Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
At present, for a scenario in which a security product deployed on a terminal is switched among a plurality of servers, the security product deployed in the terminal in one network area can only be deployed on a fixed server, where the security product includes a security management product, a gateway product, and the like. In the network area a, only the security management product and the gateway product corresponding to the server a can be used, and in the network area B, only the security management product and the gateway product corresponding to the server B can be used. That is, the terminal can only connect with the server in one network area alone and cannot switch to another network area.
In the prior art, if a network area a where a terminal is located is switched to a network area B, security products under the network area B can only be reinstalled on the terminal, so that the terminal is switched to network access control. Such a situation is not advantageous for managing the terminal and at the same time is inconvenient for the user to use the security product.
Therefore, how to implement the handover of the terminal between multiple network areas is a technical problem that needs to be solved at present.
Therefore, the disclosed embodiment provides a network switching method, which is applied to a terminal configured with a plurality of network cards, and comprises the steps of firstly, when a network switching request is received, acquiring a network card address of a target switching network card corresponding to the network switching request; inquiring whether a preset configuration file has a network segment address corresponding to the network card address of the target switching network card; the preset configuration file comprises a corresponding relation between a network segment address and a server address; if the network segment address corresponding to the network card address of the target switching network card exists in the preset configuration file, acquiring a server address corresponding to the network segment address from the preset configuration file; and then, switching the current network card into a target switching network card, and establishing connection with a target server corresponding to the server address through the target switching network card. Therefore, the network switching method provided by the embodiment of the disclosure can realize switching of the terminal among a plurality of network areas.
Based on this, an embodiment of the present disclosure provides a network switching method, which is applied to a terminal configured with multiple network cards, and referring to fig. 1, is a flowchart of the network switching method provided in the embodiment of the present disclosure, and the method includes:
s101, when a network switching request is received, a network card address of a target switching network card corresponding to the network switching request is obtained.
In the embodiment of the disclosure, the terminal is configured with a plurality of network cards, and can establish communication connection with the server in the network area corresponding to the network card through the network card. For example, it may be assumed that a network card a and a network card B are configured in the terminal, where the network card a may access the network area a to implement data transmission with the server a; the network card B can also be accessed into the network area B to realize data transmission with the server B.
In practical applications, different network cards have their corresponding network card addresses (which may be IP addresses), and therefore, when a terminal configures a network card, the terminal sets the IP address of the network card, and so on. Assuming that a network card A and a network card B are configured on the terminal, the IP address of the network card A can be set to be 192.168.1, and the terminal accesses the network area A through the network card A; the IP address of the network card B can be set to 192.168.2, and the terminal accesses the network area B through the network card B.
In the embodiments of the present disclosure, the network handover request is used to handover the current network area to the target network area. And when the terminal receives the network switching request, the network card address of the target switching network card corresponding to the target network area in the network switching request is obtained. For example, when the terminal receives a network switching request for switching from the network area a to the network area B, the terminal acquires a network card address of the network area B corresponding to the network switching request.
In an optional implementation manner, the terminal may determine a target switching network card corresponding to the target switching control by responding to a triggering operation for a target switching control in the at least one switching control, and further, obtain a network card address of the target switching network card.
In practical application, a plurality of switching controls are deployed in a terminal, wherein the switching controls are used for realizing switching of a plurality of network cards in the terminal. When the terminal receives the network switching request, the terminal can respond to the triggering operation of switching the current network card to the target switching control of the target switching network card, and then obtain the network card address of the target switching network card.
In an optional implementation manner, a function of switching multiple network areas can be issued to the terminal through the server system, and multiple switching controls corresponding to the network area switching are configured in the terminal. In practical application, the switching control may be a plurality of icons corresponding to a plurality of network cards configured on the terminal, and when one of the icons is clicked, the network card corresponding to the icon may be switched. For example, the icon corresponding to the network card a is a button for switching to the network area a, and the icon corresponding to the network card B is a button for switching to the network area B. And when the terminal receives the triggering operation aiming at the icon corresponding to the network card A, acquiring the network card address of the network card A. At this time, the icon corresponding to the network card a is the target switching control.
In another optional implementation, only one switching control is deployed in the terminal, and switching of multiple network cards in the terminal can be realized through multiple click operations on the switching control. For example, a network card a, a network card B and a network card C are configured on the terminal, assuming that the network card currently used by the terminal is the network card a, if the network area a where the terminal is located is switched to the network area B or the network area C, and the user clicks the switching control 1 time, the terminal can be switched from the current network card a to the target switching network card B; and the user clicks the switching control 2 times, so that the terminal can be switched from the current network card A to the target switching network card C.
S102, inquiring whether a preset configuration file has a network segment address corresponding to the network card address of the target switching network card.
The preset configuration file comprises the corresponding relation between the network segment address and the server address.
In practical application, when a security product is deployed in a terminal, a preset configuration file is set in the terminal, wherein the preset configuration file comprises network segment addresses corresponding to a plurality of network areas, server addresses and corresponding relations between the network segment addresses and the server addresses.
In the embodiment of the present disclosure, when the terminal obtains the network card address of the target switching network card corresponding to the network switching request, it may be queried whether a network segment address including the network card address of the target switching network card exists in the preset configuration file. Assuming that the network card B is a target switching network card when the terminal receives a trigger operation for a switching icon corresponding to the network card B, after clicking the icon corresponding to the network card B, whether a network segment address including the network card address of the network card B exists in the preset configuration file can be queried to determine whether a network segment address corresponding to the network card address of the network card B exists in the preset configuration file.
S103, if the network segment address corresponding to the network card address of the target switching network card exists in the preset configuration file, the server address corresponding to the network segment address is obtained from the preset configuration file.
In an optional implementation manner, whether a network segment address corresponding to a network card address of a target switching network card exists is inquired from a preset configuration file; and if the network segment address corresponding to the network card address of the target switching network card exists in the preset configuration file, directly acquiring the server address corresponding to the network segment address based on the corresponding relation between the network segment address corresponding to the network card address of the target switching network card in the preset configuration file and the server address.
Assuming that a network area a where a terminal is located is switched to a network area B, at this time, the network card B is a target switching network card, an IP address corresponding to the network card B in the network area B needs to be obtained first, and further, it is determined whether a network segment address corresponding to the IP address of the network card B exists in a preset configuration file, assuming that the IP address of the network card B is 192.168.1.2, if the network segment address corresponding to the IP address of the network card is within 192.168.1.1-255, the IP address of the network card B exists in the network segment address. And according to the corresponding relation between the network segment address and the server address in the pre-configuration file, the server address corresponding to the network segment can be obtained.
In practical application, whether a network segment address corresponding to the network card address of the target switching network card exists or not can be inquired from a preset configuration file; if the network segment address has the network card address of the target switching network card, further confirming the server address corresponding to the network card segment address. The network segment addresses in the preset configuration file need to be matched, when the network segment addresses are successfully matched, the server addresses are continuously matched, and when the server addresses are successfully matched, the server addresses are obtained.
And S104, switching the current network card to a target switching network card, and establishing connection with a target server corresponding to the server address through the target switching network card.
Assuming that the network area A where the terminal is located is switched to the network area B, the network card A is the current network card, the network card B is the target switching network card, and after the server address corresponding to the network card B is obtained, the network card B and the target server B corresponding to the server address can be connected to realize that the terminal is switched from the network card A in the network area A to the network card B in the network area B.
In an optional implementation manner, after the terminal establishes a connection with a target server corresponding to the server address through the target switching network card, the data and the update policy are synchronized from the target server. And after the terminal is switched from the current server to the target server, the terminal synchronizes data in time and receives an updating strategy sent by the target server. Specifically, the terminal synchronizes data information related to the current network card to the target switching network card. After the terminal receives the updating strategy sent by the target server, the local strategy is updated according to the updating strategy message, and synchronization with the strategy on the server is realized, so that the operation resource of the target server is saved, and the experience of a user on network area switching is promoted.
In another optional implementation, if it is determined that the network segment address corresponding to the network card address of the target switching network card does not exist in the preset configuration file, continuing to perform network connection based on the current network card, and displaying a switching prompt message; wherein, the switching prompt message is used for prompting the network switching failure.
Assuming that when the terminal receives a network switching request for switching from the network area a to the network area B, at this time, the network card B is a target switching network card, acquires an IP address corresponding to the network card B, and can query whether a preset configuration file has a corresponding network segment address including the IP address of the network card B, if the preset configuration file does not have the corresponding network segment address corresponding to the IP address of the network card B, a prompt message indicating that switching from the network area a to the network area B fails is displayed in the terminal, that is, the terminal cannot realize switching from the network area a to the network area B, and the terminal continues to perform network connection, data transmission and the like of the network area a based on the current network card a.
The disclosed embodiment provides a network switching method, which is applied to a terminal configured with a plurality of network cards, and comprises the steps of firstly, when a network switching request is received, obtaining a network card address of a target switching network card corresponding to the network switching request; inquiring whether a preset configuration file has a network segment address corresponding to the network card address of the target switching network card; the preset configuration file comprises a corresponding relation between a network segment address and a server address; if the network segment address corresponding to the network card address of the target switching network card exists in the preset configuration file, acquiring a server address corresponding to the network segment address from the preset configuration file; and then, switching the current network card into a target switching network card, and establishing connection with a target server corresponding to the server address through the target switching network card. Therefore, the network switching method provided by the embodiment of the disclosure can realize switching of the terminal among a plurality of network areas.
In order to further understand the network handover method provided by the present disclosure, on the basis of the foregoing embodiments, another network handover method is also provided in the embodiments of the present disclosure, and with reference to fig. 2, a process schematic diagram of a network handover method provided in the embodiments of the present disclosure is shown.
The network switching method of the embodiment of the disclosure can be applied to security products uniformly deployed on a server platform. Among them, security products are classified into 6 main categories, such as endpoint security, network security, application security, data security, identity and access management, and security management. Generally, the security product is generally deployed by using a C/S architecture, and the security product deployed in the terminal can perform functions such as data interaction through communication between the network card and a server corresponding to the network card.
In the embodiment of the disclosure, it is assumed that only a security product under a network area a is installed in a terminal, the terminal is switched from the current network area a to a network area B, the network card B is a target switching network card, when the terminal receives a network switching request for switching from the network area a to the network area B, the terminal acquires a network card address of the network card B corresponding to the network switching request, and then, whether a network segment address corresponding to the network card address of the network card B exists in a preset configuration file is queried.
Assuming that the IP address of the network card B in the terminal is 192.168.1.2, if the network segment address corresponding to the network card IP address is within 192.168.1.1-255, the network segment address has the IP address of the network card B. The terminal can obtain the server address corresponding to the network segment according to the corresponding relation between the network segment address and the server address in the pre-configuration file. After the terminal obtains the server address corresponding to the network card B, the network card B can be connected with the target server B corresponding to the server address, so that the terminal is switched from the network card a in the network area a to the network card B in the network area B. That is to say, the terminal switches the network card a to the network card B, and accesses the network area B through the network card B to realize data transmission with the server B.
In an optional implementation manner, if a network segment address corresponding to the IP address of the network card B does not exist in the preset configuration file, the terminal does not need to switch to the network access environment, or keeps the network card a accessing the network area a, and performs data transmission with the server a through the network card a.
In the embodiment of the present disclosure, after the terminal switches the current network card to the target switching network card, the terminal further sets the current network card to the disabled mode. In practical application, the network card a in the terminal accesses the network area a, and after data transmission with the server a is realized, other network cards including the network card B are disabled. When the network card B in the terminal is accessed to the network area B and transmits data with the server B, other network cards except the network card A are kept in a use prohibition state, so that the network card A only needs to be forbidden on the terminal, and the network card A cannot be accessed to the network area B, so that data transmission between other programs and the network card A by using the network card A can be avoided, the management of safety products is enhanced, and the occurrence of secret leakage events is reduced.
The embodiment of the disclosure provides a network switching method, which is applied to a terminal configured with a plurality of network cards, the terminal is switched from a current network area A to a current network area B, a safety product under the network area B does not need to be reinstalled, and whether a network segment address corresponding to an IP address of the network card B exists in network segment addresses in a pre-configuration file or not can be directly inquired. If the network segment address exists, the server address corresponding to the network segment can be obtained according to the corresponding relation between the network segment address and the server address in the pre-configuration file, and the terminal is connected with the server B through the network card B, so that the switching of the network area where the terminal is located is realized. Therefore, in the embodiment of the disclosure, the terminal is switched from the current network area a to the network area B, and the security product in the network area B does not need to be reinstalled, which is beneficial to deployment and management of the terminal and is convenient for the user to use the security product.
