Background
In existing designs, a router includes multiple Local Area Network (LAN) interfaces.

However, in the current design scheme of the router, since data of a plurality of lan interfaces are all received through the same ethernet interface, when each data is sent to a bridge of a corresponding service through the ethernet interface, the router cannot determine the service that each data needs to perform, and thus cannot send each data to the bridge of the corresponding service, and when the router receives response information for a certain data, the router cannot send the response information to the corresponding lan interface, so that a terminal that sends the data to the lan interface cannot implement a corresponding service function.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating the overall scheme of the present application. In all embodiments of the present application, the execution subject of the data distinguishing method is a router. As shown in fig. 1, the terminal device 10 is mounted under the router 20, and establishes a communication connection with the server 30 through the router 20. The terminal device 10 may include, but is not limited to, a smart phone, a tablet computer, a desktop computer, or the like. The server 20 may be a server or a processor in the server, and the server may be a tablet computer or a desktop computer.
In implementation, the terminal device 10 may also be an intelligent household appliance such as a television, a set-top box, and the like. However, the data distinguishing method implemented in the router 20 is not changed regardless of the type of the terminal device 10 mounted under the router 20.
Taking the terminal device 10 as a mobile phone as an example, the mobile phone sends first data to the router 20, the router 20 configures a first Virtual Local Area Network Tag (VLAN Tag) for the first data received through the first preset Local Area Network interface, so as to obtain the first data carrying the first Virtual Local Area Network Tag, because the first Virtual Local Area Network Tag is used to describe service content corresponding to the first data, and a data sending path including the target Virtual interface and the target bridge can be determined according to the first Virtual Local Area Network Tag, the router 20 sends the first data to the service end 30 through the data sending path.
As shown in fig. 1, the router 20 includes a forwarding unit 21, a processing unit 22, local Area Network (LAN) interfaces 23 (4 are shown), ethernet interfaces, and Wide Area Network (WAN) interfaces 25. The forwarding Unit 21 may be a Switch chip, and the Processing Unit 22 may be a Central Processing Unit (CPU).
In the embodiment of the present application, the terminal device 10 is communicatively connected to the router 20 through the local area network interface B3, and the server 30 is communicatively connected to the router 20 through the wide area network interface 25.
It should be noted that the terminal device 10 may be communicatively connected to the router 20 through any one of the lan interfaces B3.

In practical applications, the lan interface B3 is used for connecting the router 20 to a lan, the ethernet interface 24 is an interface for network data connection, that is, the ethernet interface 24 can transmit data between the forwarding unit 21 and the processing unit 22, and the wan interface 25 is used for connecting the router 20 to a wan.
Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of a data distinguishing method according to an embodiment of the present disclosure. In the embodiment of the present application, the main execution body of the data distinguishing method is a router. As shown in fig. 2, a data distinguishing method provided in the embodiment of the present application may include steps S201 to S203, which are detailed as follows:
in S201, configuring a first virtual local area network tag for first data received through a first preset local area network interface to obtain first data carrying the first virtual local area network tag; the first virtual local area network tag is used for describing service content corresponding to the first data.
In this embodiment of the application, after the router receives first data sent by the terminal device through the first preset local area network interface, the forwarding unit of the router may configure a first virtual local area network tag for the first data, so as to obtain the first data carrying the first virtual local area network tag. The first preset lan interface may be determined according to actual needs, and is not limited herein, and for example, the first preset lan interface may be any one of 4 lan interfaces of the router. The first virtual local area network label is used for describing the service content corresponding to the first data.
It should be noted that, in the embodiment of the present application, the router presets and stores the correspondence between different local area network interfaces and different services. For example, assuming that a router is configured with a lan interface a, a lan interface B, a lan interface C, and a lan interface D, and services that can be implemented by the router include service 1, service 2, service 3, and service 4, the router may set the service corresponding to the lan interface a as service 1, the service corresponding to the lan interface B as service 2, the service corresponding to the lan interface C as service 3, and the service corresponding to the lan interface D as service 4. Therefore, after the router receives the first data sent by the terminal device through the first preset local area network interface, the forwarding unit of the router may configure a first virtual local area network tag for the first data received through the first preset local area network interface based on the correspondence between the local area network interface and the service, so as to obtain the first data carrying the first virtual local area network tag.
In this embodiment, after obtaining the first data carrying the first vlan tag, the forwarding unit of the router may send the first data carrying the first vlan tag to the processing unit of the router through an ethernet interface of the router.
In S202, a data transmission path including the target virtual interface and the target bridge is determined according to the first vlan tag.
In this embodiment, after receiving the first data carrying the first vlan tag, the processing unit of the router may determine, according to the first vlan tag, a data transmission path including the target virtual interface and the target bridge. Here, the data transmission path describes a data transmission path at least including a virtual interface and a bridge in the communication process between the router and the server, where the virtual interface refers to an interface virtualized in advance by the router; the bridges are used for carrying services, and different bridges correspond to different services. The target virtual interface refers to a virtual interface for receiving the first data, and the target bridge refers to a bridge for transmitting the first data.
It should be noted that, in the embodiment of the present application, a corresponding relationship between a virtual interface and a bridge is preset in a router, for example, the virtual interface and the bridge are bound one by one, and services carried by each bridge are different. For example, it is assumed that the bridge includes a bridge a (for carrying service 1), a bridge b (for carrying service 2), a bridge c (for carrying service 3), and a bridge d (for carrying service 4), and the virtual interface includes a virtual interface 1, a virtual interface 2, a virtual interface 3, and a virtual interface 4, and the router may bind the virtual interface 1 with the bridge a, bind the virtual interface 2 with the bridge b, bind the virtual interface 3 with the bridge c, and bind the virtual interface 4 with the bridge d.
Based on this, the processing unit of the router may determine, according to the service content described by the first vlan tag, the virtual interface and the bridge corresponding to the service content, so as to determine the virtual interface and the bridge corresponding to the service content as the data transmission path corresponding to the first data.
For example, in combination with S201, assuming that the service content corresponding to the first data is the content of the service 1, the bridge for carrying the service 1 is a bridge a, and the bridge a is bound to the virtual interface 1, the processing unit of the router may determine the virtual interface 1 as a target virtual interface, and determine the bridge a as a target bridge, so as to determine that the data transmission path corresponding to the first data is a data transmission path including the virtual interface 1 and the bridge a.
In an embodiment of the application, since the first vlan tag may affect subsequent processing of the first data, the processing unit of the router may remove the tag of the first data carrying the first vlan tag according to a first preset policy after determining a data transmission path of the first data according to the first vlan tag, so as to obtain the first data, and the data transmitted by the processing unit of the router in a subsequent data transmission process is only the first data. Wherein the first preset policy may be to execute a vlan ctl command.
In S203, the first data is sent to the server through the data sending path.
In this embodiment of the application, after determining the data transmission path of the first data, the processing unit of the router may transmit the first data to the server through the data transmission path.
It should be noted that the first data sent in this embodiment is the first data that does not carry the first vlan tag.
As an embodiment of the present application, the data transmission path is comprised of a target virtual interface, a target bridge, and a wide area network interface. Therefore, the processing unit of the router may send the first data to the server via the target virtual interface, the target bridge, and the wide area network interface in that order.
Specifically, the first data may be sent to the server through the following steps, which are detailed as follows:
and sending the first data to the target bridge through the target virtual interface.
Sending the first data to a wide area network interface through the target bridge.
And sending the first data to the server through the wide area network interface.
In this embodiment, after determining the data transmission path corresponding to the first data and including the target virtual interface and the target bridge, the processing unit of the router may first send the first data to the target virtual interface, and then send the first data to the target bridge through the target virtual interface.
After the processing unit of the router sends the first data to the target bridge, in order to realize the service function of the first data, the processing unit of the router can send the first data to the wide area network interface of the router through the target bridge, and then send the first data to the server through the wide area network interface.
As can be seen from the above, in the method provided in this embodiment, a first virtual local area network tag is configured for first data received through a first preset local area network interface, so as to obtain the first data carrying the first virtual local area network tag; the first virtual local area network label is used for describing the service content corresponding to the first data; determining a data transmission path comprising a target virtual interface and a target network bridge according to the first virtual local area network tag; and sending the first data to the server through the data sending path. According to the data distinguishing method, the first virtual local area network tag is configured on the first data received by the first preset local area network interface, and the first virtual local area network tag describes the service content corresponding to the first data, so that the data distinguishing device can determine the service corresponding to the first data according to the first virtual local area network tag. Therefore, the data distinguishing method provided by the application can distinguish different data according to the virtual local area network label, and further distinguish the service functions which need to be realized by different data.
Referring to fig. 3, fig. 3 is a flowchart illustrating an implementation of a data distinguishing method according to another embodiment of the present application. With respect to the embodiment corresponding to fig. 2, the data distinguishing method provided in this embodiment further includes steps S301 to S303, which are detailed as follows:
in S301, when second data sent by the server is received, configuring a second virtual local area network tag for the second data, to obtain second data carrying the second virtual local area network tag; the second virtual local area network tag is used for describing service content corresponding to the second data.
In this embodiment, since the second data is issued by the server, after the processing unit of the router receives the second data sent by the server, the processing unit of the router may determine a service corresponding to the second data, and thus the processing unit of the router may configure a second vlan tag for the second data to obtain the second data carrying the second vlan tag. And the second virtual local area network tag is used for describing service content corresponding to the second data.
Since the second data is sent by the server, the processing unit of the router can determine the service corresponding to the second data
In practical application, the server may actively send data to the router, or may send, after receiving the data sent by the router, return data corresponding to the data sent by the router to the router with respect to the data sent by the router. Based on this, in an embodiment of the present application, the second data sent by the server and received by the router may be data sent by the server to the second preset lan interface, that is, data actively sent by the server to the preset lan interface, or data returned by the server according to the first data. The second predetermined lan interface may be determined according to actual needs, and is not limited herein. It should be noted that the second predetermined lan interface is different from the first predetermined lan interface.
For example, assuming that the first predetermined lan interface is the lan interface a in the router, the second predetermined lan interface may be any one of the lan interface B, the lan interface C, and the lan interface D in the router.
It should be noted that, in this embodiment, the router binds the virtual interfaces and the bridges one by one in advance, that is, each virtual interface is bound to one bridge, and services carried by each bridge are different. For example, it is assumed that the bridge includes a bridge a (for carrying service 1), a bridge b (for carrying service 2), a bridge c (for carrying service 3), and a bridge d (for carrying service 4), and the virtual interface includes a virtual interface 1, a virtual interface 2, a virtual interface 3, and a virtual interface 4, and the router may bind the virtual interface 1 with the bridge a, bind the virtual interface 2 with the bridge b, bind the virtual interface 3 with the bridge c, and bind the virtual interface 4 with the bridge d.
Based on this, the processing unit of the router may determine, according to the service content described by the second vlan tag, the virtual interface and the bridge corresponding to the service content, so as to determine the virtual interface and the bridge corresponding to the service content as the data transmission path corresponding to the second data.
For example, assuming that the service content corresponding to the second data is the content of the service 2, the bridge for carrying the service 2 is a bridge b, and the bridge b is bound to the virtual interface 2, the processing unit of the router may determine the virtual interface 2 as the second virtual interface corresponding to the second data, and determine the bridge b as the second bridge corresponding to the second data, thereby determining that the data transmission path corresponding to the second data is a data transmission path including the virtual interface 2 and the bridge b.
Based on this, after obtaining the second data carrying the second vlan tag, the processing unit of the router may send the second data carrying the second vlan tag to the second virtual interface through the second bridge according to a data sending path corresponding to the second data, and then send the second data carrying the second vlan tag to the ethernet interface through the second virtual interface.
After sending the second data carrying the second vlan tag to the ethernet interface, the processing unit of the router sends the second data carrying the second vlan tag to the forwarding unit of the router through the ethernet interface.
In S302, a target lan interface corresponding to the second data is determined according to the second virtual lan tag.
In this embodiment, after receiving the second data carrying the second virtual local area network tag, the forwarding unit of the router may determine, according to the second virtual local area network tag, a target local area network interface corresponding to the second data.
It should be noted that, in this embodiment, the router presets and stores the correspondence between different local area network interfaces and different services. For example, assuming that a router is configured with a lan interface a, a lan interface B, a lan interface C, and a lan interface D, and services that can be implemented by the router include service 1, service 2, service 3, and service 4, the router may set the service corresponding to the lan interface a as service 1, the service corresponding to the lan interface B as service 2, the service corresponding to the lan interface C as service 3, and the service corresponding to the lan interface D as service 4. Therefore, after the forwarding unit of the router receives the second data carrying the second vlan tag, the forwarding unit may determine, according to the service content of the second data described by the second vlan tag, which service content the service content of the second data is, so as to determine, according to the service, the target vlan interface corresponding to the second data.
In an embodiment of the application, since the second vlan tag may affect subsequent processing of the second data, the forwarding unit of the router may perform tag removal on the second data carrying the second vlan tag according to a second preset policy after determining a target vlan interface corresponding to the second data according to the second vlan tag, so as to obtain the second data, so that the data sent by the forwarding unit of the router in a subsequent data sending process is only the second data. Wherein, the second preset strategy can be to execute a vlan command.
In S303, the second data is sent to the target lan interface.
In this embodiment, after determining the target lan interface, the forwarding unit of the router may send the second data to the target lan interface.
It should be noted that the second data sent in this embodiment is the second data that does not carry the second vlan tag.
As can be seen from the above, in the data distinguishing method provided in this embodiment, when second data sent by a server is received, a second virtual local area network tag is configured for the second data, so as to obtain the second data carrying the second virtual local area network tag; the second virtual local area network tag is used for describing service content corresponding to the second data; determining a target local area network interface corresponding to the second data according to the second virtual local area network label; and the second data is sent to the target local area network interface, so that the second data can be accurately sent to the target local area network interface corresponding to the service, the accuracy of data transmission is improved, and the terminal equipment in communication connection with the router through the target local area network interface can realize the required service function.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
