Description
Technical Field
The invention relates to the field of telecommunication transmission network management, in particular to a field rule automatic generation system and a field rule automatic generation method.
Background
In the management of telecommunications transport networks, there is a need to manage various types of network elements and configuration data on a single disk. Each type of device file for a network element or single disk describes configuration data on the network element or single disk. In the management process, the network element configuration needs to be abstracted from the network manager to manage the configuration data on the network element and the single disk. The network element configuration and the configuration data both comprise a plurality of fields, the fields of the network element configuration can find corresponding fields in certain configuration data, and the rules (such as types, value ranges and the like) of the fields need to be known in the management process. The same network element configuration, the network elements or single disks of different types, the configuration data corresponding to the fields of different types, and the field rules of different types. Different fields may correspond to fields of different configuration data for the same network element configuration.
Because the field rule of the network element configuration is related to the specific configuration data of the network element or the single disc, the existing management method defines different network element configurations according to the types of different network elements and single discs, and the different network element configurations correspond to the specific configuration data one to one. This method has significant disadvantages: firstly, configuration data with the same function may be abstracted into different network element configurations only due to the difference of some fields, so that the network element configurations are redundant and not universal; secondly, there is no uniform field rule generation method, and when a new single disk, a new network element or new configuration data is added, the existing rule acquisition system needs to be modified, so that the stability and maintainability of the system are reduced.

Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
Example 1
Referring to fig. 1, embodiment 1 of the present invention provides an automatic field rule generation system, which includes a general model generation module, a default rule generation module, an equipment rule generation module, and a rule merging module.
The generic model generation module is to: and generating a general network element configuration and shielding the difference of configuration data between the equipment files. The general model generation module analyzes and arranges general network element configuration, namely a general model, from the configuration data of various equipment files, generates a field mapping table and stores the field corresponding relation between the general network element configuration and the configuration data of the equipment files.
The structure of the field mapping table is as follows: < general network element configuration field, network element type, single disc type, configuration data field >. The above structure represents: the fields in the general network element configuration can correspond to different configuration data fields according to the difference between the network element type and the single disc type.
The fields of the network element configuration are divided into simple fields and complex fields. A simple field refers to a field that is not subdividable, and a complex field refers to a field that is subdivided into multiple fields. The corresponding relation in the field mapping table must be that a simple field corresponds to a simple field, and a complex field corresponds to a complex field.
The default rule generation module is used for: and setting default field rules for the general network element configuration. It can be seen from the workflow of the generic model generation module that the fields of the generic network element configuration may not find the corresponding configuration data fields in certain types of network elements and single-disk device files. Therefore, it is necessary to preset default rules of fields of the general network element configuration to prevent the situation that the field rules cannot be found.
The device rule generation module is to: extracting field rules of configuration data related to network elements or single-disk types from the device file: < network element type, single disc type, configuration data field, device field rule >.
The rule merging module is used for: and aiming at certain type of network element configuration, combining the default field rule and the field rule of the equipment according to the network element and the single-disk type where the network element is located, and outputting a general field rule. This general field rule meets the following requirements: the same field can be provided with differentiated field rules according to specific network elements and single disc types; when the field rule of the equipment does not exist, a default field rule is used as supplement; the field rules are generated by a unified flow.
Example 2
Referring to fig. 2, embodiment 2 of the present invention provides an automatic field rule generation method, including the following steps:
s1, the general model generating module generates general network element configuration and shields the difference of configuration data between the device files. The general model generation module analyzes and arranges general network element configuration, namely a general model, from the configuration data of various equipment files, generates a field mapping table and stores the field corresponding relation between the general network element configuration and the configuration data of the equipment files.
The structure of the field mapping table is as follows: < general network element configuration field, network element type, single disc type, configuration data field >. The above structure represents: the fields in the general network element configuration can correspond to different configuration data fields according to the difference between the network element type and the single disc type.
The fields of the network element configuration are divided into simple fields and complex fields. A simple field refers to a field that is not subdividable, and a complex field refers to a field that is subdivided into multiple fields. The corresponding relation in the field mapping table must be that a simple field corresponds to a simple field, and a complex field corresponds to a complex field.
S2, the default rule generating module sets default field rule for the general network element configuration. It can be seen from the workflow of the generic model generation module that the fields of the generic network element configuration may not find the corresponding configuration data fields in certain types of network elements and single-disk device files. Therefore, it is necessary to preset default rules of fields of the general network element configuration to prevent the situation that the field rules cannot be found.
S3, the device rule generating module extracts the field rule of the configuration data related to the network element or the single disc type from the device file: < network element type, single disc type, configuration data field, device field rule >.
S4, the rule merging module merges the default field rule and the field rule of the device according to the network element and the single disc type of the network element configuration of a certain type, and outputs the universal field rule. This general field rule meets the following requirements: the same field can be provided with differentiated field rules according to specific network elements and single disc types; when the field rule of the equipment does not exist, a default field rule is used as supplement; the field rules are generated by a unified flow.
Example 3

compared with the XML of the network element type 1 and the single disk type 1, the same XML is the configuration data of the eth interface, and l3_ attr is added to the field; and l2_ attribute configuration data, fields are modified to svlanid and cvlanid.

S12, judging whether the device file is traversed or not, if yes, ending, otherwise, turning to the step S13. Which is equivalent to traversing the two XML files described above.
S13, judging whether the configuration data in the device file is traversed, if yes, returning to the step S12, and if not, going to the step S14. And 2 eth _ interface, 2 l2_ attribute and 1 l3_ attribute in the two XML files are traversed for a total of 5 configuration data.
S14, checking whether the type of the current configuration data exists in the set in S11, if yes, going to step S15, otherwise, returning to step S13. This is to check whether the configuration data in the two XML files are related to eth _ interface.

On the basis of embodiment 1 or 2, the default rule generating module has the input of the general network element configuration and the output of the default rule generating module is the default field rule < general network element configuration field, default field rule >, as shown in fig. 4, and the work flow thereof is as follows:
s21, define default rules for simple fields, go to step S22.
As described above, the general network element configuration XML uses two simple fields, WORD and STRING, and may define default rules WORD as r (w) < default ═ 0,' [0-4096] >, and STRING as r(s) < default ═ and "[ - ]" >.
S22, define the sub-flow of the complex field acquisition default rule (see later Steps S221 through S224), go to step S23.
S23, judging whether the field of the current general network element configuration is traversed, if yes, ending, otherwise, turning to the step S24.
For example, go through eth _ interface of the general network element configuration XML, port _ mode is a simple field, and l2_ attr is a complex field.
S24, judging whether the current field is a simple field, if yes, going to step S25, otherwise, going to step S26.
I.e., the port _ mode field goes to step S25, and l2_ attr goes to step S26.
S25, the default rule of the current field in the step S21 is taken and added to the output default field rule, and the process returns to the step S23.
I.e., port _ mode, takes the default rule r (w) of WORD in S21.
S26, calling the complex field to obtain the sub-flow of the default rule if the current field is the complex type, and returning to the step S23.
The default rule for a complex field is a set of default rules for a plurality of simple fields or complex fields. Rules like the l2_ attr field are the set of simple field rules for vlan id, svlanid, cvlanid, and vlan _ mode, and field rules for l3_ attr are the set of ip _ addr complex field rules and ip _ mode simple field rules.
Example 5
On the basis of embodiment 4, referring to fig. 5, the sub-flow of the complex field acquiring default rule defined in step S22 is as follows:

S223, the default rule of the current field in the step S21 is taken and added to the output default field rule, and the process returns to the step S221.
S224, the current field is a complex field, the sub-flow of the default rule is obtained by recursively calling the complex field defined in step S22, and the process returns to step S221.
The default rule for simple field X may be denoted as r (X), and the default rule for complex field C, which includes fields Y and Z, may be denoted as r (C) { r (Y), r (Z) }. Two constants are specifically defined: r (w) < default ═ 0 ", value ═ 0-4096" >, r(s) < default ═ and value [ - ] ">. The default rules generated by the above-described S22-S26 processes are as follows:

s31, judging whether the device file is traversed or not, if yes, ending, otherwise, turning to the step S32.
I.e. traverse the two XML files of < network element type 1, single disc type 1> and < network element type 2, single disc type 2> described above.
S32, judging whether the configuration data in the device file is traversed, if yes, returning to the step S31, and if not, going to the step S33.
That is, traverse 2 eth _ interface, 2 l2_ attribute and 1 l3_ attribute in the above two XML files, for a total of 5 configuration data.
S33, judging whether the field of the current configuration data is traversed, if yes, returning to the step S32, and if not, going to the step S34.

S34, judging whether the field of the current configuration data is a simple field, if yes, going to step S35, otherwise going to step S36.
For example, the port _ mode field of eth _ interface in the XML file of < network element type 1, single disc type 1> is a simple field, the transition to step S35, and l2_ attr and l3_ attr are complex fields, and the transition to step S36.
S35, the rule of the current configuration data field in the device file is taken, and the rule, the network element and the single disc type are added into the output device field rule, and the step S33 is returned.
For example, in the port _ mode field, the rule obtained is < default ═ 0 ", value ═ 0-1] >, defined in the XML file of < network element type 1, single disc type 1 >.
S36, if the field of the current configuration data is a complex field, calling the sub-flow of the complex field acquisition device rule (the sub-flow is described by steps S361-S364), and returning to step S33.

S364, if the field of the current configuration data is a complex field, call the sub-process of obtaining the device rule for the complex field S36 itself, and return to step S361.
The sub-flow of S361 to S364 described above is actually a process of sequentially acquiring simple field rules from top to bottom and composing complex field rules.
Similar to the above, for device files of network element type i and single disk type j, the device rule of simple field X can be noted as Ri,j(X), the device rule for complex field C containing fields Y and Z may be denoted as Ri,j(C)＝{Ri,j(Y),Ri,j(Z) }, the device rules generated by the above-mentioned processes of S31 to S36 are shown in table 3:
