[0033] Under the above operating environment, the embodiment of the present application provides an optical link optimization method. Figure 2 is a schematic diagram of a method flow for optical link optimization provided according to an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0034] Step S202, obtaining instance information corresponding to the optical network, and determining a routing segment with hidden dangers in the optical network based on the instance information, wherein the instance information is used to characterize the topological connection structure of the optical network, and the routing segment with hidden dangers includes: a routing segment in which different links between two nodes in the optical network share the same section of optical cable;

[0035] Step S204, when any end of the vulnerable routing segment is connected to the optical fiber distribution frame device, determine the first type of routing segment in the optical network from the optical cable end of the first computer room to the opposite end, wherein the first computer room is the computer room corresponding to the vulnerable routing segment;

[0038] The target link optimization scheme is used to eliminate the same-cable hidden dangers existing in the hidden danger routing segment.

[0039] Through the above steps, by taking the local optical fibers and optical nodes involved in the optical path as analysis particles and analyzing the routes in combination with the current status of the optical cable network, the route analysis scope is expanded to the local direction to which the optical path belongs, and the recommended results of the optical path with hidden dangers are comprehensively evaluated and compared with the original optical path, the purpose of improving the optimization efficiency and accuracy of the optical link is achieved, thereby solving the inefficient and unreliable technical problems caused by the fact that the relevant technology relies solely on manual verification of route security for optimization recommendations in the face of massive existing network resources.

[0040] The optical link optimization method in steps S202 to S208 of the embodiment of the present application is further introduced below.

[0041] Figure 3 is a schematic diagram of a method flow recommended for optimizing a telecommunication cable risk according to an embodiment of the present application, such as Figure 3 shown.

[0042] First, establish a security link group service link instance, that is, obtain the instance information corresponding to the optical network, and determine all the same cable hazards in the optical path, including but not limited to: same relay optical cable hazards, trunk optical cable hazards, etc. The specific steps are as follows.

[0043] In some embodiments of the present application, different links between two nodes in an optical network include: a service link, and a protection link corresponding to the service link, wherein the service link is a service transmission link from a starting node to a target node; based on instance information, determining a potential danger routing segment in the optical network includes the following steps: when the service link and the protection link share the same section of optical cable, determining the routing segment in the optical network that shares the same section of optical cable as a potential danger routing segment, wherein the type of optical cable includes at least one of the following: a relay optical cable and a trunk optical cable.

[0044] After determining the hidden dangers in the same cable and the hidden danger routing segment in the optical network, the optical link node data can be first obtained from the instance information to determine whether there are ODF (Optical Distribution Frame) facilities at both ends of the hidden danger routing segment. If there are ODF facilities at either end, the possibility of optical cable routing from the optical cable termination facility in the computer room to the opposite end can be first analyzed to form N optimization methods (each optimization method corresponds to a first-class routing segment), that is, determining the first-class routing segment from the optical cable termination facility in the first computer room to the opposite end in the optical network. The specific steps are as follows.

[0045] In some embodiments of the present application, the first type of routing segment includes: a first routing segment; determining the first type of routing segment in the optical network from the optical cable end in the first computer room to the opposite end includes the following steps: determining the first node and the second node corresponding to the two ends of the potential danger routing segment in the optical network, respectively, wherein the first node corresponds to the first computer room; determining the first routing segment between the first node and the second node in the optical network based on instance information, wherein the first routing segment is a routing segment in the optical network used to connect the first node and the second node, and does not share the same optical cable segment with the potential danger routing segment.

[0046] Specifically, a recommendation is made for the node routes with the same optical cable segment in the optical cable access link of the computer room, that is, different routes (i.e., the first route segment) (N1) from the optical cable in the same computer room (i.e., the first computer room) to the optical node with the same optical cable segment in the optical path are determined. For example, Figure 4 As shown, the ODF node is the first node mentioned above, the GJ node is the second node mentioned above, and for the hidden danger routing segment shown by the red line segment in the figure, the analysis shows that the corresponding first routing segment includes different routes of the same cable node in the computer room corresponding to ① in the figure.

[0047] After that, the possibility of the optical cable reaching all subsequent nodes in the link and all terminated optical cable facilities at the opposite end can be further analyzed, that is, the second routing segment can be determined. The specific steps are as follows.

[0048] In some embodiments of the present application, the first type of routing segment also includes: a second routing segment; determining the first type of routing segment in the optical network from the optical cable termination in the first computer room to the opposite end direction also includes the following steps: determining a subsequent node corresponding to the routing segment with hidden dangers, wherein the subsequent node is a node passed through in the service link corresponding to the routing segment with hidden dangers, starting from the second node to the target node of the service link; determining a second routing segment between the first node and the subsequent node in the optical network based on instance information, wherein the second routing segment is a routing segment in the optical network used to connect the first node and the subsequent node, and does not share the same optical cable segment with the routing segment with hidden dangers.

[0049] Specifically, the different routes (i.e., the second route segment) (N2) from the optical cable in the same machine room (i.e., the first machine room) to all subsequent optical nodes in the optical path with the same optical cable segment are analyzed. For example, Figure 4 The two GF nodes in are the above-mentioned candidate nodes, wherein the subsequent nodes of the same cable in the machine room corresponding to ② and ③ shown in different routes are the second routing segment corresponding to the hidden danger routing segment.

[0050] After analyzing the optical cables in the same machine room (i.e. the first machine room corresponding to the potential danger routing segment), N optimization methods (N=N1+N2) can be formed, i.e. N first-class routing segments are determined. Then, the bureau to which the machine room belongs can be determined (the remaining machine rooms belonging to the same bureau as the first machine room, i.e. the second machine room, are determined). The possibility of optical cable routing from the bureau-direction optical cable termination facility to the opposite end is further analyzed, i.e. the second-class routing segment from the optical cable termination in the second machine room to the opposite end in the optical network is determined. The specific steps are as follows.

[0051] In some embodiments of the present application, the second type of routing segment includes: a third routing segment and a fourth routing segment; determining the second type of routing segment in the optical network from the optical cable termination to the opposite end direction in the second computer room includes the following steps: determining the third routing segment between the node corresponding to the second computer room in the optical network and the second node, wherein the third routing segment is a routing segment in the optical network used to connect the node corresponding to the second computer room with the second node, and does not share the same section of optical cable with the routing segment with hidden dangers; determining the fourth routing segment between the node corresponding to the second computer room in the optical network and the subsequent node, wherein the fourth routing segment is a routing segment in the optical network used to connect the node corresponding to the second computer room with the subsequent node, and does not share the same section of optical cable with the routing segment with hidden dangers.

[0052] Specifically, the node routes of the optical cable access link of the station are recommended, and the possibility of recommending all subsequent nodes in the optical cable access link and all terminated optical cable facilities in the opposite station is further considered, that is, firstly, the different routes of other optical cables in the same station to the optical nodes with the same optical cable segment in the optical path (that is, the third route segment mentioned above) (M1) are analyzed. For example, Figure 4 As shown, the computer room corresponding to the ODF node is the other computer room belonging to the same station as the ODF2 node, that is, the second computer room. Figure 4 The different routes of the same cable node in the station corresponding to ④ are the third routing segment corresponding to the hidden danger routing segment;

[0053] After that, we continue to analyze different routes from the same local optical cable to all subsequent optical nodes with the same optical cable segment in the optical path (i.e., the fourth route segment mentioned above) (M2), and give an example. Figure 4 The different routes of the subsequent nodes of the same cable in the stations corresponding to ⑤ and ⑥ are the fourth routing segment corresponding to the potential risk routing segment.

[0054] After analyzing the optical cables in the same direction (i.e., the second computer room corresponding to the potential danger routing segment), M optimization methods (M=M1+M2) can be formed, that is, M second-class routing segments are determined. Then, based on the routing information corresponding to the N+M first-class routing segments and / or second-class routing segments, multiple candidate link optimization schemes can be formed, and the candidate link optimization schemes and the original protection optical path routing are analyzed for potential dangers. The two-same comparison method is used to sort and push according to safety factors such as the same pipeline segment of the entire link and the number of front wells in the same bureau to determine the best recommended scheme. The specific steps are as follows.

[0055] In some embodiments of the present application, determining a target link optimization scheme based on routing information corresponding to a first-class routing segment and / or a second-class routing segment includes the following steps: generating a set of candidate schemes based on the routing information, wherein the set of candidate schemes includes at least one candidate link optimization scheme, and each candidate link optimization scheme corresponds to a service transmission link from a start node to a target node, which is composed of a first-class routing segment and / or a second-class routing segment; determining the number of hidden dangers between a service transmission link corresponding to each candidate link optimization scheme and a protection link corresponding to a hidden danger routing segment in the optical network, wherein the number of hidden dangers includes at least one of the following: the number of the same pipeline segments, the number of the same optical cable segments, and the number of the same bureau front wells; determining the candidate link optimization scheme with the least number of hidden dangers in the set of candidate schemes as the target link optimization scheme.

[0056] Specifically, the optical cable segments involved in the recommended optical cable and the main route optical path codes can be used as input parameters. According to the relationship between the optical path and the office optical fiber, the relationship between the office optical fiber and the optical cable segment, the relationship between the optical cable segment and the sub-pipe and pipeline segment, and the relationship between the pipeline segment and the facility, the routing safety factors such as the number of holes in the same pipeline segment and the same bureau front hole can be compared and analyzed to finally determine the optimization method. For example, the candidate link optimization schemes can be ranked according to the number of hidden dangers in the same pipeline segment and the same bureau front well, and the target link optimization scheme with the least hidden dangers can be determined.

[0057] On the other hand, when there are no ODF facilities at both ends of the vulnerable routing segment, the method also includes the following steps: when both ends of the vulnerable routing segment are not connected to the optical fiber distribution frame equipment, determining the first node and the second node corresponding to the two ends of the vulnerable routing segment in the optical network; determining a third-type routing segment from the first node or the second node to the opposite end in the optical network, and determining the target link optimization plan based on the routing information corresponding to the third-type routing segment, wherein the third-type routing segment is a routing segment in the optical network that is connected to the first node or the second node and does not share the same optical cable with the vulnerable routing segment.

[0058] The present application provides a link optimization solution for optimizing the safety hazards of dual links in optical networks in complex pipeline networks and optical cable network structures. The optical cable segments, pipeline segments, and optical nodes involved in the links are used as the smallest analysis particles. For hazards in the same optical cable segment, the analysis scope includes the direction to which the optical path belongs, establishes an association between the direction and the optical cable termination, expands the recommendation scope, searches for possible optical nodes for orderly analysis, and uses the method of comparative analysis of routes with hazards in the same pipeline to make an in-depth comparison of multiple routing solutions and make the best recommendation.

[0059] This application solution can be applied to the complex optical cable network and pipeline network of the existing telecommunications network for routing analysis. It is not limited to regional pipeline network data. It comprehensively analyzes the optical routing elements such as the office direction, machine room, optical path, office optical fiber, optical cable section, and pipeline section. The office optical fiber and optical node involved in the optical path are used as analysis particles. Combined with the current status of the optical cable network, the routing analysis scope is expanded to the office direction to which the optical path belongs, making the analysis more comprehensive and the optimization plan more complete and practical. In addition, an effective evaluation method is used to compare the recommended route section with the full main optical link route to ensure the optimization effect.
