The internal subnetwork system is usually connected to multiple transmission devices of the corresponding type by pipeline resources such as optical cables. According to the importance of the services carried by the subnetwork system and different networking forms, different disaster recovery protection schemes can be deployed. When the main route fails, the services carried on the subnetwork system can be automatically switched to the backup route to ensure the safe operation of the services.

The existing system cannot avoid the contradiction between multiple different logical paths on the network management topology and the same physical route of the optical cable laying, and once a physical same-route failure occurs, double-breakage on the main and backup paths of a single or multiple or different level subnetwork systems, protection failure and other situations will occur, thereby causing a large area of service withdrawal.

[0052] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings.

[0053] It should be noted that the terms "first", "second", and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0054] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data for analysis, stored data, displayed data, etc.) and signals involved in the present disclosure are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards of relevant countries and regions.

[0055] The acquisition, storage, use, processing, etc. of data in the technical solutions of the present disclosure all comply with the relevant provisions of national laws and regulations.

[0056] It should be noted that in the embodiments of the present disclosure, there may be some software, components, models, etc. in the industry, which should be considered as exemplary, and their purpose is only to illustrate the feasibility of the implementation of the technical solutions of the present disclosure, but it does not mean that the applicant has or will necessarily use the scheme.

[0057] In the related art, a transmission network is a basic base for carrying wireless, broadband, dedicated line and other services, composed of many subnetwork systems such as PTN / SPN / OTN / SDH, and a plurality of corresponding type transmission devices are connected by pipeline resources such as optical cables inside these subnetwork systems. According to the importance of the services carried and different networking forms, different disaster recovery protection schemes are deployed. When the main route fails, the services carried on the system can be automatically switched to the standby route to ensure the safe operation of the services. However, at present, the networking of devices and optical cables is becoming larger and more complex, and the system cannot avoid the contradiction between the multiple different logical paths on the network management topology and the actual use of the optical cable laying physical route. The failure of the physical same route can cause double breakage and protection failure on the main and standby paths of a single or multiple or different level subnetwork system, thereby causing a large area of service withdrawal.

[0058] In view of the above problems, major communication operators and related manufacturers provide different same route analysis methods between two transmission optical cables / optical paths and inside a single transmission subnetwork system. The existing analysis method for transmission optical cable same route using frequency as an identification feature analyzes the level and stays in the optical path group constructed by the optical path routing and topology link of the subnetwork system, does not master the use distribution of the full amount of optical cables and their underlying supporting sections (optical cable routing) on all transmission subnetwork systems, and does not make global consideration and analysis on the same cable same route and different cable same route of the full amount of transmission subnetwork systems. That is, the related art at least has the following technical problems:

[0059] (1) It is not possible to know in advance all the transmission subnetwork systems carried by the optical cable and the same route, and only the passive knowledge after the failure occurs. How to identify all the transmission subnetwork systems corresponding to the optical cable and the same route in advance is a problem to be solved urgently.

[0060] (2) The optimized resources cannot be timely put into the same route hidden danger that threatens the safety of the service the most, and there is no priority for hidden danger remediation. Only one can be found and solved, and the previous method of achieving batch transmission system same route analysis by stacking multiple single system same route analysis is low in efficiency and time-consuming. How to quickly mine the biggest / larger same route hidden danger in the whole network based on full amount analysis is also a problem to be solved urgently.

[0061] Based on this, the embodiments of the present disclosure provide a comprehensive detection method and device for same route hidden dangers in a transmission network, equipment and medium, which not only has the same same route hidden danger troubleshooting capability of the existing method for single / small batch transmission subnetwork systems, but also is suitable for troubleshooting of same route hidden dangers of single / full amount / large batch transmission subnetwork systems.

[0062] The technical solutions provided by the embodiments of the present disclosure are described in detail below with reference to the drawings.

[0063] In the embodiments of the present disclosure, the following fields are used, and the explanations of the fields are as follows:

[0064] Subnet system name (identifier): The system name of each transmission subnet on the transmission network management of different subnets, different types (PTN / SPN / OTN / SDH, etc.), and different device manufacturers is unique in the whole network (for example, XX-XX-branch 1 / branch 2 / core / aggregation / access-PTN / SPN / OTN / SDH ring / system / subnet-sequence number).

[0065] Transmission segment name (identifier): The logical connection between different devices in a single transmission subnet system on the network management can be described by using the source and destination transmission device names and the networking port names (for example, A device name-port name-Z device name-port name), and this set of descriptions is the transmission segment name.

[0066] Cable name (identifier) passed: The cable list actually used by the transmission segment is described in the specific optical path scheme. If the transmission segment actually uses only one direct cable, the field only contains one cable name. If the actual optical path of the transmission segment passes through one or more hops such as optical exchanges, other machine rooms, and is connected by multiple different cables, the field contains a set of cable names.

[0067] Through the optical path scheduling link in the daily network access addition or switching adjustment process, it can be determined which transmission subnet system a single transmission segment belongs to and which logical link it is used for, and the total cable name passed can be accurately mastered (the above information can be obtained from the pipeline resource system). Therefore, a two-dimensional list can be designed to store the basic data, and the collection.counter(container) method can be used to count the frequency of the total cable, take each cable as an index, traverse the basic data, obtain the accurate association of the cable-system-transmission segment, and finally obtain the specific name of each cable, the number of uses, and the distribution of the cable in which specific subnet system and transmission segment. For example, Table 1 shows the specific example:

[0069]

[0070] Figure 1 A flowchart of a method for detecting a same-route hidden danger in a transmission network is provided in the embodiments of the present disclosure. The method can be applied to a server, for example, a single server or a server cluster. As shown in Figure 1 The method for detecting a same-route hidden danger in a transmission network can include the following steps:

[0071] S101, obtaining the association relationship between the total network cable, subnet system, and transmission segment.

[0072] In the embodiments of the present disclosure, when detecting the same route hidden danger in the transmission network, the association relationship between the optical cables, the subnetwork systems and the transmission segments in the whole network can be acquired, that is, the use distribution of the full amount of optical cables in the full amount of systems is acquired. For example, the names of all transmission segments in the whole network and the names of the subnetwork systems to which the transmission segments belong, and the lists of the optical cables passing through the transmission segments can be read in sequence respectively. Based on the names of all transmission segments in the whole network and the names of the subnetwork systems to which the transmission segments belong, and the lists of the optical cables passing through the transmission segments, the association relationship between the optical cables, the subnetwork systems and the transmission segments in the whole network is determined. The association relationship can be used to indicate the specific name of each optical cable, the number of uses of the optical cable, and the distribution of the optical cable in which specific subnetwork systems and transmission segments.

[0073] In a possible implementation, acquiring the association relationship between the optical cables, the subnetwork systems and the transmission segments in the whole network comprises:

[0074] The first list is used to read all transmission segment identifiers in the whole network, the second list is used to read the subnetwork system identifiers to which each transmission segment identifier in the whole network belongs, and the third list is used to read the optical cable identifiers passing through each transmission segment identifier in the whole network. The first list, the second list and the third list are one-dimensional lists.

[0075] Based on the first list, the second list and the third list, a fourth list is constructed. The fourth list is a two-dimensional list, and the fourth list is used to indicate the association relationship between the optical cables, the subnetwork systems and the transmission segments.

[0076] In the embodiments of the present disclosure, when acquiring the association relationship between the optical cables, the subnetwork systems and the transmission segments in the whole network, the first list, the second list and the third list can be used to read all transmission segment identifiers in the whole network, the subnetwork system identifiers to which each transmission segment identifier in the whole network belongs, and the optical cable identifiers passing through each transmission segment identifier in the whole network respectively. The identifiers can be names. Then, the three lists of the first list, the second list and the third list can be constructed into a two-dimensional list of element association sets, that is, a fourth list. The fourth list includes the association relationship between the optical cables, the subnetwork systems and the transmission segments in the whole network.

[0077] As a specific example, the System_Name, the Transmission_Segment_Name and the Cables_Name three one-dimensional lists can be used to read the names of all transmission segments in the whole network and the names of the subnetwork systems to which the transmission segments belong, and the lists of the optical cables passing through the transmission segments (Cables Name) in sequence respectively, and a two-dimensional list Together of element association sets of the three lists is constructed, that is, a fourth list:

[0078] Together[i] = [System_Name[i], Transmission_Segment_Name[i], Cables_Name[i]] (i: 0 ~ total network transmission segment number - 1)

[0079] S102, based on the association relationship among the optical cables in the whole network, the subnetwork systems and the transmission segments, detecting the optical cables that exist the same-cable same-route hidden danger and meet the first preset condition.

[0080] The same-cable same-route hidden danger refers to a hidden danger that a fault of the same optical cable will cause the interruption of the system in two directions.

[0081] In the embodiments of the present disclosure, after obtaining the association relationship among the optical cables in the whole network, the subnetwork systems and the transmission segments, the detection of the same-cable same-route hidden danger can be performed. For example, the distribution analysis result of the whole amount of optical cables in the whole amount of systems can be used to detect the optical cables that exist the same-cable same-route hidden danger and meet the first preset condition. The first preset condition can indicate that a fault of a certain optical cable will cause the interruption of the system in two directions. It can be understood that the same-cable same-route hidden danger detection can be performed on multiple optical cables at the same time.

[0082] In a possible implementation, based on the association relationship among the optical cables in the whole network, the subnetwork systems and the transmission segments, the detection of the optical cables that exist the same-cable same-route hidden danger and meet the first preset condition comprises:

[0083] The frequency of each optical cable identifier is counted by applying the counter container to the optical cable identifier;

[0084] Based on the frequency of each optical cable identifier, the corresponding frequency, the belonging subnetwork identifier and the belonging transmission segment identifier of each optical cable identifier are counted in the fourth list;

[0085] Based on the corresponding frequency, the belonging subnetwork identifier and the belonging transmission segment identifier of each optical cable identifier, the number n1 of the transmission segments belonging to the single subnetwork system of each optical cable identifier and the number n2 of the subnetwork system influence of each optical cable identifier are counted;

[0086] For the i-th optical cable identifier, if the number n1 of the transmission segments belonging to the same subnetwork system of the i-th optical cable identifier is greater than the first preset threshold value, the number n2 of the subnetwork system influence of the i-th optical cable identifier is equal to the original n2 value plus 1; wherein i∈(1, M), M is the total number of optical cables;

[0087] If the frequency of the i-th optical cable identifier is greater than or equal to the second preset threshold value, and the number n2 of the subnetwork system influence of the i-th optical cable identifier is greater than or equal to the second threshold value, it is determined that the optical cable corresponding to the i-th optical cable identifier exists the same-cable same-route hidden danger that will cause the interruption of multiple subnetwork systems in two directions;

[0088] In a case that the frequency of the i-th optical cable identifier is greater than or equal to the second preset threshold, and the number n2 of the subnet system affected by the i-th optical cable identifier is less than the second preset threshold, it is determined that the optical cable corresponding to the i-th optical cable identifier exists a same-cable same-route risk of causing a single subnet system to be interrupted in two directions.

[0089] In an embodiment of the present disclosure, when detecting the optical cable with the same-cable same-route risk meeting the first preset condition based on the association relationship among the optical cables, the subnet systems and the transmission segments, the frequency of each optical cable can be counted by applying a counter collection.counter to the optical cable identifier list. Then, the frequency of each optical cable identifier, the subnet identifier and the transmission segment identifier corresponding to the optical cable identifier can be counted based on the frequency of each optical cable identifier, so as to obtain the distribution of the optical cables in the whole network system. Thereafter, the number n1 of the transmission segments in the same subnet system corresponding to the same optical cable can be counted by using an integer variable n1, and the number n2 of the subnet systems affected by the same optical cable can be counted by using an integer variable n2, and the initial values of n1 and n2 are both 0. For a certain optical cable, for example, the i-th optical cable identifier, if the number n1 of the transmission segments in the single subnet system to which the i-th optical cable identifier belongs is greater than the first preset threshold, the number n2 of the subnet systems affected by the optical cable corresponding to the i-th optical cable identifier is equal to the original n2 value plus 1. The first preset threshold can be set to 2, for example.

[0090] It is further determined whether the frequency of the i-th optical cable identifier is greater than or equal to the second preset threshold, and whether the number n2 of the subnet systems affected by the i-th optical cable identifier is greater than or equal to the second threshold. The second preset threshold can be set to 2, for example. If the frequency of the i-th optical cable identifier is greater than or equal to the second preset threshold, and the number n2 of the subnet systems affected by the i-th optical cable identifier is greater than or equal to the second threshold, it is considered that the optical cable corresponding to the i-th optical cable identifier exists a same-cable same-route risk of causing multiple subnet systems to be interrupted in two directions. If the frequency of the i-th optical cable identifier is greater than or equal to the second preset threshold, and the number n2 of the subnet systems affected by the i-th optical cable identifier is less than the second preset threshold, it is considered that the optical cable corresponding to the i-th optical cable identifier exists a same-cable same-route risk of causing a single subnet system to be interrupted in two directions. In this way, the same-route risk detection of the optical cable corresponding to each optical cable identifier can be completed. In this way, the collection.counter container method is used, and the counter is suitable for a scenario in which the number of occurrences of an element needs to be counted quickly. The counting process only needs to be iterated once, which is fast and simple. Therefore, based on the association relationship among the network support segments, the optical cables, the transmission segments and the systems, the use of the collection.counter container method can effectively improve the efficiency.

[0091] S103, determine the association relationship among the support sections, optical cables, subnetwork systems and transmission sections in the whole network based on the association relationship among the optical cables, subnetwork systems and transmission sections in the whole network and the association relationship between the optical cables and the support sections.

[0092] In the embodiments of the present disclosure, the association relationship between the optical cables and the support sections can also be obtained, for example, pandas or a database can be used to process data to improve the data analysis efficiency. The association relationship between the optical cables and the support sections can be obtained according to the correspondence relationship between the optical cables and the cable sections and the correspondence relationship between the cable sections and the support sections. Then, the association relationship among the support sections, the optical cables, the subnetwork systems and the transmission sections in the whole network is obtained based on the association relationship among the optical cables, the subnetwork systems and the transmission sections in the whole network and the association relationship between the optical cables and the support sections.

[0093] In a possible implementation, the association relationship among the support sections, the optical cables, the subnetwork systems and the transmission sections in the whole network is determined based on the association relationship among the optical cables, the subnetwork systems and the transmission sections in the whole network and the association relationship between the optical cables and the support sections, and includes:

[0094] The association relationship between the optical cables and the support sections is determined according to the correspondence relationship between the optical cables and the cable sections and the correspondence relationship between the cable sections and the support sections. The association relationship between the optical cables and the support sections is represented by a fifth list, and the fifth list is a two-dimensional list.

[0095] The association relationship among the support sections, the optical cables, the subnetwork systems and the transmission sections in the whole network is determined based on the traversal of the fifth list based on the fourth list. The association relationship among the support sections, the optical cables, the subnetwork systems and the transmission sections in the whole network is represented by a sixth list, and the sixth list is a two-dimensional list.

[0096] In the embodiments of the present disclosure, when the association relationship among the support sections, the optical cables, the subnetwork systems and the transmission sections in the whole network is determined based on the association relationship among the optical cables, the subnetwork systems and the transmission sections in the whole network and the association relationship between the optical cables and the support sections, the two-dimensional list Cable_Support with each element as [optical cable name, support section name] can be obtained according to the correspondence relationship between the optical cables and the cable sections and the correspondence relationship between the cable sections and the support sections, that is, the fifth list. Then, the fifth list can be traversed one by one with the optical cable identifier in the fourth list, that is, the two-dimensional list representing the association relationship among the optical cables, the subnetwork systems and the transmission sections as an index. Based on the subnetwork system and transmission section information originally mapped by each optical cable, the support section information of the optical cable is obtained, and the mapping is reversed to obtain the optical cable, the subnetwork system and the like information supported by each support section, that is, [support section name, optical cable name, system name, transmission section name], which is added to a two-dimensional list as an element, that is, the sixth list, which is used to represent the association relationship among the support sections, the optical cables, the subnetwork systems and the transmission sections in the whole network.

[0097] S104, based on the association relationship among the whole network support section, the optical cable, the subnetwork system and the transmission section, detecting the optical cable with the same-cable different-route hidden danger meeting the second preset condition.

[0098] The same-cable different-route hidden danger refers to a route hidden danger that a fault of a same support section will cause interruption in two directions of the system.

[0099] In the embodiments of the present disclosure, after obtaining the association relationship among the whole network support section, the optical cable, the subnetwork system and the transmission section, the detection of the same-cable different-route hidden danger can be performed. For example, according to the use distribution of the support section on the whole network system, the optical cable with the same-cable different-route hidden danger meeting the second preset condition can be detected. The second preset condition can indicate that a fault of a certain support section will cause interruption in two directions of the system. It can be understood that the same-cable different-route hidden danger detection can be performed on multiple support sections at the same time.

[0100] In a possible implementation, based on the association relationship among the whole network support section, the optical cable, the subnetwork system and the transmission section, the support section with the same-cable different-route hidden danger meeting the second preset condition is detected, including:

[0101] The frequency of each support section is counted by using the counter container;

[0102] The frequency of each support section is associated with the optical cable identifier, the subnetwork system identifier and the transmission section identifier associated with each support section to obtain a seventh list;

[0103] Based on the seventh list, the number N1 of transmission sections in the same subnetwork system corresponding to each support section is counted, and the number N2 of subnetwork system influences of each support section is counted.

[0104] For the jth support section, if the number N1 of transmission sections in the same subnetwork system corresponding to the jth support section is greater than or equal to a third preset threshold, the number N2 of subnetwork system influences of the jth support section is updated to the original N2 value plus 1; j∈[1, k], k is the total number of support sections.

[0105] If the frequency of the jth support section is greater than or equal to a fourth preset threshold, and the number N2 of subnetwork system influences of the jth support section is greater than or equal to the fourth preset threshold, it is determined that the jth support section is a same-cable different-route hidden danger that will cause interruption in two directions of multiple subnetwork systems at the same time.

[0106] If the frequency of the jth support section is greater than or equal to the fourth preset threshold, and the number N2 of subnetwork system influences of the jth support section is less than the fourth preset threshold, it is determined that the jth support section is a same-cable different-route hidden danger that will cause interruption in two directions of a single subnetwork system at the same time.

[0107] In the embodiments of the present disclosure, based on the association relationship among the full-network support section, the optical cable, the sub-network system and the transmission section, when the optical cable with the abnormal cable same route hidden danger meeting the second preset condition is detected, the frequency of each support section can be counted by the counter collection. counter. The frequency of each support section is associated with the optical cable identifier, the sub-network system identifier and the transmission section identifier associated with each support section to obtain a seventh list, which is also a two-dimensional list. Then, the seventh list can be traversed based on the frequency of each support section to count the frequency, the sub-network identifier and the transmission section identifier corresponding to each support section to obtain the distribution of the support section on the full-network system. Subsequently, the number of transmission sections in the same sub-network system corresponding to the same support section can be counted by the integer variable N1, and the number of sub-network system influences of the same support section can be counted by the integer variable N2, and the initial values of N1 and N2 are both 0. For a certain support section, for example, the jth support section, if the number of transmission sections in the sub-network system corresponding to the jth support section N1 is greater than or equal to a third preset threshold, the number of sub-network system influences N2 of the support section is updated to the original N2 value plus 1. The third preset threshold can be set to 2, for example.

[0108] It is further determined whether the frequency of the jth support section is greater than or equal to a fourth preset threshold, and whether the number of sub-network system influences N2 of the jth support section is greater than or equal to the fourth preset threshold, and the fourth preset threshold can be set to 2, for example. If the frequency of the jth support section is greater than or equal to the fourth preset threshold, and the number of sub-network system influences N2 of the jth support section is greater than or equal to the fourth preset threshold, it can be considered that the jth support section has an abnormal cable same route hidden danger that can cause multiple sub-network systems to be interrupted in two directions. If the frequency of the jth support section is greater than or equal to the fourth preset threshold, and the number of sub-network system influences N2 of the jth support section is less than the fourth preset threshold, it can be considered that the jth support section has an abnormal cable same route hidden danger that can cause a single sub-network system to be interrupted in two directions. In this way, the abnormal route hidden danger detection of each support section can be completed.

[0109] In the embodiments of the present disclosure, the association relationship among the optical cables, the subnetwork systems and the transmission sections in the whole network is acquired; based on the association relationship among the optical cables, the subnetwork systems and the transmission sections in the whole network, an optical cable that meets a first preset condition and has a same-cable same-route hidden danger is detected; wherein the same-cable same-route hidden danger refers to a route hidden danger that a fault of the same optical cable will cause a system interruption in two directions; based on the association relationship among the optical cables, the subnetwork systems and the transmission sections in the whole network and the association relationship between the optical cables and the support sections, the association relationship among the support sections, the optical cables, the subnetwork systems and the transmission sections in the whole network is determined; based on the association relationship among the support sections, the optical cables, the subnetwork systems and the transmission sections in the whole network, a support section that meets a second preset condition and has a different-cable same-route hidden danger is detected. In this way, on the one hand, the same-route hidden danger detection can be applied to a single or small-batch transmission subnetwork system, and on the other hand, the same-route hidden danger detection can be applied to a single or large-batch transmission subnetwork system.

[0110] In some possible implementation manners, after detecting the optical cable that meets the first preset condition and has the same-cable same-route hidden danger, the following processing can be further performed:

[0111] For all the same-cable same-route hidden dangers, the same-cable same-route hidden dangers are displayed after being sorted according to the frequency corresponding to the optical cable and the number of affected subnetwork systems.

[0112] After detecting the support section that meets the second preset condition and has the different-cable same-route hidden danger, the following processing can be further performed:

[0113] For all the different-cable same-route hidden dangers, the different-cable same-route hidden dangers are displayed after being sorted according to the frequency corresponding to the support section and the number of affected subnetwork systems.

[0114] In the embodiments of the present disclosure, after detecting the optical cable that meets the first preset condition and has the same-cable same-route hidden danger, the detection result can be displayed after being sorted according to the frequency of the optical cable and the number of affected subnetwork systems from high to low, and different priorities are distinguished according to the importance of the same-cable same-route hidden danger. Similarly, after detecting the support section that meets the second preset condition and has the different-cable same-route hidden danger, the detection result can be displayed after being sorted according to the frequency of the support section and the number of affected subnetwork systems from high to low, and different priorities are distinguished according to the importance of the different-cable same-route hidden danger. In this way, the same-cable same-route and the different-cable same-route of the single or large-batch or single transmission subnetwork system can be distinguished according to the frequency of the optical cable in different transmission subnetwork systems and the frequency of the support section in different transmission subnetwork systems and the order from high to low of the influence range.

[0115] To make the detection method of the same-route hidden danger in the transmission network provided by the embodiments of the present disclosure clearer, the following embodiments are combined for description. Specifically, the detection method of the same-route hidden danger in the transmission network provided by the embodiments of the present disclosure includes the following three key technologies:

[0116] Key Technology 1: Quickly obtain the distribution of all optical cables used in the entire system.

[0117] Before introducing the detailed analysis methods, the fields to be used will be explained as follows:

[0118] Subnet System Name: To identify different subnets, each transmission subnet has a unique system name on the transmission network management system of different types (PTN / SPN / OTN / SDH, etc.) and different equipment manufacturers (Huawei, ZTE, Fiberhome, Bell, etc.) (e.g., XX-XX-First Trunk / Second Trunk / Core / Aggregation / Access-PTN / SPN / OTN / SDH Ring / System / Subnet-Serial Number).

[0119] Transmission segment name: The logical connection between different devices within a single transmission subnet system on the network management system can be described using the source and destination transmission device names and network port names (A-end device name - port name - Z-end device name - port name). This set of descriptions is the transmission segment name.

[0120] The name of the optical cable traversed: The specific optical path scheme describes the list of optical cables actually used in the transmission segment. If the transmission segment actually uses only one direct optical cable, then this field contains only one optical cable name. If the actual optical path corresponding to the transmission segment passes through one or more jump points such as optical cross-connectors, other equipment rooms, etc., and is connected end-to-end by multiple different optical cables, then this field contains a set of optical cable names.

[0121] Through the optical path scheduling process in routine network additions, cutovers, and adjustments, it is possible to not only clearly identify which transmission subnet system a single transmission segment belongs to and which logical link it is used for, but also accurately determine the names of all optical cables it traverses (this information can be obtained from the pipeline resource system). Therefore, a two-dimensional list can be designed to store the basic data, and the frequency of all optical cables can be statistically analyzed using the `collection.counter` container method. Using each optical cable as an index, the basic data is traversed to obtain the accurate association between optical cable, system, and transmission segment. This ultimately yields the specific name of each optical cable, its usage frequency, and the specific subnet systems and transmission segments in which it is distributed, as shown in Table 1.

[0122] Key Technology 2: Method for identifying potential hazards associated with co-cable and co-route connections.

[0123] Based on the distribution analysis results of all optical cables used in the entire system:

[0124] (1) If the same optical cable is used twice or more in the same subnet system, it can be determined that there is a hidden danger of the same cable and same route in a single subnet system that would cause the system to be interrupted in both directions.

[0125] (2)For the same cable in the network in multiple sub-network systems exist frequency greater than or equal to two times, can be determined as the same cable same route hidden danger will lead to batch system in two directions interruption.

[0126] (3)Statistical sorting of all the same cable same route hidden danger will lead to system in two directions interruption of sub-network system number and its in the corresponding sub-network system inside the number (must greater than or equal to 2), complete the whole network same cable same route hidden danger mining.

[0127] As an example, the distribution of the whole amount of optical cable in the whole amount of system can be shown in Table 2.

[0128] Table 2

[0129]

[0130] Key technology three: different cable same route hidden danger mining method

[0131] The idea of different cable same route hidden danger mining is to compare whether there is the same support section between different optical cables. A brief description is as follows: a complete optical cable is composed of one or more cable sections (cable section is the cable between one optical distribution frame ODF and the next optical distribution frame ODF, including optical distribution frame ODF, optical exchange, optical distribution, joint box, etc.), and the bottom layer of the cable section is one or more support sections (support section is a measure to support / protect the optical cable, including pipeline section, pole section, direct buried section, wall hanging section, lead-in section, etc.). Therefore, when two different optical cables use the same pipeline in a certain section, if the two cables are used in the main and standby two directions of the same transmission sub-network system, the system has different cable same route in the pipeline section. Once the pipeline is damaged due to excavation, there is a possibility that two optical cables are interrupted at the same time and the transmission sub-network system is interrupted in two directions.

[0132] When a new optical cable is entered into the pipeline resource system, the binding of the optical cable and the cable section, the cable section and the support section will be completed. Combined with the association relationship of optical cable-system-transmission section obtained in "key technology one", the whole process mapping of support section-optical cable-transmission section-system can be realized, as shown in Table 3. Then, the statistical sorting function of the collection.counter container method is used for the whole amount of support section frequency of system networking to identify different cable same route hidden danger:

[0133] (1)For the same support section in the same sub-network system with a frequency greater than or equal to two times, it can be determined that there is a different cable same route hidden danger in a single sub-network system that will lead to the interruption of the system in two directions.

[0134] (2)For the same support section in multiple sub-network systems in the network with a frequency greater than or equal to two times, it can be determined that there is a different cable same route hidden danger that will lead to the interruption of batch systems in two directions at the same time.

[0135] Statistical sorting of all heterogeneous cable same route risks can cause the number of subnets in both directions of the system interruption and its occurrence in the corresponding subnet system (must be greater than or equal to 2), complete the whole network heterogeneous cable same route risk mining.

[0136] Table 3

[0137]

[0138] According to the above three key technologies, the method provided by the disclosure implements the following steps:

[0139] Step S1: using System_Name, Transmission_Segment_Name, Cables_Name three one-dimensional lists, that is, the first list, the second list, and the third list, respectively reading all transmission segment names and their belonging subnet system names, and the list of optical cables (Cables_Name) passed through in sequence, and constructing a two-dimensional list Together with the association set of the three list single elements as elements:

[0140] Together[i]=[System_Name[i],Transmission_Segment_Name[i],Cables_Name[i]](i:0~whole network transmission segment number-1)

[0141] Step S2: disassemble the optical cable list string in each Cables_Name, obtain multiple single optical cable names, and store them in the list Cable_List in the form of elements, and do not remove the same optical cable name elements; apply the collection.counter container to Cable_List to count the frequency of different optical cables, and sort the optical cable frequency from high to low to obtain a dictionary structure Frequency_Cable, the Key value of the dictionary is the optical cable name, and the Value value is the optical cable frequency, and then call the most_common function to return the list Frequency_Cable_List composed of all (Key, Value) groups.

[0142] Step S3: To store the distribution of all optical cables used for networking on the whole quantum network system, define a two-dimensional list Cable_Distribution, that is, the fourth list; first traverse the two-dimensional list Together with the single optical cable name in Frequency_Cable_List[j][1] (j: 0 ~ total number of optical cables used for networking - 1) as the index, judge whether the optical cable name corresponding to Frequency_Cable_List[j][1] exists in Together[i][2]. When the match is successful, Frequency_Cable_List[j][1] optical cable name, Frequency_Cable[j][0] optical cable frequency, the corresponding subnet system name Together[i][0] and the transmission segment name Together[i][1] are constructed into a list, and the list is written into Cable_Distribution. After the traversal is completed, Cable_Distribution stores all optical cables used for system networking, and different subnet systems and transmission segments using the optical cables, and the distribution of the optical cables on the whole network system is obtained.

[0143] Step S4: Take the result Cable_Distribution of step S3 as the basis data set, use integer variable n1 to count the number of transmission segments in the same subnet system corresponding to the same optical cable, and use integer variable n2 to count the number of subnet systems affected by the same optical cable, the initial values of n1 and n2 are both 0, traverse Cable_Distribution, for a single optical cable in a subnet system, when n1 completes the statistical count and n1≥2, the number of subnet systems affected by the optical cable n2=n2+1. When the optical cable frequency≥2 and the number of subnet systems affected n2≥2 are true at the same time, the same cable and same route hidden danger that will cause batch system interruption in both directions is dug out; when the optical cable frequency≥2 and the number of subnet systems affected 0<n2<2 are true at the same time, the same cable and same route hidden danger that will only cause single system interruption in both directions is dug out; the screening result is still displayed in order from high to low according to the optical cable usage frequency and the number of affected subnet systems, and different priorities are distinguished for the importance of the same cable and same route hidden danger.

[0144] Step S5: Considering that the data volume of the whole network support section can reach millions, it is necessary to use pandas or database to process the data to ensure analysis efficiency. According to the correspondence between the optical cable and the optical cable section, the optical cable section and the support section, a two-dimensional list Cable_Support with each element as [optical cable name, support section name] is obtained. Cable_Distribution in step S3 stores the distribution of the whole optical cable in the whole network system. Traverse Cable_Support[n][0] (n: 0~total number of support sections-1) one by one with Cable_Distribution[m][0] (m: 0~total number of optical cables used in system networking-1) optical cable name as index. On the basis of obtaining the original system and transmission section information of each optical cable, the support section information of the optical cable is obtained, and the reverse mapping is performed to obtain the optical cable, system, etc. information supported by each support section, that is, [support section name, optical cable name, system name, transmission section name] (the same support section name can correspond to multiple optical cable names), which is used as an element to be added to the Support_Cable_System_List two-dimensional list, that is, the sixth list.

[0145] Step S6: The frequency of different support sections is sorted using the collection.counter container. After being converted to a list using most_common, the corresponding optical cable, subnetwork system, and transmission section information are associated to obtain the use distribution of the support section in the whole quantum network system: the two-dimensional subtable Support_Distribution.

[0146] Step S7: Based on the result Support_Distribution of step S6 as the basic data set, the integer variable N1 is used to count the number of transmission sections in the same subnetwork system corresponding to the same support section, and the integer variable N2 is used to count the number of subnetwork systems affected by the same support section. The initial values of N1 and N2 are both 0. Traverse Support_Distribution. For a single subnetwork system of a single support section, when N1 completes the statistical count and N1≥2, the number of subnetwork systems affected by the support section N2=N2+1. When the support section frequency≥2 and the number of subnetwork systems affected N2≥2 are both true, the hidden danger of different cables and the same route that can cause batch system interruption in both directions is found out. When the support section frequency≥2 and the number of subnetwork systems affected by the support section 0

[0147] Step S8: Save the data results and complete the hidden danger mining of the same cable and the same route and the different cable and the same route in the whole network.

[0148] It can be seen that the method provided by the present disclosure can mine the same route hidden danger of the transmission system based on full networking and pipeline data; the frequency statistics and sorting of different transmission optical cables in different transmission subnetwork systems and the frequency statistics and sorting of different optical cable support sections in different transmission subnetwork systems can be performed based on the collection.counter container method; the distribution of the optical cables and support sections used for networking in the full network in the full transmission subnetwork system is analyzed; and the full-range mapping association of the support section-optical cable-transmission section-system is realized. Based on this, on the one hand, the embodiment of the present disclosure can realize a full-amount same route analysis method. For example, the key field data can be stored by using a two-dimensional list or other data structure and matched and associated forward and backward according to relevant features, so as to realize the full-range mapping of the support section-optical cable-transmission section-system in the full network; the frequency of the optical cable in different transmission subnetwork systems and the frequency of the support section in different transmission subnetwork systems are counted by using the collection.counter container method, and the influence is ranked from high to low, so as to realize the full mining of the single full-amount / batch / single transmission subnetwork system same cable same route and different cable same route with differentiated priority. On the other hand, the efficient mining of the full hidden danger can be realized. For example, the collection.counter container method can be used. The counter is suitable for scenarios that need to quickly count the number of elements. The counting process only needs to be traversed once, which is fast and simple. Based on the obtained multiple-use association relationship of the support section-optical cable-transmission section-system in the full network, the collection.counter container method is used, which is more efficient.

[0149] The specific implementation and technical effects of each step of the embodiment are similar to those of the above-mentioned method embodiment, and will not be described here.
