Description

Technical Field

[0001] The present invention relates to the technical field of data communication, and in particular to a verification method, device, electronic equipment and storage medium for a static configuration table. Background Art

[0002] With the vigorous development of SOA (Service-Oriented Architecture), intelligent driving, smart cockpit, OTA (Over-The-Air) and other technologies in the automotive field, Ethernet has become one of the most widely used buses in the automotive field. And with the continuous transformation of electronic and electrical architecture from traditional bus type to distributed and centralized type, Ethernet may become the only transmission medium for vehicle communication. Unlike traditional Ethernet, the nodes in the car are generally set to static IP (Internet Protocol) addresses. In order to reduce the delay caused by mutual recognition between the communicating parties and the waste of bandwidth resources caused by undefined node address connections, the nodes in the car are not allowed to learn dynamically and use static configuration tables. During the communication process, only the addresses that meet the configuration of the static configuration table can communicate normally.

[0003] Due to the complexity of vehicle Ethernet services, different services may be deployed in different virtual LANs, each virtual LAN may carry different services or services, different services may be provided by different partners or suppliers, and these nodes may be distributed in different geographical locations or network environments. Since the static configuration table is a manually configured address mapping relationship, it will not be updated through dynamic configuration requests. If an error occurs in the static configuration table, the device will directly use the wrong address for communication instead of correcting the error through dynamic configuration requests.

[0063] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] Different from the traditional Ethernet environment, in modern vehicle networks, especially Ethernet-based communication systems, static IP addresses are usually selected for communication. Each node (such as vehicle control unit, sensor, actuator, etc.) is pre-configured with a static IP address, which means that before the communication starts, the node already knows the other party's IP address, so there is no need to dynamically obtain the IP address through the dynamic host configuration protocol or other mechanisms. In order to reduce the delay caused by mutual identification between the communicating parties and the waste of bandwidth resources caused by undefined node address connections, the in-vehicle nodes do not allow ARP (Address Resolution Protocol) dynamic learning, and use ARP static configuration table.

[0065] However, when errors occur in the configuration information in the static configuration table, they are often only revealed when the relevant business is tested and verified. At this time, correcting the ARP static configuration table will inevitably affect the advancement of the business. Figure 1 , shows a flowchart of a method for verifying a static configuration table provided in an embodiment of the present invention, the method is applied to an Ethernet controller of a vehicle, the Ethernet controller includes a test port, and specifically may include the following steps:

[0066] In one embodiment of the present invention, it is first necessary to connect the control end and the prototype under test through an adapter cable. The control end can be a port of a PC (Personal Computer) that can control the prototype under test. The prototype under test can select an Ethernet controller (Ethernet Controller) or a switch, etc. The prototype under test includes a test port for verification.

[0067] Step 101, obtaining a static configuration table of a test port, the static configuration table including configuration information of the test port;

[0068] After connecting the control end and the tested sample, the ARP static configuration table configured at the test port is obtained. The ARP static configuration table configures the configuration information corresponding to the test port, such as IP information, MAC (Media Access Control) information and VLAN (Virtual Local Area Network) information.

[0069] Step 102, modifying the local network configuration according to the configuration information to obtain the target network configuration;

[0070] In the embodiment of the present invention, after obtaining the ARP static configuration table, it is necessary to traverse the configuration information in the ARP static configuration table, and modify the configuration information in the local network configuration to the configuration information in the ARP static configuration table to obtain the modified target network configuration.

[0071] Local network configuration refers to the network configuration of the control end.

[0072] Step 103: Verify the test port according to the target network configuration and generate a first verification result for the static configuration table.

[0073] In an embodiment of the present invention, a series of checks are performed on the test port using the modified target network configuration, such as ARP table entry check, network connectivity check, data packet capture and analysis, switch configuration check, security check, fault simulation and other types of check methods, but the present invention is not limited to this.

[0074] In the embodiment of the present invention, modifying the local network configuration according to the configuration information in step 102 includes:

[0075] Obtain original configuration information in the local network configuration; modify the original configuration information to the configuration information of the test port.

[0076] For example: Modify the IP address configured in the local network to make it consistent with the IP address of the test port. The IP address is used to identify the unique address of the device in the network, and is usually divided into two versions: IPv4 and IPv6. Modify the MAC address configured in the local network to make it consistent with the MAC address of the test port. The MAC address is used to identify the unique address of the network interface card, and is usually represented by a 48-bit binary number, which is divided into two parts: the manufacturer identification and the device identification. Modify the VLAN information configured in the local network to make it consistent with the VLAN information of the test port.

[0077] In the embodiment of the present invention, the local network configuration of the control end has original configuration information, and the original configuration information of the local network configuration needs to be modified into the configuration information of the test port.

[0078] In the embodiment of the present invention, step 103 verifies the test port according to the target network configuration, which means that the test port is firstly forward verified. The specific steps are as follows:

[0079] A forward request message is sent to the test port. In one embodiment, the forward request message may be a PING (Packet Internet Groper) message. The PING message is a general term for ICMP Echo Request messages and ICMP Echo Reply messages, and is used to test the connectivity between two devices in the network. The control end sends an ICMP Echo Request forward message to the test port, and determines whether an ICMP Echo Reply message returned by the test port can be received.

[0080] According to the response of the test port to the forward request message, determine whether there is incorrect configuration information in the configuration information of the static configuration table; when receiving the positive response message fed back by the test port to the forward request message, determine that there is no incorrect configuration information in the configuration information of the static configuration table; when not receiving the positive response message fed back by the test port to the forward request message, determine that there is incorrect configuration information in the configuration information of the static configuration table.

[0081] In the embodiment of the present invention, when performing a forward check, since the configuration information in the local network configuration is the configuration information of the test port at this time, sending a forward request message is equivalent to checking whether the configuration information in the ARP static configuration table has error information. If the response information (i.e., PONG message) returned by the test port can be received, it can be determined that the configuration information in the ARP static configuration table has no error information. On the contrary, if the response information (i.e., PONG message) returned by the test port is not received, it can be determined that the configuration information in the ARP static configuration table has error information.

[0082] In an embodiment of the present invention, the response message returned by the test port may include: a correct response, an error response and a timeout without response. For an error response and a timeout without response, the step of sending a PING message may be repeated. If the result does not change after sending the PING message multiple times, it can be determined that error information has appeared in the configuration information in the ARP static configuration table.

[0083] In the embodiment of the present invention, a series of checks are performed on the test port using the modified target network configuration, which may also include performance checks. The specific steps are as follows:

[0084] In the embodiment of the present invention, the PING message sent and the PONG message received during verification may carry a timestamp, and the timestamp is used to indicate the sending time of the PING message and the receiving time of the PONG message.

[0085] Recording the first time information of sending a positive request message (PING message) to the test port and the second time information of receiving a positive response message (PONG message);

[0086] Calculate the message response time of the test port according to the time difference between the first time information and the second time information;

[0087] Evaluate the performance of the static configuration table based on the message response time.

[0088] In an embodiment of the present invention, when receiving a positive response message fed back by the test port for a positive request message, after determining that the configuration information of the static configuration table does not contain the erroneous configuration information, it also includes performing a reverse check on the test port, and the specific steps are as follows:

[0089] Modify part of the configuration information in the static configuration table to generate an abnormal static configuration table. Since only part of the configuration information in the static configuration table is modified, the abnormal static configuration table contains unmodified configuration information and modified abnormal configuration information, wherein the unmodified configuration information is the same as the configuration information of the test port, and the abnormal configuration information is different from the configuration information of the test port.

[0090] The local network configuration is modified according to the abnormal configuration information to obtain the abnormal network configuration. During reverse verification, the original configuration information in the local network configuration of the control end is modified to the abnormal configuration information in the abnormal static configuration table to obtain the abnormal network configuration for reverse verification.

[0091] Perform reverse verification on the test port according to the abnormal network configuration to generate a second verification result for the abnormal static configuration table. The steps of reverse verification are as follows:

[0092] A reverse request message is sent to the test port. In one embodiment, the reverse request message may be a PING message. When a reverse response message fed back by the test port in response to the reverse request message is received, unmodified information of the abnormal static configuration table is detected.

[0093] In an embodiment of the present invention, when performing a reverse check, since a forward check has been performed before, during the forward check process, a forward response message returned by the test port can be received after a PING message is sent to the test port, indicating that the configuration information in the static configuration table at this time can ensure two-way communication with the test port. However, there is another abnormal situation, that is, the configuration information at this time is "mandatory" to request a forward response message from the test port, rather than receiving a forward response message under normal circumstances. In order to eliminate such abnormal situations in the static configuration table of the present invention, it is necessary to reversely verify the static configuration table. During the reverse verification, the present invention does not modify all the configuration information in the static configuration table, but modifies the configuration information in the static configuration table to check whether the unmodified configuration information is mandatory information. The mandatory information in the present invention refers to information that does not wait for the response message sent by the test port to be received, but "mandatory" requests a response message from the test port. For example, there are configuration information A, configuration information B, configuration information C, configuration information D and configuration information E in the static configuration table. First, only configuration information A, configuration information B and configuration information C are modified to configuration information a, configuration information b and configuration information c, while configuration information D and configuration information E are not modified. That is, the abnormal configuration information generated at this time includes configuration information a, configuration information b, configuration information c, configuration information D and configuration information E. Based on the abnormal configuration information at this time, the local network configuration is modified to obtain an abnormal network configuration, and a reverse request message is sent to the test port with the abnormal network configuration. Since the abnormal network configuration at this time contains the abnormal configuration information, it is impossible to communicate normally with the test port, and thus It is impossible to receive a reverse response message from the test port. Therefore, if the response information returned by the test port, that is, the PONG message, can be received, then it can be determined that at least one of the configuration information D and the configuration information E is mandatory information. In order to thoroughly find out which configuration information is mandatory information, the configuration information D or the configuration information E can be modified to test them separately, so as to determine the configuration information that is mandatory information, modify it to new configuration information, and re-perform forward and reverse checks on the new configuration information until the modified new configuration information can receive the forward response message returned by the test port during the forward check, and cannot receive the reverse response message returned by the test port during the reverse check.

[0094] In an embodiment of the present invention, if no PONG message is received during forward verification, it indicates that an abnormal situation exists; if a PONG message is received during reverse verification, it indicates that an abnormal situation exists. The verification results of the forward verification and the reverse verification can be recorded and a verification report for the static configuration table can be generated based on this.

[0095] The first verification result is recorded, and a verification report for the static configuration table is generated.

[0096] In an embodiment of the present invention, the first verification result can be obtained from the test port, and the first verification result can be stored in a local or remote database for subsequent analysis and report generation. Extract key information from the collected first verification result, such as the duration used for this verification, whether a PONG message is received, etc. The tester can also select or create a suitable report template, and the report template is used to display the first verification result. The final verification report can be in PDF, HTML, Excel and other formats. The present invention does not specifically limit the display method, and the generated verification report can also be stored in a specified location, such as a local file system or cloud storage, and the verification report can be sent to relevant personnel via email, message system or other communication methods. For the second verification result, the present invention can also generate its corresponding verification report, and the specific steps refer to the process of generating the verification report from the first verification result.

[0097] The present invention obtains the static configuration table of the test port on the Ethernet controller, modifies the local network configuration according to the configuration information contained in the static configuration table, obtains the target network configuration, and finally verifies the test port according to the target network configuration to generate a first verification result for the static configuration table. The present invention sends a message for verification to the test port through the target network configuration, so as to quickly determine whether there is error information in the current static configuration table of the test port according to the response of the test port to the message, thereby avoiding the situation that the vehicle finds that error information appears in the static configuration table when conducting related business on the Ethernet, but the static configuration table cannot be updated through the dynamic configuration request.
