Description

Technical Field

[0001] This invention relates to the field of communication service resource consumption analysis, and in particular to a method, system, and storage medium for analyzing common routing risks during critical periods of communication service protection. Background Technology

[0002] Shared routing risks (i.e., risks associated with shared trenches, cables, and systems) refer to situations in communication network reliability design where multiple service paths rely on the same physical or logical resource, leading to concentrated risks. These include:

[0003] Same trench: Different optical cable segments share the same conduit / pole (same physical path).

[0004] Same cable: Different optical paths share the same optical cable (same physical carrier).

[0005] Same system: Different services share the same transmission system multiplex segment (same logical path).

[0006] During critical telecommunications protection periods, it is necessary to avoid the occurrence of communication service circuits in the same trench, cable, and system, and to quickly analyze and calculate the resource usage of service circuits.

[0007] Traditional fault analysis focuses on which service circuits are affected by a fault in a single optical cable or transmission system. For example, the Beijing-Kowloon-Guangzhou optical cable, the Second Beijing-Shenyang-Harbin optical cable, and the Beijing-Tianjin-Nanjing-Shanghai optical cable are analyzed to determine which communication services will be affected by a fault.

[0008] The problem with the above method is:

[0009] Poor timeliness: When carrying out different critical protection tasks, it is necessary to find the underlying optical cable resources and analyze and judge the communication services that will be affected, which results in a lot of time being wasted on analyzing and querying each optical cable. Summary of the Invention

[0010] Purpose of the invention: To propose a method, system, and storage medium for analyzing common routing risks during critical periods of communication service protection, in order to solve the aforementioned problems existing in the prior art.

[0011] In a first aspect, the present invention proposes a method for analyzing common routing risks during critical periods of communication service protection, comprising the following steps:

[0012] S1. Select the potential hazard analysis method, including same route, near route, cross route, and same system;

[0013] S2. Select a reference object and an analysis object. The reference object can be one, and the analysis object can be one, multiple, or not selected.

[0014] S3. Based on the service type, query the relationship between professional trunks and transmission circuits. The service types include transmission, computer, and automatic telephone. Circuits that are not part of the transmission service need to be associated with transmission circuits before further analysis can be performed.

[0015] S4. Based on the resource occupancy relationship of the transmission circuit, recursively query the system route of the transmission circuit;

[0016] S5. Based on the resource occupancy relationship of the transmission circuit, recursively query the medium route of the transmission circuit;

[0017] S6. Based on the system routing of the transmission circuit, calculate whether there are any hidden dangers in the same system between the reference object and the analysis object;

[0018] S7. Based on the medium routing of the transmission circuit, calculate whether there are potential risks of the reference object and the analysis object sharing the same trench, cable, or cross routing.

[0019] In a further embodiment of the first aspect, in step S1, the definition of the hazard analysis method is as follows:

[0020] Same route: The medium route of the service is the same cable but different fiber cores, the same fiber core but different systems, or the same system but different ports, and the medium routes occupied by different services are in the same optical cable segment;

[0021] Nearest route: The calculated distance between the marker points under the optical cable segment of the medium route where different cable services are located is ≤10 meters;

[0022] Cross-route: The media routes of the service are intersected at the same local exchange.

[0023] Same system: The system route of the service is a multiplexed segment within the same system, but located in different channels or time slots.

[0024] In a further embodiment of the first aspect, in step S2, when one or more analysis objects are selected, the reference object is compared with each analysis object to determine whether there is a common routing risk; when no analysis object is selected, the entire network service circuit is compared with the reference object to determine whether there is a common routing risk.

[0025] In a further embodiment of the first aspect, in step S3, if the non-transmission circuit is not associated with the transmission circuit, the user is prompted that a common routing vulnerability analysis cannot be performed.

[0026] In a further embodiment of the first aspect, in step S4, the recursive query rule for the system routing is as follows: calculate the resource system occupied by each circuit segment, wherein the resource system includes optical cable, leased optical fiber, OLP, OCP, wavelength division multiplexing, TMUX, SDH, PDH, channel, and relay resources; obtain the transmission system channel or time slot information occupied by each circuit segment through a recursive algorithm; and concatenate them in the order of the circuit segments in the format of "station A < occupied C&S system name>station B < occupied C&S system name>...station Z".

[0027] In a further embodiment of the first aspect, in step S5, the recursive query rule for the medium routing is as follows: calculate the resource system occupied by each circuit segment, the resource system including optical cable, leased fiber, OLP, OCP, wavelength division multiplexing, TMUX, SDH, PDH, channel, and relay resources, obtain the optical cable core information occupied by each circuit segment through a recursive algorithm, and concatenate them in the order of the circuit segments in the format of "station A《optical cable name + / + core symbol (F) + core number》station B".

[0028] In a further embodiment of the first aspect, in step S6, the calculation method for the system-wide hidden danger is as follows: query the transmission system multiplexing segment to which it belongs through the channel / time slot. If the reference object and the analysis object occupy the same two stations of the transmission system multiplexing segment, it is determined that there is a system-wide hidden danger.

[0029] In a further embodiment of the first aspect, in step S7, the calculation method for the potential risks of co-cable, co-channel, and cross-routes is as follows:

[0030] Same cable: The reference object and the analysis object occupy the same optical cable segment at both ends of the local stations;

[0031] Same trench: The reference object and the analysis object occupy different local stations at both ends of the optical cable segment, and the latitude and longitude distance between any two marker points under the marker segment of the optical cable segment is ≤10 meters;

[0032] Cross-routing: The optical cable segment occupied by the reference object and the analysis object references the same identifier point and is located in the same station.

[0033] A second aspect of the present invention provides a common route hazard analysis system during critical protection missions, the system comprising:

[0034] The resource model construction module is used to construct a resource model, which includes, from bottom to top, optical fiber, OLP, wavelength division, OCP, SDH system, PDH system, transmission circuit, and service trunk layer. Among them, service trunk and transmission circuit represent communication services, while optical fiber, OLP, wavelength division, OCP, SDH system, and PDH system represent services that use optical waves as the transmission medium.

[0035] The hazard analysis method selection module allows users to choose one of four hazard analysis methods: same route, near route, cross route, and same system.

[0036] The object selection module is used to select a reference object and an analysis object, wherein the reference object is one, and the analysis object is one, multiple, or not selected.

[0037] The association query module is used to query the association between professional trunks and transmission circuits based on the business type. The business types include transmission, computer, and automatic telephone. Circuits that are not part of the transmission profession need to establish an association with the transmission circuit before subsequent analysis can be performed.

[0038] The system routing recursive query module is used to recursively query the system routes of transmission circuits based on the resource occupancy relationship of the transmission circuits.

[0039] The media routing recursive query module is used to recursively query the media routing of the transmission circuit based on the resource occupancy relationship of the transmission circuit.

[0040] The hidden danger calculation module is used to calculate whether the reference object and the analysis object have hidden dangers in the same system, and to calculate whether the reference object and the analysis object have hidden dangers in the same trench, the same cable, or cross routes, based on the system routing of the transmission circuit.

[0041] A third aspect of the present invention provides a computer-readable storage medium storing at least one executable instruction that, when executed on an electronic device, causes the electronic device to perform the co-routing vulnerability analysis method during the critical period of communication service protection as described in the first aspect.

[0042] Compared to existing technologies, this application offers the following advantages: It enables a comprehensive analysis of resources occupied at the service circuit level, solving the problem of analyzing service circuits only for single optical cable resources. This allows for analysis at the service circuit level to determine if multiple service circuits share the same cable, network, or system, facilitating users in avoiding the use of service circuits in the same cable, network, or system during critical periods. If service circuits in the same cable, network, or system are found during critical periods, users can easily identify the optical cables or transmission system resources requiring priority protection, enabling them to quickly allocate maintenance resources and ensure communication during critical periods. Attached Figure Description

[0043] Figure 1 This is a schematic diagram of the resource model constructed in the embodiment.

[0044] Figure 2 This is a flowchart of the method for analyzing common routing risks during the critical period of communication service protection in the embodiment. Detailed Implementation

[0045] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0046] This application constructs a resource model, dividing it into multiple business layers from bottom to top, such as... Figure 1 As shown, this includes: optical fiber cables, OLP, wavelength division multiplexing (WDM), OCP, SDH systems, PDH systems, transmission circuits, and service trunks. Service trunks and transmission circuits are communication services, while optical fiber cables and other services use light waves as the transmission medium.

[0047] Figure 2 This demonstrates the workflow for analyzing common routing risks during critical periods of communication service protection. The steps are as follows:

[0048] S110: Select the potential hazard analysis method, which includes four methods: same route, near route, cross route, and same system.

[0049] Same route: The service is located on the same cable but different fiber cores, different systems on the same fiber core, or different ports on the same system. Different services occupy the same optical cable segment.

[0050] Nearest route: The intermediate route of a service is calculated by identifying the marker point under the optical cable segment of the intermediate route of different cable services. If the distance is less than or equal to 10 meters, it is considered a near route.

[0051] Cross-route: Routes that cross within the same local station and are used for the same service are considered cross-route.

[0052] Same system: The system routing of the service is the same system multiplex segment, but different channels or time slots.

[0053] S120: Select a reference object and analyze the object.

[0054] One reference object can be selected, while multiple analysis objects can be selected, or none can be selected. When one or more analysis objects are selected, the reference object is compared with multiple analysis objects to identify potential risks associated with shared trenches, cables, and systems. When no analysis objects are selected, the entire network's service circuits are analyzed and compared with the reference objects to identify potential risks associated with shared trenches, cables, and systems.

[0055] S130: Based on the service type, query the relationship between professional trunks and transmission circuits.

[0056] The service type can be selected from professional fields such as transmission, computer, and automatic telephone. Circuits not belonging to the transmission field need to establish a relationship with the transmission circuit before analysis of whether they are in the same trench, cable, and system can be performed. If the circuits not belonging to the transmission field are not established a relationship with the transmission circuit, the user will be prompted that analysis of whether they are in the same trench, cable, and system cannot be performed.

[0057] S140: Based on the resource occupancy relationship of the transmission circuit, recursively query the system route of the transmission circuit.

[0058] S150: Based on the resource occupancy relationship of the transmission circuit, recursively query the medium route of the transmission circuit.

[0059] S160: Based on the transmission circuit system routing, calculate whether the reference object and comparison object are multiplexed sections in the same system.

[0060] The transmission system channel and time slot information occupied by the transmission circuit are calculated according to the routing calculation rules. The transmission system multiplexing section to which the channel / time slot belongs is determined by querying the channel / time slot, and the two ends of the multiplexing section are checked for consistency. If the two ends of the multiplexing section occupied by the analyzed object are the same, it is determined to be in the same transmission system. The system route of the transmission circuit can be obtained by occupying S140.

[0061] S170: Based on the transmission circuit medium route, calculate the reference object and compare whether the objects are in the same trench, on the same cable, or cross the route.

[0062] The fiber optic core information occupied by the transmission circuit is calculated according to the routing calculation rules. The fiber optic segment to which the core belongs is queried using the core information, and it is calculated whether the two ends of the fiber optic segment are the same. The system route of the transmission circuit can be obtained from S150.

[0063] If the optical cable segment occupied by the object being analyzed is the same at both ends of the local station, it is determined to be the same cable.

[0064] The objects being analyzed occupy different stations at both ends of the optical cable segment. By querying the identification segment information under the optical cable segment, the latitude and longitude of the identification points at both ends of the identification segment are compared. If the latitude and longitude distance between any two identification points in the identification segment is less than 10 meters, it is judged to be in the same trench; if the identification segments refer to the same identification point, it is judged to be cross-routes.

[0065] The routing calculation rules are as follows:

[0066] System routing: Calculate the resource system occupied by each circuit segment. Since the resource types that a circuit segment can occupy include optical cable, leased fiber, OLP, OCP, wavelength division multiplexing, TMUX, SDH, PDH, channel, and trunk resources, each layer of resource occupancy has resource occupancy relationships. The transmission system channel or time slot information occupied by each circuit segment is calculated through a recursive algorithm. The transmission system information occupied by the circuit is concatenated in the order of the circuit segments, and the concatenation is performed in the following format: Station A "Occupied C&S System Name" Station B "Occupied C&S System Name" Station C "Occupied C&S System Name" Station Z.

[0067] Medium routing: Calculate the resource system occupied by each circuit segment. Since the resource types that a circuit segment can occupy include optical cable, leased fiber, OLP, OCP, wavelength division multiplexing, TMUX, SDH, PDH, channel, and trunk resources, each layer of resource occupancy has resource occupancy relationships. The optical cable core information occupied by each circuit segment is calculated through a recursive algorithm. The optical cable information occupied by the circuit is concatenated in the order of the circuit segments and assembled in the following format: Station A "Optical cable name + / + fiber core symbol (F) + fiber core number" Station B.

[0068] The specific application scenarios and execution steps of the above embodiments are as follows:

[0069] Step 1: When a major conference security mission is underway, the parameters of each transmission circuit are obtained from the outer layer to the inner layer based on the transmission circuit resources involved in the mission. The resource relationships occupied by each circuit are then recursively queried, for example, the transmission system resource information occupied by the transmission circuit.

[0070] Step 2: Recursively establish the relationship between all resource levels from the outer layer to the inner layer, such as the optical cable information occupied by the transmission system.

[0071] Step 3: Calculate the routing of the transmission circuit system. Based on the resource occupancy relationship, calculate whether the transmission systems occupied by the multiple transmission circuits involved in the critical protection task are the same transmission system or the same transmission system multiplexing segment.

[0072] Step 4: Calculate the transmission circuit medium routing. Based on the resource occupancy relationship and the relationship between optical cable segments and optical cable identification segments, calculate whether the optical cables occupied by the multiple transmission circuits involved in the critical protection task are in the same trench, on the same cable, or cross each other.
