Description

Technical Field

[0001] This invention relates to the field of mesh network technology, and in particular to a method, apparatus and storage medium for identifying routing messages in a mesh network. Background Technology

[0002] In the home networking field, WiFi Mesh networks have become a core networking solution for smart home scenarios due to their low-cost deployment, high flexibility, and strong signal coverage. From security devices such as smart door locks and cameras, to home appliances such as smart speakers and robot vacuum cleaners, and to multiple mobile terminals such as smartphones and tablets, all kinds of devices in the home rely on WiFi Mesh networks to achieve interconnection. Its mesh topology effectively eliminates signal blind spots, ensuring whole-house network coverage, allowing users to enjoy a stable, high-speed network connection whether they are in the living room, bedroom, or a corner. However, the Layer 2 network architecture used in home WiFi Mesh networks presents a challenging problem in identifying the origin of packets. In Layer 2 networks, data frames are forwarded based on MAC (Media Access Control) addresses, lacking the clear routing identifiers found in Layer 3 networks. This makes it difficult for the master router in a home network to determine which slave router a packet originated from. This predicament directly prevents users from setting differentiated management policies for different slave routers. For example, users might want to set stricter internet access management, timed disconnections, and website isolation for slave routers connected to children's learning devices; or assign higher network priority to slave routers connected to office equipment to ensure stable transmission of work data. But because the master router cannot identify which slave router a packet originated from, these refined management policies based on slave routers cannot be effectively implemented. Summary of the Invention

[0005] Optionally, the process of the master route obtaining information about all slave routes in the mesh network includes the following steps: The master route obtains the device models of all the slave routes in the mesh network; The master router obtains the media access control addresses of all the slave routers; The master route establishes a first mapping relationship between the media access control address of the same slave route and the device model.

[0006] Optionally, the process of the master route generating a unique number for all the slave routes includes the following steps: The master router obtains the media access control addresses of all the slave routers; All media access control addresses are arranged in ascending order by the main route; The primary route generates a unique number for all the secondary routes according to the arrangement order; The master route establishes a second mapping relationship between the media access control address and the unique number of the same slave route.

[0007] Optionally, the process of the master route sending the unique number to the corresponding slave route includes the following steps: The master router obtains a second mapping relationship between the media access control address of the slave router and the unique number; According to the second mapping relationship, the master route sends the unique number to the slave route corresponding to the media access control address.

[0008] Optionally, the step of embedding the corresponding differential service code point value in its own packet based on the unique number includes the following steps: The unique number issued by the main route is obtained from the route; The differential service code point value is generated from the route based on the unique number; The message generated by itself is obtained from the route; Set the differential service code point value in a preset field of the message; The data packet containing the message is forwarded to the main route.

[0009] Optionally, the main route obtaining the differential service code point value in the packet includes the following steps: The master route receives the message sent by the slave route; Parse the differential service code point value in the message.

[0010] Optionally, the main route executes a preset rule action based on the differential service code point value, including the following steps: Retrieve the preset firewall rule base; Search the firewall rule base for rule actions that match the differential service code point value; The rule action is executed based on the matching result.

[0011] According to a second aspect of the present invention, a mesh network routing message identification device is provided, comprising: The information acquisition module is used by the main router to acquire information about all slave routers in the mesh network; The number generation module is used by the master route to generate a unique number for all the slave routes; The numbering distribution module is used by the master route to distribute the unique number to the corresponding slave route; The point value embedding module is used to embed the corresponding differential service code point value into the sub-router's own packet according to the unique number; A message acquisition module is used for the main router to acquire messages sent by the secondary router; Point value acquisition module, used by the main router to acquire the differential service code point value in the packet; The action execution module is used by the main router to execute preset rule actions based on the differential service code point value.

[0012] According to a third aspect of the present invention, an electronic device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of any of the preceding methods.

[0013] According to a fourth aspect of the present invention, a storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the methods described above.

[0014] The technical solution provided by this invention brings at least the following beneficial effects: This application provides a method for identifying slave router packets in a mesh network. This method transforms the "physical topology invisible" Layer 2 broadcast domain into a "logical topology visible" "lightweight policy domain." Layer 2 forwarding originally only recognized MAC addresses and did not remember "who is my downstream slave router," so the master router treated all frames within the same VLAN "equally." This invention injects a 6-bit field—the DSCP (Differential Service Code Point) in the IP header—into the frame. This field is not rewritten by switches within the Layer 2 network segment, but can be read by the master router's Layer 3 interface, thus smuggling "topology information" into the "quality of service label." The process can be viewed as a "lightweight signaling + implicit tunneling": Signaling phase—The master router collects the MAC, SN, BSSID, and other identifiers of slave routers through existing Mesh control protocols, dynamically assigns unique numbers, and then feeds them back to the "local policy database" of each slave router. This number occupies only 6 bits, which precisely maps to the low bits of the DSCP, requiring no additional bytes. Data Phase – When a router forwards a terminal frame, it hits an "outbound policy": all uplinks bridging the local machine are written to the DSCP with the specified number; the terminal is unaware of this and continues with the existing DHCP and NAT processes. Identification Phase – After receiving a frame on its Layer 3 interface, the master router first checks the DSCP, then the "number → slave router → user policy" mapping table, instantly restoring the "indiscriminate MAC frame" to a "flow with topology intent." Since the DSCP is naturally recognized by modules such as LinuxTC, hardware QoS, iptables, and nftables, subsequent differentiated actions (rate limiting, network disconnection, remarking, rerouting) can directly reuse existing hooks without requiring additional protocol stack patches. The entire mechanism involves zero VLANs, zero tunnels, and zero extra packets. It uses "coloring along the path" to divide the Layer 2 broadcast domain into N policyable logical chains, resolving the fundamental contradiction that "without seeing the source, fine-grained management is impossible." In summary, the ability to quickly and accurately determine the source of a packet from a secondary router, and to set different priorities and manage internet access restrictions for different secondary routers, is of vital practical significance for ensuring home network security, improving the smart home user experience, and optimizing home network management.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Figure 1 The illustration shows a flowchart of a mesh network method for identifying routing messages applicable to embodiments of the present invention.

[0020] See Figure 1 This invention provides a method for identifying routing packets in a mesh network, the method comprising the following steps: S1: The master route obtains information about all slave routes in the mesh network; For example, the process of the master route obtaining information about all slave routes in the mesh network includes the following steps: The master route obtains the device models of all the slave routes in the mesh network; The master router obtains the media access control addresses of all the slave routers; The master route establishes a first mapping relationship between the media access control address of the same slave route and the device model.

[0021] In this embodiment, the master router connects to each slave router through a wireless mesh network and automatically obtains relevant information of all slave routers in the wireless mesh network, including the device model and media access control address of all slave routers. Then, the master router establishes a mapping relationship between the media access control address and the device model of each slave router.

[0022] S2: The master route generates a unique number for all the slave routes; For example, the process of the master route generating a unique number for all the slave routes includes the steps of: The master router obtains the media access control addresses of all the slave routers; All media access control addresses are arranged in ascending order by the main route; The primary route generates a unique number for all the secondary routes according to the arrangement order; The master route establishes a second mapping relationship between the media access control address and the unique number of the same slave route.

[0023] In this embodiment, each slave route corresponds to a Media Access Control (MAC) address, and this MAC address is unique from all other MAC addresses. All MAC addresses are arranged in ascending order, thus arranging all slave routes accordingly. The master route then generates a unique number for each slave route, establishing a one-to-one mapping between this unique number and the slave route's MAC address.

[0024] S3: The master route sends the unique number to the corresponding slave route; For example, the process of the master route sending the unique number to the corresponding slave route includes the following steps: The master router obtains a second mapping relationship between the media access control address of the slave router and the unique number; According to the second mapping relationship, the master route sends the unique number to the slave route corresponding to the media access control address.

[0025] In this embodiment of the application, each slave router has a unique media access control address and a unique number, and the mapping relationship between the two is also unique. Therefore, when the master router sends a unique number to the slave router, the master router sends the generated number to the corresponding slave router according to the media access control address, clearly informing each slave router of its assigned number, and ensuring that the slave router can receive and store the number information.

[0026] S4: Based on the unique number, the sub-router embeds the corresponding differential service code point value into its own message; For example, the step of embedding the corresponding differential service code point value in its own packet based on the unique number includes the following steps: The unique number issued by the main route is obtained from the route; The differential service code point value is generated from the route based on the unique number; The message generated by itself is obtained from the route; Set the differential service code point value in a preset field of the message; The data packet containing the message is forwarded to the main route.

[0027] In this embodiment of the application, after receiving the number set by the master route, the slave route processes all Internet access packets forwarded by the Layer 2 bridge and embeds the differential service code point value corresponding to its own number into the packet, so that the packet carries information that uniquely identifies its source slave route.

[0028] Specifically, the user-space daemon of the primary router receives the configuration from the primary router, parses it to generate an internal configuration structure, and transmits the configuration to the kernel module via an inter-process communication protocol. After receiving the inter-process communication message, the kernel module updates the differential service code point value mapping table and activates the network protocol stack packet identification function. When a packet enters the forwarding process from the primary router, the packet identification program sets the differential service code point value to the TOS (Type of Service) field of the packet, completes packet tagging, and then forwards the packet to the primary router.

[0029] S5: The master router obtains the message sent by the slave router; In this embodiment of the application, after the primary route completes message tagging, it forwards the data packet to the primary route.

[0030] S6: The main route obtains the differential service code point value in the message; For example, the main route obtaining the differential service code point value in the packet includes the following steps: The master route receives the message sent by the slave route; Parse the differential service code point value in the message.

[0031] In this embodiment of the application, the main router receives a message with a differential service code point value sent from the secondary router and parses the differential service code point value in the message.

[0032] S7: The main router executes a preset rule action based on the differential service code point value.

[0033] For example, the main route executes a preset rule action based on the differential service code point value, including the following steps: Retrieve the preset firewall rule base; Search the firewall rule base for rule actions that match the differential service code point value; The rule action is executed based on the matching result.

[0034] In this embodiment of the application, the main router selects a rule action that matches the differential service code point value from a pre-defined firewall rule base, and executes the corresponding rule action according to the matching result, such as blocking access requests, application rate limiting, or filtering access to specific domain names.

[0035] like Figure 2 This application provides a mesh network routing message identification device, comprising: Information acquisition module 10 is used by the main router to acquire information about all slave routers in the mesh network; Number generation module 20 is used by the master route to generate unique numbers for all the slave routes; Numbering module 30 is used for the master route to send the unique number to the corresponding slave route; The point value embedding module 40 is used to embed the corresponding differential service code point value into the sub-router's own packet according to the unique number; The message acquisition module 50 is used for the main router to acquire the messages sent by the slave router; Point value acquisition module 60 is used for the main router to acquire the differential service code point value in the packet; The action execution module 70 is used for the main router to execute preset rule actions based on the differential service code point value.
