The local area network technology with active exchange elements is adopted, the network transmission delay is small, the transmission medium is mainly an optical cable, and the transmission rate is generally more than 100 Mbit/s. The transformation of the two-layer equipment of the metropolitan area network is an important aspect of the construction of the metropolitan area network.
in the process of transforming the two-layer device of the metropolitan area network, three-layer gateway information corresponding to the two-layer device needs to be collected and positioned.

On one hand, if a large number of slave IP addresses exist in the three-layer gateway information, the efficiency of collecting and positioning the three-layer gateway information is greatly reduced. For example, a common metro network device contains at least 1 ten thousand rows of global configuration data, and it may take at least 60 minutes to 90 minutes, or even longer, to manually gather and locate all eligible three-tier gateway information, resulting in very inefficient location of three-tier gateway information. On the other hand, after a large amount of data is processed, due to fatigue and other reasons caused by long-time operation, part of three-layer gateway information may be omitted in the positioning process, or wrong three-layer gateway information may be positioned, so that the positioned three-layer gateway information is inaccurate, and further modification or migration errors of corresponding two-layer equipment may be caused.
therefore, the existing manual positioning three-layer gateway information has the problems of low efficiency and low accuracy.

Detailed Description
in order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Fig. 1 shows an implementation flow of a metro network three-layer gateway information positioning method provided in an embodiment of the present invention, and for convenience of description, only parts related to the embodiment of the present invention are shown, which are detailed as follows:
as shown in fig. 1, the method for locating information of a metro network three-layer gateway includes:
step 101, acquiring global configuration data of a three-layer gateway in a metropolitan area network;
102, determining gateway configuration keywords and configuration data corresponding to the gateway configuration keywords according to global configuration data of three layers of gateways in a metropolitan area network; the gateway configuration keywords comprise interface keywords and IP address keywords, and the configuration data corresponding to the gateway configuration keywords comprise IP address configuration data corresponding to the IP address keywords and interface configuration data corresponding to the interface keywords;
And 103, determining interface configuration data corresponding to the IP address of the at least one two-layer device according to the IP address configuration data and the interface configuration data corresponding to the IP address configuration data.
in the embodiment of the present invention, the global configuration data of the three-tier gateway is generally stored in the text file in the form of software code. Therefore, when the global configuration data of the three-layer gateway is obtained, all the configuration data of the three-layer gateway in the metro network, namely the full-bright configuration data of the three-layer gateway, can be obtained by directly reading the code content of the text file containing the configuration data of the three-layer gateway.
After the global configuration data of the three-layer gateway in the metropolitan area network is obtained, screening is carried out through the gateway configuration keywords according to the global configuration data of the three-layer gateway in the metropolitan area network, and the gateway configuration keywords and the configuration data corresponding to the gateway configuration keywords are selected. The gateway configuration key words uniquely identify the configuration data corresponding to the gateway configuration key words in the gateway configuration data, and the gateway configuration key words and the configuration data corresponding to the gateway configuration key words are in the same row of codes. For example, by identifying and screening the gateway configuration key, a code line including the gateway configuration key and the configuration data corresponding to the gateway configuration key is extracted.
In the embodiment of the present invention, the gateway configuration keywords at least include interface keywords (e.g., interface and the like) and IP address keywords (e.g., IP address and the like). Therefore, the configuration data corresponding to the interface keyword is interface configuration data, and the interface configuration data reflects interface information; the configuration data corresponding to the IP address keywords are IP address configuration data, and the IP address configuration data reflects IP address information.
Further, since the code line including the interface key and the interface configuration data corresponding to the interface key is followed by the code line including the IP address key and the IP address configuration data corresponding to the IP address key, it can be said that the interface configuration data and the IP address configuration data have a specific correspondence relationship. That is, according to the code line including the interface keyword and the interface configuration data corresponding to the interface keyword, and the code line following the code line and including the IP address keyword and the IP address configuration data corresponding to the IP address keyword, the corresponding relationship between the interface configuration data and the IP address configuration data can be determined.
For example, assume that the filtered gateway configuration keywords and the configuration data corresponding to the gateway configuration keywords are in the following form:
It can be determined accordingly that the IP address configuration information b1 and the interface configuration information a1 have a corresponding relationship, and the IP address configuration information c1 and the interface configuration information a1 also have a corresponding relationship. In addition, it can also be determined that there is a correspondence relationship between the IP address configuration information b2 and the interface configuration information a 2.
Screening all code lines containing the gateway configuration keywords and the configuration data corresponding to the gateway configuration keywords through the step of utilizing the gateway configuration keywords, and carrying out primary screening and matching on the global configuration data of the three-layer gateway.
because the IP address of the two-layer device and the IP address configuration data in the global configuration data of the three-layer gateway have a corresponding relation, the IP address configuration data obtained by screening can be compared with the IP address of the two-layer device to be modified for screening, the IP address configuration data corresponding to the IP address of the two-layer device is determined, and then the interface configuration data corresponding to the IP address of the two-layer device is positioned according to the corresponding relation between the IP address configuration data and the interface configuration data.
wherein, the IP address of the two-layer device to be modified is known, and there may be one or more two-layer devices to be modified. In most cases, there are a plurality of two-layer devices to be modified. Then, a layer two device corresponds to a known layer two device IP address, and a layer two device IP address can locate an interface configuration data corresponding thereto. The plurality of two-layer device IP addresses can form a two-layer device IP address management list, so that interface configuration data corresponding to each two-layer device IP address of the two-layer device IP address management list in a one-to-one mode is obtained through the method steps.
In the embodiment of the invention, the global configuration data of the three-layer gateway in the metro network is obtained, the gateway configuration key words and the configuration data corresponding to the gateway configuration key words are determined according to the global configuration data of the three-layer gateway, namely, the interface key words and the interface configuration information corresponding to the interface key words, and the IP address key words and the IP address configuration information corresponding to the IP address key words are determined, and further, based on the screened IP address configuration data, the interface configuration data corresponding to the known IP address of the two-layer device is determined (positioned) according to the corresponding relation between the IP address configuration data and the interface configuration data, compared with the traditional method of utilizing a manual positioning interface, the efficiency of positioning the interface configuration data in the three-layer gateway can be greatly improved, and the problem of positioning wrong interface configuration data caused by manual fatigue can be avoided, the accuracy of positioning the interface configuration data in the three-layer gateway is improved.
through research and measurement, according to configuration data of ten thousand rows of three-layer gateways and nearly 400 two-layer devices to be modified (each two-layer device corresponds to one IP address), the interface of the three-layer gateway corresponding to the IP addresses of the 400 two-layer devices can be accurately positioned only in one minute at most, the efficiency of positioning the interface configuration data in the three-layer gateway is greatly improved, and meanwhile, the accuracy of positioning the interface configuration data in the three-layer gateway can be improved.
fig. 2 shows an implementation flow of step 103 in the metro network three-layer gateway information positioning method provided in the embodiment of the present invention, and for convenience of description, only the parts related to the embodiment of the present invention are shown, which is detailed as follows:
in an embodiment of the present invention, as shown in fig. 2, step 103, determining interface configuration data corresponding to an IP address of at least one layer two device according to the IP address configuration data and the interface configuration data corresponding to the IP address configuration data, includes:
step 201, converting a standard mode mask of IP address configuration data into a digital mode mask;
Step 202, determining IP address configuration data corresponding to at least one IP address of the two-layer device by performing IP address subnet division on the IP address configuration data containing the digital mode mask;
step 203, determining interface configuration data corresponding to the IP address of the at least one layer two device according to the interface configuration data corresponding to the IP address configuration data.
In the embodiment of the present invention, the IP address configuration data includes a mask, and the mask of the screened IP address configuration data is a standard format mask. Standard format masks, i.e., masks in the form of, for example, 255.255.255.192, 255.255.255.0, etc.
Specifically, when interface configuration data corresponding to the IP address of the second-tier device is determined, in order to screen and compare the IP address configuration data in the third-tier gateway configuration data with the IP address of the second-tier device, a standard format mask included in the IP address configuration data is converted into a digital mode mask. The digital pattern mask is a mask of the form/24/,/15, and/10, etc. For example, the standard format mask 255.255.255.0 is converted to a digital pattern mask/24, the standard format mask 255.255.255.192 is converted to a digital pattern mask/26, and so on. The conversion of the standard format mask into the digital pattern mask is well known in the art and will not be described in detail herein.
After the standard mode mask of the IP address configuration data is converted into the digital mode mask, the IP address configuration data comprises the converted digital mode mask, and then IP address subnet division is carried out on the IP address configuration data comprising the digital mode mask. The IP address subnet division refers to dividing IP address configuration data according to a certain rule. For example, certain IP address configuration data 123.123.46./26 is divided into 123.123.46./1, 123.123.46./2, 123.123.46./3. 123.123.46./62, and 123.123.46./63 by IP address subnet partitioning. IP address subnet partitioning is well known in the art and will not be described in detail herein.
After IP address subnet division is carried out on the IP address configuration data, the result of the IP address subnet division is compared with the known IP address of the two-layer device, the IP address subnet division result which is consistent with the IP address of the two-layer device is screened out from the result of the IP address subnet division, and then the IP address configuration data corresponding to the IP address of the two-layer device is determined according to the consistent IP address subnet division result. And after determining the IP address configuration data corresponding to the IP address of the two-layer equipment, further determining the interface configuration data corresponding to the IP address of the two-layer equipment according to the interface configuration data corresponding to the IP address configuration data.
In the embodiment of the invention, the standard mode mask of the IP address configuration data is converted into the digital mode mask, the IP address subnet division is carried out on the IP address configuration data containing the digital mode mask, the IP address configuration data corresponding to the IP address of the at least one two-layer device is determined, and then the interface configuration data corresponding to the IP address of the at least one two-layer device is determined according to the interface configuration data corresponding to the IP address configuration data, so that the efficiency and the accuracy of positioning the interface configuration data in the three-layer gateway can be further improved.
In an embodiment of the present invention, the IP address configuration data includes a master IP address and a slave IP address, and the corresponding relationship between the IP address configuration data and the interface configuration data is determined as follows:
And respectively determining the corresponding relation between the master IP address and the interface configuration data and the corresponding relation between the slave IP address and the interface configuration data.
In the embodiment of the invention, the IP address configuration data mainly comprises a master IP address and a slave IP address. Specifically, the master IP address and the slave IP address may be determined and distinguished by the following form:
The IP address d1 in the 2 nd line code is the master IP address, and the IP addresses e1 and f1 with the identifiers sub in the 3 rd line code and the 4 th line code are the slave IP addresses.
based on the above, when the corresponding relationship between the IP address configuration data and the interface configuration data is determined, the corresponding relationship between the master IP address and the interface configuration data and the corresponding relationship between the slave IP address and the interface configuration data are determined respectively. It can be seen that the code line 1 containing the interface key and the interface configuration data corresponding to the interface key, the interface configuration data corresponding to the IP address d1 in the code line 2 at the bottom, the interface configuration data corresponding to the slave IP address e1 in the code line 3, and the interface configuration data corresponding to the slave IP address f1 in the code line 4 are the same interface configuration data a 1.
in addition, when the correspondence between the slave IP address and the interface configuration data is determined, the code line including the interface key and the interface configuration data corresponding thereto may be inserted before each code line including the IP address key and the slave IP address corresponding to the IP address key, the interface key in the inserted code line may be deleted, the interface configuration information may be retained, the IP address key in the code line including the IP address key and the slave IP address corresponding to the IP address key may be deleted, the slave IP address may be retained, and the correspondence between the retained interface configuration information and the slave IP address may be determined.
For example, determining the correspondence between the slave IP address and the interface configuration information is illustrated by the following configuration data:
deleting the interface key a1 in the code line 1, reserving the interface configuration information a1, deleting the IP address key in the code line 2, reserving the slave IP address e1, and thus determining the correspondence between the slave IP address e1 and the interface configuration information a 1.
In addition, when the correspondence between the slave IP address and the interface configuration information is determined, the correspondence between the slave IP address e1 and the interface configuration information a1 may be determined by directly identifying or extracting the interface configuration information a1 and the slave IP address e 1.

The code line including the third configuration key and the third configuration data corresponding to the third configuration key is generally below the corresponding code line including the interface key and the interface configuration data corresponding to the interface key, and is represented by the following expression:
when determining the corresponding relationship between the third configuration data and the interface configuration data a1, the principle of determining the corresponding relationship between the IP address configuration data and the interface configuration data in the above embodiment is similar, and for details, reference is made to the corresponding description of determining the corresponding relationship between the IP address configuration data and the interface configuration data, which is not described herein in detail.
