The intelligent terminal comprises an intelligent terminal, a switch, a port and a power supply, wherein the switch is connected with the switch through the port; in particular, a plurality of connection ports may be included on a switch to enable information to be transmitted indefinitely across a limited number of switches.

In this embodiment, optionally, the connection information of the target device includes an association relationship between an IP address and a device MAC address, an association relationship between a port number and a port MAC address, and a port connection link of an adjacent target device.
If the target device is a switch, one switch has an IP address, a Media Access Control (MAC) address (i.e., a physical address), a plurality of ports, and one port corresponds to one MAC address; if the target equipment is an intelligent terminal, one intelligent terminal has one IP address, one IP address corresponds to one equipment MAC address, and if the intelligent terminal has no port, the intelligent terminal has no corresponding port MAC address.

S220, establishing an equipment initial connection link between every two target equipment in the range of the target network according to the port connection links of the adjacent target equipment.
In this embodiment, the device initial connection link is a connection link formed by all target devices within the range of the target network; since the initial connection link of the device is obtained by connecting all target devices as initial connection devices, there may be information loss or information redundancy in the initial connection link of the device, and further processing is required.

Table 3 second storage set storage table
In table 3, the device MAC corresponding to the port number is a device MAC address where the port number of the device can reach the device; sw1A and sw1B are respectively an A port and a B port of sw 1; sw2A and sw2B are respectively an A port and a B port of sw 2; sw3A and sw3B are the A port and B port of sw3, respectively.
S240, determining a port connection link between at least two switches according to the initial connection link of the equipment and the first storage set; and determining a connection link between the switch and the intelligent terminal according to the initial connection link of the equipment, the first storage set and the second storage set.
In this embodiment, a port connection link between two switches is a link connected between two switches through a port; the connection link between the switch and the intelligent terminal is a link for connecting a port of the switch and the intelligent terminal; specifically, the intelligent terminal in this embodiment may be a computer.
In this embodiment, the connection information of the target devices is classified and stored in the corresponding sets, and the connection links between the target devices are effectively determined according to the unique matching between different pieces of information stored in the sets.
And S250, determining a topological structure within the range of the target network according to the port connection link between at least two switches and the connection link between the switch and the intelligent terminal.
On the basis of the foregoing embodiment, optionally, the obtaining of the connection information of the target device in the target network range includes:
acquiring an IP address of target equipment within a target network range;
and determining the connection information of the target equipment according to the IP address of the target equipment based on the network management protocol.
In this embodiment, determining the connection information of the target device according to the IP address of the target device based on the network management protocol may include: traversing all the IP addresses of the target devices in the range of the target network, and obtaining the MIB (i.e., connection information in this embodiment) of the IP address through a network management protocol, such as SNMP; if the relevant information of the IP address cannot be obtained, the IP address is not reachable, and the IP address is discarded. The method can directly acquire the effective connection information of the target equipment.
On the basis of the foregoing embodiment, optionally, determining a port connection link between at least two switches according to the device initial connection link and the first storage set includes:
determining a port MAC address of initial connection equipment in an initial connection link according to the incidence relation between the port number and the port MAC address, and searching an IP address of termination equipment in the initial connection link of the equipment from a first storage set so as to complete information of the initial connection link of the equipment and obtain a complete connection link of the equipment;
and carrying out link deduplication processing on the equipment completion connection link to obtain a port connection link between at least two switches.
In this embodiment, since the initial connection link table of the device lacks the MAC address of the port of the initial connection device and the IP address of the terminating connection device, information completion needs to be performed on the initial connection link of the device, and the completed device completed connection link may be referred to in table 4 below.
TABLE 4 complete connection link table for equipment
It can be seen that there are two duplicate links in table 4, i.e., there are two connection links with port number sw1A and port number sw 2A; namely, two connection links with port numbers sw1B and sw3A are provided; removing any link in the repeated links, and reserving one link; the complexity of the link can be effectively simplified to ensure the unique connectivity of the link.
The port connection links between the switches can be seen in table 5 below.
TABLE 5 Port connection links between switches
| start IP | 192.168.1.1 | 192.168.1.1 |
| start Port | sw1A | sw1B |
| start Mac | sw1MacA | sw1MacB |
| end IP | 192.168.1.2 | 192.168.1.3 |
| end Port | sw2A | sw3A |
| end Mac | sw2MacA | sw3MacA |

and determining a connection link between the switch and the intelligent terminal according to the third storage set and the fourth storage set.
In this embodiment, it can be seen from table 5 that there are two connection links, the initial connection device is switch 1, and the terminating connection devices are switch 2 and switch 3, respectively. The third storage set obtained by the deletion operation can be referred to table 6; the fourth storage set can be seen in table 7.
Table 6 third memory set table
| IP address | Device MAC address |
| 192.168.1.4 | com1 |
| 192.168.1.5 | com2 |
TABLE 7 fourth storage set Table
| Port number | Device MAC address |
| sw2B | com1 |
| sw3B | com2 |

Then, the intelligent terminal 1 can be connected with the port B of the switch 2; the intelligent terminal 2 is connected with the B port of the switch 3.
Through the operation, the connection link between the intelligent terminal and the port of the switch can be rapidly screened out by the embodiment.
