The invention provides a system for determining network topology, as shown in fig. 1, comprising:
the system comprises an automatic acquisition server 101, a switch 102, a physical server 103, a virtual server 104 carried by the physical server 103, a database server 105 and a front-end display server 106.
In the embodiment of the present invention, when the automatic acquisition server 101 needs to determine the current network topology, the automatic acquisition server 101 obtains the configuration parameters of the switch 102.
Optionally, the automatic acquisition server 101 may periodically determine the current network topology, that is, a countdown clock may be set in the automatic acquisition server 101, and when the period arrives, the configuration parameters of the switch 102 are obtained; the automatic acquisition server 101 may further determine the network topology of the current network through an update message sent by the database server 105, and when determining that the number of switches 102 in the current network changes or the physical server 103 changes, or the virtual server 104 migrates, the data block server 105 sends an update request to the automatic acquisition server 101.
In the embodiment of the present invention, since a plurality of switches 102 are arranged in a network, manufacturers of each switch 102 are different, and parameters of each switch 102 are also different, before a call instruction is sent to the switch 102, configuration parameters of each switch 102 in the network also need to be obtained, for example, 4 switches 102 are arranged in the current network, which are respectively a switch 1, a switch 2, a switch 3, and a switch 4, the switch 1 and the switch 2 are produced by the same manufacturer, the configuration parameters of the switch 1 and the switch 2 are the same and are the configuration parameters 1, manufacturers of the switch 3 and the switch 1, the switch 2, and the switch 4 are different, the configuration parameter of the switch 3 is the configuration parameter 2, manufacturers of the switch 4 and the switches 1, 2, and 3 are different, and the configuration parameter of the switch 4 is the configuration parameter 3.
In the embodiment of the present invention, the automatic acquisition server 101 generates a call instruction according to the acquired configuration parameter of each switch 102, where the call instruction refers to a command that the switch 102 can acquire a first network topology relationship of the physical server 103 connected to or called by the switch 102 according to the call instruction.
Optionally, in the embodiment of the present invention, the call instruction is an SNMP (Simple Network management protocol) command, and the switch 102 can obtain, according to the SNMP command, a Network topology of the physical server 103 called by the switch 102 and set the Network topology as the first Network topology.

Optionally, in the embodiment of the present invention, the SNMP parameters of each switch 102 acquired by the automatic acquisition server 101 may be stored in the automatic acquisition server 101 or acquired from the database server 105.
After the automatic acquisition server 101 acquires the SNMP parameters of each switch 102, it generates SNMP call instructions according to the SNMP parameters and sends the SNMP call instructions to the corresponding switches 102.
For example, in the embodiment of the present invention, after the SNMP commands are executed by 3 switches 102, the connection relationship between the port of each switch 102 and the switch 1 is fed back. As shown in fig. 1, there are 3 switches 102 in the current network, which are switch 1, switch 2, and switch 3; the switch 1 is connected with the physical server 1 and the physical server 2, and the switch 2 is connected with the physical server 3 and the physical server 4; the switch 3 is connected to a physical server 5.
Optionally, in the embodiment of the present invention, each switch 102 acquires a correspondence table between a port of the switch 102 and a MAC address of the physical server 103, for example, as shown in table 1, the above-mentioned topological relationship is represented by a correspondence table between a port of the switch 103 and a MAC address of the physical server 103:
table 1: correspondence table of ports of switch and MAC addresses of physical servers
In the embodiment of the present invention, the correspondence between the MAC address of the physical server 103 and the identification information of the physical server 103 is stored in the automatic acquisition server 101, and the identification information of the physical server 103 is determined by the correspondence.
Alternatively, in order to reduce the load in the automatic acquisition server 101, the automatic acquisition server 101 may acquire the correspondence between the MAC address of the physical machine 103 and the identification information of the physical server 103 from the database server 105, and then determine the first network topology of the switch 102 and the physical server 103 connected in the port of the switch 102.
In the embodiment of the present invention, after the first network topology is obtained, the call relationship between the virtual server 104 and the switch 101 needs to be determined.
In the embodiment of the present invention, the automatic acquisition server 101 sends a detection instruction to the physical server 103, where the detection instruction is a virtual machine detection program running in the physical server 103. The virtual machine detection program detects the call relationship between the virtual server 104 carried in the physical server 103 and the switch 101.
Optionally, in the embodiment of the present invention, in order to obtain the topology of the virtual server 104 of two virtualization technologies commonly used in the prior art, the virtual machine probe can provide at least two interfaces corresponding to the two virtualization technologies.
Optionally, in the embodiment of the present invention, in the prior art, two common virtualization technologies are Xen and KVM, the virtual machine detection program is libvert, libvirt is a set of free and open-source main stream virtualization tool API under Linux, libvirt may provide a set of convenient and reliable programming interfaces for various virtualization tools including Xen and KVM, support binding with programming languages such as C, C + +, Python, and the like, and may rapidly develop and manage KVM and Xen virtual server programs based on libvirt library, that is, obtain a topological relationship between Xen and KVM by using libvert.
Optionally, in the embodiment of the present invention, in order to reduce the problem of resource occupation in the current network, before sending the detection instruction to the physical server 103, the automatic acquisition server 101 first determines whether the physical server 103 is the physical server 103 bearing the virtual server 104.
Optionally, in the embodiment of the present invention, after the automatic acquisition server 101 acquires the physical server 103 connected to the switch 102, the automatic acquisition server 101 stores information whether each physical server 103 is the physical server 103 bearing the virtual server 104, and determines whether the physical server 103 is the physical server 103 bearing the virtual server 104 according to the acquired identification information of the physical server 103 in the first network topology.
Optionally, in the embodiment of the present invention, after acquiring the physical server 103 connected to the switch 102, the automatic acquisition server 101 acquires, from the database server 105, information on whether each physical server 103 is the physical server 103 bearing the virtual server 104, and determines whether the physical server 103 is the physical server 103 bearing the virtual server 104 according to the acquired identification information of the physical server 103 in the first network topology.
When the automatic acquisition server 101 determines that the physical server 103 connected to the switch 101 is the physical server 103 carrying the virtual server 104, a virtual machine detection program is called, and the virtual machine detection program is pushed to the physical server 103.
For example, as shown in fig. 2, there are two physical servers 103 connected to the switch 101, which are a physical server a and a physical server B, respectively, where the automatic acquisition server 101 determines that the physical server a is the physical server 103 carrying the virtual server 104, and then the automatic acquisition server 101 calls the virtual machine detection program and sends the virtual machine detection program to the physical server a.
The automatic acquisition server 101 sends a detection instruction to the physical server a, and after receiving the detection instruction, the physical server a runs a virtual machine detection program, optionally libvert, in the physical virtual server a.
When the physical server a runs the virtual machine detection program, a detection result is obtained. Optionally, in this embodiment of the present invention, the detection result includes attribute information of each virtual server 104 carried in the physical server a.
Optionally, the attribute information of each virtual server 104 may be an IP address or a domain name of each virtual server 104, or may be network card information of each virtual server 104, and the like.
When the switch 102 returns the detection result to the automatic acquisition server 101, the automatic acquisition server 101 determines the second network topology of the virtual servers 104 according to the attribute information of each virtual server 104 in the detection result.
Optionally, the automatic acquisition server 101 stores attribute information of the switch 102 and the physical server 103 in the current network, and if it is determined that the attribute information of the virtual server 104 matches the attribute information of the switch 102 or the physical server 103, it is determined that a topological relationship exists between the two.

For example, in the embodiment of the present invention, after the virtual machine detection program is run in the physical server a, the obtained detection result includes the IP addresses of the virtual server 1, the virtual server 2, and the virtual server 3, which correspond to the IP address 1, the IP address 2, and the IP address 3, respectively.
The automatic acquisition server 101 determines the switch 102 and the physical server 101 matched with the three IP addresses according to the three IP addresses, determines that the virtual server 1 is matched with the physical server a, and determines that the virtual server 2 and the virtual server 3 are matched with the switch 102, so that the second network topology is as shown in fig. 3.

Optionally, in the embodiment of the present invention, the automatic acquisition server 101 may further send the network topology of the current network to the database server 105, and the database server 105 stores the network topology of the current network and sends the stored network topology to the front-end display server for display.
Optionally, in the embodiment of the present invention, the database server 105 may store the generated time sequence of the network topology, and display the generated time sequence, so that a user can quickly check whether there is a topology change in the current network, and the network maintenance is facilitated.
