Detailed Description
To make the objects, technical solutions and advantages of the present specification more apparent, the present specification is further described in detail below with reference to the accompanying drawings in combination with specific embodiments.
It should be noted that technical terms or scientific terms used in the embodiments of the present application should have a general meaning as understood by those having ordinary skill in the art to which the present application belongs, unless otherwise defined. The use of "first," "second," and similar terms in the embodiments of the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that a element, article, or method step that precedes the word, and includes the element, article, or method step that follows the word, and equivalents thereof, does not exclude other elements, articles, or method steps. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
As described in the background section, for an intelligent device provided with two or more sets of operating system hardware devices, such as a computer equipped with two or more hosts, currently, to implement interaction or network sharing between these hosts, switch hardware, such as switch hardware, needs to be added between the hosts, where two or more systems are respectively connected to different ports of the switch, and an external port is also connected to one port of the switch, so that network sharing can be implemented.
However, such an arrangement would increase the overall product cost after the addition of the hardware switch. Moreover, when one system of the multiple systems is accessed to the wireless network, because the hardware switch itself cannot perform wireless network connection, other systems cannot realize network sharing of the multiple systems through the hardware switch, and other systems can only perform wired or wireless connection through respective network cards and cannot realize network sharing.
In combination with the above actual situation, the embodiment of the present application provides a network sharing method, which is applied to an intelligent device with multiple systems. The intelligent device can be a computer provided with at least two system hosts, an intelligent large screen provided with at least two sets of system hardware, a portable computer or a mobile terminal and the like. In the smart device, a plurality of systems are directly connected in communication by means of data lines and the like, for example, connected by USB lines, network lines, COM lines or Type-C lines and the like. Each system comprises a network card, and the systems communicate through the network cards arranged in the systems. When one of the network cards is connected with an external network, the other network cards can also perform data interaction with the external network through communication between the other network cards and the network card. According to the embodiment of the application, hardware such as switches and the like arranged among systems in the prior art can be saved on the premise of not influencing the network interaction function of multiple systems, and the use of users on multiple systems is not influenced while the cost is saved. The following describes specific examples of the present application.
As shown in fig. 1, a schematic flow chart of a network sharing method provided in an embodiment of the present application is shown, where the method specifically includes:
In this step, by acquiring the output network data of the second network card, address conversion is performed on the output network data of the second network card at the first network card side in the subsequent steps, so that the second network card can perform network data interaction through the first network card.
In this step, the first network card is a network card set in a first system of the intelligent device, and the second network card is a network card set in a second system of the intelligent device. The first system and the second system can be any intelligent operating system, such as an android system, a windows system, a Linux system and the like. The first system and the second system may be the same or different in type, and the embodiments of the present application are not limited thereto. After the first system is connected with an external network, a first network card in the first system is started, and the first system performs data interaction with the external network through the first network card. The first network card type is also different according to the external network type. When the external network is a wired network, the first network card is a wired network card; when the external network is a wireless network, the first network card is a wireless network card. The second network card can be a wired network card or a wireless network card. In order to save cost and to establish a stable connection with the first network card, the second network card is generally a wired network card.
The output network data is network data transmitted by the second system to the external network. And a communication channel is established between the second network card and the first network card, when the output network data is transmitted, the processor of the second system generates output network data according to the operation of the user on the intelligent device, the output network data is transmitted to the second network card, and the second network card transmits the output network data to the first network card through the communication channel. And then, the output network data is output data of the second system in the network interaction process, and is generally request uplink data.
And 102, converting the source address of the output network data into a source address corresponding to the first network card to obtain the converted output network data.
In this step, the address conversion of the output network data is completed by converting the source address of the output network data, and the output network data transmitted by the second network card is converted into the output network data to be transmitted by the first network card.
In a data interaction scenario, the source address of the output network data is the IP address of the system that outputs the data packet of the output network data, and is generally recorded in the header portion of the data packet. In this step, the source address of the output network data is the IP address of the second system. The same source address corresponding to the first network card is the IP address of the first system corresponding to the first network card. That is, in this step, the header portion in the data packet of the output network data is modified, and the recorded output address is modified from the IP address of the second system to the IP address of the first system.
In a specific application scenario, dynamic source address target conversion (SNAT) may be performed on data output by the second network card on the first network card side. For example, in a network formed by a first system and a second system, the first system can communicate with an external network through a first network card, that is, the first network card is connected to a public network, a second network card of the second system is only connected to the first network card, that is, the second network card is connected to an intranet, and the second network card can communicate with the external network only through the first network card. When the second system needs to access the external network, the header part of the output data packet can only fill in the IP address of the internal network, and the output data packet can only flow in the internal network. And then, the second system transmits the data packet to the first network card through the intranet through the second network card, the header part of the data packet is replaced at the first network card, and the data packet is replaced by the IP address of the first system corresponding to the first network card. And finally, generating the converted output network data after the source address conversion is finished.
In this step, the converted output network data is seen by the external network as data output by the first network card, and at the external network end, the converted output network data is only considered to be in data interaction with the first network card, so that the network data interaction can be performed even if the second network card of the second system is not communicated with the external network. That is, at this time, the external network acquires the data packet that has been the output network data of the replaced header portion, and records the public network IP address of the first system, but not the internal network IP address of the second system.
In a specific application scenario, as shown in fig. 2, a schematic diagram of a specific application flow of the network sharing method provided by the present application is shown. In the dual-system device, the wired or wireless connection of the Android system serving as the first system is successful, and the corresponding wired network card A or wireless network card B is started, so that the Android system can surf the internet. Starting the network card C of the second system, updating the route of the network card C to the wired network card A or the wireless network card B, so as to establish a communication channel between the two network cards, and further establish communication connection between the first system and the second system, and the network data output outwards by the second system carries out source address conversion at the wired network card A or the wireless network card B, so that the external network considers that the network data is transmitted by the first system but not transmitted by the second system when receiving the network data.
As can be seen from the above, in the embodiment of the present application, by establishing a communication connection between two systems, and when acquiring the output network data of the second network card, converting the source address of the output network data, and converting the address of the second system recorded in the output network data into the address of the first system, the output network data can be transmitted through the first system when the second system needs to perform network data interaction, so that on the premise of not affecting the network interaction function of multiple systems, hardware such as switches in the prior art can be saved, and the use of the dual systems by a user is not affected while the cost is saved.
It should be noted that the method of the embodiment of the present application may be executed by a single device, such as a computer or a server. The method of the embodiment of the application can also be applied to a distributed scene and is completed by the mutual cooperation of a plurality of devices. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of the embodiment, and the multiple devices interact with each other to complete the method.
It should be noted that the above-mentioned description describes specific embodiments of the present application. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments described above and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In other embodiments, after the converted output network data is sent to the first network card, the input network data transmitted from the external network to the first network card is acquired; the input network data is network data generated by the external network in response to the converted output network data; converting the destination address of the input network data into a source address corresponding to the second network card to obtain converted input network data; and transmitting the converted input network data to a second network card.
In this embodiment, the input network data corresponds to the output network data, and is feedback data generated for the output network data by the external network. In this step, after the first network card outputs an output network data, the external network generally generates an input network data according to the output network data and transmits the input network data back, and the input network data necessarily carries the identifier of the output network data corresponding to the input network data. Therefore, the identifier can be used to determine the feedback information of which output network data the input network data is, and then the output network data can be used to determine which network card is the final data transmitted. Then, destination address translation (DNAT) is performed on the input network data belonging to the second network card. In a specific application scenario, the first system and the second system form an intranet, wherein a second network card of the second system is configured with an intranet IP address, and a first network card of the first system is configured with a public network IP address. When a data packet of the output network data of the second network card is acquired, the first system performs source address conversion on the data packet and records the identifier of the data packet. And then, after receiving the data packet, the external network generates a data packet of input network data according to the data packet and transmits the data packet to the first network card, and at the moment, the target address of the data packet writes the public network IP address of the first network card. At this time, the data packet inevitably carries information related to the output network data corresponding to the data packet, and the actual destination address of the input network data, which is the source address corresponding to the second network card in this embodiment, can be finally confirmed by comparing the information with the previous identifier. Then, the destination address of the packet head part of the data packet of the input network data is rewritten into the intranet IP address of the second network card, and then the data packet is sent to the second network card of the intranet, so that the data packet passes through the first network card and is changed from the public network IP into access to the intranet address. And finally, after the data input by the external network passes through the DNAT, the data of the external network is forwarded to the side of the second network card from the side of the first network card through a data forwarding program, so that network sharing is finally completed. In a specific application scenario, the data of the second network card may be forwarded through the kernel. Kernel refers to the core of most operating systems. It consists of those parts of the operating system that are used to manage memory, files, peripherals, and system resources. The operating system kernel typically runs processes and provides inter-process communication.
In some other embodiments, the number of the second systems is multiple, and each second system comprises a corresponding second network card; the output network data carries the identification information of the second network card; converting the destination address of the input network data into a source address corresponding to the second network card to obtain the converted input network data, including: determining a source address corresponding to the target second network card according to the identification information; the target second network card is a second network card for transmitting and outputting network data; converting the destination address of the input network data into a source address corresponding to the target second network card to obtain converted input network data; transmitting the converted input network data to a second network card, comprising: and transmitting the converted input network data to the target second network card. Therefore, the system input data specifically corresponding to the input network data is accurately identified, and the data transmission is accurately carried out.
In this embodiment, the identification information is information that can point to the corresponding second network card, and the first system can accurately find the second network card through this information, and can distinguish which information belongs to the second network card or the second system. In a specific application scenario, a label of each network card can be set, when the network card generates output network data, the output network data carries the label, and when source address conversion is performed on the first network card side, label recording is performed; when the external network acquires the output network data, although the source address of the output network data changes, the label cannot be changed, and when the external network generates the input network data, the label is transferred to the input network data; when the first network card receives the input network data, it can identify the input network data as the feedback of which output network data, specifically as the data of which network card, according to the tag. In a specific application scenario, the first system may be an android system, and the plurality of second systems may be windows systems, mac systems, or linux systems. Then, after the identification information is sent to the first network card side, the content of the identification information is written into the data interaction service of the first system, different operating systems generally correspond to different data interaction service programs, and the data interaction service of the Android system, for example, is netD. In a specific application scenario, after the routing information of the second network card is updated to the first network card, the netD of the Android system of the first system is stopped, the second network card is added into the netD (i.e., the identification information of the second network card is added into the netD of the first system), and the netD is restarted. Therefore, the acquired input network data of the external network can be accurately identified to which second system the input network data is finally transmitted at the first network card side. Then, since the input network data is generally feedback for the output network data, the input network data necessarily carries the relevant information of the output network data corresponding to the input network data, and the first system can determine the identification information corresponding to the input network data by reading the relevant information, so that the corresponding second network card, namely the target second network card, can be accurately determined according to the identification information. And finally, after the target second network card is determined, the input network data subjected to the destination address conversion is transmitted to the target second network card.
In some other embodiments, determining the source address corresponding to the target second network card according to the identification information includes: searching a source address corresponding to the identification information in a second network card address corresponding table according to the identification information to determine a source address corresponding to the target second network card; the second network card address corresponding table stores the corresponding relationship between the identification information and the source address corresponding to the second network card. Therefore, the source address corresponding to the target second network card is accurately determined.
In this embodiment, after counting the identification information carried by the output network data, the first system establishes a second network card address correspondence table, and establishes a correspondence between each identification information and each second network card, so that after the input network data comes, the corresponding second network card and the source address thereof can be directly found through the second network card address correspondence table.
In some other embodiments, the output network data carries an output time of the output network data; converting the source address of the output network data into a source address corresponding to the first network card to obtain the converted output network data, including: determining a source address corresponding to the first network card according to the output time; the source addresses corresponding to the first network cards are the same at the same time, and the source addresses corresponding to the first network cards are different at different times; and converting the source address of the output network data into the source address corresponding to the first network card to obtain the converted output network data. Therefore, the source address can be dynamically converted, so that the use cost and the maintenance cost are reduced.
In a specific application scenario, the SNAT in a general fixed source address translation, no matter a few addresses, must explicitly specify the IP address of the SNAT to be used. If the current system uses ADSL dynamic dialing mode, the outlet IP address changes with a large change amplitude every dialing, however, the converted source address IP must be consistent with the outlet IP or fluctuate within a small range to establish a good connection, for example, the outlet IP is 192.168.5.3, and the source address converted IP address is generally an address in the range of 192.168.5.3 to 192.168.5.5, which is a problem if it is configured in a fixed source address conversion mode. Because the server address changes after each dialing, the IP address converted by the fixed source address cannot change along with the automatic change, the IP address must be manually modified once after each address change, and the fixed IP address in the rule is changed into a new IP address, which is very inconvenient and can increase the use cost and the maintenance cost. Therefore, in this embodiment, the output time of the output network data is determined, so as to determine the source address corresponding to the first network card at the output time, and address conversion is performed through the source address. In a specific application scenario, dynamic source address conversion as in this embodiment may be performed through masquerade.
In some other embodiments, converting the source address of the output network data into the source address corresponding to the first network card to obtain the converted output network data includes: acquiring a source address list corresponding to a first network card; a plurality of source addresses corresponding to the first network card are stored in the source address list; and converting the source address of the output network data into any one source address in the source address list to obtain the converted output network data. Therefore, the conversion speed of source address target conversion is increased, and the network data interaction can be carried out on the output network data more quickly.
Although the fixed source address translation approach has certain problems, as described in the previous embodiment, it is generally only fluctuating within a certain range, even by dynamic dialing, as it is used on a daily basis. Therefore, in order to accelerate the interaction speed, a source address list can be set to record a common IP address, so that the source address can be directly used during conversion, and the reaction speed is improved. That is, in this embodiment, the source address list is a list recording one or more commonly used source addresses corresponding to the first network card, and after the output network data is obtained, one source address is randomly selected according to the source addresses recorded in the source address list to perform fast source address target conversion, so that the conversion speed is increased.
In some other embodiments, before acquiring the output network data transmitted from the second network card to the first network card, the method further includes: activating the first network card to enable the first system to perform network interaction through the first network card; and activating the second network card, acquiring the routing information of the second network card, and writing the routing information into the first network card so as to establish a data communication channel between the first network card and the second network card. Therefore, the communication relation between the first network card and the second network card is effectively established.
