[0038] Example 1

[0039] This application provides a message tracing method based on an ARM embedded kernel.

[0040] See Figure 1 The packet tracing method based on the ARM embedded kernel includes steps S101-S106:

[0041] Step S101: Switch the gateway from normal mode to debug mode and configure debug parameters; the debug parameters include multiple debug levels and multiple packet matching conditions.

[0042] In this embodiment, switching the gateway from normal mode to debug mode can be done by entering a command line, a webpage, or TR069. For example, using the SSH or telnet command-line tool to connect to the gateway device, after connecting, enter administrator mode or superuser mode. In administrator mode, find the debugging-related options or commands, and enable debug mode according to the device's documentation or guide. Alternatively, you can obtain the IP address and port of TR069, open a browser (such as Internet Explorer, Chrome, etc.), enter the IP address and port number of TR069 to connect to TR069, enter the administrator's username and password, and after successful login, enter debug mode and enable debug mode.

[0043] In step S102, the ARM embedded kernel captures and analyzes all packets from multiple specific nodes to obtain packet analysis results.

[0044] In this embodiment, an Advanced Reduced Instruction Set Architecture (ARM) processor is used. After obtaining the analysis results, the analysis results are saved to the NAND flash memory. The basis for analyzing the packets can be the destination MAC or source MAC, destination IP or source IP, port, protocol, or VLAN ID.

[0045] Step S103: Based on the message matching conditions, determine from the message analysis results whether the target message has been captured within a preset time, and generate the corresponding target capture record.

[0046] In this embodiment, the message matching conditions are the destination MAC or source MAC, destination IP or source IP, port and protocol 5-tuple, matching VLAN information and information in any specific field in the message, such as domain name information in a DNS message; the preset time can be 5 seconds.

[0047] Step S104: Determine the target debugging level from the multiple debugging levels based on the debugging range.

[0048] In this embodiment, the debugging scope is the range of outputting debugging information of all nodes, a portion of the debugging information of a specified node, or a portion of the debugging information of a specified node by the technician; there are three debugging levels: the first debugging level means outputting debugging information of all nodes, the second debugging level means outputting debugging information of a portion of the specified nodes, and the third debugging level means outputting a portion of the debugging information of the specified nodes; the target debugging level is determined by selecting from multiple debugging levels.

[0049] Step S105: Set the gateway to the target debugging level, obtain the debugging information corresponding to the target debugging level, and send the debugging information and the target capture record to the cloud server.

[0050] In this embodiment, for example, the first level is determined as the target debugging level, and the debugging information of all nodes and the target capture record are sent to the cloud server.

[0051] In step S106, the cloud server analyzes the debugging information and the target capture record to generate a problem analysis report for each specific node.

[0052] In this embodiment, after the debugging information log and target capture record log are uploaded to the cloud server, the cloud server automatically and intelligently analyzes the logs and generates problem analysis reports for each specific node, which are then sent to the R&D personnel.

[0053] See Figure 2 Step S103 includes steps S1031-S1032:

[0054] Step S1031: If the target message is captured within the preset time, a success record is generated and the success record is saved to flash memory.

[0055] In this embodiment, if the target packet is captured within 5 seconds, a success record is generated and saved to the flash memory. The target packet is the destination MAC or source MAC, destination IP or source IP, port, protocol or VLAN ID, such as the port number of the HTTP service is 80, and the communication protocol used by the network packet is TCP, UDP, etc.

[0056] Step S1032: If the target message is not successfully captured within the preset time, a failure record is generated and the failure record is saved to the flash memory.

[0057] In this embodiment, the failure record can be: capture target: capture a specific type of HTTP message, preset time: 5 seconds; failure record content: capture time: March 15, 2023, 9:30 am.

[0058] In one embodiment, once the target message is captured, it is transmitted sequentially according to the communication connection order of the multiple specific nodes.

[0059] In this embodiment, the communication connection sequence of a specific node is, for example, from switch driver - SFP driver - wireless driver - VLAN driver - kernel protocol stack - routing forwarding node - Dynamic Host Configuration Protocol server (DHCP Server).

[0060] In one embodiment, the cloud server performs data preprocessing on the debugging information and the target capture record to obtain preprocessed data, analyzes the preprocessed data, and generates a message transmission diagram and a network anomaly report.

[0061] In this embodiment, the preprocessed data is analyzed, for example, a data flow diagram is generated based on the keywords of the preprocessed data: such as a flow diagram like sfp driver->vlan driver->kernel. If a specific node fails to capture the target packet, some error information is marked on the flow diagram.

[0062] In one embodiment, the cloud server performs data parsing and data cleaning on the debugging information and the target capture records.

[0063] In this embodiment, data parsing, for example, for structured debugging information and target capture records, the cloud server can use regular expressions or a text-based parser to extract the required fields and information; data cleaning, for example, the cloud server can delete duplicate data records, convert data types, remove noisy data, etc.

[0064] In one embodiment, the plurality of specific nodes include: a switch driver, an SFP driver, a wireless driver, a VLAN driver, a kernel protocol stack, a routing and forwarding module, and an upper-layer application.

[0065] In this embodiment, the upper-layer application is such as a DHCP server, DNS proxy, IGMP proxy, etc.

[0066] In one embodiment, the debugging levels include: a first level, a second level, and a third level; according to the first level, debugging information for all the nodes is output; according to the second level, debugging information for a portion of the specified nodes is output; and according to the third level, partial debugging information for the specified nodes is output.

[0067] In this embodiment, the output of some debugging information for a specified node includes: the current debugging time, whether the target message was successfully captured, whether the target message was not captured within the specified time, whether the message was discarded because it did not meet the specifications, or whether the message was returned because it did not meet the specifications.

[0068] The packet tracing method based on an ARM embedded kernel provided in this embodiment switches the gateway from normal mode to debug mode and configures debug parameters. These debug parameters include multiple debug levels and multiple packet matching conditions. The ARM embedded kernel captures and analyzes all packets from multiple specific nodes to obtain packet analysis results. Based on each packet matching condition, it determines whether a target packet was captured within a preset time from the packet analysis results, generating a corresponding target capture record. A target debug level is determined from multiple debug levels based on the debug range. The gateway is set to the target debug level, and the debug information corresponding to the target debug level is obtained. The debug information and target capture record are sent to a cloud server. The cloud server analyzes the debug information and target capture record, generating a problem analysis report for each specific node. When a problem occurs with the home gateway, it eliminates the need for on-site service from the operator's technicians; debugging can be performed remotely, minimizing the impact on users.
