[0026] The present invention adopts a combination of a microcontroller unit MCU and an Ethernet switching module to expand the interface that only supports a specific network interface, connects to the specific network interface through the uplink interface of the Ethernet switching module, and then connects to other Ethernet devices through multiple Ethernet downlink interfaces.

The switching module can also be used to achieve the transmission and processing of Ethernet data, for example, including Ethernet PHY interfaces and MAC controllers to achieve the transmission and processing of Ethernet data.

[0029] Figure 1 FIG. 1 is a schematic diagram of a network communication device according to an embodiment of the present disclosure. Figure 1 As shown, the network communication device 100 includes an Ethernet switching module 102 and a microcontroller unit MCU 104. The Ethernet switching module 102 includes an Ethernet uplink port and multiple Ethernet downlink ports, wherein the Ethernet switching module is configured to route messages between the Ethernet uplink port and the multiple Ethernet downlink ports. The Ethernet switching module 102 is designed with an Ethernet uplink port and multiple Ethernet downlink ports. The chip is responsible for routing messages between these ports to ensure that the messages can be transmitted in the network according to a predetermined path.

[0030] The microcontroller unit MCU 104 includes a specific network interface (e.g., a GMAC interface) connected to an upstream port of the Ethernet switching module, wherein the microcontroller unit is configured to perform network device information linked list processing on messages from the specific network interface, thereby routing messages received via the specific network interface to an upper-layer network service and routing messages from the upper-layer network service to corresponding ports among a plurality of Ethernet downstream ports via the specific network interface.

[0031] MCU 104 is the core processing unit of the system, which is connected to the uplink port of the Ethernet switch module through a specific network interface (GMAC). MCU is responsible for performing network device information linked list processing, which includes receiving messages from the specific network interface and routing them to the upper network service. At the same time, it also processes messages sent from the upper network service and sends them to the corresponding downlink port of the Ethernet switch module through the specific network interface.

[0032] MCU 104 is the core processing unit of the network communication system, which usually includes a microprocessor (CPU), memory, input / output (I / O) ports, timers / counters, communication interfaces, and interrupt controllers. The microprocessor executes instructions in the instruction set architecture and processes data. The memory includes program memory (such as ROM or Flash) and data memory (such as RAM). The I / O port is used to communicate with external devices, and communication interfaces such as UART, SPI, I2C, USB, etc. are used for data exchange. The interrupt controller manages external interrupt requests. Based on the above technical features, multiple modules can be installed in MCU 104 to route messages from multiple downstream ports for transmission to upper-layer network services.

[0033] Figure 2 FIG. 2 shows a schematic diagram of a microcontroller unit according to an embodiment of the present disclosure. Figure 2 As shown, the micro control unit 200 includes a configuration binding module, a port attribute module, a port switching module, a data forwarding module and a network protocol stack. Figure 2 In the embodiment, the software modules of the micro control unit 200 from bottom to top are PORT port attribute module, PORT port switching module, configuration binding module, data forwarding module, network protocol stack and various network services.

[0034] The configuration binding module is configured to perform configuration on the network protocol stack, port attribute module and data forwarding module. The configuration binding module is a component of the MCU and is responsible for configuring the network protocol stack, port attribute module and data forwarding module. Through this module, the system can adapt to different network environments and communication requirements.

[0035] The port attribute module is configured to establish a network device information linked list binding between the ports corresponding to the plurality of Ethernet downstream ports and the network protocol stack according to the configuration of the configuration binding module and transmit the bound network device information linked list binding information to the port switching module. According to the setting of the configuration binding module, the port attribute module establishes a network device information linked list binding between the plurality of Ethernet downstream ports and the network protocol stack. This binding process ensures that the message can be correctly identified and routed.

[0036] The port switching module is configured to switch the ports corresponding to the multiple Ethernet downstream ports of the message according to the network device information linked list information bound by the port attribute module. The port switching module uses the network device information linked list information bound by the port attribute module to determine which Ethernet downstream port the message should be sent to.

[0037] The data forwarding module is configured to forward the message to the network protocol stack according to the port switched by the port switching module. The module forwards the message to the network protocol stack according to the decision of the port switching module for further processing and routing.

[0038] The network protocol stack is configured to route the message forwarded by the data forwarding module to the upper network service and route the message from the upper network service to the data forwarding module based on the network device information linked list configured by the port attribute module. The network protocol stack is the highest-level software component in the entire system. It routes the message to the upper network service based on the network device information linked list configured by the port attribute module, and routes the response message from the upper network service back to the data forwarding module.

[0039] The overall process is that in the overall initialization phase, the network management initialization module configures the network protocol stack and the PORT port attribute module by configuring the binding module. By binding the physical PORT port attribute and the IP address attribute and passing the bound network device information list information to the data forwarding module and the PORT port switching module.

[0040] When normal communication is fully established and communication begins, data is bidirectionally exchanged only by the network protocol stack, data forwarding module, and PORT port switching module, and other modules are no longer involved.

[0041] The network device information list includes IP address information, Mask mask, GW gateway and the port identifier to which the Ethernet downstream port belongs. The network device information list is associated and matched with the network protocol stack port, and it must also be matched with the attributes of the switch port. The attribute matching of the switch port can be done through special identifiers, such as CPU PORT, VLAN ID, custom identifiers, etc. Through the above IDs or representations, the corresponding relationship between the network device information list (NetDev structure) and the external expansion port of the switch chip is established. The network device information list processing can be one-to-many, many-to-many, and many-to-one. Furthermore, the same port uses different network addresses, different ports use different network addresses, and different ports use the same network address. Then it is extended to the establishment relationship between the upper-layer network service and the network address. This solution can use the network protocol stack to establish different network services with the same network address, or different network services with different network addresses, etc., so that the purpose of matching different network services to different ports can be achieved.

[0042] Figure 3 FIG. 2 is a schematic diagram showing a network device information linked list processing executed by a network communication system according to an embodiment of the present disclosure. Figure 3As shown, in one embodiment, the network communication system can be configured in multiple ways through the network device information linked list. For example, one-to-many configuration management is implemented, such as port 1 is associated with 3 network device information linked lists (NetDev structure); scenario two: one-to-one configuration management is implemented, such as ports 2 / 3 / 4 are each bound to their own independent network device information linked lists (NetDev structure); scenario three: many-to-one configuration management is implemented, such as ports 5 / 6 / 7 are associated with 3 network device information linked lists (NetDev structure) with the same network information; scenario four: a combination of the above three, such as the combination of port 1 and port 2.

[0043] Although the port mapping schemes are different, there is a common network information structure. Network device information linked list binding includes one or more of the following binding relationships: binding an Ethernet downstream port to a network device information linked list, wherein the network device information linked list corresponds to an IP address information; binding an Ethernet downstream port to multiple network device information linked lists, wherein the multiple network device information linked lists correspond to multiple different IP address information respectively; and binding multiple Ethernet downstream ports to multiple network device information linked lists, wherein the multiple network device information linked lists correspond to the same IP address information respectively.

[0044] In one embodiment, when the system receives a message from an upper-layer network service and the message is identified as a broadcast message, the system will execute a broadcast routing strategy. The broadcast routing strategy includes copying and routing the received broadcast message to all configured Ethernet downstream ports. This process ensures that the broadcast message can be received on all terminal devices within the network and is suitable for scenarios where messages need to be broadcast to all devices. In the present invention, broadcast refers to broadcasting based on an IP address information interval or unicasting based on specific IP address information. Broadcasting refers to sending data messages to all possible specific IP address segments in the network. Unicast refers to sending and receiving messages with ports with specific IP address information.

[0045] For non-broadcast message processing, the system will process it according to the IP address information in the network device information list contained in the message. The system matches the IP address in the message with the port identifier to which the Ethernet downstream port belongs.

[0046] If the IP address information and port identifier in the message match the IP address and port identifier of any Ethernet downstream port, the message will be routed to the corresponding port. If the IP address information and port identifier in the message do not match any Ethernet downstream port, the system will discard the message according to the routing rules to avoid invalid routing attempts.

[0047] The system will continuously check the destination IP address and port identifier of each received message. If the IP address and port identifier of the received message match the configuration of a downstream Ethernet port in the system, the system will perform routing operations and forward the message to that port.

[0048] This process ensures that only correct and well-targeted messages are routed to the corresponding network devices, improving network efficiency and security. If the system detects that the IP address and port identifier of the received message do not match any configured Ethernet downstream port, the message will be considered as having an unclear purpose. The system will execute a discard mechanism to avoid sending messages to the wrong port, reducing network congestion and potential security risks.

[0049] In one embodiment, when the system receives a broadcast message through a specific network interface, the system will execute a special routing rule. The rule requires the system to route the received broadcast message to all configured upper-layer network services. This process ensures that the broadcast message can be propagated in all upper-layer services, so that all relevant devices in the network can receive the broadcast message. For non-broadcast messages, the system will determine the corresponding upper-layer network service based on the IP address information and Port port identifier of the network device information linked list contained in the message. The system will check the IP address and Port port identifier in the message and match them with the IP address and Port port identifier of the upper-layer network service configured in the system.

[0050] If the IP address and port identifier in the message match the configuration of a certain upper-layer network service, the system will perform a routing operation and forward the message to the upper-layer network service. This process ensures that the message can be correctly routed to the target service, improving the accuracy and efficiency of network communication.

[0051] If the system detects that the IP address and port identifier of the received non-broadcast message do not match any configured upper-layer network services, it is considered that the message cannot find a suitable route. The system will execute the discard mechanism and give up further processing of the message to avoid invalid routing attempts and potential network congestion.

[0052] If the IP address and port identifier in the message completely match the configuration of a certain upper-layer network service, the system will confirm that the upper-layer network service is the destination service of the message. The system will then route the message to the determined upper-layer network service, completing the final step of data transmission.

[0053] Through the above embodiments, the network communication system can intelligently process received messages, whether broadcast messages or unicast messages, and ensure that the correct routing strategy is executed, while avoiding invalid routing attempts, thereby improving the operating efficiency and stability of the network.

[0054] The above Ethernet downstream port is an information socket connector for connecting to a data terminal device or for connecting to a digital communication device, such as an RJ45 interface.

[0055] Figure 4 FIG. 2 shows a schematic diagram of a network communication system performing uplink communication according to an embodiment of the present disclosure. Figure 4 As shown, in step 402, the Ethernet switching module receives messages from one or more of the multiple Ethernet downstream ports and routes the received messages to a specific network interface of the micro control unit via the Ethernet upstream port.

[0056] In step 404, the micro control unit verifies the network device information linked list of the received message, and routes the received message to the corresponding upper layer network service based on the verification result of the network device information linked list.

[0057] Figure 5 FIG. 2 shows a schematic diagram of a network communication system performing downlink communication according to an embodiment of the present disclosure. Figure 5 As shown, in step 502, the micro control unit receives a message from an upper layer network service and checks the network device information linked list of the received message to route the received message to the Ethernet uplink port of the Ethernet switching module via a specific network interface.

[0058] In step 504, the Ethernet switching module receives the message from the micro control unit and routes the received message to the corresponding Ethernet downstream port based on the verification result of the network device information linked list.
