[0033] In the above operating environment, the embodiment of the present application provides an optical link optimization method. Figure 2 FIG. 1 is a schematic diagram of a method flow for optimizing an optical link according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0034] Step S202: Acquire instance information corresponding to the optical network and determine vulnerable routing segments in the optical network based on the instance information. The instance information is used to characterize the topological connection structure of the optical network. A vulnerable routing segment includes a routing segment in which different links between two nodes in the optical network share the same optical cable segment.

[0035] Step S204: When either end of the vulnerable routing segment is connected to an optical fiber distribution frame device, a first type routing segment is determined in the optical network from the optical cable end in the first computer room to the opposite end, wherein the first computer room is the computer room corresponding to the vulnerable routing segment;

[0036] Step S206, determining a second type of routing segment in the optical network from the optical cable end to the opposite end in the second computer room, wherein the second computer room is another computer room belonging to the same station as the first computer room;

[0037] Step S208: Determine a target link optimization solution based on routing information corresponding to the first type routing segment and / or the second type routing segment, wherein the routing information is used to characterize the connection status of the first type routing segment and / or the second type routing segment in the optical network.

[0038] The target link optimization solution 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, combining the current status of the optical cable network to analyze the route, the route analysis scope is expanded to the local direction to which the optical path belongs, and the recommended results of the potential danger optical path are comprehensively evaluated and compared with the original optical path, the purpose of improving the efficiency and accuracy of optical link optimization is achieved, thereby solving the inefficient and unreliable technical problems caused by the fact that related technologies rely solely on manual verification of route security to make 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 Schematic diagram of a method flow for recommending a telecommunications cable hidden danger optimization solution according to an embodiment of the present application. 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 cable hazards existing in the optical path, including but not limited to: relay cable hazards, trunk 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 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 analyzed first, and N optimization methods can be formed (each optimization method corresponds to a first-class routing segment), that is, determining the first-class routing segment in the optical network from the optical cable termination facility in the first computer room to the opposite end. 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 of 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, 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, and the GJ node is the second node mentioned above. For the hidden danger routing segment shown by the red line segment in the figure, the analysis shows that its corresponding first routing segment includes different routes of the same cable node in the machine room corresponding to ① in the figure.

[0047] After that, we can continue to analyze the possibility of the optical cable reaching all subsequent nodes in the link and all terminated optical cable facilities at the opposite end, that is, determine the second routing segment. 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 also includes the following steps: determining a subsequent node corresponding to the hidden danger routing segment, wherein the subsequent node is a node passed through in the service link corresponding to the hidden danger routing segment, starting from the second node to the target node of the service link; determining the 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 hidden danger routing segment.

[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 the figure are the candidate nodes mentioned above, and the subsequent nodes of the same cable in the machine room and the different routes shown in ② and ③ are the second routing segment corresponding to the hidden danger routing segment.

[0050] After analyzing the optical cables in the same computer room (i.e., the first computer room corresponding to the potential risk 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 computer room belongs can be determined (the remaining computer rooms that belong to the same bureau as the first computer room, i.e., the second computer room) can be determined, and the possibility of optical cable routing from the bureau-to-optical cable termination facility to the opposite end can be further analyzed, i.e., the second-class routing segment from the optical cable termination facility in the second computer room to the opposite end in the optical network can be 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 end of the second computer room to the opposite end includes the following steps: determining the third routing segment between the node corresponding to the second computer room and the second node in the optical network, wherein the third routing segment is a routing segment in the optical network used to connect the node corresponding to the second computer room and the second node, and does not share the same section of optical cable with the hidden danger routing segment; determining the fourth routing segment between the node corresponding to the second computer room and the subsequent node in the optical network, wherein the fourth routing segment is a routing segment in the optical network used to connect the node corresponding to the second computer room and the subsequent node, and does not share the same section of optical cable with the hidden danger routing segment.

[0052] Specifically, the recommendation is made for the node routes with the same optical cable segment in the optical cable access link of the station, and the possibility of recommending all subsequent nodes in the optical cable access link and all terminated optical cable facilities in the opposite station direction is further considered. That is, firstly, the different routes (i.e., the third route segment mentioned above) (M1) from other optical cables in the same station direction to the optical nodes with the same optical cable segment in the optical path are analyzed. For example, Figure 4 As shown in the figure, 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 the different routes (i.e. the fourth route segment) (M2) from the same local optical cable to all subsequent optical nodes in the optical path with the same optical cable segment. For example, Figure 4 The different routes of subsequent nodes of the same cable in the stations corresponding to ⑤ and ⑥ are the fourth routing segment corresponding to the hidden danger routing segment.

[0054] After analyzing the optical cables in the same direction (i.e., the second computer room corresponding to the hidden 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 hidden dangers. The two-same comparison method is used to sort and push them according to safety factors such as the same pipeline segment in the entire link and the number of 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 the target link optimization scheme based on the routing information corresponding to the first type of routing segment and / or the second type of routing segment includes the following steps: generating a set of candidate schemes based on the routing information, wherein the candidate scheme set includes at least one candidate link optimization scheme, and each candidate link optimization scheme corresponds to a service transmission link from the start node to the target node composed of the first type of routing segment and / or the second type of routing segment; determining the number of hidden dangers between the service transmission link corresponding to each candidate link optimization scheme and the protection link corresponding to the 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 shaft; determining the candidate link optimization scheme with the least number of hidden dangers in the candidate scheme set 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. Based on 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 can be compared and analyzed to ultimately 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 potential danger routing segment, the method also includes the following steps: when both ends of the potential danger 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 potential danger routing segment in the optical network; determining a third type of 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 of routing segment, wherein the third type of 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 potential danger 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 solution takes the optical cable segments, pipeline segments, and optical nodes involved in the link as the minimum 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 end, 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 and pipeline networks of existing telecommunications networks for routing analysis. It is not limited to regional pipeline network data, and comprehensively analyzes optical routing elements such as the local direction, computer room, optical path, local fiber, optical cable segment, and pipeline segment. The local fiber and optical nodes 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 local direction to which the optical path belongs, making the analysis more comprehensive and the optimization plan more complete and practical. Furthermore, an effective evaluation method is used to compare the recommended route segment with the full main optical link route to ensure the optimization effect.
