[0033] The technical solution provided by this application is further described below with reference to the accompanying drawings and examples. It should be understood that the system structure and business scenarios provided in the examples of this application are mainly for illustrating possible implementation methods of the technical solution of this application and should not be interpreted as the sole limitation of the technical solution of this application. It is known to those skilled in the art that with the evolution of the system structure and the emergence of new business scenarios, the technical solution provided by this application is also applicable to similar technical problems.

[0034] It should be understood that the embodiments of the present application provide a communication solution based on a time-sensitive network. Since these technical solutions solve the same or similar problems, some repetitions may not be repeated in the following specific embodiments. However, these specific embodiments should be considered as having referenced each other and can be combined with each other.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. In the event of any inconsistency, the meanings described in this specification or the meanings derived from the contents recorded in this specification shall prevail. In addition, the terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application. In order to accurately describe the technical content in this application and to accurately understand the present invention, the following explanations or definitions are given for the terms used in this specification before describing the specific embodiments:

[0036] 1) Time-Sensitive Networking (TSN): TSN is a network that ensures that data transmission on Ethernet is predictable, reliable, and has strict time constraints.

[0037] 2) Kubernetes (k8s for short): is an open source platform for automating the deployment, scaling, and management of containerized applications.

[0038] 3) Data Distribution Service (DDS): This service is used to transmit data from a single source to multiple destinations. It is commonly used in scenarios such as broadcast messaging, publish-subscribe systems, and data synchronization. The main functions of a data distribution service include receiving data, managing the distribution and transmission of data, and transmitting data to multiple recipients.

[0039] The communication solution based on the time-sensitive network provided in the embodiment of the present application is mainly used for communication between containers, such as communication between containers in kubernetes, or communication between containers in Docker Swarm, or communication between containers in Apache Mesos, or communication between containers in HashiCorp Nomad, etc. Specifically: based on the time-sensitive network, the containers located at different nodes are connected using a data distribution service. Since the time-sensitive network is a deterministic network, the time-sensitive network (low-level network, such as layer 1 and layer 2) is connected to the high-level (such as layer 3-6) service through the data distribution service, thereby ensuring the determinism of network communication. The quality of network communication is guaranteed.

[0040] The following is a detailed introduction to a communication architecture based on a time-sensitive network provided by the first embodiment of this application. The communication architecture of this embodiment is described by taking the establishment based on kubernetes as an example. Figure 1 The figure shows a schematic diagram of the structure of a communication architecture 10 based on a time-sensitive network. The communication architecture 10 includes: a message publishing node 100, a message subscription node 200 and a data distribution service 300. The data distribution service 300 includes a first data distribution node (DDS node-1) and a second data distribution node (DDS node-2). It should be understood that this embodiment is described by taking the communication architecture as an example including a message publishing node and a message subscription node. In other embodiments, the communication architecture may include multiple message publishing nodes and multiple message subscription nodes according to the actual topology structure. These nodes communicate with each other through a time-sensitive network. When multiple nodes are included, a corresponding DDS node is deployed on each node, and these DDS nodes constitute the data distribution service 300.

[0041] Next, we will introduce each node in detail.

[0042] Message publishing node 100 includes a first container Container-1 and a second container Container-2. The first container Container-1 is used to host an application Application-1, which is integrated with a data forwarding service AgentClient-1. The second container Container-2 is used to host a data forwarding listening service DDSAgent-1 and a DDS node-1 (i.e., a first data distribution node). The data forwarding listening service DDSAgent-1 is communicatively connected to the DDS node-1 (i.e., the data forwarding listening service DDSAgent-1 is connected to the data distribution service 300). In message publishing node 100, the data forwarding service AgentClient-1 in the first container Container-1 and the data forwarding listening service DDSAgent-1 in the second container Container-2 are communicatively connected, thereby enabling communication between the first container Container-1 and the second container Container-2. Specifically, when the data forwarding service AgentClient-1 in the first container Container-1 writes data to the shared memory located in the message publishing node 100 (referred to as the first shared memory in the following description of this application), the data forwarding monitoring service DDSAgent-1 in the second container Container-2 detects that the data in the first shared memory has changed, and takes out the data and writes it to the locally deployed DDS node-1, thereby completing the data transfer from the message publishing node 100 to the data distribution service.

[0043] It should be understood that the application Application-1 in the first container Container-1 has a data writing function DataWriter.

[0044] It should be understood that the data forwarding service AgentClient-1 in the first container Container-1 and the data forwarding monitoring service DDSAgent-1 in the second container Container-2 are both pre-defined services, and the data forwarding monitoring service DDSAgent-1 in the second container Container-2 is deployed in the second container Container-2 as a daemon process.

[0045] It should be understood that the data distribution service 300 is also pre-defined in Kubernetes.

[0046] The message subscription node 200 includes a third container Container-3 and a fourth container Container-4. The third container Container-3 is similar to the first container Container-1 and is also used to carry the application Application-2. The application Application-2 is integrated with the data forwarding service AgentClient-2. The fourth container Container-4 is similar to the second container Container-2 and is also used to carry the data forwarding monitoring service DDSAgent-2 and DDS node-2 (i.e., the second data distribution node). The data forwarding monitoring service DDSAgent-2 is communicatively connected to the DDS node-2 (i.e., the data forwarding monitoring service DDSAgent-2 is connected to the data distribution service 300). In the message subscription node 200, the data forwarding service AgentClient-2 in the third container Container-3 and the data forwarding monitoring service DDSAgent-2 in the fourth container Container-4 are communicatively connected, thereby realizing communication between the third container Container-3 and the fourth container Container-4. Specifically, when the data forwarding monitoring service DDSAgent-2 in the fourth container Container-4 monitors a change in the subscription message, the changed subscription message is forwarded to the shared memory (referred to as the second shared memory in the following description of this application) located in the message subscription node 200 through the data forwarding service AgentClient-2 in the third container Container-3, and the subscription message is read out through the data forwarding service AgentClient-2 in the third container Container-3, thereby completing the distribution of data from the data distribution service to the message subscription node 200.

[0047] It should be understood that the application Application-1 in the first container Container-1 has a data reading function DataReader.

[0048] It should be understood that the data forwarding service AgentClient-2 in the third container Container-3 and the data forwarding monitoring service DDSAgent-2 in the fourth container Container-4 are both pre-defined services, and the data forwarding monitoring service DDSAgent-2 in the fourth container Container-4 is deployed in the fourth container Container-4 as a daemon process.

[0049] In this embodiment, the first data distribution node DDS Node-1 and the second data distribution node DDS Node-2 are connected via a time-sensitive network communication, thereby realizing communication between the message publishing node and the message subscription node.

[0050] Then, a connection method between the message publishing node 100 and the message subscription node 200 is introduced in detail.

[0051] The second container, Container-2, of message publishing node 100 includes network interface eth0, which is connected to a virtual switch, Virtual Switch. This virtual switch is also connected to the external connection interface NIC of message publishing node 100, and can also communicate with other nodes through this external connection interface NIC. Similarly, the fourth container, Container-4, of message subscription node 200 includes network interface eth0, which is connected to a virtual switch, Virtual Switch. This virtual switch is also connected to the external connection interface NIC of message subscription node 200, and can also communicate with other nodes through this external connection interface NIC of message subscription node 200. In this embodiment, the external connection interface NIC of message publishing node 100 and the external connection interface NIC of message subscription node 200 are connected via a physical switch, Switch, thereby enabling communication between message publishing node 100 and message subscription node 200. It should be understood that the virtual switch Virtual Switch located at each node and the physical switch Switch located between the two nodes are both selectively connectable devices.

[0052] The communication architecture provided in this embodiment combines the time-sensitive network technology of the lower layers (Layer 1 (physical layer) and Layer 2 (data link layer)) with the network of higher layers (Layer 3 (network layer), Layer 4 (transport layer), Layer 5 (session layer), and Layer 6 (presentation layer)) through the data distribution service 300, so that the time-sensitive network can give full play to its deterministic transmission advantages, and then directly apply deterministic transmission to applications, thereby ensuring the network quality of real-time transmission.

[0053] The second embodiment of the present application provides a communication method, which is applied to the communication architecture 10 of the first embodiment. In the second embodiment, the communication method is introduced by taking the application program as a brake service as an example. Figure 1 and Figure 2 The communication method provided in this embodiment is introduced in detail.

[0054] A. Initialization step: initializing the data distribution service in the communication architecture and initializing the subscription information of the message subscription nodes in the communication architecture.

[0055] First, we will introduce the initialization of the data distribution service in the communication architecture:

[0056] In this embodiment, the data distribution service 300 must first be initialized. Specifically, the data distribution service structure is adjusted based on changes in the data distribution service's network information. Network information changes may include, but are not limited to, bandwidth changes, node failures, distribution strategy adjustments, load changes, etc. Adjustments to the data distribution service structure include, but are not limited to, adjustments to quality of service, load balancing strategies, redundancy and fault tolerance mechanisms, and security measures.

[0057] In this embodiment, a custom resource definition controller (DdsModify-CRD-Controller) for controlling data distribution service resources can be predefined in Kubernetes. This controller is used to issue instructions for adjusting the data distribution service system structure based on changes in the data distribution service's network information. In this embodiment, a custom resource definition operator (DdsModify-CRD-Operator) for operating data distribution service resources is also predefined in Kubernetes. This operator is used to adjust the data distribution service system structure based on instructions issued by the DdsModify-CRD-Controller.

[0058] Through the synergy of DdsModify-CRD-Controller and DdsModify-CRD-Operator, the data distribution service in the communication architecture can be initialized.

[0059] Next, we will introduce how to initialize the subscription information of the message subscription node in the communication architecture:

[0060] like Figure 2 The initialization process shown here represents the process of initializing the subscription information of a message subscription node. Specifically, the data forwarding service AgentClient-2 in the message subscription node first initializes a process to monitor changes in the second shared memory data. It then communicates with the data forwarding listening service DDSAgent-2 in the message subscription node via HTTP(S). DDSAgent-2 then initializes the subscription information to the data distribution service 300, completing the initialization of the subscription information for the message subscription node.

[0061] B. Work steps. This work step includes the work steps on the message publishing node and the work steps on the message subscription node. B-1 to B-2 are the work steps on the message publishing node, B-4 to B-5 are the work steps on the message subscription node, and B-3 is the process of data distribution service pushing messages. Figure 2 The whole process of the working steps is described in detail by the working stages in the text.

[0062] B-1. An application in a first container deployed on a message publishing node receives first data and writes the first data into a first shared memory through a data forwarding service in the first container. The first shared memory is located on the message publishing node.

[0063] In this step, the first data is a video stream acquired by a video capture device, and the operation instructions are obtained by processing the video stream. Specifically, after receiving the video stream data, Application-1, deployed in the first container of the message publishing node, analyzes and processes it. The data forwarding service AgentClient-1 in the first container then writes the analyzed and processed operation instructions to the first shared memory. For example, in a braking application, the operation instruction is a braking command if the captured video stream data is analyzed and processed to determine that a braking operation should be executed.

[0064] B-2. When the data forwarding monitoring service in the second container deployed in the message publishing node monitors that the first shared memory writes the first data, the data forwarding monitoring service in the second container forwards the first data to the data distribution service.

[0065] In this step, after the data forwarding monitoring service DDSAgent-1 monitors the operation instruction, the data forwarding monitoring service DDSAgent-1 forwards the operation instruction to the data distribution service 300 by asynchronously writing data.

[0066] B-3. ​​The data distribution service pushes the first data to the message subscription node.

[0067] In this step, the distribution service 300 pushes the video stream data to the message subscription node.

[0068] B-4. After the data forwarding monitoring service deployed on the message subscription node monitors the push, the data forwarding monitoring service deployed in the fourth container forwards the first data to the second shared memory, where the second shared memory is located on the message subscription node.

[0069] In this step, after the data forwarding monitoring service DDSAgent-2 of the message subscription node monitors the pushed operation instruction, the data forwarding monitoring service DDSAgent-2 forwards the operation instruction to the second shared memory.

[0070] B-5. The data forwarding service deployed in the third container of the message subscription node reads the first data located in the second shared memory.

[0071] In this step, the data forwarding service AgentClient-2 reads the operation instruction data and performs corresponding operations based on the operation instruction as required.

[0072] Thus, the transmission of the data stream in the communication architecture is completed.

[0073] It should be understood that the above-mentioned message publishing node and message subscription node operate independently, that is, when the message subscription node is not working, the message publishing node can work alone; similarly, when the message publishing node is not working, the message subscription node can also work alone.

[0074] Among them, the specific implementation methods of each functional module of the communication architecture in this embodiment can be found in the introduction of the above-mentioned first embodiment, and will not be repeated in this embodiment.

[0080] The memory 920 may include a read-only memory and a random access memory, and provides instructions and data to the processor 910. A portion of the processor 910 may also include a non-volatile random access memory. For example, the processor 910 may also store information about the device type.

[0081] When the computing device 900 is running, the processor 910 executes the computer-executable instructions in the memory 920 to perform any operation step of the above method and any optional embodiment thereof.
