Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1:
referring to fig. 1, the present embodiment provides a method for checking network protocol data, where the method includes the following steps:
step 101: establishing a network co-definition file, converting the network co-definition file into a data processing source code, and compiling the data processing source code to obtain a corresponding data processing library. In this embodiment, a network protocol (which may also be referred to as a configuration block) is entered into a protocol management system to generate network protocol definition files, where each of the network protocol definition files includes configuration items included in the configuration block protocol and attribute information of each configuration item.
The network protocol definition file is an xsd file, as shown in fig. 2, is a network protocol definition file corresponding to a "flow classification" network protocol, one network protocol definition file may include one or more primary entry nodes, each primary entry node includes a plurality of configuration items, and each configuration item may further include a sub-entry, as shown in fig. 2, "qos _ class _ module _ item" is a primary entry node, and the primary entry node includes 5 configuration items (xsd: element), and each configuration item has a plurality of attribute information, for example, the attribute information includes: name, Chinese name w: cn, English name w: en, default value default, value range w: range, keyword w: key, etc., in FIG. 2, the English names (w: en) corresponding to the 5 configuration items are "classfier _ name", "classfier _ name _ index", "operator _ type", "qos _ classfier _ match _ rule" and "backup 15".
Wherein, the network co-definition file also comprises the front and back sequence of the configuration items.
And importing the network protocol definition file into a code generation system, converting the network protocol definition file into a data processing source code, and compiling the data processing source code to obtain a corresponding data processing library. The data processing source code has a format conversion function, and may convert the network configuration data into Class of c + + programming language, convert Class into xml, convert xml into Class, convert Class into PB (protocol buffers), convert PB into Class, and the like, for example.
The data processing library is used for realizing the data processing functions of Class2XML, XML2Class, Class2PB and PB2 Class.
The specific type of the data processing library depends on a specific operating system and a programming language, and the data processing library includes a dynamic link library and a Jar package, for example, in a Windows system, the data processing library may be a C + + source code file, in which a C + + data structure of a network protocol is defined, and a Class2XML (Class-to-XML, in C + +, an "object" is described by a "Class", so-called "object" refers to everything in the real world), XML2Class, Class2PB (Class-to-PB, PB is a data description language, structured data can be serialized similarly to XML, and the data processing library can be used for various data processing functions of data storage, communication protocols, and the like), PB2Class, and the like.
In an actual application scenario, the network co-definition file of xsd is added into a code system to obtain a corresponding C + + source code, and the generated C + + source code file is added into a public network protocol data processing source code project to be compiled to generate a DLL (Dynamic Link Library). In Windows, many applications are not a complete executable file, and they are partitioned into relatively independent dynamically linked libraries that are placed in the system. When a program is executed, the corresponding DLL file is called. In actual use, after the network protocol definition file and the dynamic link library are established, the network protocol definition file and the dynamic link library are added into the checking device, and the checking device checks the network protocol data by adopting the network protocol definition file and the dynamic link library.
Step 102: and acquiring a check rule, first data to be checked and second data to be checked, wherein the check rule comprises a target configuration item to be compared.
Before data checking, a setting interface of a checking rule is popped up, all configuration items are displayed on the setting interface, a user can select the configuration items needing to be compared according to needs, the user can edit conditions needing to be met by the network protocol data participating in comparison, and the conditions needing to be met by the configuration items needing to be compared and the network protocol data participating in comparison can be kept as templates or static setting parameters. When setting the checking rule, the user can directly select the existing template.
Step 103: and performing format conversion on the first data to be checked based on the data processing library to obtain first target data, and performing format conversion on the second data to be checked based on the data processing library to obtain second target data.
The first data to be checked can be external data generated by the network equipment, the second data to be checked can be network management data, and the difference between the external data and the network management data is found out by checking the external data and the network management data, so that whether the network equipment has residual data or not is determined, and the residual data is deleted.
In this embodiment, the first target data and the second target data are data in XML format. And converting the first data to be checked and the second data to be checked into XML format data through the data processing library.
As shown in fig. 3, fig. 3 shows xml data, which is external data configured based on the network protocol shown in fig. 2, where the external data includes three flow classification data, and the names of the corresponding flow classification templates are name1, name2, and name3, respectively.
Step 104: and traversing the first target data and the second target data, comparing whether the data information of the target configuration item in the first target data and the second target data has difference or not, and outputting a checking result.
Specifically, first-level entry nodes of the first target data and the second target data are traversed respectively, and if the first-level entry nodes meet the precondition in the check rule, configuration items with keywords are acquired under the first-level entry nodes. The configuration item with the keyword refers to a configuration item with attribute information of "keyword w: key", for example, a configuration item with a Chinese name of "flow classification template name" in fig. 2.
In an actual application scenario, searching a configuration block protocol definition corresponding to the first target data and the second target data in the network protocol definition file, thereby obtaining a configuration item with a keyword; and acquiring values actually given to the configuration items with the keywords from the first target data and the second target data respectively.
For each primary entry node of the first target data, taking the value of the configuration item with the keyword as a primary key value, and forming a key value pair by the primary key value and the corresponding primary entry node to establish a first key value pair set; and aiming at each primary entry node of the second target data, taking the value of the configuration item with the key as a primary key value, and forming a key value pair by using the primary key value and the corresponding primary entry node to establish a second key value pair set.
Taking fig. 2 as an example, a qos _ class _ module _ item node is a piece of data, and the piece of data is characterized by a value of a class _ name (name is a class _ name with w: key 1), so that the value actually given to the class _ name and the qos _ class _ module _ item node form a key-value pair; a "qos _ class _ match _ rule" node is a piece of data, characterized by a match _ type (name with w: key 1), and the value to which the match _ type is actually assigned and the qos _ class _ match _ rule node constitute a key-value pair.
After determining a first set of key-value pairs and a second set of key-value pairs, comparing whether a first target key-value pair and a second target key-value pair with equal primary key values exist between the first set of key-value pairs and the second set of key-value pairs, wherein the first target key-value pair belongs to the first set of key-value pairs, and the second target key-value pair belongs to the second set of key-value pairs; and if so, comparing whether the data information of each target configuration item under the first-level entry node corresponding to the first target key value pair and the first-level entry node corresponding to the second target key value pair is different.
In an actual application scene, acquiring a first target key value pair of which the primary key value exists only in the first key value pair set, and identifying a primary entry node corresponding to the first target key value pair in a specified manner to represent that the primary entry node exists only in the first target data; and acquiring a second target key value pair of which the primary key value only exists in the second key value pair set, and identifying a first-level entry node corresponding to the second target key value pair in a specified mode to represent that the first-level entry node only exists in the second target data.
It can be understood that, in the checking process, the primary key values a of the key values are sequentially taken out from the first key value pair set, and whether the primary key values B equal to the primary key values a exist in the second key value pair set is searched, where the key values to which the primary key values a belong are first target key value pairs, and the key values to which the primary key values B belong are second target key value pairs.
The comparing whether the data information of each target configuration item under the first-level entry node corresponding to the first target key-value pair and the first-level entry node corresponding to the second target key-value pair has a difference specifically includes:
acquiring target configuration items needing to be checked from the first-level entry node corresponding to the first target key value pair and the first-level entry node corresponding to the second target key value pair in sequence; judging whether a sub-entry exists under the target configuration item; and if the sub-entry exists under the target configuration item, the target configuration item is used as the sub-target data of the first target data and the second target data to carry out recursive comparison. In conjunction with fig. 2, assuming that "qos _ class _ module _ item" is a level entry node, and "qos _ class _ match _ rule" is a target configuration item to be compared this time, since two configuration items ("match _ type" and "match _ value") are included under "qos _ class _ match _ rule", it is described that a sub-entry is also included under "qos _ class _ match _ rule", and "qos _ class _ match _ rule" is a sub-node of "qos _ class _ model _ item", and then "qos _ class _ match _ rule" is used as sub-target data to perform recursive comparison in the manner of step 104.
If the sub-item does not exist under the target configuration item, comparing whether the data information under the target configuration item is equal or not; and if so, taking out the next target configuration item from the primary entry node for comparison until the data information under all the target configuration items is equal, and identifying the primary entry node in the first target data and the second target data in a specified manner to represent that the data information of the primary entry node in the first target data and the second target data is equal.
If not, identifying the first-level entry node in the first target data and the second target data in a specified manner to represent that the data information of the first-level entry node in the first target data is not equal to that of the second target data.
In an actual application scenario, outputting a checking result abstract in a table form, wherein the checking result abstract comprises: the values of the configuration items with the keywords corresponding to the first-level entry nodes of the first target data and the second target data are differentiated by different background colors; and after a check detail button in the checking result abstract is selected, outputting checking details through a directory tree interface.
Taking fig. 4 as an example, the external data (the first data to be checked) and the network management data (the second data to be checked) in fig. 3 are checked, where the external data includes three stream classification data, and the names of the corresponding stream classification templates are name1, name2, and name3, respectively. The network management data comprises three flow classification data, the names of the corresponding flow classification templates are name2, name3 and name4 respectively, if the result shows that the name4 only exists in the network management data, and the name1 only exists in the external data. The comparison result of the name2 of the external data and each configuration item of the name2 of the network management data is as follows: the logical relationship of the name2 of the network management data is "OR", the logical relationship of the name2 of the external data is "AND", and the two are different, and the specified color can be adopted for filling.
In this embodiment, the network co-definition file and the data processing library are used for comparing the data to be checked, finding out the configuration items with data message differences, and outputting the checking result, which is beneficial to assisting the user to check the protocol data of the network device more conveniently and quickly, find the residual protocol data of the network device and clear the residual protocol data, and is also beneficial to the development personnel to maintain and expand conveniently and quickly.
In an actual application scenario, a developer can also expand or optimize the scheme of the embodiment, for example, add a check result export report, and implement detection and deletion of network device residual data on the basis of the check result.
