BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 The present invention is a flowchart of a method for automatically activating an SPN data dedicated line service according to an embodiment of the present invention. DETAILED DESCRIPTION

[0030] Specifically, the process of the automatic activation method of SPN data dedicated line service in the embodiment of the present invention is as follows: Figure 1 As shown, it includes steps 101 to 105.

[0031] Step 101: Receive the SPN data line service work order in real time, where the service work order includes: service scenario, service parameters, product type, customer service level, service bandwidth, service guarantee level, A-end access address, Z-end access address, required nodes, and customer code;

[0032] Step 102: Allocate slices according to the product type; select the site closest to the A-end access address and the site closest to the Z-end access address; access the resources of each selected site, find the site with the most sufficient resources among the sites closest to the A-end access address as the A-end network element, and find the site with the most sufficient resources among the sites closest to the Z-end access address as the Z-end network element; select the idle device port of the A-end network element as the A-end port according to the type of allocated slices, and select the idle device port of the Z-end network element as the Z-end port; determine the shortest path from the A-end port to the Z-end port in the SPN network topology that passes through the necessary nodes; from the determined shortest paths, select the shortest path that meets the pre-set selection conditions as the optimal design solution;

[0033] Step 103: Allocate resources according to the optimal design solution, customer service level, service bandwidth, and service guarantee level, and generate network configuration data;

[0034] Step 104: Encapsulate the network configuration data, business scenarios and business parameters into configuration instructions, and call the transmission workbench to send the configuration instructions to the corresponding SPN network devices;

[0035] Step 105: Call the fault monitoring system to verify whether the configuration instruction is correctly issued; if yes, the activation is successful and the task is completed; if not, return to execute steps 102 to 105.

[0036] Among them, in step 101, the SPN data dedicated line service work order is received in real time, implemented using the RESTFUL interface based on the HTTP protocol, and nginx load balancing is used to handle high-concurrency requests to maintain efficient service.

[0037] In step 102, the selection conditions include: the shortest path and / or no repeated nodes and / or no loops.

[0038] In step 103, the configuration data includes circuit configuration data and circuit routing configuration data. The circuit data includes: circuit code, A-end computer room, A-end network element, A-end port, A-end VLAN, Z-end computer room, Z-end network element, Z-end port, Z-end VLAN, circuit bandwidth, protection mode, etc.; the circuit routing configuration data includes: routing type (primary, backup), routing segment sequence number, routing segment A-end network element and port information, routing segment Z-end network element and port information, etc.

[0039] Here, the configuration of VLAN resources is achieved by building a VLAN resource pool, specifically: managing idle and used VLANs at the three levels of network elements, ports, and VLANs to implement VLAN resource configuration.

[0040] In step 105, verify whether the configuration instruction is correctly issued, specifically: the alarm serial number, alarm title, alarm level, alarm occurrence time, alarm clearing time, network element name, positioning information, circuit number and network element information obtained by the fault monitoring system are compared to see whether the obtained network element name, positioning information, circuit number and network element information are consistent with the corresponding information in the configuration instruction. If they are consistent, it is considered to be correctly issued; otherwise, it is considered to have not been correctly issued.

[0041] In a possible implementation, in step 102, allocating slices includes:

[0042] The product type is the basic version - slice dedicated line, allocated shared large network slices; the product type is the advanced version - premium slice dedicated line, allocated exclusive slices for customers; the product type is the customized version - industry slice private network, allocated shared slices for customers.

[0043] Here, the product types are defined as basic version - dedicated slice line, advanced version - premium slice line, and customized version - industry slice private network, corresponding to shared large network slice, exclusive slice for customers, and shared slice for customers. Among them, shared large network slice and shared slice for customers use the Quality of Service (QoS) scheduling mechanism to complete the scheduling between different services within the slice, while exclusive slice for customers uses FGU small particle technology to further complete the strict hard isolation between different services within the slice.

[0044] In another possible implementation, in step 102, determining the shortest path includes:

[0045] Collect data sets to generate SPN network topology;

[0046] Arrange all the necessary nodes to generate a necessary node matrix M with n*(n-1) rows and n columns; take the first necessary node in each row of M as an element to form the starting matrix M1; take the last necessary node in each row of M as an element to form the end matrix Mn, and calculate the shortest path that passes through the necessary nodes in each row of the matrix M in sequence;

[0047] Calculate the shortest path from the A-end port to each necessary node in M1; calculate the shortest path from each necessary node in Mn to the Z-end port;

[0048] The shortest path from the A-port to each necessary node in M1, the shortest path that sequentially passes through the necessary nodes in each row of matrix M, and the shortest path from each necessary node in Mn to the Z-port are connected to obtain the determined shortest path.

[0049] Here, the shortest path from the A-port to each necessary node in M1, the shortest path sequentially passing through each row of the matrix M, and the shortest path from each necessary node in Mn to the Z-port are all calculated using the Dijkstra algorithm.

[0050] If the business work order also includes the unavoidable nodes, the unavoidable nodes are removed from the collected data set.

[0051] In another possible implementation, the better shortest paths can also be displayed to the user, and the user can select one of them as the optimal design solution. For example, the determined shortest paths are sorted from short to long, and the top five paths are displayed to the user, and the user can select one of the five paths as the optimal design solution.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
