexing section 1-2, that is, a cutover identifier is added to the network elements 1, A, B, C, and 2, and according to the cutover identifier, an alarm generated by the network elements in the OTN network is managed.
S304: and adding cutover marks to all network elements in the optical multiplexing section to be processed and network elements at two ends of the optical multiplexing section to be processed.
Here, after determining the optical multiplexing segment to be processed to which the optical regeneration segment to be processed belongs, the dispatch system adds cutover identifiers to all network elements in the optical multiplexing segment to be processed and network elements at both ends of the optical multiplexing segment to be processed, that is, adds cutover identifiers to network elements affected by a cutover point, so as to manage alarms generated by network elements in the OTN network subsequently according to the cutover identifiers.
Illustratively, as shown in fig. 4, the optical regeneration section to be processed to which the optical cable point to be cut belongs is an optical regeneration section a-B, the optical multiplexing section to be processed to which the optical regeneration section a-B belongs is an optical multiplexing section 1-2, and when the optical cable point to be cut is cut, the network elements 1, A, B, C, 2, that is, all the network elements A, B, C in the optical multiplexing section 1-2, and the network elements 1, 2 at both ends of the optical multiplexing section 1-2, are affected. Therefore, the dispatch system adds the cutover identifier to the network elements 1, A, B, C, 2, and then manages the alarm generated by the network element in the OTN network based on the cutover identifier.
In addition, the cutover identifier may include fields such as a branch, a label header, a cutover person, a contact phone, a cutover start time, a cutover end time, a label start time, a label end time, an affiliated transmission system, an affiliated reproduction segment, and the like, and the billing system may further set an effective time of the cutover identifier, for example, a cutover time window.

The cutting identifier is used for adding the cutting identifier to all network elements in the optical multiplexing section to be processed and alarms generated by the network elements at two ends of the optical multiplexing section to be processed during the cutting of the optical cable joint to be cut. For example, taking the example of fig. 4 above, the network elements 1, A, B, C, 2 generate an alarm during the period when the staff member cuts the splice point of the optical cable to be cut in the optical regeneration sections a-B, and the cut identifier is added to the alarm.
And after the dispatch system generates an alarm in the network element in the OTN, detecting whether the cutover identifier exists in the alarm generated by the network element in the OTN, and if so, indicating that the alarm is generated by daily optical cable cutover, stopping dispatching the alarm. For example, taking the above fig. 4 as an example, when the staff performs the optical cable cutting at 0 points a-B of 12 days in 2 months, the network elements 1, A, B, C, 2 generate an alarm. And the order dispatching system detects whether the cutover identifier exists in the alarm or not, and stops generating the order dispatching for the alarm if the cutover identifier exists in the alarm.

In addition, in the embodiment of the present application, when determining an optical regeneration segment to be processed in the OTN network according to the point to be cut of the optical cable, it is further considered to obtain resource data of the OTN network, and further generate an OTN network topology map according to the resource data, and determine the optical regeneration segment to be processed in the OTN network topology map according to the point to be cut of the optical cable. Fig. 5 is a flowchart illustrating another management method for optical cable cutover alarm according to an embodiment of the present application. As shown in fig. 5, the method includes:

Step S501 is the same as the implementation of step S301, and is not described herein again.
S502: and acquiring resource data of the OTN, wherein the resource data comprises network element information in the OTN, intra-network element connection information in the OTN and inter-network element connection information in the OTN.
The OTN network element information includes a branch company, a network element name, a network element type, information of a machine room where the network element is located, and the like. The connection information in the OTN network element includes a network element name, a card name of the optical circuit board, a port number, and the like. The network element types comprise OLA and OADM, wherein the OADM comprises FOADM and ROADM, and the internal connection information of different types of network elements is different.

S503: and generating an OTN network topology map according to the network element information in the OTN network, the intra-network element connection information in the OTN network and the inter-network element connection information in the OTN network.
Here, the dispatch system may perform network connection according to the resource data obtained in step S502 to generate an OTN network topology.
For example, the above dispatch system may use each network element as a network node, use each connection fiber between network elements and in a network element as a network connection, and connect the network element OA boards at two ends of the link, so as to generate a topology diagram of the OTN network. For example, as shown in fig. 6, the OLA network elements are identified by triangles, the OADM network elements are identified by squares, and in the figure, the identifier A, B, C … is added in the triangles for different OLA network elements, and the identifiers 1 and 2 … are added in the squares for different OADM network elements.

In this embodiment of the application, after the dispatch system generates the OTN network topology map, a transmission segment may be divided in the OTN network topology map, where the transmission segment includes the optical regeneration segment and the optical multiplexing segment, and further, an optical regeneration segment identifier may be added to the optical regeneration segment, and an optical multiplexing segment identifier may also be added to the optical multiplexing segment, so that the optical regeneration segment to be processed is determined in the OTN network topology map according to the optical cable to-be-cleaved point and the optical regeneration segment identifier. The order dispatching system may also determine the optical multiplexing segment to be processed to which the optical multiplexing segment to be processed belongs in the OTN according to the optical multiplexing segment to be processed and the identifier of the optical multiplexing segment.

S507: and managing the alarm generated by the network element in the OTN according to the cut-over identifier.
Here, taking the topology diagram of the OTN network shown in fig. 6 as an example, if the point to be cut of the optical cable is between the OLA network elements A, B in the diagram, as shown in fig. 7, the OTN network "high speed middle ring OTN-1" is interrupted between a and B when the point to be cut of the optical cable is cut, a cannot receive the light of B and does not emit light to 1, and similarly, since B cannot receive the light of a and does not emit light to C, C cannot receive the light of B and does not emit light to 2, thus, 1, A, B, C, and 2 cannot receive light. The dispatch system may determine, based on the optical cable to-be-cleaved point, a to-be-processed optical regeneration section, that is, an optical regeneration section a-B, to which the optical cable to-be-cleaved point belongs, and further determine, according to the to-be-processed optical regeneration section, a to-be-processed optical multiplexing section, that is, an optical multiplexing section 1-2, so that a cleaving identifier is added to a network element affected by the to-be-cleaved point in the optical multiplexing section 1-2, that is, a cleaving identifier is added to the network element 1, A, B, C, or 2, and an alarm generated by the network element in the OTN network is managed according to the cleaving identifier.
Except for the above, the implementation manners of steps S505 to S507 are the same as those of steps S303 to S305, and are not described herein again.
According to the optical cable to-be-cut point, when the optical regeneration section to be processed is determined in the OTN, the resource data of the OTN are obtained, an OTN network topological graph is generated according to the resource data, the optical regeneration section to be processed is determined in the OTN network topological graph according to the optical cable to-be-cut point, the processing process is simple, the optical regeneration section to be processed, to which the optical cable to-be-cut point determined through the OTN network topological graph belongs, is accurate, and the accuracy of subsequent processing is improved. In addition, after the optical cable to-be-cut point in the OTN network is obtained, the to-be-processed optical regeneration section to which the optical cable to-be-cut point belongs is determined, and then the to-be-processed optical reuse section to which the to-be-processed optical regeneration section belongs is determined, so that a cut-over identifier is added to a network element affected by the to-be-cut point in the optical reuse section, and alarms generated by the network element in the OTN network are managed according to the cut-over identifier.
In addition, in the embodiment of the present application, before adding the cutover identifier to all network elements in the optical multiplexing segment to be processed and network elements at two ends of the optical multiplexing segment to be processed, it is further determined whether the optical regeneration segment to be processed is the main route of the optical multiplexing segment to be processed, and if so, the cutover identifier is added to all network elements in the optical multiplexing segment to be processed and network elements at two ends of the optical multiplexing segment to be processed.

If the optical regeneration section to be processed is the main route of the optical multiplexing section to be processed, the dispatch system may add a main route identifier to the optical regeneration section to be processed. If the optical regeneration segment to be processed is the backup route of the optical multiplexing segment to be processed, the dispatch system may add a backup route identifier to the optical regeneration segment to be processed. Therefore, the subsequent dispatch system can determine whether the optical regeneration section to be processed is the primary route of the optical multiplexing section to be processed based on the added primary route identifier or the added standby route identifier.
