[0002] After decades of transmission network construction, the overall transmission network has become more complete and mature. The focus of the transmission network has shifted from construction to maintenance. As the cornerstone of market business development, the security and reliability of the transmission network play a vital role in business development. In the current 5G industry context, various government and enterprise businesses are increasing exponentially, and customers have higher requirements for business reliability, security, and low latency. Among them, the Optical Transport Network (OTN) is the backbone transmission network between provinces and cities. The impact range after a failure is huge, so the security risks of OTN networking are particularly prominent.

[0003] There are certain hidden dangers in the physical layer co-routing of OTN networking. Currently, the only way to deal with the hidden dangers of the physical layer co-routing of OTN networking is to rely on daily inspections by maintenance personnel. The main problems and shortcomings of inspections by maintenance personnel are as follows: (1) Due to the long link span between OTN network elements, the diverse physical line laying (such as overhead, pipeline, direct burial, wall hanging, etc.), and the frequent changes of maintenance personnel, the results of discovering co-routing hidden dangers through manual inspections are very limited; (2) The OTN network structure is complex, and maintenance personnel often cannot understand the actual networking scenario and cannot conduct targeted co-routing hidden danger inspections.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The terms "first", "second", etc. in the present invention are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein.

[0026] Combine the following Figure 1-Figure 7 The present invention describes an OTN subnet same-route analysis method, device, electronic device and storage medium.

[0027] It should be noted that the OTN subnet co-routing analysis method provided in the embodiment of the present invention is implemented based on the OTN subnet co-routing analysis device. OTN networking has an optoelectronic hybrid networking scenario, in which some OTN network element connections are carried by optical paths, and some OTN network element connections are carried by other OTN circuits, and the networking structure is complex. The OTN subnet co-routing analysis method provided by the present invention analyzes the network topology structure of the OTN subnet, establishes the association between the topological connection between network elements in the OTN subnet and the physical layer optical cable and the data carried by the optical cable, analyzes whether there are co-routing risks inside the OTN subnet, and solves the problem that the current co-routing risks of optoelectronic hybrid OTN subnets can only be analyzed manually, so that the network subnet structure can be optimized and adjusted for the physical co-routing part, and the physical co-routing safety risks can be eliminated to ensure the smooth and safe operation of the network.

[0028] The embodiment of the present invention describes the OTN subnet same-route analysis method by taking an OTN subnet same-route analysis device as an execution subject as an example.

[0029] Combination Figure 1 , Figure 1This is one of the flow charts of the OTN subnet same-route analysis method provided by the present invention. Figure 2 This is the second flow chart of the OTN subnet same-route analysis method provided by the present invention.

[0030] like Figure 1 As shown, the method includes the following: Step 101: Obtain the network topology structure of the optical transport network OTN subnet; Step 102: based on the network topology structure, grouping network elements having a topological connection relationship in the OTN subnet to obtain a plurality of topology groups; Step 103, matching the optical cable segment, bearing segment and bearing point associated with each topology group; Step 104: Perform a co-routing analysis based on the optical cable segments, bearer segments, and bearer points associated with each topology group to obtain a co-routing analysis result within the OTN subnet.

[0031] Figure 2 Each process of the entire OTN subnet routing analysis method is described in the following. Therefore, the following description of each process of the OTN subnet routing analysis method can be compared with Figure 2 To understand.

[0032] Specifically, firstly, an OTN subnet that needs to be subjected to same-route analysis is determined, and a network topology structure of the OTN subnet is obtained. Through the network topology structure of the OTN subnet, network element data contained in the OTN subnet can be obtained.

[0033] It should be noted that the network topology of the OTN subnet refers to the layout of each network element and its connection method in the OTN subnet. Common topologies include star, ring, mesh and tree, which determine how data flows in the network, how to achieve redundancy and load balancing, etc. Network elements are the basic components of the network, such as routers, switches, fiber switches and other devices. Each network element is responsible for a specific function, such as data forwarding, signal amplification or routing control, and the overall collaboration realizes network connection and data transmission. Therefore, through the network topology of the OTN subnet, the topological connection between network elements can be analyzed.

[0034] Furthermore, the topological connection relationship between network elements in the OTN subnet is parsed based on the network topology structure, and the network elements with topological connection relationship in the ONT subnet are grouped according to the topological connection relationship between the network elements to obtain multiple topological groups.

[0035] It should be noted that since the OTN subnet has the resource relationship of "optical path-optical cable segment-bearing segment-bearing point", these resource relationships usually have a specific hierarchical order, from larger network structures to more specific components. Therefore, the upper-layer resources can be further associated with the lower-layer resources.

[0036] Therefore, further, for each topology group, the associated optical cable segment is matched first, and then the associated bearing segment is matched based on the optical cable segment, and then the associated bearing point is matched based on the bearing segment. Finally, the optical cable segment, bearing segment and bearing point associated with each topology group can be matched.

[0037] Furthermore, a same-route analysis is performed based on the optical cable segments, bearer segments and bearer points associated with each topology group to obtain a same-route analysis result within the OTN subnet.

[0038] Furthermore, the same-route analysis results within the OTN subnet are visualized.

[0039] Furthermore, maintenance personnel optimize and adjust the network structure for the physical routing part based on the visualization results to eliminate the security risks of physical routing.

[0040] The OTN subnet co-routing analysis method provided by the present invention first groups network elements with topological connection relationships in the OTN subnet through the network topological structure of the OTN subnet, simplifies complex network connection relationships into multiple easy-to-manage topological groups, reduces the complexity of data processing and analysis, can effectively and accurately match the optical cable segment, bearing segment and bearing point associated with each topological group, further performs co-routing analysis based on the optical cable segment, bearing segment and bearing point associated with each topological group, obtains the co-routing analysis result in the OTN subnet, significantly improves the efficiency of the OTN subnet co-routing analysis, can timely discover and eliminate the existing network co-routing hidden dangers, thereby improving the security and reliability of transmission network networking.

[0041] In some embodiments, based on the network topology structure described in step 102, the network elements having a topological connection relationship in the OTN subnet are grouped to obtain multiple topology groups, and the specific process includes the following steps: Filtering out the internal component topological connections of each network element in the network topological structure to obtain the topological connection relationship between the network elements; Based on the topological connection relationship between the network elements, two network elements having a direct connection relationship are divided into one group to obtain multiple topological groups.

[0042] Specifically, the network topology structure of the acquired OTN subnet is used to filter out the internal component topology connection of each network element, and obtain the topology connection relationship between the network elements.

[0043] Among them, the internal component topology connection can be considered as the internal topology connection of the network element, such as the topology connection between internal components of the network element; the topology connection relationship between network elements can be considered as the external topology connection of the network element, such as the topology connection between two different network elements.

[0044] Furthermore, based on the topological connection relationship between network elements, two network elements having a direct connection relationship are divided into one group to obtain multiple topological groups.

[0045] It should be noted that two network elements with a direct connection relationship indicate that there is no other network element between the two network elements. In addition, there may be multiple topological relationships between two network elements with a direct connection relationship, which may be generated due to different links. Therefore, even if there are multiple topological relationships between the two network elements, the two network elements are divided into one group, not multiple groups.

[0046] In one embodiment, referring to Figure 3 , Figure 3 Schematic diagram of the OTN subnet topology grouping provided by the present invention. The OTN subnet includes network element A, network element B, network element C, network element D, network element E and network element F, wherein a straight line represents the topological connection relationship between two network elements. Figure 3 It can be seen that network element A and network element B are divided into topology group 1, network element B and network element C are divided into topology group 2, network element C and network element D are divided into topology group 3, network element D and network element E are divided into topology group 4, network element E and network element F are divided into topology group 5, and network element F and network element A are divided into topology group 6.

[0047] The embodiment of the present invention filters out the internal component topological connections of each network element, obtains the topological connection relationship between network elements, and further classifies the directly connected network elements into the same topological group. It can clearly divide multiple topological groups, effectively simplify the analysis of the network structure, improve the management efficiency of the topological group, and ensure the accuracy of the same routing risk analysis.

[0048] In some embodiments, based on step 103, when the optical cable segments, bearing segments, and bearing points associated with each topology group are matched, the following steps are performed for each topology group: Based on the topological connection relationship of the topological group, obtaining the topological A port and the topological Z port of the topological group; Based on the topology A port and the topology Z port of the topology group, matching the optical path associated with the topology group; If the optical path is matched, then the optical path route associated with the optical path is matched; Matching the optical cable segments associated with the optical path routing to obtain the optical cable segments associated with the topology group; The bearing segment associated with the optical cable segment and the bearing point within the bearing segment are matched to obtain the bearing segment and the bearing point associated with the topology group.

[0049] Specifically, based on the topological connection relationship of the current topological group, the topological A port and the topological Z port of the topological group are obtained, which can be considered as the input node and output node of the topological group. These ports identify the paths for data inflow and outflow, which are very important for network routing and performance analysis. By defining these ports, the transmission path of the network can be effectively managed and optimized to ensure efficient transmission of data in the network.

[0050] Further, based on the topology A port and the topology Z port of the topology group, the optical path associated with the topology group is matched.

[0051] In one case, if a lightpath is matched, the lightpath route associated with the lightpath is matched.

[0052] Furthermore, by matching the associated optical cable segments through optical path routing, the optical cable segments associated with the topological group are obtained, such as the direct buried segment, the pole segment, the pipeline segment, the wall-mounted segment, the lead-up segment, and the like.

[0053] Furthermore, the bearer segment associated with the topology group is obtained by matching the optical cable segment with the bearer segment associated with it.

[0054] Furthermore, by matching the associated bearing points of the bearing segments, the bearing points associated with the topology are obtained, such as manholes, point poles, hanging walls, marker stones, and guide rails.

[0055] In another case, if no optical path is matched, the data matching of the topology group is abandoned.

[0056] The embodiment of the present invention matches optical paths, optical cable segments, bearer segments and bearer points in sequence through resource relationships from top to bottom. This hierarchical matching method ensures accurate identification of resources at each level, and then performs co-routing analysis based on the matched optical cable segments, bearer segments and bearer points, thereby realizing automated co-routing analysis and timely determining co-routing risks. This solves the problem of currently relying on manual analysis of co-routing risks of optoelectronic hybrid OTN subnets, and improves the accuracy and efficiency of analyzing co-routing risks.

[0057] In some embodiments, the above process, based on the topology A port and the topology Z port of the topology group, matches the optical path associated with the topology group, and the specific process includes the following steps: Matching a circuit associated with the topology group based on a topology A port and a topology Z port of the topology group; If the circuit is matched, then the circuit route associated with the circuit is matched; Acquire a network element topology connection associated with the circuit route to obtain a network element set; Obtaining a topology A port and a topology Z port of the network element set; Matching the optical path associated with the topology group based on the topology A port and the topology Z port of the network element set; If the circuit cannot be matched, the optical path associated with the topology group is matched based on the topology A port and the topology Z port of the topology group.

[0058] Specifically, through the topology A port and the topology Z port of the topology group, the service equipment ports at both ends of the circuit A and Z are matched positively and negatively to obtain the circuit associated with the topology group, which is generally an OTN transmission circuit.

[0059] In one case, if an associated circuit is matched, the associated circuit is routed through the circuit match.

[0060] Furthermore, a network element topology connection associated with the circuit route is obtained to obtain a network element set.

[0061] Furthermore, a topology A port and a topology Z port of the network element set are obtained.

[0062] Furthermore, based on the topology A port and topology Z port of the network element set, the device ports at both ends of the optical path A and Z are matched forward and reversely to obtain the optical path associated with the topology group. This situation can be applicable to the scenario where there is a hybrid optoelectronic network in the OTN network, where some OTN network elements are connected through optical paths, and some OTN network elements are connected through other OTN circuits.

[0063] In another case, if no circuit is matched, the device ports at both ends of the optical path A and Z are matched forward and reversely based on the topology A port and the topology Z port of the topology group to obtain the optical path associated with the topology group.

[0064] In one embodiment, reference may be made to Figure 4 and Figure 5 , Figure 4 is a schematic diagram of the hierarchical relationship of topologically associated optical paths provided by the present invention, Figure 5 It is a schematic diagram of the hierarchical relationship of the topologically associated circuit provided by the present invention. Figure 4 When the connection between OTN network elements is carried by optical paths, the topology group is first matched to the associated optical path, then the optical path is matched to the associated optical cable segment, further the optical cable segment is matched to the associated bearer segment, and finally the bearer segment is matched to the associated bearer point. Figure 5 In the case of connecting other OTN circuits between OTN network elements, the associated circuits are first matched through the topology group, and then matched to the associated optical paths through the circuit routes corresponding to the circuits, and then matched to the associated optical cable segments through the optical paths, and then matched to the associated bearer segments through the optical cable segments, and finally matched to the associated bearer points through the bearer segments.

[0065] The embodiment of the present invention ensures the correct association and mapping of optical paths and circuits in the optoelectronic hybrid OTN network environment by first matching the circuit and then matching the optical path, thereby achieving a comprehensive analysis of complex routes and connections in the optoelectronic hybrid OTN network environment, and improving the accuracy of subsequent matching of corresponding optical cable segments, bearing segments and bearing points, thereby improving the accuracy of analyzing the hidden dangers of the same route.

[0066] In some embodiments, based on the same-route analysis based on the optical cable segment, bearer segment, and bearer point associated with each topology group described in step 104, the same-route analysis result in the OTN subnet is obtained, and the specific process includes the following steps: Multiple topology groups are grouped in pairs to obtain multiple same-route analysis groups; Performing co-routing analysis on the optical cable segments, bearer segments and bearer points associated with the two topological groups in each co-routing analysis group, and obtaining co-routing analysis results for each co-routing analysis group; The same-route analysis results of each same-route analysis group are integrated into the same-route analysis results within the OTN subnet.

[0067] Specifically, multiple topological groups are grouped in pairs to obtain multiple same-route analysis groups. For example, if there are N topological groups, C (N, 2) same-route analysis groups can be obtained after grouping in pairs.

[0068] Furthermore, the optical cable segments, bearer segments and bearer points associated with the two topological groups in each same-route analysis group are subjected to same-route analysis to obtain the same-route analysis results of each same-route analysis group.

[0069] In one case, if the same-route analysis results of each same-route analysis group are that there is no same-route, that is, there is no same-route in the optical cable segment, the same-route in the bearer segment, and the same-route in the bearer point, then it is determined that there is no same-route in the OTN subnet, and there will be no same-route risk, and there is no need to perform the next step of network optimization.

[0070] In another case, if the same-routing analysis result of any same-routing analysis group shows that there is same routing of the optical cable segment / same routing of the bearer segment / same routing of the bearer point, the same-routing analysis results of these same-routing analysis groups with the same routing are integrated into the same-routing analysis results within the OTN subnet.

[0071] The embodiment of the present invention ensures the feasibility and scientificity of the construction plan by performing a co-routing risk assessment before the construction of an OTN network or network cutover and adjustment. After the on-site construction is completed, the co-routing risk closed-loop verification is performed to timely discover and eliminate the network co-routing risks existing in the construction, thereby improving the security and reliability of the transmission network networking.

[0072] In some embodiments, in the above process, when performing the same-routing analysis on the optical cable segments, the bearer segments and the bearer points associated with the two topology groups in each same-routing analysis group to obtain the same-routing analysis results of each same-routing analysis group, the following steps are performed for each same-routing analysis group: Determine whether there is an overlapping portion between the optical cable segment associated with the first topology group and the optical cable segment associated with the second topology group; If there are cross-over and overlapped parts in the optical cable segments, determining the same-route analysis result of the same-route analysis group is that the same-route analysis group has the same-route of the optical cable segments; If there is no cross-overlapping portion in the optical cable segment, determining whether there is a cross-overlapping portion in the load-bearing segment associated with the first topology group and the load-bearing segment associated with the second topology group; If there are overlapping bearer segments, determining that the same-route analysis result of the same-route analysis group is that the same-route analysis group has the same bearer segment route; If the bearing segments do not have any overlapping parts, determining whether the bearing points associated with the first topology group and the bearing points associated with the second topology group have any overlapping parts; If there are overlapping bearer points, determining that the same-route analysis result of the same-route analysis group is that the same-route analysis group has the same bearer point route; If there is no overlapping part of the bearer points, it is determined that the same route analysis result of the same route analysis group is that the same route analysis group does not have the same route.

[0073] It should be noted that, in order to clearly describe the same-route analysis process of each same-route analysis group, the two topology groups in the same-route analysis group are described as a first topology group and a second topology group.

[0074] Specifically, it is determined whether there is an overlapping portion between the optical cable segment associated with the first topology group and the optical cable segment associated with the second topology group.

[0075] If there are cross-over and overlapping parts in the optical cable segments, the same-route analysis result of the same-route analysis group is determined to be that the same-route analysis group has the same-route of the optical cable segments.

[0076] If there is no cross-overlapping portion of the optical cable segment, it is determined whether there is a cross-overlapping portion of the load-bearing segment associated with the first topology group and the load-bearing segment associated with the second topology group.

[0077] If there are overlapping bearer segments, the same-route analysis result of the same-route analysis group is determined to be that the same-route analysis group has the same bearer segment route.

[0078] If the bearing segments do not have any overlapping parts, it is determined whether the bearing points associated with the first topology group and the bearing points associated with the second topology group have any overlapping parts.

[0079] If there are overlapping parts of the bearer points, the same route analysis result of the same route analysis group is determined to be that the same route analysis group has the same bearer point.

[0080] If there is no overlapping part of the bearer points, it is determined that the same route analysis result of the current same route analysis group is that the same route analysis group does not have the same route.

[0081] The embodiment of the present invention ensures the feasibility and scientificity of the construction plan by performing a co-routing risk assessment before the construction of an OTN network or network cutover and adjustment.
