Detailed Description
The method for acquiring the connection relation provided by the embodiment of the application can be applied to the following scenes: in the network, each (lower layer) physical server (which may be a server device or the like) performs information interaction through a (access layer) switch. Wherein the physical server runs a virtual server thereon.
The method for acquiring the connection relationship provided by the embodiment of the application aims to acquire the connection relationship between the switch and the physical server and the virtual server, and then acquire the connection relationship among each switch, each physical server and each virtual server in a network by combining the connection relationship between the switch and the switch.
The technical scheme provided by the embodiment of the application has the innovative point that based on the characteristics of the existing network communication mechanism, the connection relation of the switch, the physical server and the virtual server is extracted from the data product of the existing network communication, so that the universality is realized.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a method for acquiring a connection relationship disclosed in an embodiment of the present application, including the following steps:
s101, acquiring a first corresponding relation through information stored in a switch in a network.
Principle based on network communication: the physical server always needs to access a certain interface of the switch to communicate with the outside, and the switch records the information of the physical server communicating through the switch and the interface information of the physical server. Therefore, the information stored in the switch includes information of the physical server and interface information of the physical server that communicate via the switch. S101 acquires the first correspondence relationship through information stored in the switch.
The information indicates information of a physical server and an interface of the physical server which are communicated through the switch, and the first corresponding relation comprises the corresponding relation between the information of the switch, the interface information of the switch, the information of the physical server and the interface information of the physical server.
It is to be understood that the information of the physical server corresponding to the information of any one switch and the interface information of the switch is information of the physical server communicating through the interface, and the interface information of the physical server corresponding to the information of any one switch and the interface information of the switch is information of the interface of the physical server connected to the interface.
S102, the address of the physical server and the address of the virtual server are read through the interface of the switch, and a second corresponding relation is obtained.
Principle based on network communication: the physical server always needs to be accessed to a certain interface of the switch to communicate with the outside, and the virtual server running on the physical server needs to be accessed to the interface to communicate with the outside, so that the interface of the switch can read the address of the physical server and the address of the virtual server. S102 obtains the second corresponding relationship by reading the address of the physical server and the address of the virtual server through the interface of the switch.
The second corresponding relation comprises interface information of the switch, and a corresponding relation between the physical server and the virtual server.
It is understood that the virtual server corresponding to any one of the physical servers is a virtual server running on the physical server. The physical server and the virtual server corresponding to any interface information are the physical server and the virtual server which are read by the interface to address.
S103, determining a third corresponding relation according to the first corresponding relation and the second corresponding relation.
The third corresponding relation comprises the corresponding relation between the information of the switch, the interface information of the switch, the information of the physical server, the interface information of the physical server and the information of the virtual server.
It can be understood that, with the interface information of the switch and the physical server as a bridge, the third corresponding relationship can be obtained by splicing the first corresponding relationship and the second corresponding relationship.
And S104, generating a network connection relation according to the third corresponding relation and the connection relation between the switches.
The network connection relation indicates the connection relation among all the switches and the connection relation between all the physical servers and all the virtual servers realized through the switches.
Optionally, the connection relationship between the switches may be obtained through a link layer discovery protocol, and a specific implementation manner may refer to the prior art, which is not described herein again.
It can be understood that, in the process described in this embodiment, the existing connection relationship between the switches is expanded to the connection relationship between each switch, each physical server, and each virtual server, which is realized through the switches. Thus, in case of a failure of a certain part (e.g. a switch, a physical server or a virtual server), it is convenient to acquire all other parts (e.g. a switch, a physical server and a virtual server) that are affected.
In addition, the process acquires the data recorded by the network communication from the switch to acquire the corresponding relation according to the principle of the network communication, so the application range is wide, and the universality is high.
The flow shown in fig. 1 will be exemplified in more detail below.
Fig. 2 is a diagram of another method for acquiring a connection relationship, disclosed in an embodiment of the present application, including the following steps:
s201, capturing the identification of each switch, the identification of each interface of each switch and a link layer discovery protocol LLDP table in each switch.
The LLDP table is an important database table on the switch, and is used to record the interconnection relationship between the switch and all the physical servers (including the physical server identifier and the interface identifier of the service server) which are connected downstream and start the LLDP process.
Usually, the switch records its own identity and the identities of its respective interfaces.
Therefore, the correspondence relationship between the identifier of the switch, the interface identifier of the switch, and the LLDP table can be obtained through S201.
Alternatively, the LLDP table may be fetched using a preset protocol, such as SNMP, SSH, or the like.
S202, acquiring the identification of the physical server and the interface identification of the physical server recorded in the LLDP table.
S203, correspondingly storing the identifier of the switch, the interface identifier of the switch, the identifier of the physical server and the interface identifier of the physical server to obtain a first corresponding relation.
Since S201 acquires the correspondence relationship between the identifier of the switch, the interface identifier of the switch, and the LLDP table, it can be understood that, for any LLDP table, the identifier of the physical server and the interface identifier of the physical server recorded therein correspond to the identifier of the switch and the interface identifier of the switch corresponding to the table. That is, the LLDP table is used as a bridge, and the first corresponding relationship is obtained by splicing.
In practice, although the interface of the physical server and the interface of the switch are in a connection state (which may be determined by querying the connection state between the interfaces, for example, the state between a certain interface of the switch and a certain interface of the physical server is "UP"), the physical server is not configured with the LLDP (hereinafter, referred to as a target physical server), and the identifier of the target physical server is not obtained in the LLDP table, so that the information of the physical server having a connection relationship with the interface is missed. To prevent this, in this embodiment, S204-S208 are performed.
S204, capturing a media intervention control MAC address table in the target switch.
The target switch is a switch with a target interface, and the target interface is an interface which has a connection relation with the target physical server. As described above, the target physical server is a physical server that is not configured with the LLDP, that is, a physical server that cannot be searched (information) in the LLDP table.
Although the LLDP table does not look UP the target physical server, the MAC address of the target physical server is recorded in the connected switch because the target physical server communicates through the connected switch (for example, the state between a certain interface of the switch and a certain interface of the physical server is "UP").
Alternatively, the MAC address table may be fetched using a preset protocol, such as SNMP, SSH, or the like.
S205, obtaining the MAC address in the MAC address table as the MAC address to be checked.
S206, inquiring the corresponding relation between the MAC address of the preset physical server and the information of the physical server, and acquiring the identifier of the physical server corresponding to the MAC address to be inquired and the interface identifier of the physical server.
S207, correspondingly storing the identification of the target switch, the interface identification of the target switch, the identification of the physical server and the interface identification of the physical server to obtain a first complementary corresponding relation.
It can be understood that the MAC address to be checked is used as a bridge to obtain a correspondence between the identifier of the target switch, the interface identifier of the target switch, and the identifier of the physical server and the interface identifier of the physical server. The MAC address to be checked corresponding to the target switch is the MAC address in the MAC address table in the target switch.
And S208, merging the supplementary first corresponding relation into the first corresponding relation.
It can be understood that, for the repeated correspondence, one strip is retained after the combination.
In the above process of acquiring the first corresponding relationship, the second corresponding relationship is acquired through S209 to S212 as follows:
s209, capturing the MAC address of the physical server recorded by the interface in the switch as the first MAC address to be checked, and capturing the MAC address of the virtual server recorded by the interface as the second MAC address to be checked.
S210: and inquiring the corresponding relation between the MAC address of the preset physical service and the information of the physical server, and acquiring the identifier of the physical server corresponding to the first MAC address to be inquired and the interface identifier of the physical server.
S211, inquiring the corresponding relation between the MAC address of the preset virtual server and the information of the virtual server, and acquiring the identifier of the virtual server corresponding to the MAC address to be inquired and the interface identifier of the virtual server.
Alternatively, the correspondence between the MAC address of the (physical or virtual) server and the information of the (physical or virtual) server may be queried from an existing mapping relationship database (e.g., CMDB database) between the (physical or virtual) server identifier (e.g., Name/IP/SN, etc.) and the MAC address of the physical network card.
S212, according to the interface, the first MAC address to be searched and the second MAC address to be searched, the interface identifier of the storage switch, the identifier of the physical server, the interface identifier of the physical server, the identifier of the virtual server and the interface identifier of the virtual server are correspondingly stored, and a second corresponding relation is obtained.
It can be understood that, if the first MAC address to be checked and the second MAC address to be checked, which are acquired by the same interface, correspond to the interface, the interface corresponds to the identifier of the physical server corresponding to the first MAC address to be checked and the interface identifier of the physical server, and meanwhile, the interface also corresponds to the identifier of the virtual server corresponding to the second MAC address to be checked and the interface identifier of the virtual server.
S213, determining a third corresponding relation according to the first corresponding relation and the second corresponding relation.
The third corresponding relation comprises a corresponding relation between the identifier of the switch, the interface identifier of the switch, the identifier of the physical server, the interface identifier of the physical server and the identifier of the virtual server.
And S214, generating a network connection relation according to the third corresponding relation and the connection relation between the switches.
The network connection relationship indicates: 1. and connection relations among all the switches. 2. And each physical server is connected through the switch. 3. And the corresponding relation between each virtual server and each physical server. 4. And the virtual servers are connected through the switch.
The process shown in fig. 2 has better versatility, and because the first corresponding relationship is supplemented by the supplemented first corresponding relationship, it is avoided to omit the physical server and the corresponding relationship without LLDP configuration, and therefore, the process has higher accuracy.
Further, the accuracy of the result of the connection relationship can be further improved by improving the accuracy of the corresponding relationship between the physical server and the virtual server, so that fig. 3 shows another method for acquiring a connection relationship disclosed in the embodiment of the present application, including the following steps:
s301, acquiring a first corresponding relation through information stored in a switch in the network.
The specific implementation manner of S301 may be as shown in fig. 2, and is not described here again.
S302, capturing the MAC address of the physical server recorded by the interface in the switch as a first MAC address to be checked, and capturing the MAC address of the virtual server recorded by the interface as a second MAC address to be checked.
S303, acquiring the corresponding relation between the physical server and the virtual server from the monitoring API.
Executing the following steps for each pair of corresponding relations acquired from the monitoring API one by one:
s304, judging whether the corresponding physical server and the virtual server acquired from the monitoring API are recorded by the same interface, if so, executing S305-S307, and if not, executing S308.
Wherein, the monitoring API can be a device configured for the existing 'cloud' architecture for monitoring the virtual machine. The device stores the corresponding relation between the physical server and the virtual server.
S305, inquiring the corresponding relation between the MAC address of the preset physical service and the information of the physical server, and acquiring the identifier of the physical server corresponding to the MAC address to be inquired and the interface identifier of the physical server.
S306, inquiring the corresponding relation between the MAC address of the preset virtual server and the information of the virtual server, and acquiring the identifier of the virtual server corresponding to the MAC address to be inquired and the interface identifier of the virtual server.
S307, correspondingly storing the interface identifier of the switch, the identifier of the physical server, the interface identifier of the physical server, the identifier of the virtual server and the interface identifier of the virtual server according to the interface, the first MAC address to be searched and the second MAC address to be searched to obtain a second corresponding relation.
And S308, sending out manual checking prompt information.
The manual verification prompt information is used for prompting that the corresponding relation between the physical server and the virtual server, which is acquired by two different channels, is inconsistent, so that manual intervention verification is required.
S309, determining a third corresponding relation according to the first corresponding relation and the second corresponding relation.
And S310, generating a network connection relation according to the third corresponding relation and the connection relation between the switches.
In the process shown in fig. 3, the corresponding relationships between the physical server and the virtual server are respectively obtained through different channels, and if the corresponding relationships obtained by the two channels are inconsistent, manual checking is prompted without recording in the second corresponding relationship, so that the accuracy of the second corresponding relationship can be improved, and the accuracy of the connection relationship is further improved.
It should be noted that the execution order of the steps in the flow shown in fig. 3 is only an example, in which the occupation amount of the resources is smaller than that in other examples, but is not limited to the execution order. The determining step is performed before the parameters are stored correspondingly to obtain the second corresponding relationship, so that the step of obtaining the second corresponding relationship is limited by the determining result.
