The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0048] Before describing the embodiments of the present application in detail, some nouns and terms involved in the embodiments of the present application are first described. The nouns and terms involved in the embodiments of the present application are subject to the following explanations.

[0049] SOA is a software architecture model that organizes and provides application functions through services. In the automotive industry, SOA is widely used in the development of in-vehicle software systems to support the integration and interaction of various functions and services.

[0050] Scalable service-oriented middleware over IP (SOME / IP) is an IP-based communication protocol stack, especially suitable for distributed systems in the automotive field. It aims to provide scalable service-oriented middleware to support communication and interaction between various electronic control units (ECUs) inside the car.

[0051] The SOME / IP protocol stack provides a flexible communication mechanism that supports message publishing and subscription, as well as service discovery and invocation. It enables efficient message transmission and data exchange in the internal network of the car, allowing different software modules to work together and provide complex car functions. Overall, the SOME / IP protocol stack plays an important role in realizing the service-oriented architecture and communication within the car, and provides a reliable solution for the development and integration of automotive software systems.

[0052] The number of stacks (also called the number of client services) in the SOME / IP protocol stack usually varies according to the specific implementation and application requirements, so there is no fixed standard value. In the SOME / IP protocol stack, the number of client services is usually determined by the application requirements and system design. Each service corresponds to a service interface, so the number of services in the stack depends on the number of services and functions required in a specific automotive application. Usually, the number of services in the stack is determined based on the functional and module divisions within the car. These services may cover functions such as diagnostics, control, communication, etc. In actual development, engineers need to determine the number of services in the stack based on the system design and application requirements, and configure and program accordingly. Therefore, to determine the number of stacks in the SOME / IP protocol stack, it is necessary to analyze and make decisions based on the specific application scenario and system design.

[0053] In related technologies, with the development of intelligent and connected vehicles, the transformation of automotive electronic architecture from distributed to integrated and then to domain-controlled, and the diversification of hardware and software of vehicle controllers, Ethernet has gradually become the backbone network for vehicle communications. In-vehicle Ethernet is relatively complex and involves a lot of protocol content. Usually, the protocol defines a set of rules and mechanisms to ensure effective communication between devices. The protocol stack is the behavior of the protocol implemented by software.

[0054] The number of service groups in the SOME / IP protocol stack includes the number of clients and servers, which is determined by the service groups in the arxml deployment. However, due to the early warning of the performance limitations of the protocol stack, the architecture is expected to reduce the number of service groups defined by signals during the model deployment process. However, during the iteration of the protocol stack version, it was found that the stack gradually increased, which eventually affected the system compilation.

[0055] In view of this, a solution is provided in an embodiment of the present application to reduce the number of client stacks generated so that the system can compile and integrate normally, subscribe to signals, and complete the joint adjustment point on schedule.

[0056] The stack overload optimization method provided in the embodiment of the present application relates to the field of vehicle-mounted intelligent technology. The stack overload optimization method provided in the embodiment of the present application can be applied to a terminal, can also be applied to a server, and can also be software running in a terminal or a server. In some embodiments, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, and a vehicle-mounted terminal, etc., but is not limited to this; the server side can be configured as an independent physical server, or it can be configured as a server cluster or a distributed system composed of multiple physical servers, and can also be configured to provide cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms and other basic cloud computing services. The cloud server, the server can also be a node server in the blockchain network; the software can be an application of the optimization method for implementing stack overload, etc., but is not limited to the above forms.

[0057] The present application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform specific tasks or implement specific abstract data types. The present application can also be practiced in distributed computing environments, in which tasks are performed by remote processing devices connected through a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0058] It should be noted that in each specific implementation of the present application, when it comes to the need to perform relevant processing based on data related to user identity or characteristics such as user information, user behavior data, user historical data, and user location information, the user's permission or consent will be obtained first, and the collection, use, and processing of these data will comply with relevant laws, regulations, and standards. In addition, when the embodiment of the present application needs to obtain the user's sensitive personal information, the user's separate permission or consent will be obtained through a pop-up window or by jumping to a confirmation page. After clearly obtaining the user's separate permission or consent, the necessary user-related data for the normal operation of the embodiment of the present application will be obtained.

[0059] Figure 1 It is an optional flow chart of the stack overload optimization method provided by the embodiment of the present application; Figure 1 The method may include but is not limited to steps S100 to S400.

[0060] Step S100, determining a stack signal correspondence table according to the service signal corresponding to each client stack;

[0061] Step S200, establishing a server application, simulating the server to initiate a subscription, and determining the subscription result of the client;

[0062] Step S300, determining the subscription signal of each client stack according to the subscription result and the stack signal correspondence table;

[0063] Step S400, screening the client stack according to the function matrix and the number of subscription signals, and performing a compilation operation; the function matrix is ​​established according to the demand.

[0064] The embodiment of the present application identifies the service signal of each stack and sorts out the SWC (service signal of software component) corresponding to each stack one by one. For example, referring to Figure 2 A stack signal correspondence table of an embodiment is shown; wherein the first column is the name of the stack in the protocol stack, and the second column is the corresponding service signal. Then, corresponding to the signal subscription situation included in the current version, a server-side application is built to simulate the behavior of the server, determine the subscription result of each client, and then determine the subscription signal of each client stack. According to the number of subscription signals of each client stack, priority judgment is made, and the client stacks with a small number of subscription signals are screened out, and compilation operations are performed; the function matrix is ​​established according to demand. Specifically, the subscription signal in the embodiment of the present application is used to characterize a successful subscription and a service signal that is successfully transmitted by the signal protocol stack.

[0065] The embodiment of the present application solves the compilation problem: by adjusting the number of stacks, ensuring that the number of service groups does not exceed the limit, errors and warnings that occur during the compilation process are solved. This can ensure that the software will not fail to compile due to exceeding the limit when it is built, thereby improving the stability and reliability of the software. The embodiment of the present application improves system performance: limiting the number of service groups can avoid excessive resource occupation and system load, thereby improving the performance of the system. By optimizing the number of service groups, memory and processor resources can be managed more effectively, the delay and response time of the system can be reduced, and the overall performance of the system can be improved. The embodiment of the present application simplifies maintenance and debugging: controlling the number of service groups can simplify the maintenance and debugging process of the system. By reducing the number of service groups, the complexity of the system is reduced, making the system easier to understand and manage. In addition, fewer service groups also mean less code and configuration that need to be maintained, reducing the possibility of potential errors and problems. The embodiment of the present application improves system scalability: by reasonably controlling the number of service groups, the scalability of the system can be improved. Avoiding too many service groups can maintain the flexibility of the system, making the system easier and more reliable in future expansion and upgrade processes. The embodiment of the present application optimizes resource utilization: by limiting the number of service groups, the utilization of resources can be better optimized. The system can utilize limited resources more effectively and ensure more reasonable and balanced resource allocation, thereby maximizing the efficiency and performance of the system.

[0066] In summary, the embodiment of the present application can effectively solve the problem of exceeding the limit of the number of service groups by adjusting the number of stacks of the SOME / IP protocol stack, bringing many beneficial effects, including improving system stability, performance, maintainability, scalability and resource utilization efficiency. These effects help ensure the smooth operation and sustainable development of the system.

[0067] In some embodiments, reference Figure 3 As shown, the method provided in the embodiment of the present application performs screening processing on the client stack according to the function matrix and the number of subscription signals; including:

[0068] Step S410, arranging the subscription signals in order from small to large or from large to small in number, and matching the subscription signals with the function signals in the function matrix in order;

[0069] Step S420: If the current subscription signal does not match the functional signal, it is determined that the current subscription signal is a useless signal, and the client stack corresponding to the current subscription signal is filtered out.

[0070] In some possible implementations, the number of stack signals (i.e., subscription signals in the embodiments of the present application) is obtained and sorted. Exemplarily, the SWC subscribed in the stack with less signal quantity can be retrieved with the function matrix first, and after matching the required signal, the useless SWC service is screened out. Exemplarily, in a specific embodiment, after obtaining the subscription signal of each client stack, the number of subscription signals contained in each client stack as shown in Table 1 is sorted, wherein there is only one subscription signal corresponding to 44 client stacks, and the 44 client stacks are first screened.

[0071] The number of signals the stack contains Number 1 44 2 11 3 2 4 4 5 2 5 or more 7

[0072] Table 1

[0073] It is understood that the function matrix can be determined according to the needs, referring to Figure 4 A form of a function matrix is ​​shown, in which the third column is the signal corresponding to the function. If the subscription signal can match the function signal, the current subscription signal is determined to be a useful signal; otherwise, if the current subscription signal does not match the function signal, the current subscription signal is determined to be a useless signal, and the client stack corresponding to the current subscription signal is filtered out.

[0074] In some embodiments, the method provided in the embodiments of the present application establishes a server application, simulates the server to initiate a subscription, and determines the subscription result of the client, including:

[0075] Create a server application and establish a connection between the server and the client;

[0076] The server sends a subscription message to the client and receives the subscription result returned by the client.

[0077] In some possible implementations, after establishing the stack signal correspondence table, the embodiment of the present application performs signal simulation through the server application to determine the subscription result of each client.

[0078] The following is a simple TCP-based sample code to simulate the server initiating a subscription:

[0079]

[0080]

[0081] In some embodiments, the method provided in the embodiments of the present application determines the subscription signal of each client stack according to the subscription result and the stack signal correspondence table, including:

[0082] Determine, according to the subscription result, the first signal successfully transmitted by the signal protocol stack;

[0083] The first signal is matched with the service signal in the stack signal correspondence table to determine the subscription signal of each client stack.

[0084] In some possible implementations, based on the above example code embodiments for TCP, refer to Figure 5 The signal subscription result initiated by the server is shown. Wherein Service...up means that the subscription is successful, and there is no problem with the server subscription. Message is the result returned by the client. Default means that the client returns a failure, and OK means that the client returns a success. In the above embodiment, 6 signals are successfully subscribed to the server. Among these 6 signals, 2 signal protocol stacks fail to transmit, and 4 succeed. The embodiment of the present application needs to identify these completion signals separately, match them with the service signals in the stack signal corresponding table, determine the subscription signal of each client stack, and update Figure 2 The stack signal correspondence table shown in the figure, the updated stack signal correspondence table can be found in Figure 6 shown.

[0085] In some embodiments, reference Figure 7 , the method provided in the embodiment of the present application further includes:

[0086] Step S500, sending a second signal through the server, and receiving a second result returned by the client;

[0087] Step S600, filtering the third signal of successful subscription from the second result;

[0088] Step S700: If the third signal is consistent with the second signal, it is determined that the protocol stack has been integrated.

[0089] In some possible implementations, the embodiment of the present application determines the protocol stack transfer process through the following steps:

[0090] S11, confirming the sending of the server signal, that is, the second signal sent;

[0091] S12, intercepting the returned result, i.e., the second result;

[0092] S13, collecting the subscription success signal of the server (i.e., the third signal), if it is different from the second signal in S11, it means that the base of the sending end is not integrated;

[0093] S14. Distinguish the results returned by the client and obtain an OK signal (i.e., a subscription signal).

[0094] In some embodiments, the method provided by the embodiments of the present application further includes:

[0095] Bind the server address and port;

[0096] Listen for and establish connections between the server and the client.

[0097] In some embodiments, the method provided in the embodiments of the present application refers to Figure 8 As shown, it also includes:

[0098] Step S110, establishing a service signal mapping table; the service signal mapping table is a correspondence between ID numbers and service signals;

[0099] Step S120: determining the service signal in each client stack according to the identified ID number.

[0100] In the embodiment of the present application, the corresponding signal is identified in the stack by the group ID and the event ID. Referring to the code in the embodiment shown below:

[0101]

[0102] Exemplarily, the embodiment of the present application may establish a mapping table of service signals, which is implemented using a dictionary in the example:

[0103]

[0104] In some embodiments, the method provided by the embodiments of the present application further includes:

[0105] Get the accumulated duration;

[0106] If the accumulated duration is equal to the preset duration, a server application is established to simulate the server initiating a subscription, determine the client's subscription result, and recalculate the accumulated duration; the accumulated duration is the duration since the last simulated server initiated a subscription, and the preset duration is the duration between two simulated server-initiated subscriptions.

[0107] The embodiment of the present application can set specific values ​​of the cumulative duration and the preset duration according to actual needs to adjust the period of the simulated server to initiate the subscription. The preset duration can be set to real time, a fixed local time period, or a non-fixed time period. According to the frequency of use or importance of the system in different time periods, time periods of different interval lengths are set to meet system requirements while providing a variety of choices.

[0108] The embodiments of the present application can automatically identify and process useless signals, ensure that only necessary signals and functions are included in the stack, and improve the efficiency and performance of the system. The embodiments of the present application can automatically optimize the stack configuration to ensure compliance with the limitations of the protocol stack and avoid problems caused by the number of stacks exceeding the limit.

[0109] The embodiments of the present application ensure the accuracy and reliability of the automated method, avoid misjudgment or omission of useless signals, and cause problems with system stability and reliability. The embodiments of the present application ensure that the process of automated optimization of stack configuration does not affect system functions and performance, and ensure that the system can still operate normally and meet requirements after optimization. The embodiments of the present application can improve the efficiency of system development and maintenance through automated methods, reduce errors and omissions in manual operations, thereby improving the stability and reliability of the system and reducing development costs and risks.
