The control device 13 may access the output result calculated and analyzed by the server through the ethernet, or may indirectly control the network device to be configured (for example, a switch device in a specific implementation) through the access router. The control device 13 and the network device 11 to be configured further include an access router 14, the access router 14 is directly connected to the network device 11 to be configured, and is connected and communicated with the switch control serial port through the management server, so that the function of remotely configuring port information can be realized. Therefore, the control device can indirectly and remotely read and write device information, verify configuration test and the like on the network device to be configured through the Ethernet.

The network topology scheme stored in the database mainly has two sources, namely a universal topology scheme is respectively manually introduced, and the universal topology scheme meeting most functional requirements is artificially designed and updated and synchronized into the network topology scheme database; in addition, a topology scheme is collected for the market environment, the topology scheme with stable market is synchronously updated through the Ethernet, network topology scheme items in the database are increased, and the functional coverage of the network topology scheme database is improved. The database comprises a large amount of scheme item information, wherein the scheme items mainly comprise information such as a topology scheme realization function, material requirements, physical topology, a port configuration command, a verification test script and the like, and scheme matching is carried out according to functional parameter information input by automatic configuration software. As shown in table 1, which is a possible illustration of the network topology stored in the database, each row represents a network topology, each network topology is numbered:
TABLE 1
Wherein, the numbering means that each row represents a network topology scheme, and each network topology scheme is marked by a numbering; the function refers to a function realized by a network topology scheme; the board card refers to the type of the board card adopted for realizing the function of corresponding numbering; the software version refers to the software version adopted for realizing the function with the corresponding number; the port number refers to the maximum port number of the board card capable of providing the support function; the material is the type of material required for realizing the function of corresponding numbering; the number of the chassis refers to the number of the chassis which can realize the function of corresponding numbering and at least needs to be satisfied: for example, it is necessary to implement a VSU (Virtual Switching Unit) function, establish n VSL (Virtual Switching Link) ports, and at least 2 chassis are required; the requirement port type is the requirement port type for realizing the network topology scheme with corresponding number; the configuration command refers to a configuration command of a correspondingly numbered network topology scheme.

Based on the application scenario shown in fig. 1, an embodiment of the present invention provides a network device configuration method, as shown in fig. 2, which is an implementation flow diagram of the network device configuration method provided in the embodiment of the present invention, and the implementation flow diagram may include the following steps:
and S21, receiving a network topology scheme matching request sent by the control equipment.
The topology scheme matching request carries network equipment configuration information, wherein the network configuration information comprises network equipment environment information, function information to be realized and material preparation information, and the network equipment environment information comprises first port information.
When the method is specifically implemented, the Python automation configuration software installed in the control equipment can acquire the network equipment environment information through the command script, the network equipment environment information can be used as an actual resource table, and the actual resource table mainly comprises the following steps: the device model, the board card information, the port information, the environment configuration information and the like.
In order to improve the matching quality of the topology scheme, in the embodiment of the invention, a user can also input the function information and the material preparation information which need to be realized through automatic configuration software, and the information of the functions, the software boundary conditions, the external components of the switch equipment and the like which are required to be realized by the configuration environment is used as the limiting parameters in the subsequent topology scheme matching process. For example, the information entered by the user through the automated configuration software is as follows:
1. the functions are as follows: establishing IP addresses of 10 different network segments (1.1.1.1-1.1.10.1/24);
2. materials: 10 AOC lines of 10G;
3. software boundary: soft1/soft2/soft3 … …;
4. board card: 24GT24SPF4XS-AC
5. The equipment model is as follows: S1/S2/S3.
Therefore, the functional information to be realized is IP addresses for establishing 10 different network segments, and the material preparation information is 10 AOC (active optical cable) lines.
After the control device obtains the network device configuration information, it sends a network topology scheme matching request to the server, where the network topology scheme matching request carries the obtained network device configuration information.
And S22, matching a candidate topology scheme in a pre-stored network topology scheme according to the function information to be realized and the network equipment environment information, wherein the candidate topology scheme comprises material requirement information and second port information.
In the embodiment of the invention, the topological scheme matching algorithm realizes the sufficient conditions and the necessary conditions based on the environment function, classifies the matching parameters, performs the matching analysis of the sufficient condition parameters on the premise of meeting the necessary conditions, and calculates the matching association degree of each topological scheme.
In specific implementation, the implementation function and the card transaction type can be used as necessary conditions, and the number of cases, the types of the demand ports and the like can be used as sufficient conditions to be matched in a pre-stored network topology scheme.
Taking the network topology scheme shown in table 1 as an example, first matching is performed in the network topology scheme according to the necessary conditions, that is, the function information to be implemented and the board type are necessary conditions. In this example, the functions to be implemented are to establish IP addresses of 10 different network segments, and the board card type is 24GT24SPF4 XS-AC. Accordingly, the candidate topology schemes numbered 1,2,3 and 4 can be matched in table 1.
And S23, for each matched candidate topology scheme, matching the material preparation information and the material demand information to obtain a first matching result and matching each port parameter contained in the first port information and the second port information to obtain a second matching result.
S24, determining a weight value corresponding to the candidate topology scheme according to the first matching result, the second matching result and the weight configured for the material information and each port parameter in advance.
In step S24, the weight value corresponding to each candidate topology may be determined according to the following formula:
wherein:
αwif the material preparation information is matched with the material demand information, alpha is the weighted value corresponding to the material informationwThe value is a preset weighted value, if the material preparation information is not matched with the material demand information, alpha iswThe value is 0;
n is the number of port parameters contained in the first port information or the second port information;
αnif the nth port parameter in the first port information is matched with the nth port parameter in the second port information, alpha is the weighted value corresponding to the nth port parameternThe value is a preset weight value, if the nth port parameter and the second port parameter in the first port informationIf the nth port parameter in the port information does not match, then alphanThe value is 0;
βwthe weight value is pre-allocated to the material information;
βnand assigning a weight value for the nth port parameter in advance.
Assume that the weight value configured for the port number is 30%, the weight value configured for the material information is 60%, and the weight value configured for the demand port type is 80%.
For the selected candidate topology 1, the corresponding weight value is (0.3+0+0)/(0.3+0.6+0.8) ═ 0.17
For the selected candidate topology scheme 2, the corresponding weight values are: (0.3+0+0)/(0.3+0.6+0.8) ═ 0.17
For the selected candidate topology scheme 3, the corresponding weight values are: (0+0.6+0.8)/(0.3+0.6+0.8) ═ 0.82
For the selected candidate topology 4, the corresponding weight values are: (0+0+0)/(0.3+0.6+0.8) ═ 0
And S25, determining the candidate topological scheme with the largest weight value as the optimal topological scheme.
According to the calculation result of step S24, it can be determined that the candidate topological scheme 3 is the optimal topological scheme.
And the server returns the determined optimal topology scheme to the control equipment, so that the control equipment carries out network equipment configuration according to the optimal topology scheme. Specifically, for the successfully matched port, the corresponding configuration command in the optimal topology scheme is executed. For the port with unsuccessful matching, the equivalent port function table needs to be called to search for the alternative. The first port information includes a required port type and cable resources, for example, for the above example, the number of ports in the determined optimal network topology scheme fails to match with the cable resources, and therefore, an equivalent alternative scheme needs to be searched.
In specific implementation, before executing step S25, the method for configuring a network device according to the embodiment of the present invention may further include the following steps: calling an equivalent port function table aiming at port parameters which are contained in second port information and are not matched in the candidate topology scheme with the largest weight value, and matching the candidate equivalent port scheme in the equivalent port function table according to the type of the required port, the port and the cable resource; for each matched candidate equivalent port scheme, determining a weight value of the candidate equivalent port scheme according to a weight configured for unmatched port parameters in advance; and determining the candidate equivalent port scheme with the maximum weight value as the optimal equivalent port alternative scheme.
Specifically, as shown in table 2, it is an illustration of a pre-stored equivalent port function table:
TABLE 2
Wherein, the numbering means that each row represents an equivalent port alternative, and each equivalent alternative is marked by a number; function refers to a function that an alternative implements; the board card type refers to the board card type adopted by the alternative scheme; the original demand port type is the demand port type which is firstly matched with the requirement; cable resources refer to implementation alternatives, cable resource requirements; replacing the demand port type means implementing an alternative, replacing the demand port type; configuration commands refer to alternative configuration commands.
In specific implementation, the necessary conditions for matching are the type of the original demand port and the cable resource, and candidate equivalent port schemes can be matched, and further, further matching is performed according to the board card type, the alternative demand port type, the port number and the like under sufficient conditions, assuming that the weight values corresponding to the board card type, the alternative demand port type and the port number are respectively 80%, 50% and 60%, respectively, calculating the weight value corresponding to each candidate equivalent port scheme, wherein the specific calculation method is the same as the calculation method for calculating the weight value corresponding to each candidate topology scheme, and details are omitted here. As can be seen from the calculation, the weight value corresponding to the candidate equivalent port scheme 1 is the largest, so that a gigabit optical port can be used to replace a gigabit optical port, and a corresponding configuration command is obtained and issued to the control device, and is issued by the control device to the network device to be configured for execution.
In specific implementation, the equivalent port function table may be manually subjected to statistical recording and imported into the database, and the equivalent port function table is mainly used for classifying the board card port information based on the implementation function, wherein the port information includes a required port type, a port rate, a port external device and the like.
And according to the optimal network topology scheme determined in the step S25, modifying the optimal network topology scheme by combining the equivalent substitute port information to obtain a final network topology map.
In specific implementation, the configuration may be performed by acquiring 10 corresponding tera ports according to the read network device environment information, for example, if it is determined that there are 3 pieces of 24GT24SPF4XS-AC according to the read network device environment information.
In the network configuration method, the device and the medium provided by the embodiment of the invention, the network topology scheme is pre-stored at the network side, so that when the network equipment configuration is needed, a network topology scheme matching request is sent to the network side through the control equipment, wherein the network topology scheme matching request carries network equipment configuration information, the network side matches the candidate topology scheme according to function information to be realized and network equipment environment information in the network equipment configuration information, material preparation information and material demand information in the candidate topology scheme and each port parameter contained in the first port information and the second port information are matched, and a weight value corresponding to the candidate topology scheme is determined according to a matching result and a weight pre-configured for the material information and each port parameter, so that an optimal topology scheme is selected, and the process does not need manual participation, so that the efficiency of the network equipment configuration is improved, the error probability of manual configuration is reduced, and the accuracy of network equipment configuration is improved.
