[0001] This disclosure relates to the field of computer technology, specifically to a submarine cable cost calculation method, apparatus, electronic device, storage medium and computer program product. Background Art

[0002] Submarine cables are cables wrapped with insulating materials and laid on the seabed for communication transmission. As a key infrastructure for international information interconnection and energy transmission, submarine cables have high construction and operation costs and complex structures, involving multiple cost dimensions such as materials, laying, maintenance and operation management. Traditional cost accounting methods are difficult to accurately collect and allocate various costs to specific consumption objects, resulting in unclear cost sources, ambiguous expenditure purposes, and difficulties in benefit assessment, which cannot provide effective data support for product pricing, resource optimization and strategic decision-making. Clear product cost estimation is the foundation of a product benefit evaluation system. Traditional cost calculation methods struggle to clearly identify cost flows, leading to an inability to accurately assess product benefits. Therefore, a submarine cable cost estimation method is urgently needed to support product benefit evaluation and differentiated resource allocation, thereby improving the transparency and decision-making effectiveness of international submarine cable operation and management.

[0022] Figure 1 shows a flowchart of a submarine cable cost calculation method according to an embodiment of this disclosure. As shown in Figure 1, the submarine cable cost calculation method may include the following steps.

[0023] In step S110, at least one submarine cable route segment is obtained according to the submarine cable topology map; each submarine cable route segment includes two submarine cable nodes and one submarine cable channel.

[0024] In the embodiments of this disclosure, referring to the submarine cable line cost calculation schematic diagram shown in Figure 4, at least one submarine cable route segment to be calculated is identified and extracted according to the pre-constructed submarine cable network topology map. The submarine cable topology diagram reflects the physical or logical connection relationship of the submarine cable network, including all submarine cable nodes (such as landing stations, branch units, repeaters, etc.) and the submarine cable channel paths connecting these nodes.

[0025] In this embodiment of the disclosure, each submarine cable route segment is defined as a basic cost accounting unit, which structurally includes two submarine cable nodes (nodes A, B, and Z in Figure 4) and a submarine cable channel connecting the two nodes (channels 1 and 2 in Figure 4).

[0026] Specifically, a submarine cable node represents a physical site or equipment aggregation point geographically located in a specific country or region. It is the core location for generating localized costs (i.e., "point costs"), and its cost composition may include equipment depreciation, local leasing, operation and maintenance expenses, etc. A submarine cable channel represents a cross-border or cross-regional transmission segment between two nodes. It is the carrier for generating transmission process costs (i.e., "line costs"), and the costs may include submarine cable depreciation, cross-border circuit leasing, channel maintenance, etc. By parsing the routing segments of these "node 1-channel-node 2" structures from the topology, the system lays the structural foundation for subsequent cost collection and allocation according to the "two-point-one-line" model. This step realizes the decomposition of the complex submarine cable network into standardized minimum cost calculation units.

[0027] In step S120, the unit capacity cost of the submarine cable node is obtained. Specification 3 / 11 page 6 CN 121213121 A

[0028] In this embodiment of the disclosure, based on the Activity-Based Costing (ABC) principle and combined with the cost elements of the submarine cable (nodes and channels), a cost calculation method based on the "two-point-one-line" model is constructed.

[0029] In this embodiment of the disclosure, since the composition of submarine cable node cost and submarine cable channel cost are different, this disclosure determines the cost of submarine cable node and submarine cable channel separately. Meanwhile, since each submarine cable node is usually connected to multiple submarine cable channels, it is difficult to separate its cost in different submarine cable routing segments. Based on this, this disclosure proposes a capacity-based cost calculation method. The system obtains the node unit capacity cost of each submarine cable node. The node unit capacity cost refers to the cost allocated to the submarine cable node per unit capacity. The capacity of the submarine cable node refers to the total inlet and outlet capacity (bandwidth) of the node, regardless of the submarine cable routing segment to which the capacity belongs. The node unit capacity cost is a key indicator for measuring the cost allocated per unit throughput capacity of the submarine cable node.

[0030] In step S130, the channel unit capacity cost of the submarine cable channel is obtained.

[0031] In this embodiment of the disclosure, similar to the aforementioned node unit capacity cost, the channel unit capacity cost of the submarine cable channel corresponding to the submarine cable routing segment is obtained. The channel unit capacity cost refers to the cost allocated to the submarine cable channel per unit capacity. The capacity of the submarine cable channel refers to the transmission capacity (bandwidth) of the channel. The capacity of the submarine cable channel is also the capacity of the submarine cable route segment, that is, the data transmission capacity between the two submarine cable nodes, also known as line capacity. The cost per unit capacity of the channel is a key indicator for measuring the cost per unit throughput capacity of the submarine cable channel.

[0032] In step S140, the unit capacity cost of the route segment of the submarine cable is calculated based on the node unit capacity cost of the two submarine cable nodes and the channel unit capacity cost of the submarine cable channel.

[0033] In this embodiment of the present disclosure, the unit capacity cost of the route segment of the submarine cable is calculated based on the node unit capacity cost of the two submarine cable nodes corresponding to the submarine cable route segment and the channel unit capacity cost of the corresponding submarine cable channel. This step calculates the unit capacity cost of the submarine cable route segment based on the unit capacity cost of the two submarine cable nodes and the channel unit capacity cost of the corresponding submarine cable channel, using unit capacity as the unit. This method avoids the complexity of cost accounting caused by the different composition methods of submarine cable node costs and submarine cable channel costs, and effectively integrates the originally scattered node and channel costs into a unified cost indicator based on capacity. The resulting unit capacity cost of the routing segment can serve as a core input for downstream product cost splicing, resource benefit assessment, and differentiated pricing strategies, achieving precise penetration and quantitative management of costs to specific business objects and routes.

[0034] In an exemplary embodiment, the unit capacity cost of the two submarine cable nodes and the unit capacity cost of the submarine cable channel are summed to obtain the unit capacity cost of the routing segment. Taking the embodiment shown in Figure 4 as an example, the unit capacity cost of the routing segment = unit capacity cost of node A + unit capacity cost of the submarine cable channel + unit capacity cost of node B. This superposition method has a clear physical meaning: the unit cost of a complete routing segment consists of the processing cost of the starting node, the channel transmission cost, and the cost of the channel transmission cost.The cost and the processing cost of the termination node together constitute the cost.

[0035] In step S150, the routing segment cost of the submarine cable route segment is calculated based on the unit capacity cost of the routing segment and the bandwidth corresponding to the submarine cable route segment.

[0036] In this embodiment of the present disclosure, the routing segment cost of the submarine cable route segment is calculated based on the unit capacity cost of the routing segment calculated above and the bandwidth corresponding to the submarine cable route segment. That is, the routing segment cost = unit capacity cost of the routing segment × bandwidth. Wherein, the unit capacity cost of the routing segment (yuan / Gbps) represents the comprehensive cost carried by each unit capacity transmitted on the routing segment, while the bandwidth (Gbps) represents the capacity occupied by the submarine cable route segment. The bandwidth usually corresponds to the capacity of the submarine cable channel.

[0037] As mentioned above, the submarine cable route segment is the basic cost accounting unit of the submarine cable topology. Based on the routing segment cost of each submarine cable route segment, the cost of the target submarine cable line or submarine cable network can be further calculated, but the further calculation process will not be described here. The submarine cable line is a communication line composed of multiple submarine cable route segments connected end to end. The submarine cable network specification 4 / 11 page 7 CN 121213121 A is a communication network composed of multiple submarine cable route segments interconnected.

[0038] The submarine cable cost calculation method provided in this embodiment of the present disclosure obtains at least one submarine cable route segment according to the submarine cable topology map; obtains the node unit capacity cost of the submarine cable node; obtains the channel unit capacity cost of the submarine cable channel; calculates the route segment unit capacity cost of the submarine cable route segment according to the node unit capacity cost and the channel unit capacity cost; calculates the route segment cost of the submarine cable route segment according to the route segment unit capacity cost and the bandwidth corresponding to the submarine cable route segment. This method avoids the complexity of cost accounting caused by the different composition methods of submarine cable node cost and submarine cable channel cost, and effectively integrates the originally scattered node and channel costs into a unified cost index based on capacity, realizing accurate penetration and quantitative management of cost to specific business objects and routes.

[0039] Figure 2 shows a flowchart of the node unit capacity cost calculation method of this embodiment of the present disclosure. In this embodiment of the disclosure, based on the submarine cable cost calculation method shown in Figure 1, step S120 may include the following steps.

[0040] In step S210, the node cost of the submarine cable node is obtained.

[0041] In this embodiment of the disclosure, the node cost of the specified submarine cable node must first be obtained. The node cost refers to the total cost related to the submarine cable node. Since there are multiple cost accounting methods, this disclosure does not limit the cost accounting methods it has. The focus of this disclosure is to allocate the obtained total node cost to the unit capacity, and to integrate it with the channel cost based on capacity.

[0042] In an exemplary embodiment, the node cost can cover multiple dimensions such as equipment, resources, facilities and services.Depreciation. Specifically, it may include: depreciation of various local equipment (such as transmission equipment), depreciation of locally built submarine cables and IRU (irrevocable right of use) resources, depreciation of pipelines and optical cables; amortization of assets related to infrastructure, such as amortization of the right of use assets of POP point equipment rooms and IDC equipment rooms; continuous operating expenses, such as rental fees and electricity costs of POP / IDC equipment rooms; and various maintenance and rental costs incurred to ensure stable network operation, such as transmission equipment maintenance fees, maintenance costs of locally built submarine cables and IRUs, trunk circuit rental costs, equipment rental fees, service outsourcing fees, and even building wiring costs. The above cost items are only used to illustrate the cost calculation composition of submarine cable nodes and are not used to limit the specific accounting method of the node cost.

[0043] In step S220, the node ingress and egress capacity of the submarine cable node is obtained.

[0044] In this embodiment of the present disclosure, the node ingress and egress capacity of the specified submarine cable node is obtained. The node ingress and egress capacity is not a single link capacity, but an aggregation of the total ingress and egress communication resources belonging to the node. It reflects the overall capacity and import / export bandwidth capabilities of the submarine cable node in the network.

[0045] In an exemplary embodiment, the import / export capacity of the node can cover submarine cable capacity, IRU capacity, trunk circuit capacity, cross-border circuit capacity, etc. Specifically, it can include: the self-built submarine cable capacity used as input / output by the node, the purchased IRU (irrevocable right of use) capacity, the leased trunk circuit capacity, and other cross-border circuit capacity. All these capacity data are measured and summed in a unified unit (such as Gbps).

[0046] In step S230, the node unit capacity cost is calculated based on the node cost and the node import / export capacity.

[0047] In this embodiment of the present disclosure, the node unit capacity cost of the submarine cable node is calculated based on the total node cost and the total node export capacity obtained in the preceding steps, so that the cost of the submarine cable node is allocated in units of capacity. Specifically, node unit capacity cost = node cost / total node export capacity.

[0048] Through the above method, the complex multi-dimensional cost pool is aggregated into an intuitive unit cost indicator in units of capacity. This indicator not only quantifies the average cost burden borne by each unit of import / export capacity provided by a node, but more importantly, it provides a unified cost indicator for the assembly of unit costs of downstream routing segments. It is the basis for achieving accurate penetration and splicing calculation of costs along the physical route.

[0049] Figure 3 shows a flowchart of the channel unit capacity cost calculation method according to an embodiment of this disclosure. In this embodiment of the disclosure, based on the submarine cable cost calculation method shown in Figure 1, step S130 may include the following steps.

[0050] In step S310, the channel cost of the submarine cable channel is obtained.

[0051] In this embodiment of the disclosure, the channel cost of the specified submarine cable channel needs to be obtained first. The channel cost refers to the total cost related to the submarine cable channel. Since there are multiple ways to calculate costs, this disclosure does not limit the specific cost calculation method. The core of this disclosure is to standardize and allocate the total channel cost based on the obtained cost per unit capacity so that it can be integrated with the node cost for calculation based on the same unit.

[0052] In an exemplary embodiment, the channel cost mainly covers various expenses incurred during cross-border transmission, including but not limited to: depreciation of self-built submarine cable segments, depreciation of IRU (Irrevocable Right of Use) resources, maintenance costs of self-built submarine cables and IRUs, relay circuit leasing costs, and cross-border circuit leasing costs, etc. The above cost items are used to illustrate the typical composition of submarine cable channel costs and are not a limitation on its calculation method.

[0053] In step S320, the channel transmission capacity of the submarine cable channel is obtained.

[0054] In this embodiment of the disclosure, the channel transmission capacity of the specified submarine cable channel needs to be obtained. This capacity represents the total data transmission capacity that the channel can carry and is the key denominator for calculating the unit cost.

[0055] In an exemplary embodiment, the channel transmission capacity is the sum of the capacity of various transmission resources possessed by the channel itself, specifically including: the capacity of the self-built submarine cable, IRU capacity, relay circuit capacity, and cross-border circuit capacity corresponding to the channel. All these capacity data are measured in a unified unit (such as Gbps) and summarized into the total transmission capacity of the channel.

[0056] In step S330, the channel unit capacity cost is calculated based on the channel cost and channel transmission capacity.

[0057] In this embodiment of the present disclosure, based on the total channel cost and total channel transmission capacity obtained in the aforementioned steps, the unit capacity cost of the submarine cable channel is calculated, thereby realizing the allocation of the total channel cost to each unit of transmission capacity. The specific calculation formula is: channel unit capacity cost = channel cost / channel transmission capacity.

[0058] Through the above method, the complex costs of the cross-border transmission segment are aggregated into a standardized unit cost index. This indicator quantifies the average cost incurred by the channel for carrying one unit of capacity, providing a core input for assembling the unit cost of the complete route segment with the unit cost of the node, and is an important basis for achieving accurate end-to-end cost calculation.

[0059] As mentioned above, based on the route segment cost of each submarine cable route segment, the cost of the target submarine cable line or submarine cable network can be further calculated. Based on this, this disclosure further provides a method for calculating the cost of a submarine cable line based on the route segment cost.

[0060] Figure 4 shows a schematic diagram of the submarine cable line cost calculation according to an embodiment of this disclosure. As shown in Figure 4, the submarine cable topology diagram includes two submarine cable route segments (AB segment and BZ segment). Among them, the AB segment submarine cable route segment includes: A-end submarine cable node, submarine cable channel, etc.Channel 1 and B-end submarine cable node. The BZ segment submarine cable route includes: B-end submarine cable node, submarine cable channel 2 and Z-end submarine cable node. The AB segment submarine cable route and the BZ segment submarine cable route are connected end to end to form the submarine cable line AZ.

[0061] In some exemplary embodiments, the submarine cable line cost calculation method may include the following steps.

[0062] Obtain at least one first submarine cable route segment included in the submarine cable line; the at least one first submarine cable route segment is connected end to end to form the submarine cable line; calculate the line cost of the submarine cable line according to the route segment cost corresponding to each first submarine cable route segment.

[0063] In this embodiment of the present disclosure, multiple first submarine cable route segments included in the target submarine cable line are obtained according to the submarine cable topology map. The first submarine cable route segment can be any submarine cable route segment in the submarine cable topology map. The first submarine cable route segments are connected end to end to form the submarine cable line. As shown in Figure 4, the AB segment and the BZ segment of the submarine cable route are connected end to end to form the submarine cable line AZ.

[0064] In this embodiment of the present disclosure, the route segment cost corresponding to each first submarine cable route segment is calculated according to the aforementioned steps S110-S150. That is, the route segment cost (Cost_AB) of the AB segment and the route segment cost (Cost_BZ) of the BZ segment are calculated independently first. When calculating the cost of each route segment, the unit capacity cost of its corresponding route segment is multiplied by its actual occupied bandwidth.

[0065] Finally, the total line cost (Total_Cost_AZ) of the submarine cable line AZ is obtained by adding the costs of all its constituent route segments, that is: Total_Cost_AZ = Cost_AB + Cost_BZ. This method decomposes complex lines into standard routing segments for cost accounting, which not only achieves modularization and refinement of cost calculation, but also ensures that the cost can be accurately penetrated to the entire physical path, providing reliable data support for end-to-end product pricing, benefit assessment and resource optimization.

[0066] In some exemplary embodiments, the submarine cable line cost calculation method may include the following steps.

[0067] Obtain at least one second submarine cable routing segment included in the submarine cable line; the at least one second submarine cable routing segment is connected end to end to form the submarine cable line; calculate the line unit capacity cost of the submarine cable line according to the unit capacity cost of the routing segment corresponding to each second submarine cable routing segment; calculate the line cost of the submarine cable line according to the line unit capacity cost and the bandwidth corresponding to the submarine cable line.

[0068] In this embodiment of the present disclosure, multiple first submarine cable routing segments included in the target submarine cable line are obtained according to the submarine cable topology map. The first submarine cable routing segment can be any submarine cable routing segment in the submarine cable topology map. Each first submarine cable routing segment firstThe ends are connected to form a submarine cable line. As shown in Figure 4, the AB segment and the BZ segment of the submarine cable route are connected end to end to form the submarine cable line AZ.

[0069] In this embodiment of the present disclosure, the unit capacity cost of each route segment is calculated according to the aforementioned steps S110-S140, namely the unit capacity cost of the AB segment (Unit_Cost_AB) and the unit capacity cost of the BZ segment (Unit_Cost_BZ). After calculating the unit cost of each segment, the line unit capacity cost (Line_Unit_Cost_AZ) of the submarine cable line AZ is obtained by summing the unit costs of each component route segment, that is: Line_Unit_Cost_AZ = Unit_Cost_AB + Unit_Cost_BZ. This value represents the average cost that each unit capacity (Gbps) should be allocated on the entire line when the signal is transmitted from end A to end Z.

[0070] Finally, the total line cost (Total_Cost_AZ) of the submarine cable line AZ is obtained by multiplying its unit capacity cost by the total bandwidth (Bandwidth_AZ) actually configured or occupied by the line. The calculation formula is: Total_Cost_AZ = Line_Unit_Cost_AZ × Bandwidth_AZ. This method first integrates the cost of all routing segments at the unit capacity level, and then calculates the total cost based on the actual service usage, ensuring the accuracy and interpretability of end-to-end cost calculation, and providing accurate data basis for product pricing and investment decisions.

[0071] Figure 5 shows the model architecture diagram of submarine cable cost calculation according to an embodiment of this disclosure.

[0072] In some exemplary embodiments, the model architecture for submarine cable cost calculation can be built based on the Hadoop ecosystem. The model architecture may include the following parts.

[0073] 1. Data Acquisition Layer (Kafka + Sqoop)

[0074] Real-time Data Stream: Use Kafka to collect real-time streaming data such as submarine cable resource equipment information, operation and maintenance data, node and routing segment capacity utilization logs, etc., and write it to the Topic through the Producer API. The data is pre-processed by the collection (such as filtering invalid data and standardizing the format) and then transferred to the Consumer Group application tenant for subscription and use.

[0075] Batch Data Integration: Use Sqoop to periodically synchronize table data incrementally from relational databases (such as SAP system, BSS system, revenue collection system, new generation resource system, etc.) to HDFS, including: Network construction cost table (equipment investment depreciation, installation fees, etc.) Operation and maintenance cost table (maintenance contract fees, rental fees, etc.) Capacity configuration table (number of submarine cable physical ports, IRU capacity allocation, etc.) 2. Storage Layer (HDFS + TelePG)Raw data storage: The collected raw data is stored in HDFS in Parquet columnar format and organized according to the partitioning strategy to improve query efficiency.

[0076] Structured storage: TelePG (distributed database) is used to store the processed cost model result table, which supports high-concurrency visualization query.

[0077] point_cost (point cost table: country, cost item, total capacity, unit cost)

[0078] line_cost (line cost table: cross-border segment ID, AZ end country, line capacity, unit cost)

[0079] product_cost (product total cost table: routing path, product unit cost)

[0080] 3. Model capability layer

[0081] Through the above cost algorithm logic, a wide table model is built to collect point / line costs, which can briefly describe network construction costs and network operation and maintenance costs.

[0082] 1) Network construction costs (investment depreciation costs) can include: self-built submarine cable depreciation, IRU depreciation, POP points, data center usage rights assets, equipment depreciation, etc.

[0083] 2) Network operation and maintenance costs: Repair costs are refined using SAP's internal order numbers. Through BSS order numbers and procurement contracts in the resource system, a strong correlation between network operation costs and routing segments is achieved. Network operation costs are integrated and reimbursed through BSS management.

[0084] 4. Visualization Application Layer

[0085] TelePG hybrid storage architecture: Cold data is archived to HDFS, and hot data is retained in TelePG. A cost collection application table is constructed. Data is synchronized from the data middle platform HDFS to the TelePG relational database. Finally, data visualization is achieved through BI intelligent visualization tools.
