According to an embodiment of the application, a method for determining a topological relation of devices in a network is provided.
Fig. 1 is a flowchart of a method for determining a topological relation of devices in a network according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S101, determining a first node device and a second node device in the local area network, where the first node device is a server, and the second node device is a network device.
Specifically, when determining the topology of the network device, it is necessary to first obtain a target first node device and a target second node device that need to be determined in the local area network, where the target first node device may be a target server, for example, a target server in a system, and the target second node device may be a target network device, for example, a target core switch and a target access switch in the system.
Step S102, obtaining port information of a third node device from the port configuration information of the first node device, wherein the third node device is the node device connected with the first node device.
In particular, the third node device may be a network device connected to the server. After logging in the target server device, the port configuration information of the target server may be obtained by a command program, for example, a command program such as "share" or "display ARP", and the port configuration information is obtained from the port configuration information, so as to obtain the connection relationship between the target server and the plurality of core switches, and obtain MAC (Message Authentication Code message authentication code) information of the target server.
After a plurality of core switches matched with the target server are obtained, the plurality of core switches are logged in, a port configuration file of the core switches, for example, a 'sh MAC-address' program, etc., can be obtained through a command program, and a device port with the same MAC information as the target server in the port configuration file is obtained through the MAC information of the target server, so that port information connected with the target server is obtained, and a device port connected with the target server is obtained.
Step S103, obtaining port information of the fourth node equipment from the port configuration information of the second node equipment, and obtaining the port information of the fourth node equipment through the port description information of the second node equipment under the condition that the port information of the fourth node equipment does not exist in the port configuration information of the second node equipment, wherein the fourth node equipment is the node equipment connected with the second node equipment.
In particular, the fourth node device may be a network device connected to the target network device. After the target network device is determined, configuration information of the target network device is obtained, port information in the device configuration file is read through a command program, for example, an interface program is used for obtaining the network device correspondingly connected with the target network device through the port information.
When the port information in the device configuration information is read by the command program, there may be a case where there is no corresponding port information, and at this time, the port description information in the port configuration information may be acquired, and the port information of the network device corresponding to the target network device may be acquired by the port description information.
Step S104, determining the topological relation information of the first node equipment and the second node equipment in the local area network according to the port information of the third node equipment and the port information of the fourth node equipment.
Specifically, after the connection relationship between the target server and the network device and the connection relationship between the target network device and the network device are obtained, that is, the connection relationship between the target server and the target network device in the local area network is already confirmed, all the connection relationships are determined as topology relationship information of the network device in the local area network.
The method for determining the topological relation of the devices in the network comprises the steps of determining first node devices and second node devices in a local area network, wherein the first node devices are servers, and the second node devices are network devices; acquiring port information of third node equipment from port configuration information of the first node equipment, wherein the third node equipment is node equipment connected with the first node equipment; acquiring port information of fourth node equipment from port configuration information of second node equipment, and acquiring the port information of the fourth node equipment through port description information of the second node equipment under the condition that the port information of the fourth node equipment does not exist in the port configuration information of the second node equipment, wherein the fourth node equipment is node equipment connected with the second node equipment; and determining topological relation information of the first node equipment and the second node equipment in the local area network according to the port information of the third node equipment and the port information of the fourth node equipment. The method solves the problem that the topological relation between devices in the network cannot be determined efficiently and accurately in the related art. The port information is acquired from the network equipment, the port information corresponding to the network equipment is acquired through the port description information under the condition that the port information cannot be acquired, and the port information of the local network equipment is confirmed and added in the opposite-end network equipment, so that the effect of accurately and efficiently determining the topology relation information of the network equipment in the local area network in a mode of inquiring the corresponding port information in the network equipment is achieved.
Optionally, in the method for determining a topology relationship of devices in a network provided in the embodiment of the present application, obtaining port information of a fourth node device from port configuration information of a second node device includes: inputting a first command in the second node equipment, and receiving a first return value corresponding to the first command, wherein the first command is used for requesting to acquire configuration information; and inquiring port information in the first return value through the port information key words, and determining the port information obtained by inquiring as port information of the fourth node equipment.
Specifically, the first command is used for acquiring information of the opposite terminal network device in the configuration information from the target network device, for example, acquiring the opposite terminal network device information through a "sh cdp" command, acquiring a keyword through analyzing the opposite terminal network device information in the opposite terminal network device information, and determining port information of the opposite terminal network device through the keyword.
For example, for the class a target network device, the information of the peer network device may be obtained through a "sh cdp" command, then the keyword "IPv4" in the returned peer network device information is obtained, so as to identify the class a target network device, then the remaining keywords in the returned peer network device information, such as a system name, a device ID, etc., are obtained to obtain the main information of the peer network device port included in the returned information, then the keywords in the main information are parsed, and the peer port information such as the peer network device IP, the peer network device port type, the port IP, etc., is obtained.
It should be noted that, for the class B target network device, the location of the opposite terminal network device information may be located by using a keyword such as a device ID, and then the returned keyword in the opposite terminal network device information is also parsed to obtain the opposite terminal network device information. For the class-B target network device, after the opposite-end network device information is acquired through a dis-ldp command, the keywords in the returned opposite-end network device information, such as Local, interface, and the like, are acquired to acquire the opposite-end network device IP, the opposite-end network device name, the opposite-end network device port type, and the like. According to the method, the device and the system, the port information searching mode is adopted for different devices by using different keywords, and the effect of accurately and efficiently acquiring the opposite port information connected with the network device is achieved.
Optionally, in the method for determining a topology relationship of devices in a network provided in the embodiment of the present application, when port information of a fourth node device does not exist in port configuration information of a second node device, obtaining, by port description information of the second node device, port information of the fourth node device includes: acquiring a configuration file of the second node equipment, and acquiring port description information from the configuration file; converting the port description information into a target format, and analyzing the converted port description information to obtain an analysis result; and determining the port information of the opposite node equipment as the port information of the fourth node equipment when the port information of the opposite node equipment exists in the analysis result, wherein the opposite node equipment is different from the second node equipment.
Specifically, because the existing network device port descriptions in the system are not unified and standardized, the situation that the names of the opposite-end network devices and the opposite-end ports in the port descriptions cannot be resolved correctly may occur, so that the port information of the opposite-end network devices cannot be found. For the opposite-end network device incapable of finding the port information, the port description information in the configuration file of the target network device can be acquired first, the port description information is normalized, and then the normalized port description information is analyzed, so that the opposite-end port information is acquired.
The normalization of the port description mainly has two cases, one is the physical port where the device actually exists, and the port description is normalized into a 'to_ $device name_ $port name'; the other is a logical port connected by a peer-link mode of the device, and the port description is normalized into a 'Peerlink_ $device name_ $port name'. After the device port description is normalized, the port description information can be parsed to obtain the opposite port information such as the opposite network device name, the opposite port name and the like. The embodiment achieves the effect of acquiring the opposite port information connected with the network equipment under the condition that the port information of the network equipment connected with the target network equipment does not exist in the port configuration information of the target network equipment.
Optionally, in the method for determining a topology relationship of devices in a network provided in the embodiment of the present application, when port information of a peer node device exists in an analysis result, determining the port information of the peer node device as port information of a fourth node device includes: under the condition that port information of the opposite terminal node equipment exists in the analysis result, acquiring a configuration file of the opposite terminal node equipment; acquiring port description information from a configuration file of the opposite node equipment, and determining whether port information of the second node equipment exists in the acquired port description information; and determining the port information of the opposite node equipment as the port information of the fourth node equipment under the condition that the port information of the second node equipment exists in the acquired port description information.
Specifically, in order to ensure accuracy of the opposite port information, after determining the opposite port information of the target network device, the port description information of the opposite network device needs to be analyzed in the same way, so as to determine whether the port description information of the opposite network device can be successfully matched with the port information corresponding to the target network device. After the successful matching is determined, the port information of the opposite terminal network device can be determined as the port information of the network device connected with the target network device, and the port information of the target network device and the port information of the opposite terminal network device are determined to be correct, so that the port information can be updated and stored. The embodiment achieves the effect of enabling port information of the local network equipment and port information of the opposite network equipment to be consistent.
Optionally, in the method for determining a topological relation of a device in a network provided by the embodiment of the present application, after converting port description information into a target format and analyzing the converted port description information to obtain an analysis result, the method further includes: under the condition that port information of opposite-end node equipment does not exist in the analysis result, the equipment name of the second node equipment, the target port name of the second node equipment and the equipment name of the opposite-end node equipment are input into a target model, the port name of the opposite-end node equipment corresponding to the target port is obtained through processing, wherein the target model is obtained through training of multiple groups of sample data, and each group of sample data comprises the equipment name of the sample node equipment, the target port name of the sample node equipment, the equipment name of the opposite-end node equipment of the sample node equipment and the port name of the opposite-end node equipment corresponding to the target port name; and adding the port name of the fourth node equipment to the port information of the fourth node equipment.
Specifically, in the case where the port information of the opposite-end network device is not acquired due to the lack of the port name in the port description information, the acquisition of the opposite-end port information may also be performed through a DRCN model (Densely-connected Recurrent and Co-attentive information text similarity model) in the neural network. Before obtaining the opposite terminal port information through the DRCN model in the neural network, training the DRCN model by using a sample set, wherein the sample set can be known local terminal network equipment name, the local terminal network equipment port name, the opposite terminal network equipment name in the port description information of the local terminal network equipment, and the opposite terminal network equipment port name. And inputting the sample set into a DRCN model, obtaining a predicted opposite end network equipment port name by the DRCN model through the local end network equipment name, the local end network equipment port name and the opposite end network equipment name in port description information of the local end network equipment, comparing the predicted opposite end network equipment port name with the opposite end network equipment port name to obtain a correct rate, and continuously optimizing parameters of the DRCN model to enable the correct rate to meet the requirement. The embodiment achieves the effects of optimizing the DRCN model and acquiring port information by using the optimized DRCN model.
Optionally, in the method for determining a topological relation of devices in a network provided in the embodiment of the present application, inputting a device name of a second node device, a target port name of the second node device, and a device name of a peer node device into a target model, and processing to obtain a port name of a fourth node device includes: inputting the equipment name of the second node equipment, the target port name of the second node equipment and the equipment name of the opposite terminal node equipment into a target model, and processing to obtain the scores of the port names of the opposite terminal node equipment; and comparing the score of each port name with a score threshold value, and determining the port name with the score greater than or equal to the score threshold value as the port name of the opposite-end node equipment corresponding to the target port.
In particular, it may be assumed that the device name of the target network device is x 1 The port name of the target network device is x 2 The name of the opposite end network device in the port description information of the target network device may be y 1 . First, the device name of the network device is obtained as y 1 Port information (including port description information) { y of all network devices a ,y b ,y c ,...,y t After } x is 1 、x 2 And y j ＝{y a ,y b ,y c ,...,y t The word vector generated by the embedding layer is used as the input of the DRCN model, and then the similarity score of the word vector and the DRCN model is obtained by softmax (loss function) processing. In the DRCN model, a description (self-attention) mechanism can be used to calculate cosine similarity before passing through softmax, as in equation (1), softmax is processed as in equation (2), so the final score is a weighted score through softmax, as in equation (3):
e x,y ＝cos(x 1 x 2 ,y j ) (1)
As above, J is the total number of opposite end network devices of the target network device, a pi I.e. the final calculated score, and so on, all y are calculated j And x 1 、x 2 Finally, the score of y with the highest score is obtained m Comparing the highest score with a threshold value, and when the highest score is greater than or equal to the threshold value, taking port information of the network equipment corresponding to the highest scoreAnd judging that the opposite terminal port information in the port description information of the target network equipment is empty, namely no opposite terminal port information, when the highest score is smaller than the threshold value as the port information of the opposite terminal network equipment.
For example, the score threshold is 0.7, if the highest score is 0.5, the opposite terminal port information in the port description information of the target network device is determined to be null, and if the highest score is 0.8, the port information of the network device corresponding to the score of 0.8 is taken as the port information of the opposite terminal network device. The embodiment achieves the effect of acquiring the port information of the opposite-end network equipment of the target network equipment through the port description information.
Optionally, in the method for determining a topology relationship of devices in a network provided in the embodiment of the present application, obtaining port information of a third node device from port configuration information of a first node device includes: inputting a second command in the first node equipment and receiving a second return value corresponding to the second command; determining the MAC address of the first node device and the core node device connected with the first node device from the second return value, wherein the second command is used for acquiring port configuration information; receiving a third command through the core node equipment, receiving a third return value corresponding to the second command, and acquiring port information of access node equipment corresponding to the MAC address of the first node equipment from the third return value, wherein the third command is used for acquiring port configuration information; port information of the access node device is determined as port information of the third node device.
Specifically, the core node device may be a core network device connected to a server, and after logging in the target server, the port configuration information in the target server may be obtained through a second command, for example, a command such as "share" or "display ARP". After the port configuration information in the target server is successfully obtained, the port configuration information of the core network equipment can be read, and the connection relationship between the target server and the core network equipment is obtained by searching according to a specific regular expression, and meanwhile, the MAC information of the target server is obtained.
It should be noted that, after obtaining the connection relationship between the core network device and the target server, the port configuration information of the core network device, such as a command "sh mac-address", may be obtained through the third command. And then reading port configuration information of the core network equipment, and searching according to a specific regular expression to obtain MAC of the non-core network equipment, thereby obtaining the network equipment port information identical to the MAC of the target server.
