Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.

In order to realize automatic display of a networking topology, the embodiment of the invention provides a networking topology display method and device, electronic equipment and a machine-readable storage medium. Next, a description is first given of a networking topology display method provided in an embodiment of the present invention.

The networking topology structure display method provided by the embodiment of the invention can be applied to electronic equipment with an image display function, and the electronic equipment also has core processing capability. The method for displaying the networking topology structure provided by the embodiment of the invention can be realized by at least one of software, hardware circuits and logic circuits arranged in the electronic equipment.

As shown in fig. 1, a method for showing a networking topology provided by an embodiment of the present invention may include the following steps.

S101, sending a query message to equipment in networking, wherein the equipment in networking comprises terminal equipment and transmission equipment.

The networking mentioned in the embodiment of the present invention may be any network environment, such as a security networking, an enterprise network, a campus network, and the like, where an electronic Device for displaying a networking topology actively sends a query message to a Device in the networking when there is a need to display the networking topology (for example, when a manager clicks a display button on an interface of the electronic Device, or when an iVMS 4200 client is installed on the electronic Device and logs in the client), where the query message may be a query message of a general Protocol, such as a TCP (Transmission Control Protocol )/IP (Internet Protocol), or a query message of a private Protocol, such as an SADP (Search Active Device Protocol) query message.

The electronic device may send the query message in a multicast/broadcast manner, etc. If the inquiry message of the private protocol is sent in a multicast mode, the devices supported by the private protocol are added into the multicast group before the inquiry message is sent, so that the devices supported by the private protocol in the networking can receive the inquiry message and respond to the inquiry message after the inquiry message is multicast.

The electronic device may send the query message periodically (for example, every 60s), so that it can be known whether the devices in the networking are added, reduced or replaced in time even if the change of the devices in the networking is dealt with.

The electronic equipment can send query messages to all the equipment in the networking; or sending query messages to the connected devices, and then forwarding the query messages to other devices by the devices; it is also possible to send query messages to certain specific types of devices, which forward the query messages to other devices.

S102, receiving neighbor information fed back by the first transmission device, wherein the neighbor information includes port information of each port of the first transmission device and identification information of devices connected to each port corresponding to the port information of each port, and the first transmission device is any transmission device in the network.

After receiving the query message, a transmission device (e.g., a switch, a router, a wireless bridge, a fiber transceiver, etc.) in the networking collects neighbor information of a local port, that is, which port is connected to a device having which identification information, the neighbor information of the transmission device may be detected by the transmission device, and the identification information may be information capable of uniquely representing one device, such as a Media Access Control (MAC) address, a serial number, and an IP address.

After receiving the query message, the terminal device usually responds to the query message and feeds back device information (such as a device model, a serial number, an MAC address, an IP address, and the like) of the terminal device to the electronic device, the transmission device may intercept information fed back by the transmission device and the terminal device connected to the transmission device, extract identification information from the information, record port information of the intercepted information, store the information locally, and then form a piece of neighbor information by the port information and the corresponding identification information and feed back the neighbor information to the electronic device.

When the terminal device and the transmission device respond to the query message, the terminal device and the transmission device may respond by sending a response message, where the response message carries device information of the terminal device and neighbor information of the transmission device. The neighbor information of the transmission device may be specifically in the form of a neighbor mapping table, where a corresponding relationship between a port and identification information is recorded in the neighbor mapping table, as shown in table 1, a first column of the neighbor mapping table is a port number, a second column is a MAC address, and a third column is a serial number.

TABLE 1

Port(s)	MAC address	Serial number
			1	00-11-22-33-44-55	XXXXXX
1	00-22-33-44-55-66	YYYYYY

S103, determining and displaying a networking topological structure according to the neighbor information and the device type corresponding to the acquired identification information of each device.

After the electronic device receives the neighbor information fed back by each transmission device, because the neighbor information represents the corresponding relationship between the port of the transmission device and the identification information of the device connected to the port, the electronic device can know which identification information devices are connected under the port of one transmission device based on the neighbor information, and then can determine what types of devices are connected under the port of one transmission device according to the device types corresponding to the identification information of each device. Therefore, the topological structure of the networking can be determined and displayed.

Optionally, the obtaining manner of the device type may specifically be: and receiving the equipment information fed back by the equipment, wherein the equipment information comprises the equipment type and the identification information.

After receiving the query message, the terminal device responds to the query message and feeds back device information (including device type and identification information) of the terminal device to the electronic device, and after receiving the response of the terminal device, the electronic device can acquire the device type corresponding to the identification information of each device.

Of course, the device information of each device may also be set in advance on the electronic device, or the device information may be reported together with the neighbor information after the transmission device acquires the device information fed back by the terminal device.

By applying the embodiment of the invention, the inquiry message is sent to the equipment in the networking, the neighbor information fed back by any transmission equipment in the networking is received, and the topological structure of the networking is determined and displayed according to the neighbor information and the equipment type corresponding to the identification information of the equipment in the acquired neighbor information. The electronic device for displaying the networking topological structure actively sends a query message to the devices in the networking, the devices in the networking respond to the query message, and when any transmission device responds to the query message, the fed-back neighbor information comprises port information of each port and identification information of the devices connected with each port corresponding to the port information of each port, namely the neighbor information fed back by the transmission device comprises the connection relation of the transmission device and other devices in the networking, so that the networking topological structure can be learned according to the neighbor information of the transmission device and the device type corresponding to the identification information of each device. By utilizing the embodiment of the invention, the design of technical personnel for networking is not needed to be known in advance, but the networking topological structure is learned in real time, so that the networking topological structure can be automatically displayed.

The specific implementation of each step in the example shown in fig. 1 is described in more detail below.

In an implementation manner of the embodiment of the present invention, S103 may be specifically implemented by the following steps:

the method comprises the steps of firstly, judging whether port information of a first port in neighbor information only corresponds to identification information of one device, wherein the first port is any one port of a first transmission device.

And step two, if not, determining the connection relation between the plurality of devices and the first transmission device according to the identification information of the plurality of devices corresponding to the port information of the first port and the device type corresponding to the identification information of each device in the plurality of devices.

And thirdly, displaying the connection relation between the plurality of devices and the first transmission device.

When learning of a networking topology structure is performed, connection relationships between transmission devices and other devices can be learned one by one, taking a first transmission device as an example, if port information of a first port in neighbor information of the first transmission device corresponds to identification information of a plurality of devices, it is indicated that the plurality of devices are connected under the first port, and generally, only one device is connected under one port, and if the port device of the first port corresponds to the identification information of the plurality of devices, it is indicated that tree-shaped connection of the plurality of devices exists under the first port, so that the connection relationships between the plurality of devices and the first transmission device, specifically, which devices are connected under the first port of the first transmission device, need to be determined according to the identification information of the plurality of devices corresponding to the port information of the first port and the obtained device types corresponding to the identification information of each device in the plurality of devices, which in turn is directly connected to the first transmission device.

If one transmission device is a transmission device whose port information corresponds to the identification information of one terminal device, it indicates that the transmission device is directly connected with the terminal device, and if the device identifications of multiple devices corresponding to the port information of the first port of one transmission device include both the identification information of at least one transmission device and the identification information of at least one terminal device, it indicates that the transmission device is a higher-layer transmission device. After the connection relationship between the first transmission device and the plurality of devices is learned, the connection relationship may be displayed.

In an implementation manner of the embodiment of the present invention, the second step may specifically be: if the identification information of the multiple devices corresponding to the port information of the first port is determined to be the identification information of the terminal device according to the identification information of the multiple devices corresponding to the port information of the first port and the device type corresponding to the identification information of each device in the multiple devices, it is determined that an unknown transmission device is connected between the first transmission device and the multiple terminal devices.

Correspondingly, the third step may be: and displaying the connection relation of the first transmission equipment connected with the unknown transmission equipment and the unknown transmission equipment connected with the plurality of terminal equipment.

If the identification information of the plurality of devices corresponding to the port information of the first port is identified, it is found that the port information of the first port corresponds to the identification information of the terminal device, and there is no identification information of any transmission device.

When the display is performed, the unknown transmission device can be displayed as a virtual transmission device, and the connection relationship between the first transmission device and the unknown transmission device, and the connection relationship between the unknown transmission device and the plurality of terminal devices can be displayed.

For example, the identification information of the device corresponding to the port 1 in the neighbor information fed back by the transmission device 1 includes: the MAC address of terminal a, the MAC address of terminal B, the MAC address of terminal C and the MAC address of terminal D. Then, it may be determined that an unknown transmission device is connected between the transmission device 1 and the terminal device a, the terminal device B, the terminal device C, and the terminal device D, and the connection relationship is as follows: the transmission device 1 is connected with unknown transmission devices, the unknown transmission devices are connected with the terminal device a, the terminal device B, the terminal device C and the terminal device D, and the corresponding display effect is shown in fig. 2.

In another implementation manner of the embodiment of the present invention, the second step may specifically be: if the identification information of the plurality of devices corresponding to the port information of the first port comprises the identification information of at least one transmission device according to the identification information of the plurality of devices corresponding to the port information of the first port and the obtained device type corresponding to the identification information of each device in the plurality of devices, reading neighbor information of a second transmission device, wherein the second transmission device is any one of the at least one transmission device; judging whether the intersection of identification information corresponding to port information of a second port and identification information corresponding to port information of a first port in neighbor information of second transmission equipment is empty or not, wherein the identification information of a plurality of pieces of equipment corresponding to the port information of the second port comprises the identification information of the first transmission equipment; and if the intersection is empty, determining that the first transmission equipment and the second transmission equipment are in a direct connection relation.

Correspondingly, the third step may be: and displaying the connection relation of the first transmission equipment directly connected with the second transmission equipment.

If the identification information of the multiple devices corresponding to the port information of the first port is identified, and the identification information of the multiple devices corresponding to the port information of the first port is found to include the identification information of at least one transmission device, it is required to determine whether an intersection of the identification information corresponding to the port information of the second port in the neighbor information of a second transmission device in the at least one transmission device and the identification information corresponding to the port information of the first port is empty, if the intersection is empty, it is indicated that no other device is connected between the first transmission device and the second transmission device, the first transmission device and the second transmission device are directly connected, the identification information of the multiple devices corresponding to the port information of the second port includes the identification information of the first transmission device, the port information of the first port corresponds to the identification information of the second transmission device, and the port information of the second port corresponds to the identification information of the first transmission device, and then, whether the first transmission equipment is directly connected with the second transmission equipment or not can be judged by judging whether the intersection of the identification information corresponding to the port information of the second port and the identification information corresponding to the port information of the first port is empty or not.

When the display is performed, the directly connected connection relationship between the first transmission device and the second transmission device can be displayed.

For example, the identification information of the device corresponding to the port 1 in the neighbor information fed back by the transmission device 1 includes: the MAC address of the transmission device 2, the MAC address of the transmission device 3, the MAC address of the terminal device a, the MAC address of the terminal device B, the MAC address of the terminal device C and the MAC address of the terminal device D. The identification information of the device corresponding to the port 1 in the neighbor information fed back by the transmission device 2 includes: the MAC address of the transmission device 1 and the identification information of the device corresponding to the port 2 include: the MAC address of the transmission device 3, the MAC address of terminal device a, the MAC address of terminal device B, the MAC address of terminal device C and the MAC address of terminal device D. The identification information of the device corresponding to the port 1 in the neighbor information fed back by the transmission device 3 includes: the MAC address of the transmission device 1 and the MAC address of the transmission device 2, the identification information of the device corresponding to the port 2 is the MAC address of the terminal device a, the identification information of the device corresponding to the port 3 is the MAC address of the terminal device B, the identification information of the device corresponding to the port 4 is the MAC address of the terminal device C, and the identification information of the device corresponding to the port 5 is the MAC address of the terminal device D.

By comparison, the intersection of the identification information of the device corresponding to the port 1 in the neighbor information of the transmission device 1 and the identification information of the device corresponding to the port 1 in the neighbor information of the transmission device 2 is empty, and the intersection of the identification information of the device corresponding to the port 2 in the neighbor information of the transmission device 2 and the identification information of the device corresponding to the port 1 in the neighbor information of the transmission device 3 is empty. Therefore, it can be determined that the transmission device 1 and the transmission device 2 are directly connected, and the transmission device 2 and the transmission device 3 are directly connected, and the ports 2, 3, 4, and 5 in the transmission device 3 correspond to only the identification information of one terminal device, so that the transmission device 3 and the terminal device A, B, C, D are directly connected, and the corresponding display effect is as shown in fig. 3.

In another implementation manner of the embodiment of the present invention, the second step may specifically be: if the identification information of the plurality of devices corresponding to the port information of the first port comprises the identification information of at least one transmission device according to the identification information of the plurality of devices corresponding to the port information of the first port and the obtained device type corresponding to the identification information of each device in the plurality of devices, reading neighbor information of a second transmission device, wherein the second transmission device is any one of the at least one transmission device; judging whether the intersection of identification information corresponding to port information of a second port and identification information corresponding to port information of a first port in neighbor information of second transmission equipment is empty or not, wherein the identification information of a plurality of pieces of equipment corresponding to the port information of the second port comprises the identification information of the first transmission equipment; and if the intersection is not empty, determining that an unknown transmission device is connected between the first transmission device and at least one transmission device.

Correspondingly, the third step may be: and displaying the connection relation of the first transmission equipment connected with the unknown transmission equipment and the unknown transmission equipment connected with at least one transmission.

If the identification information of the multiple devices corresponding to the port information of the first port is identified, and the identification information of the multiple devices corresponding to the port information of the first port is found to include the identification information of at least one transmission device, it is necessary to determine whether an intersection of the identification information corresponding to the port information of the second port in the neighbor information of the second transmission device in the at least one transmission device and the identification information corresponding to the port information of the first port is empty, and if the intersection is not empty, it is determined that the first transmission device and the second transmission device are not directly connected, and other unknown transmission devices are also connected.

When the display is performed, the unknown transmission device may be displayed as a virtual transmission device, and the connection relationship between the first transmission device and the unknown transmission device, and between the unknown transmission device and at least one transmission device may be displayed.

For example, the identification information of the device corresponding to the port 1 in the neighbor information fed back by the transmission device 1 includes: the MAC address of the transmission device 2, the MAC address of the transmission device 3, the MAC address of the terminal device a, the MAC address of the terminal device B, the MAC address of the terminal device C and the MAC address of the terminal device D. The identification information of the device corresponding to the port 2 in the neighbor information fed back by the transmission device 2 includes: the MAC address of the transmission device 3, the MAC address of terminal device a, the MAC address of terminal device B, the MAC address of terminal device C and the MAC address of terminal device D. In the neighbor information fed back by the transmission device 3, the identification information of the device corresponding to the port 1 is the MAC address of the transmission device 2, the identification information of the device corresponding to the port 2 is the MAC address of the terminal device a, the identification information of the device corresponding to the port 3 is the MAC address of the terminal device B, the identification information of the device corresponding to the port 4 is the MAC address of the terminal device C, and the identification information of the device corresponding to the port 5 is the MAC address of the terminal device D.

By comparison, the intersection of the identification information of the devices corresponding to all ports in the neighbor information of the transmission device 1, the identification information of the devices corresponding to all ports in the neighbor information of the transmission device 2, and the identification information of the devices corresponding to all ports in the neighbor information of the transmission device 3 is not empty. And the intersection of the identification information of the device corresponding to the port 2 in the neighbor information of the transmission device 2 and the identification information of the device corresponding to the port 1 in the neighbor information of the transmission device 3 is empty, so that it can be determined that the transmission device 2 is directly connected with the transmission device 3, an unknown transmission device is connected between the transmission device 1 and the transmission device 2, and the ports 2, 3, 4, and 5 in the transmission device 3 are respectively only the identification information of one terminal device, so that the transmission device 3 is directly connected with the terminal device A, B, C, D, and the corresponding display effect is as shown in fig. 4.

In another implementation manner of the embodiment of the present invention, after the first step, the method provided in the embodiment of the present invention may further perform: if the port information of the first port in the neighbor information of the first transmission device only corresponds to the identification information of one device, determining that the device and the first transmission device are in a direct connection relationship according to the identification information of the device corresponding to the port information of the first port and the obtained device type corresponding to the identification information of the device; and displaying the connection relation of the equipment directly connected with the first transmission equipment.

Since generally, only one port of one transmission device is connected to one device, if port information of a first port in neighbor information of a first transmission device only corresponds to identification information of the first device, it is indicated that the first transmission device is directly connected to one device, and based on identification information of a device corresponding to the port information of the first port and a device type corresponding to the acquired identification information of the device, it is possible to determine which type of device the first transmission device is specifically connected to.
