Referring to fig. 2, a flowchart of a communication method according to an embodiment of the present application is shown. The above communication method may be applied to the electronic device 10 shown in fig. 1. As shown in fig. 2, the communication method specifically includes the following steps, and the order of the steps in the flowchart may be changed and some steps may be omitted according to different requirements. As shown in fig. 2, the communication method in the embodiment of the present application includes steps 201 to 203.
The communication method provided by the present application may be applied to the first module in the electronic device 10, and the first module may be any module in the electronic device 10.
In step 201, the first port generally refers to any physical port of the first module. In the electronic device, each module is provided with at least one physical port, and the physical port can be in wired connection with other adjacent modules, so that the target data frame is the data frame received by the first module through the physical port. The first destination address is a destination address of the target data frame, and the first destination address is used for identifying a destination module for receiving the target data frame, i.e., indicating a receiver of the target data frame.
Fig. 3 is a schematic diagram illustrating connection of modules in an electronic device according to an example of the present application. In fig. 3, the electronic device includes three modules, which are module 1, module 2 and module 3, wherein module 1 is connected to module 2 and module 3, respectively. Wherein, the module 1 is connected with the port 2 of the module 2 through the port 1. When the module 2 sends the target data frame to the port 1 of the module 1 through the port 2, the module 1 may be understood as the first module, and the port 1 may be understood as the first port. The target data frame includes a first target address, and the first target address may be an address of the module 1 or an address of the module 3.
In an embodiment of the present application, the module for sending the target data frame encapsulates the target data frame according to a preset data packet format.
Fig. 4 is a schematic structural diagram of a preset data frame format according to an embodiment of the present application. The preset data frame may include a start header field, a frame type field, a source address field, a destination address field, a data length field, a data content field, and a check field. Wherein the start header field is used to indicate the start position of the frame. The frame type field is used to indicate the type of the frame. In this embodiment, the frame type corresponding to the frame type field includes a data frame, a probe frame, a response probe frame, a connection detection frame, and a response connection detection frame. The source address field indicates address information of a sender of the frame, and the destination address field indicates address information of a receiver of the frame. The data length field indicates the frame length. The data content field contains the data of the frame. The check field indicates the check bits of the frame. In an embodiment of the present application, the frame type of the target data frame is a data frame, and a target address field in the target data frame includes a first target address.
The first module receives a target data frame through a first port and acquires a first target address of the target data frame from a target address field of the target data frame.
In step 202, since the first target address is used to identify a destination module that receives the target data frame, that is, to indicate a receiver of the target data frame, when any module in the electronic device receives the target data frame through the port, it may be determined whether the module acquires data in the target data frame by comparing whether the first target address is the same as its own address.
In an embodiment of the application, if the first destination address is the same as the address of the first module, indicating that the receiver of the target data frame is the first module, the first module may obtain the data in the target data frame from the data content field of the target data frame.
In an embodiment of the application, if the first destination address is different from the address of the first module, which indicates that the receiver of the destination data frame is not the first module, the first module may determine, according to the routing table, a second port corresponding to the first destination address, and send the destination data frame through the second port.
In an embodiment of the application, the determining, by the first module, the second port corresponding to the first destination address according to the routing table includes: acquiring a routing table corresponding to each port (for example, port 111 in fig. 1) of a first module; and determining the port corresponding to the routing table containing the first target address as a second port.
In an embodiment of the present application, each port 111 of the first module may correspond to a different routing table. The routing table of the port 111 records the addresses of the modules 11 to which the port 111 can be connected. In the embodiment of the application, the port corresponding to the routing table containing the first destination address is determined as the second port, so that the first module can send the target data frame to the module corresponding to the first destination address through the second port. For example, referring to the example shown in fig. 3, assuming that the first destination address is the same as the address of the module 3, and the port 3 of the module 1 is connected to the port 4 of the module 3, at this time, since the module 1 detects that the address of the module 3 is included in the routing table corresponding to the port 3, the module 1 may determine the port 3 as the second port, and forward the destination data frame to the module 3 through the port 3.
In the method provided by the embodiment of the present application, when a first module receives a data frame, it may be determined whether the first module is a receiving object of the first data frame according to a first target address in the data frame. If the first module is not the receiving object of the data frame, the first module can determine a second port for forwarding the first data frame according to the first target address and the routing table, and transmit the first data frame to a next module in the data transmission link through the second port, and through a data transfer mode, the technical problems that each module of the original electronic equipment needs to be provided with a physical port and a connecting line separately for realizing data transmission, so that the communication circuit is complex and the number of flying lines is increased can be effectively solved.
In an embodiment of the present application, when it is detected that the electronic device 10 is powered on or a module in the electronic device establishes a communication connection with another module, each module 11 in the electronic device 10 indicates, according to a pre-configuration document, the corresponding module to send a probe frame to the other module, so as to establish a communication connection between the modules 11. The pre-configuration document defines the communication requirements between each module 11 and the other modules. When receiving the probe frame sent by the other modules, the first module may reply the response frame to the module corresponding to the source address of the probe frame according to the probe frame, or forward the probe frame to the next module, so as to complete the process of establishing the communication connection between the modules 11 of the electronic device 10.
And when receiving the detection frame of the other module, the first module may record the source address of the detection frame on the routing table corresponding to the port receiving the detection frame, thereby establishing the routing table of each port of the first module. That is to say, the first destination address recorded in the routing table of the second port may be recorded in the routing table of the second port by the first module after receiving, through the second port, the probe frame sent by the first destination address.
Referring to fig. 5, a schematic flow chart of the first module receiving and processing a probe frame in this embodiment is shown, which specifically includes the following steps.
In an embodiment of the present application, the first module receives, through the second port, the first probe frame sent by the other module. And packaging the first detection frame according to the preset data packet format. In the embodiment of the present application, the specific content of the first probe frame encapsulated according to the preset data packet format may refer to the content of the target data frame encapsulated, and is not described herein again. For example, with reference to the example shown in fig. 3, it is assumed that module 1 receives a first probe frame sent by module 3 through port 4 through port 3, and the source address of the first probe frame is the first destination address, i.e. the address of module 3. At this time, the port 3 may be understood as the above-described second port.
In an embodiment of the present application, the first module may record the first destination address, that is, the source address of the first probe frame, in the routing table corresponding to the second port. It can be understood that, since the first module receives the probe frame with the source address being the first destination address through the second port, which indicates that the first module can communicate with the module corresponding to the first destination address through the second port, the first module can record the first destination address in the routing table corresponding to the second port, so as to subsequently communicate with the module corresponding to the first destination address through the second port.
It should be noted that in all embodiments of the present application, a physical port of each module may be provided with a corresponding routing table, and the contents in the routing table are used to describe addresses of other physical ports communicating with the physical port.
Step 503, if the destination address of the first probe frame is the same as the address of the first module, sending a first response frame through the second port, where the source address of the first response frame is the address of the first module, and the destination address of the first response frame is the first destination address.
In an embodiment of the present application, if the target address of the first probe frame is the same as the address of the first module, that is, it is determined that the receiver of the first probe frame is the first module, the first module returns a first response frame to the sender of the first probe frame after receiving the first probe frame, so as to indicate that the first module has received the first probe frame. The source address of the first response frame is the address of the first module, which means that the sender of the first response frame is the first module. The destination address of the first response frame is a first destination address, which indicates that the receiver of the first response frame is the sender of the first probe frame. In the embodiment of the present application, the specific content of the first response frame encapsulated according to the preset data packet format may refer to the content of the target data frame encapsulated, and is not described herein again.
In step 504, if the target address of the first probe frame is different from the address of the first module, the first probe frame is sent through a port other than the second port.
In an embodiment of the application, if the destination address of the first probe frame is different from the address of the first module, that is, it is determined that the receiver of the first probe frame is not the first module, the first module sends the first probe frame through a port other than the second port after receiving the first probe frame. Specifically, the first module uses a port corresponding to a routing table that includes a destination address of the first probe frame, except the second port, as a forwarding port, and sends the first probe frame through the forwarding port. In this manner, the establishment of communication paths between the modules 11 of the electronic device 10 is facilitated.
In this embodiment, step 503 and step 504 are parallel steps, that is, step 503 and step 504 are not executed sequentially. After step 503 is performed, step 504 is not performed any more, and accordingly, after step 504 is performed, step 503 is not performed any more until the first module receives another probe frame through the second port again.
In addition, when the first module receives the response frame of the other module, the first module may record the source address of the response frame on the routing table corresponding to the port that receives the response frame, thereby establishing the routing table of each port of the first module. That is, the first destination address recorded in the routing table of the second port may be recorded in the routing table of the second port by the first module after receiving the response frame sent by the first destination address through the second port.
Referring to fig. 6, a schematic flow chart of the first module receiving and processing the second response frame in the embodiment of the present application is shown, which specifically includes the following steps.
In step 701, the first module receives a second response frame through the second port, where a source address in the second response frame is the first destination address.
In an embodiment of the application, the first module receives a second response frame sent by the module from the first destination address through the second port. In the embodiment of the present application, the specific content of the second response frame encapsulated according to the preset data packet format may refer to the content of the target data frame encapsulated as described above.
In an embodiment of the application, regardless of whether the first destination address is an address of the first module, the first module records the first destination address in a routing table corresponding to the second port of the first module, so as to indicate that the first module can communicate with the module corresponding to the first destination address through the second port.
In an embodiment of the application, if the destination address of the second response frame is different from the address of the first module, that is, the receiver of the second response frame is not the first module, the first module determines, according to the routing table corresponding to each port of the first module, a third port corresponding to the routing table including the destination address of the second response frame as a port for forwarding the second response frame, and sends the second response frame through the third port.
In an embodiment of the present application, if the destination address of the second response frame is the same as the address of the first module, that is, the receiver of the second response frame is the first module, it indicates that the first module establishes a communication connection with the module corresponding to the first destination address. In order to maintain the connection state between the first module and the module corresponding to the first target address, the first module periodically sends a connection detection frame to the module corresponding to the first target address through the second port to monitor whether the first module maintains the connection state between the modules corresponding to the first target address. In the embodiment of the present application, the specific content of the connection detection frame encapsulated according to the preset data packet format may refer to the content of the target data frame encapsulated as described above.
In an embodiment of the application, after the first module sends the connection detection frame, if the connection response frame is not received within the preset time duration, it indicates whether the first module keeps the modules corresponding to the first target address in a disconnected state, and the first module modifies the routing table corresponding to the second port, for example, deletes the first target address or the address of the module connected to the second port in the routing table corresponding to the second port, and resends the probe frame pointing to the first target address. Therefore, the maintenance of the routing table of the port of the first module is realized, and the continuous communication connection between the first module and the module corresponding to the first target address is ensured.
In an embodiment of the present application, the first module may further send a probe frame to other modules of the electronic device 10 to complete a process of establishing a communication connection between the modules 11 of the electronic device 10. Referring to fig. 7, a schematic flow chart of sending a probe frame by a first module in an embodiment of the present application is shown, which specifically includes the following steps.
In an embodiment of the present application, the predetermined operation event includes at least one of an operation of starting the electronic device 10 or an operation of triggering modules of the electronic device 10 to establish a communication connection. For example, the user may press a power-on button of the electronic device 10 to input an operation to start the power-on of the electronic device 10. For another example, the user may trigger the operation of the modules of the electronic device 10 to establish a communication connection by adding a new module or resetting a communication path between the modules in the electronic device 10. When a preset operation event for establishing communication connection is detected, the first module determines the address of a module needing to communicate with the first module, namely a second target address, from the pre-configuration document.
In an embodiment of the present application, the first module uses an address of the first module as a source address of the second probe frame, and uses a second destination address of a module that needs to establish communication with the first module as a destination address of the second probe frame. In an embodiment of the present application, specific contents of the second probe frame encapsulated according to the preset data packet format may refer to the contents of the target data frame encapsulated as described above.
In an embodiment of the present application, the first module sends the second probe frame through each port of the first module, so as to establish communication between the first module and the module corresponding to the second target address.
Fig. 8 is a schematic structural diagram of a communication device 100 according to an embodiment of the present disclosure. The communication device 100 may be used to implement the communication method described above.
