detailed description

Referring to FIG. 1 , it is an application environment diagram of a preferred embodiment of the network device discovery system 10 of the present invention. The network device discovery system 10 is applied to the cloud server 1 . The cloud server 1 is connected to network devices in different network segments through the cloud network 2 . For example, FIG. 1 shows that network segment A includes multiple network devices a1-an, and network segment B includes multiple network devices b1-bn. The network devices a1-an of the network segment A are connected to the cloud network 2 through a network address translation (NAT) device 3 , and the network devices b1-bn of the network segment B are connected to the cloud network 2 through a NAT device 4 . The network device may be a network camera or other electronic devices.

NAT devices (such as NAT devices 3 and 4) are mainly used to realize the conversion of private IP addresses into public IP addresses. The private IP address refers to the IP address of the internal network or host, and the public IP address refers to the globally unique IP address on the Internet. For example, network devices a1 and a2 in network segment A have private IP addresses D1 and D2 respectively in network segment A. After receiving data packets sent from network devices a1 and a2 to cloud network 2, NAT device 3 will send the data packets to The recorded private IP address D1 or D2 is converted into the public IP address M1 of the network segment A to the external network, and the private IP address D1 or D2 of the network device a1 or a2 sending the data packet is recorded at the same time.

Network administrators can view the network devices they manage by logging into the management client. For example, the network administrator in FIG. 1 can log in to the management client 5 in network segment A, or log in to the management client 6 in network segment B. Through permission settings, network administrators can manage network devices in different network segments. For example, the network administrator U1 can manage the network devices a1 - a5 in the network segment A and the network devices b8 - b12 in the network segment B.

Referring to FIG. 2 , it is a functional block diagram of a preferred embodiment of the network device discovery system 10 of the present invention. The network device discovery system 10 includes a first receiving module 11 , an information recording module 12 , a second receiving module 13 , a first searching module 14 , a second searching module 15 and a recommending module 16 . Using these functional modules, the network device discovery system 10 stores information of all network devices connected to the cloud network 2 in the management list 20 . The management list 20 creates a record for each network device, recording the network device's device identification information (Device ID), the used public IP address and its management status. The management status refers to whether a network device is included in the management scope of a network administrator. If the management status is included in the management scope of the network administrator, the management status also includes the identification information (Owner ID) of the network administrator.

Each network device includes an information update module, for example, the network device 7 shown in FIG. 2 includes an information update module 70 . The information updating module 70 is used for registering the information of the network device 7 with the cloud server 1 when the network device 7 accesses the cloud network 2, and for changing or accepting the information of the network device 7 (such as the public IP address it uses) to the cloud server 1. When the pipe status changes, the cloud server 1 is requested to update the information of the network device 7 recorded in the management list 20 .

Afterwards, when the network device discovery system 10 receives a network administrator's request from a management client (such as the management client 5) to search for network devices, the network administrator is managed according to the information recorded in the management list 20. All network devices are fed back to the network administrator, and an unmanaged network device having the same public IP address as the network device managed by the network administrator is found out and recommended to the network administrator.

The modules 11-16 include computer programming instructions, and these computer programming instructions and the management list 20 are stored in the storage device of the cloud server 1, and the processing device of the cloud server 1 executes these computer programming instructions to provide network device searching system 10. the above functions. The functions of the modules 11-16 will be described in detail below in conjunction with FIG. 3 .

Referring to FIG. 3 , it is a flow chart of a preferred embodiment of the network device discovery method of the present invention.

Step S10, the first receiving module 11 receives the registration information of the network device, the registration information includes the device identification information (Device ID) and the public IP address of the network device.

In step S20 , the information recording module 12 creates a management list 20 , and records information and management status of registered network devices in the management list 20 . As mentioned above, the management list 20 creates a record for each network device, recording the device identification information (Device ID), the public IP address used and the management status of the network device. The management status refers to whether a network device is included in the management scope of a network administrator. If the management status is included in the management scope of the network administrator, the management status also includes the identification information (Owner ID) of the network administrator.

In step S30, the second receiving module 13 receives a request from the network administrator to search for network devices sent from the management client. For example, assuming that the network administrator U1 logs in to the management client 5, the network administrator U1 can use the management client 5 to find out all the network devices in the network segment A to which the management client 5 belongs, but the management client 5 cannot find the devices in other network segments. network device. At this point, the management client 5 can send a request to the cloud server 1 .

In step S40, the first search module 14 searches the management list 20 for all network devices managed by the network administrator according to the network administrator's identification information. For example, the first search module 14 finds out from the management list 20 that the network devices managed by the network administrator U1 include the network devices a1 - a5 in the network segment A and the network devices b8 - b12 in the network segment B. The first search module 14 can feed back all the found network devices managed by the network administrator in a list form to the management client 5 logged in by the network administrator U1 for display. In other embodiments, the first search module 14 can feed back all the network devices managed by the network administrator found in other ways, such as charts, tables, etc., to the management client 5 logged in by the network administrator U1 for display. .

Step S50, the second search module 15 searches the management list 20 for a network device with the same public IP address according to the found public IP address of the network device. For example, assuming step S40 finds that the network devices a1-a5 have the same public IP address M1, and the network devices b8-b12 have the same public IP address M2, then the second search module 15 searches the management list 20 for the public IP address Other network devices that are M1 or M2 may find network devices a8-a10, b8-b12.

In step S60, the recommending module 16 recommends the found network devices that are not managed by any network administrator to the network administrator who sent the request. For example, assuming that the found device a10 of the network devices a8-a10 has been brought into the management range by the network administrator U2, and the found device b8 of the network devices b8-b12 has been brought into the management range by the network manager U2, then the recommendation module 16 After removing a10 and b8, recommend a8-a9 and b9-b12 to the network administrator U1. The recommended method can be to pop up a prompt window on the management client 5 logged in by the network administrator U1, prompting "a network device that is not under management is found, do you want to automatically include the following device **** into the management range?" Network Management User U1 can ignore the recommendation information, or click the "Confirm" button in the prompt window to bring the recommended network device into his own management scope. In other embodiments, the recommended method can also be in the form of pushing a file to the management client 5 logged in by the network administrator U1, and the pushed file records the network devices found that are not managed by any network administrator Information.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation, although the present invention has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the present invention can be The technical solution shall be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present invention.
