[0058] In a specific embodiment, a service-based communication device based on a time-sensitive network includes a management node, several clients (ie, device 100 ) and several servers (ie, device 200 ); wherein, The management node includes a registration module and a third network transmission configuration module.
[0059] The client includes a service information sending module 110, a first client service-oriented communication component 120, a second client service-oriented communication component 130 and a first network transmission configuration module.
[0060] The server includes a service registration sending end 210, a server service communication component 220 and a second network transmission configuration module.
[0061] Lightweight design: low communication overhead, using concise and easy-to-parse JSON data format to avoid lengthy XML or complex binary formats; supporting data compression to reduce the amount of data transmitted over the network and improve transmission efficiency; concise protocol header, simple protocol header information to reduce unnecessary metadata transmission; easy to integrate and deploy, does not rely on any third-party libraries, and is easy to integrate into various applications.
[0062] Client request: Synchronous RPC request will block the current process until receiving a response from the server or timing out; asynchronous RPC request uses asynchronous callback method, the client does not wait for the server to respond, and processes the result returned to the server in the callback function.
[0063] Network transmission configuration (i.e., first network transmission configuration module, first network transmission configuration module, and first network transmission configuration module) The network transmission configuration provides the TSN communication capability for nodes. Mission-critical areas have precise time requirements for network transmission. The TSN network aims to make the non-deterministic Ethernet have deterministic minimum latency, emphasizing ultra-low latency and high availability of transmission. Key technologies include time and synchronization, data adjustment and traffic shaping.
[0064] Timing and synchronization technology: TSN network ensures the time synchronization of each node in the network by using GPTP (Precision Time Protocol). This technology supports the time synchronization compatibility of different TSN devices and enhances the robustness of the clock synchronization system, allowing seamless switching to redundant clock sources when the main clock source fails. Through the GPTP protocol, the master clock in the TSN network regularly sends synchronization messages, and each node adjusts its own clock to synchronize with the master clock after receiving the message. This ensures that each node in the entire network has a common time reference.
[0065] Data scheduling and traffic shaping: By running scheduling algorithms such as 802.1Qbu and 802.1Qbv, TSN can shape the transmitted data to ensure that the delay of the data flow in different scenarios is limited to a controllable range. Using specific scheduling algorithms, such as 802.1Qbu and 802.1Qbv, TSN can shape the data flow and give priority to the transmission of key data, thereby ensuring that applications with high real-time requirements are met and the delay is controlled within a predetermined range.
[0066] Service-based communication components (i.e., first client service-based communication component 120, second client service-based communication component 130, and server service-based communication component 220) The service-oriented communication component consists of an RPC module and a publish-subscribe module. The component adopts a lightweight design and has the characteristics of simple architecture, small resource usage, and fast service response speed.
[0067] like Figure 5 As shown, the message header occupies a total of 24 bytes, including the message size, method length, method identifier, sequence number, message priority, and status code. The protocol header information is simple, reducing unnecessary metadata transmission.
[0068] like Figure 6 As shown, the process of RPC request is shown: a) The client serializes the request data, adds the request to the unresponse queue, and sends the request message; b) The server parses and deserializes the request data and searches the service mapping table for the corresponding service call; c) The server serializes the response data and sends a response message; d) The client parses and deserializes the response data and performs the next step based on the response data.
[0069] like Figure 7 As shown, the process of publishing and subscribing is shown: a) The client encapsulates the subscription topic and sends it to the server; b) The server adds the subscription topic to the subscription list (the server creates a subscription list for each connected client and queries the subscription list to see if there is a corresponding topic when publishing); c) The server serializes the published data and sends a published message; d) The client parses the published message and calls the publish-subscribe callback function for further processing.
[0070] In addition, the registration center can store the address information of the service provider and the attribute information related to service release. When the service is started, the relevant information is registered with the service registration unit. The client actively queries and obtains the address information of the service provider through the service discovery unit to realize service discovery. The registration center should monitor the effectiveness of the service and regularly check the health status of the registered service through the heartbeat detection unit. When the service is redeployed due to external factors, the invalid service address information should be removed from the registration center in a timely manner, and the valid service information should be updated. In a specific embodiment, Figure 8 As shown in the figure, it is a schematic diagram of the overall structure of service-oriented communication based on time-sensitive network. Its specific workflow is divided into: System initialization and service registration a) TSN network transmission configuration: The TSN network scheduler configures the priority, time window, and transmission plan of the TSN flow for each service based on the time sensitivity and bandwidth requirements of the service to ensure that the network transmission of different services meets the latency and reliability requirements.
[0071] b) Registration center initialization: When the system starts, the registration center module is initialized first, providing a centralized registration and query platform for each service node.
[0072] c) Service node registration: When each service node is started (such as Node B (i.e., the server)), it registers its service information with the registration center, including the service name, network address, port number, and TSN required parameters such as latency and bandwidth. The registration center stores this information in the service directory for subsequent queries.
[0073] Service-oriented communication a)RPC: When a node (such as node A (i.e., client) needs to call the service of another node (such as node B), node A first queries the registration center for the network address and TSN parameters of node B. After obtaining the TSN parameters of node B, node A selects the optimal TSN path based on these parameters to send a request to node B. After receiving the request, node B processes and generates a response, and finally returns the result to node A through the TSN network.
[0074] b) Publish and subscribe: Like RPC, when node A needs the published data of node B, node A first queries the network address and TSN parameters of node B, and sends subscription information such as TOPIC and subscription frequency to node B. After node B generates new data or events, it publishes the data or event message to node A through the TSN network.
[0075] Service health check and status monitoring a) Heartbeat detection: The registration center regularly sends heartbeat detection requests to each service node through the TSN network to monitor the operating status of each node.
[0076] Fault handling: If a service node fails to respond to a heartbeat request on time, the registry will determine that the node may be faulty and mark its status as unavailable. At the same time, the registry will notify related dependent services or subscribers.
[0077] Through the above-mentioned service-oriented communication method and device based on time-sensitive network, on the one hand, the first service-oriented communication component and the first service-oriented communication component are constructed to provide a service interface for the upper-layer application; through the first network transmission configuration module and the second network transmission configuration module, it is ensured that the upper-layer application can transmit information through TSN. Construct a registration center module to provide service registration and service discovery, so that access between services is more flexible. On the other hand, TSN technology can be provided to upper-layer applications in a service-oriented manner to achieve efficient and flexible management and scheduling of TSN network resources, making application development more concise.
[0078] Regarding the device in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.
[0079] It should be noted that although several modules or units of the device for action execution are mentioned in the above detailed description, this division is not mandatory.
