Description
Technical Field

Background
Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications by utilizing one or more optical fibers disposed in a covering sheath as a transmission medium and may be used alone or in groups of communication cable assemblies. That is, the optical cable is a communication cable assembly formed by subjecting an optical fiber to a certain process.
The optical cable cutting connection refers to an access construction technology for newly building, rebuilding or expanding an optical cable transmission line, and conventionally, the optical cable is cut off firstly, and then the cut optical cable is connected after a series of treatments. In an optical transmission network (Optical Tranport Network, OTN), since each optical fiber of an optical cable in the network can carry a corresponding service, when the optical fiber is cut, the service carried by the optical fiber in the optical cable may be directly affected, for example, voice call is abnormal, internet surfing is abnormal, and the like. At this point, the system for monitoring the traffic carried by the optical fibers in the cable will generate an alarm and dispatch the faulty work order to the on-line maintenance personnel for processing.

In this way, in the cutting-over time window, the alarms generated by the network elements have corresponding identifications, and the system for monitoring the service carried by the optical fibers in the optical cable can not form a dispatch list for the alarms with identifications. However, when a large number of network elements are affected by daily cutting, maintenance personnel need to mark the network elements one by one, which is time-consuming and labor-consuming, and is easy to miss mark or misplace mark the network elements, so that system alarm dispatch errors for monitoring the business carried by the optical fibers in the optical cable are caused.

Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The terms "first," "second," "third," and "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise 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 an OTN network, since each optical fiber of an optical cable in the network can carry a corresponding service, when the optical cable is cut, the service carried by the optical fiber in the optical cable may be directly affected, for example, voice call is abnormal, internet surfing is abnormal, and the like. At this point, the system for monitoring the traffic carried by the optical fibers in the cable will generate an alarm and dispatch the faulty work order to the on-line maintenance personnel for processing.
In order to avoid the fault dispatch caused by daily cutting, maintenance personnel can mark the affected network elements in the OTN (marking cutting mark) before cutting. In this way, in the cutting-over time window, the alarms generated by the network elements have corresponding identifications, and the system for monitoring the service carried by the optical fibers in the optical cable can not form a dispatch list for the alarms with identifications.
The standard working modes of the existing OTN network are two types: one is EMS standard work, which aims at all network elements on the whole set of EMS; the other is a network element label, which aims at a specific network element. When a plurality of network elements are affected by daily cutting and connecting, but are not suitable for EMS mark work and network element mark work, maintenance personnel need to mark the network elements one by one, and especially for an OTN network of cross province or cross local city, when the cross province is cut and connected, the maintenance personnel of related branch companies of two provinces need to mark the work. When cutting across the city, maintenance personnel of two different branch companies in the province all need standard labor. Therefore, the existing network element labeling method is time-consuming and labor-consuming, and is easy to miss labels or label the network elements in a wrong way, so that system alarm dispatch errors for monitoring the business carried by the optical fibers in the optical cable are caused.
In order to solve the above problems, the embodiments of the present application provide a management method for optical cable cutting alarm, which can determine a to-be-processed optical regeneration section to which an optical cable to-be-cut joint belongs after an optical cable to-be-cut joint in an OTN network is acquired, and further determine a to-be-processed optical multiplexing section to which the to-be-processed optical regeneration section belongs, so that a cutting identifier is added to a network element affected by the to-be-cut joint in the optical multiplexing section, and an alarm generated by the network element in the OTN network is managed according to the cutting identifier.
Optionally, the method for managing the optical cable splicing alarm provided in the embodiment of the present application may be applied to an application scenario as shown in fig. 1. Fig. 1 is only an illustration of one possible application scenario of the method for managing an optical cable splicing alarm according to the embodiment of the present application, and the application scenario of the method for managing an optical cable splicing alarm according to 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 for cable cut alarms. In fig. 1, the architecture may include a dispatch system 101, a resource system 102, and an OTN device management system 103.
It will be appreciated that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the management architecture of the cable cut alarm. In other possible embodiments of the present application, the architecture may include more or fewer components than those illustrated, or some components may be combined, some components may be separated, or different component arrangements may be specifically determined according to the actual application scenario, and the present application 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 an optical cable to-be-cut point in the OTN network, further determine a to-be-processed optical regeneration section to which the optical cable to-be-cut point belongs, and determine a to-be-processed optical multiplexing section to which the to-be-processed optical regeneration section belongs, so as to add a cutting identifier to a network element affected by the to-be-cut point in the optical multiplexing section, and manage an alarm generated by the network element in the OTN network according to the cutting 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 cutting-over mark is detected, the dispatching system 101 does not dispatch the alarm, so that the problem that the maintenance personnel need to mark the network elements one by one in the conventional daily cutting-over process, which is time-consuming and labor-consuming, and easily leaks marks or marks the network elements in a wrong way, thereby causing the follow-up alarm dispatching errors is solved.
The dispatch system 101 may have other functions in addition to the above functions. For example, as shown in fig. 2, the dispatch system 101 may further collect related resource data of the OTN network, and construct an OTN network topology map based on the resource data, where a transmission section is divided in the OTN network topology map, where the transmission section includes the optical regeneration section and the optical multiplexing section. In this way, after the sending system 101 obtains the optical cable to-be-cut point in the OTN network, based on the divided transmission paragraphs, the to-be-processed optical regeneration section to which the optical cable to-be-cut point belongs is determined, the to-be-processed optical multiplexing section to which the to-be-processed optical regeneration section belongs is determined, and a cutting identifier is added to the network element affected by the to-be-cut point in the optical multiplexing section, so that an alarm generated by the network element in the OTN network is managed according to the cutting identifier.
In addition, the above operations of collecting the resource data of the OTN network, constructing the OTN network topology, and dividing the transmission section in the OTN network topology may be completed by the resource system 102 and the OTN device management system 103, in addition to the above-mentioned dispatch system 101. For example, the resource system 102 may perform collection of OTN network related resource data through the OTN device management system 103. Then, the resource system 102 performs network connection according to the collected resource data to generate an OTN network topology map, then divides the OTN network topology map into an optical regeneration segment and an optical multiplexing segment, and sends corresponding information to the dispatch system 101, for example, sends the optical regeneration segment and the optical multiplexing segment divided in the OTN network topology map to the dispatch system 101. After the dispatching system 101 obtains the optical cable to-be-cut point in the OTN network, based on the optical regeneration section and the optical multiplexing section divided in the OTN network topology diagram, determining the to-be-processed optical regeneration section to which the optical cable to-be-cut point belongs, determining the to-be-processed optical multiplexing section to which the to-be-processed optical regeneration section belongs, and adding a cut-over identifier to the network element affected by the to-be-cut point in the optical multiplexing section, thereby managing the alarm generated by the network element in the OTN network according to the cut-over identifier.
It should be understood that, the system architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and are not limited to the technical solution provided in the embodiments of the present application, and those of ordinary skill in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is equally applicable to similar technical problems.
The following description of the technical solutions of the present application will take 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 flow chart of a method for managing an optical cable cutting alarm according to an embodiment of the present application, where an execution body of the embodiment may be the dispatch system 101 in fig. 1, and a specific execution 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 method for managing an optical cable splicing alarm provided in the embodiment of the present application may include the following steps:
s301: and acquiring an optical cable to-be-cut point in the OTN network.
Here, the dispatching system can acquire the optical cable to-be-cut point in the OTN network in real time, and also can periodically acquire the optical cable to-be-cut point in the OTN network. The acquisition period may be determined according to practical situations, for example, 24 hours.
The optical cable to-be-cut point may be an optical cable to-be-cut point that a maintainer inputs to the dispatch system in advance, that is, the dispatch system receives the maintainer input, so as to determine the optical cable to-be-cut point in the OTN network.
In the embodiment of the application, the dispatching system firstly acquires the optical cable to-be-cut joint in the OTN network, so that the cutting-over identifier is added to the network element affected by the to-be-cut joint based on the optical cable to-be-cut joint, and then, according to the cutting-over identifier, the alarm generated by the network element in the OTN network is managed, so that time and labor are saved, the probability of label missing or label misplacement of the network element is reduced, and the alarm caused by daily cutting-over is reduced.
S302: and determining an optical regeneration section to be processed, to which the optical cable to-be-cut joint belongs, in the OTN according to the optical cable to-be-cut joint, wherein the optical regeneration section comprises a section between a middle OLA network element and an adjacent OLA network element of 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 segment to which the to-be-processed optical regeneration segment belongs in the OTN according to the to-be-processed optical regeneration segment, wherein the optical multiplexing segment comprises a paragraph between an OADM network element and an adjacent OADM network element in the OTN.
Illustratively, as shown in fig. 4, in an OTN network, the optical regeneration segment includes a paragraph between an OLA network element and a neighboring OLA network element, and between an OLA network element and a neighboring OADM network element, and the optical multiplexing segment includes a paragraph between an OADM network element and a neighboring OADM network element. To distinguish between two network elements, in fig. 4, OLA network elements are identified by triangles, OADM network elements are identified by squares, and to distinguish between different OLA network elements, and different OADM network elements, in the figure, an identification A, B, C … is added in triangles for different OLA network elements, and an identification 1, 2 … is added in 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 multiplexing sections to which the optical regeneration sections 1-A, A-B, B-C and C-2 belong are all optical multiplexing sections 1-2. Wherein, the OLA network element and the OADM network element are respectively two different types of network elements in the OTN network.
Here, if the optical cable to-be-cut point in the OTN network acquired by the dispatch system is between OLA network elements A, B in fig. 4. When the optical cable is cut at the joint to be cut, the A-B is interrupted, the A cannot receive the light of the B and does not emit light to 1, and similarly, the B cannot receive the light of the A and does not emit light to C, the C cannot receive the light of the B and does not emit light to 2, so that the 1, A, B, C and 2 cannot receive the light and all generate alarms. The existing standard working mode needs station A maintenance personnel to carry out network element standard working on 1, A, B, C and 2 one by one. In actual operation, a large number of transmission systems are carried by one optical cable, up to more than ten, even tens of network elements requiring standard engineering. If the OTN network spans provinces or across cities, for example, network element 1, a is in province a and network element B, C, 2 is in province b. When the cross-province is cut, maintenance personnel of related branch companies of two provinces need to mark the labor, and similarly, when the cross-province is cut, maintenance personnel of two different branch companies in the province need to mark the labor, time and labor are consumed, mark omission or wrong mark network elements are easy to occur, and system alarm dispatch errors for monitoring the business borne by the optical fibers in the optical cable are caused.
In this embodiment of the present application, the dispatching system may determine, based on the optical cable to-be-cut point, a to-be-processed optical regeneration section, that is, an optical regeneration section a-B, where the optical cable to-be-cut point belongs to, and further determine, according to the to-be-processed optical regeneration section, an to-be-processed optical multiplexing section, that is, an optical multiplexing section 1-2, so that a cutting identifier is added to a network element affected by the to-be-cut point in the optical multiplexing section 1-2, that is, a cutting identifier is added to the network element 1, A, B, C, 2, and according to the cutting identifier, an alarm generated by the network element in the OTN network is managed, so that a processing process is simple and convenient, a processing result is more accurate relative to a manual label of a maintainer, and a subsequent alarm dispatching error rate is lower.
S304: and adding a cutting-over identifier to all network elements in the optical multiplexing section to be processed and the network elements at two ends of the optical multiplexing section to be processed.
