Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

In order to solve the problem that the server cannot correctly identify terminals with multiple IP addresses, an embodiment of the present invention provides a method for terminal identification, which focuses on the terminal side and can ensure the accuracy of terminal identification by the server. As shown in Figure 1, the method includes:

101. Scan the local network card to generate a network card address list.

When terminals connect to the network, in order to realize mutual communication, they will communicate and connect according to the Internet Protocol (IP for short) between computer networks. Usually, the IP address is unique, so that the server can communicate with the terminal according to the IP address. identify.

When the terminal is connected to the network, it is realized through a network interface board or network interface card (network card for short) inside the terminal. The network card is a network component that works at the link layer. It is the interface connecting the terminal and the transmission medium in the network. It can not only realize the physical connection and electrical signal matching with the network transmission medium, but also involve medium access control, data encoding and decoding. And the function of data caching, etc.

When the terminal connects to the network through the network card, it usually needs to set the properties of the network card. For example, change the name of "Local Connection 1" to "Control Network A" to connect to Control Network A, and its properties are set as follows: IP address: 128.128.1.X (X is a value within the limited range of the operating node address); Rename "Local Connection 2" to "Control Network B", which is used to connect to Control Network B, and its properties are set as follows: IP address: 128.128.2.X (X is a value within the limited range of the operating node address).

Since different network cards usually have their own IP addresses, when determining the IP address of the terminal, the embodiment of the present invention first needs to perform step 101 to scan the local network card to generate a list of network card addresses. Protocol IP address.

102. Deleting the IP address of the virtual network card from the network card address list.

With the development of Internet hardware, the types of network cards that can be used for terminal networking are also diverse. Therefore, after step 101 is executed, the terminal may scan out multiple types of network cards, and the generated network card address list will contain multiple different IP addresses.

Among different types of network cards, a special network card is a virtual network card. Virtual network card, also known as virtual network adapter, uses software to simulate the network environment and simulate the network adapter. The virtual network card is mainly to establish a local area network between remote computers. Since the virtual network card can simulate the hub function, the terminal recognizes this software as a network card, and accesses the external network through the virtual network card or connects to the virtual hub to form a local area network with other terminals.

Since the virtual network card is essentially a piece of software installed in the terminal, it can be installed and uninstalled as needed. At the same time, when the server or network is restarted, the virtual network card will obtain a reassigned IP address, so the IP address of the virtual network card cannot be used as a server. The basis for identifying the terminal.

103. For the remaining network cards, respectively bind the IP address of each network card to the server to perform a communication test.

After removing the IP address of the virtual network card in the network card address list, in order to determine the actual IP address that can be connected to the server, the terminal can perform step 103 to bind the remaining IP addresses of each network card to the server for communication testing. After setting the properties of the local connection for the remaining network cards, the terminal needs to check whether each network card is working normally, that is, connect each network card to the network in turn to check whether the terminal can use the network card to connect normally.

In the embodiment of the present invention, as an optional implementation, the terminal can send a return request packet to the server on the network side through the network card respectively, asking the server to give a reply after receiving the request, so as to determine the response time of the network and whether the terminal Connect with the network. If the terminal does not receive a reply from the server on the network side after sending the echo request packet, the configuration of the network card is incorrect, causing the server not to allow incoming response requests, and the IP address of the network card cannot be used as the actual IP address of the terminal. The success of sending the echo request packet only guarantees that there is a connected physical path between the terminal and the server.

104. Determine the IP address of the network card successfully communicating with the server as the actual IP address of the terminal.

When the terminal sends a echo request packet to the server on the network side to determine whether the terminal is connected to the network, although the success of sending the echo request packet can only ensure that there is a physical path between the terminal and the server, there is a type of network card (mobile WiFi) can be connected to a wired network to convert wireless signals in a bridging manner by plugging it into a networkable terminal; or form a mobile WiFi receiving and transmitting signal source through a wireless Internet access chip (sim card) provided by a wireless operator , through this set of equipment can be connected to the network. When a terminal uses mobile WiFi to connect to the Internet, in order not to affect the normal networking of other terminals, it usually uses a fixed IP address. As shown in Figure 2, select "Use the following IP address" in the figure and set the IP address by yourself, as long as it is different from the IP address of other terminals. If the terminal is connected to the network through a wired network card, the IP address of the wired network card can be used as the actual IP address of the terminal; if the terminal is connected to the network through mobile WiFi, the IP address of the mobile WiFi can be used as the actual IP address of the terminal.

105. Report the actual IP address to the server.

After the terminal determines the actual IP address, it reports the actual IP address to the server, and the server will accurately identify the terminal according to the actual IP address of the terminal.

The terminal identification method provided by the embodiment of the present invention can scan the local network card of the terminal, and generate a network card address list recording the Internet protocol IP addresses corresponding to different network cards. After removing the virtual network card IP address in the network card address list, Bind the IP address of each of the remaining network cards to the server for a communication test, and report the IP address of the successfully communicated network card as the actual IP address of the terminal to the server, so that the server can identify the terminal based on the actual IP address. Compared with the prior art, the present invention is based on binding the IP address to communicate with the server, which can eliminate the interference of IP address confusion caused by the existence of different network cards in the terminal, and determine the IP address successfully interconnected with the server as the actual IP address of the terminal. The address ensures the accuracy of the server's identification of the terminal.

In order to better understand the above-mentioned method shown in FIG. 1 , as a refinement and extension of the above-mentioned implementation manner, the embodiment of the present invention will describe the steps in FIG. 1 in detail.

Usually, the terminals in the LAN environment used for work have wired network cards and are connected to the local area network through the wired network cards. They can also be connected to the local area network through mobile network cards such as portable WiFi or virtual network cards. Especially when a terminal such as a notebook computer is connected to the local area network, in addition to being connected to the local area network through a wired network card, a mobile network card such as a portable WiFi or a virtual network card, the notebook computer also has a wireless network card. Access point (Access Point, referred to as wireless AP) coverage, you can connect to a wireless network through a wireless network card in a wireless manner. Therefore, when scanning the local network card in step 101, the terminal usually scans whether there are wired network cards, wireless network cards, mobile network cards and virtual network cards locally, wherein the mobile network card is usually a portable wireless fidelity device WiFi.

After the terminal scans the local network card and generates the network card address list, in the process of removing the IP address of the virtual network card from the network card address list in step 102, based on the characteristics of the above-mentioned virtual network card, as an optional implementation mode of the embodiment of the present invention , the terminal can judge the type of the network card according to the value of the Characteristics item in the operating system when distinguishing the type of the network card. For example, the Characteristics item can consist of the following hexadecimal values and descriptions: ox1NCF_VIRTUAL indicates that the component is a virtual adapter, ox2NCF_SOFTWARE_ENUMERATED indicates that the component is a software-emulated adapter, and ox4NCF_PHYSICAL indicates that the component is a physical adapter. In short, the terminal can determine whether the network card is a virtual network card or a physical network card only by judging the value of the Characteristics item. If it is a virtual network card: Characteristics&NCF_VIRTUAL==NCF_VIRTUAL; if it is a physical network card: Characteristics&NCF_PHYSICAL==NCF_PHYSICAL.

When the terminal determines the virtual network card in the network card address list and removes the virtual network card, in step 103, for the remaining network cards, respectively bind the IP address of each network card to the server for communication test, as a kind of In an optional implementation manner, the IP address of each remaining network card may be bound in an HTTP data packet to perform a communication test with the server. When the terminal performs a communication test by sending an HTTP packet to the server, what the terminal actually sends is an HTTP request message. The format of the HTTP request message is shown in Figure 3, where the IP address is bound to the HTTP request message. The location of the address field of the IP header. After completing the binding of the IP address and the HTTP request message, the terminal initiates a Connect connection request to the server, reports the bound HTTP request message, and waits for a response from the server.

Of course, the terminal can also send an IP message to the server to perform communication detection with the server. As shown in Figure 4, the terminal writes the IP addresses of each network card into the source IP address in the IP message according to the format of the IP message. Send it to the server to check whether the communication with the server is successful.

When the terminal sends an HTTP request message or IP message written to the IP address of the network card to the server, if a certain message sent receives a response from the server within the preset time period, it means that the terminal writes the IP address in the message to the server. If the communication between the IP address and the server is successful, the IP address written in the message can be determined as the actual IP address of the terminal.

Further, the embodiment of the present invention also provides an optional implementation mode, which is used for if the terminal determines that there are multiple IP addresses that can communicate successfully by sending a message to the server, when the multiple IP addresses that have successfully communicated Before determining the actual IP address of the terminal, it is checked whether the IP address successfully communicating with the server has a corresponding gateway, and the IP address without a corresponding gateway usually communicates with the server through bridging.

Since a terminal usually has only one default gateway, when the terminal detects that the IP address with a successful communication has a corresponding gateway, it determines the IP address with the corresponding gateway as the actual IP address of the terminal. Of course, due to the complexity of the terminal settings or the network environment it is in, sometimes the gateway may not be detected in all the IP addresses with successful communication. At this time, the terminal can select an IP address from these IP addresses with successful communication to determine It is the actual IP address of the terminal, and the actual IP address will be sent to the server as the preferred IP address and other successful IP addresses for storage, and the server will use the actual IP address as the default IP address to identify the terminal.

As an application scenario of the foregoing embodiment, a terminal is taken as an example for description. The terminal itself is installed with a wired network card NIC1 , a wireless network card NIC2 and a virtual network card NIC3 , in addition to a mobile WiFi inserted into the terminal. Since there are four types of network cards in the terminal, when the terminal scans a local network card, it will generate a list of network card addresses including four IP addresses, as shown in FIG. 5 . Among the IP addresses in FIG. 5 , the wired network card NIC1 corresponds to IP1, the wireless network card NIC2 corresponds to IP2, the virtual network card NIC3 corresponds to IP3, and the mobile WiFi corresponds to IP4. Among them, since the virtual network card NIC3 is essentially a kind of software, its IP address cannot be used to identify the terminal, and needs to be removed from the network card address list by the terminal. The IP address of network card NIC1, wireless network card NIC2 and mobile WiFi can also achieve the same effect of eliminating virtual network card NIC3.

When IP1, IP2, and IP4 are selected in the network card address list, the terminal binds IP1, IP2, and IP4 to the position of the IP header address field in the HTTP data packet, and sends the IP address to the server respectively. HTTP packets, waiting for the server's response. Usually in the actual environment, the wired network card NIC1 and the wireless network card NIC2 do not use the same network, and the IP2 address corresponding to the wireless network card NIC2 cannot successfully communicate with the server, while the mobile WiFi can be bridged on the link of the wired network card to achieve communication with the server. Communication, so the IP addresses of successful communication are IP1 and IP4, which can be sent to the server as the actual IP address of the terminal. However, the successful communication with the server using the IP4 address is actually realized on the wired network card NIC1 through the mobile WiFi bridge, so further, the terminal can also detect whether IP1 and IP4 correspond to a gateway, because a terminal usually only has one default Gateway, when the terminal detects that IP1 corresponds to a gateway, it can send IP1 as the actual IP address of the terminal to the server; of course, the terminal may not detect that IP1 and IP4 have corresponding gateways, at this time, the terminal can choose randomly IP1 or IP4 is used as the actual IP address. When the terminal selects IP1 as the actual IP address, IP1 is preferred and sent together with IP4 to the server for storage. The server will use IP1 as the default IP address to identify the terminal.

In the embodiment of the present invention, after determining the IP address for successful communication between the terminal and the server, it is further detected whether it corresponds to a gateway, and the IP address corresponding to the gateway is determined as the actual IP address of the terminal, and the server can communicate with the terminal through such an actual IP address for more accurate identification.

Further, as an implementation of the method shown in FIG. 1 above, an embodiment of the present invention also provides a device for identifying a terminal.

Further, the device also includes:

The detecting unit 66 is configured to detect whether the IP address successfully communicating with the server has a corresponding gateway before the determining unit 64 determines the IP address successfully communicating with the server as the actual IP address of the terminal;
