[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0043] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.
[0044] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.
[0045] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.
[0046] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0047] In the description of the present application, unless otherwise specified, “plurality” means two or more.
[0048] With the development of intelligent manufacturing technology, the intelligence in the field of production and manufacturing is becoming more and more popular. At present, the fifth generation mobile communication technology (5G) and other new generation mobile communication technologies are used to realize the communication between industrial controllers (such as programmable logic controller (PLC)) and industrial field input / output (I / O) devices (referred to as "controller-device (C2D)" communication).
[0049] Specifically, the PLC works in a cyclic scanning mode, and in each scanning cycle, the PLC needs to send the output data to the I / O device. In the current 5G-based cloud PLC industrial control system, the I / O data transmission scheme is: the PLC encapsulates the output I / O data into multiple Internet protocol (IP) data packets and sends them to each I / O device through the 5G network. However, during the operation of the PLC, the above operations need to be repeated continuously, resulting in the 5G network needing to carry a large number of IP data packets that encapsulate I / O data.
[0050] In the related art, for PLC control services, data is usually sent repeatedly at a certain time interval, with a fixed periodicity in time. For example, in the industrial field, vehicle network, and airborne network where time-sensitive networking (TSN) is currently applied, key services are known and rarely change suddenly. Therefore, the traffic characteristics of service data are known, so when configuring resources for service data, a network static configuration solution is usually used for configuration.
[0051] However, there are also businesses in TSN that have high requirements for real-time communication. When dealing with such businesses, static network configuration will not be able to perform adaptive configuration, which may cause network congestion and data loss during data transmission.
[0052] In view of this, the embodiment of the present application provides a resource configuration method that can be applied to the TSN resource configuration scenario. Among them, the method screens the message data group that is not configured with transmission delay and transmission bandwidth to accurately identify the valid message data according to the data category of each message data, so as to avoid resource configuration for all message data, reducing the probability of network congestion; at the same time, for valid message data of different data categories, according to its transmission interval and specific transmission requirements (such as delay requirements, bandwidth requirements, transmission priority) to reasonably configure the target network resources, which helps to optimize the distribution of network traffic, further reduce the network congestion caused by improper resource allocation, and sequential transmission based on transmission priority can reduce the risk of data loss.
[0053] The implementation of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.
[0054] Figure 1 This is a schematic diagram of the architecture of a resource configuration system provided in an embodiment of the present application. Figure 1 As shown, the resource configuration system 100 includes: a resource configuration device 110 and a data server 120 .
[0055] The resource configuration device 110 and the data server 120 may be one or more. For ease of understanding, Figure 1 Only one resource configuration device and one data server are shown.
[0056] The resource configuration device 110 and the data server 120 are connected via a communication link. The communication link may be a wired communication link or a wireless communication link, which is not limited in the present application.
[0057] In some embodiments, the resource configuration device 110 can obtain a message data group for which transmission delay and transmission bandwidth are not configured, and then determine valid message data from the message data group for which network resources are not configured based on a category database, and finally, for each data category, configure target network resources for the valid message data based on the transmission interval of the valid message data under the data category, and the transmission requirements of the valid message data (such as delay requirements, bandwidth requirements, and transmission priority).
[0058] In some embodiments, the data server 120 is used for data categories of all message data in the category database, and provides the resource configuration device 110 with the category database for screening valid message data.
[0059] The following takes the resource configuration device 110 as a TSN switch as an example. Figure 2 The structure of the resource allocation device 110 will be described.
[0060] like Figure 2 , which is a schematic diagram of the structure of a TSN switch provided by an embodiment of the present application. The TSN switch 200 may include a traffic parameter collection module 210, a traffic matching and data preprocessing module 220, a periodic calculation module 230, and a network scheduling module 240. The traffic parameter collection module 210, the traffic matching and data preprocessing module 220, the periodic calculation module 230, and the network scheduling module 240 are connected in sequence.
[0061] The traffic parameter collection module 210 is used to implement the functions of receiving message data, collecting parameters, and transmitting parameters for periodically arriving message data.
[0062] The traffic matching and data preprocessing module 220 is used to implement the functions of traffic identification, data sampling processing, and data preprocessing on the message data transmitted by the traffic parameter collection module 210 .
[0063] The periodic calculation module 230 is used to implement the function of periodic calculation and data transmission of the message data processed by the traffic matching and data preprocessing module 220 .
[0064] The network scheduling module 240 is used to arrange network resources for the message data transmitted by the periodic calculation module 230 and issue network resource configuration.
[0065] In this way, through the collaboration between multiple modules, adaptive configuration of network resources is achieved, and the performance requirements for network equipment are reduced, avoiding network congestion and data loss.
[0066] When implemented by hardware, each module in the resource configuration device 110 can be integrated into Figure 3 The hardware structure of the electronic device shown is implemented. Specifically, Figure 3 As shown, the basic hardware structure of electronic equipment is introduced.
[0067] Figure 3 The hardware structure diagram of an electronic device provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the electronic device includes at least one processor 301, a communication line 302, and at least one communication interface 304, and may also include a memory 303. The processor 301, the memory 303 and the communication interface 304 may be connected via the communication line 302.
[0068] The processor 301 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application, such as one or more digital signal processors (DSP), or one or more field programmable gate arrays (FPGA).
[0069] The communication link 302 may include a pathway for transmitting information between the above-mentioned components.
[0070] The communication interface 304 is used to communicate with other devices or communication networks, and can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.
[0071] The memory 303 may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, an optical disc storage (including a compressed optical disc, a laser disc, an optical disc, a digital versatile disc, a Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to include or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited to these.
[0072] In one possible design, the memory 303 can exist independently of the processor 301, that is, the memory 303 can be a memory outside the processor 301. In this case, the memory 303 can be connected to the processor 301 through the communication line 302, and is used to store execution instructions or application code, and the processor 301 controls the execution to implement the resource configuration method provided in the following embodiment of the present application. In another possible design, the memory 303 can also be integrated with the processor 301, that is, the memory 303 can be the internal memory of the processor 301, for example, the memory 303 is a high-speed cache, which can be used to temporarily store some data and instruction information.
[0073] As a possible implementation, the processor 301 may include one or more CPUs, for example Figure 3 As another possible implementation, the electronic device may include multiple processors, such as Figure 3 As another possible implementation, the electronic device may further include an output device 305 and an input device 306.
[0074] It should be pointed out that the various embodiments of the present application can learn from or refer to each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can all refer to each other without limitation.
[0075] Figure 4 A flowchart of a resource configuration method provided in an embodiment of the present application, the subject executing the method may be as follows Figure 1 The resource allocation device 110 shown in FIG. Figure 2The TSN switch 200 shown may also be various units / modules in the resource configuration device 110 or the TSN switch 200, such as an integrated circuit or a chip, which is not specifically limited in the embodiment of the present application.
[0076] For example, Figure 4 As shown, the resource configuration method provided in the embodiment of the present application includes the following steps:
[0077] S401: Acquire a message data group for which no network resources are configured.
[0078] Among them, network resources include transmission delay and transmission bandwidth.
[0079] In some embodiments, different data processing nodes and data transmission paths support different transmission delays and transmission bandwidths. The data processing node can be a cloud node or an edge computing node; the data transmission path refers to the communication link between cloud nodes, or between a cloud node and an edge computing node, or between edge computing nodes.
[0080] In other words, the data processing nodes and data transmission paths refer to the forwarding nodes, computing nodes, and communication links between nodes from the initial sending node to the final receiving node of the message data.
[0081] Optionally, the above-mentioned acquisition of the message data group for unconfigured network resources may first receive initial message data, then parse the transceiver information of the initial message data, and determine all message data for unconfigured network resources in the initial message data according to the transceiver information.
[0082] The information of the transmitting and receiving end may include information such as IP address, media access control (MAC) address, port number, etc. The IP address includes the IP address of the source device and the IP address of the destination device of the initial message data; the port number includes the port number of the source device and the port number of the destination device of the initial message data.
[0083] In an optional implementation, the initial message data in the initial message data that does not match the known transmitting and receiving end information can be determined as a message data group for which network resources are not configured.
[0084] In the embodiment of the present application, the above-mentioned known transceiver information is obtained through known message data previously sent by a network control center (such as a centralized network configuration (CNC)). The known message data is message data of the network resources that have been configured.
[0085] In some embodiments, the IP address, MAC address, port number and other information of each initial message data can be compared with the IP address, MAC address, port number and other information of the known message data sent by the CNC, and all initial message data that are inconsistent with the comparison can be determined as a message data group for which network resources are not configured.
[0086] Furthermore, a timestamp may be added to the message data for which no network resources are configured, and the timestamp is the start sending time point of the message data.
[0087] In another optional implementation, the initial message data in the initial message data that matches the known transceiver information can be determined as the message data group for which the network resources have been configured.
[0088] In some embodiments, the IP address, MAC address, port number and other information of each initial message data can be compared with the IP address, MAC address, port number and other information of the known message data sent by the CNC, and all initial message data that are consistent with the comparison can be determined as a message data group for the configured network resources.
[0089] Furthermore, for the message data group for which the network resources have been configured, the network resources may be configured according to a preset configuration policy, and a target tag may be set.
[0090] The target tag is used to instruct to stop resource configuration for the message data group for which network resources have been configured.
[0091] In the embodiment of the present application, the preset configuration policy may be a default configuration policy issued by the CNC.
[0092] In some embodiments, if it is determined that the message data has been configured with network resources, the new network resource configuration for the message data is stopped, and data transmission is performed according to the network resources that have been configured for the message data itself.
[0093] In this way, by screening out a portion of message data for which network resources have been configured and only performing subsequent processing on message data for which network resources have not been configured, the load of the resource configuration device can be reduced, and the resource configuration efficiency can be indirectly improved.
[0094] S402: Determine valid message data from a message data group of unconfigured network resources based on a category database.
[0095] The category database may be a pre-set database, which may include data categories of multiple message data.
[0096] Optionally, the message data group for which the network resources are not configured may be parsed first to obtain the data category of each message data for which the network resources are not configured.
[0097] In some embodiments, the message data of all unconfigured network resources can be parsed through an N deep packet inspection (NDPI) library to extract traffic characteristics, and the traffic characteristics are matched with a preset template file to obtain the data category of the message data of each unconfigured network resource.
[0098] Exemplarily, the NDPI library can be used to extract traffic features from each message data that has no network resources configured to obtain the IP address, MAC address, port number, protocol type, etc. of the message data, and then match the IP address, MAC address, port number, protocol type, etc. with the preset template file to determine the data category of each message data.
[0099] Further optionally, after determining the data category of each message data of the unconfigured network resource, it is also possible to determine whether the message data of the unconfigured network resource is valid message data according to the data category of each message data of the unconfigured network resource and the category database.
[0100] In an optional implementation, the message data in the message data group for which no network resources are configured and which matches the data category in the category database may be determined as valid message data.
[0101] In some embodiments, the IP address, MAC address, port number and other information of each message data that has not been configured with network resources can be compared with the IP address, MAC address, port number and other information of the message data in the category database, and the message data that matches the comparison can be determined as valid message data.
[0102] In another optional implementation, the message data in the message data group for which no network resources are configured and which does not match the data category in the category database may be determined as invalid message data.
[0103] In some embodiments, the IP address, MAC address, port number and other information of each message data that has not been configured with network resources can be compared with the IP address, MAC address, port number and other information of the message data in the category database, and the message data that is inconsistent with the comparison can be determined as invalid message data.
[0104] Furthermore, the determined invalid message data may be eliminated.
[0105] In this way, invalid message data is screened and eliminated through the category database, which further reduces the data that the resource configuration device needs to process, reduces the load, and improves the performance of the resource configuration device.
[0106] S403: For each data category, according to the transmission interval of the valid message data under the data category and the transmission requirement of the valid message data, configure target network resources for the valid message data.
[0107] Among them, transmission requirements include latency requirements, bandwidth requirements, and transmission priority.
[0108] As described in S402 above, the protocol type of the message data and the data category of the message data may be obtained through the NDPI library analysis.
[0109] In some embodiments, priority may also be assigned to the message data according to the protocol type of each message data to obtain the transmission priority of each message data for which network resources are not configured.
[0110] In other embodiments, the transmission bandwidth and transmission delay required for each message data may also be identified according to the data category of each message data.
[0111] In this way, by accurately identifying the transmission priority, bandwidth requirements, and latency requirements of different message data, it is ensured that when network resources are subsequently configured, the configured network resources can meet the transmission requirements of the message data, thereby ensuring successful message data transmission.
[0112] In some embodiments, the transmission interval of valid message data refers to the periodic time interval between two adjacent valid message data, that is, after a valid message data is sent, the next valid message data is sent after the time interval.
[0113] In some embodiments, the window duration for sending message data can be configured according to the interval duration of valid message data, and the transmission order of valid message data can be configured according to the transmission priority of the valid message data. Further, according to the delay requirements and bandwidth requirements of the valid message data, data processing nodes and data transmission paths that can support the delay requirements and bandwidth requirements can be configured to provide transmission delay and transmission bandwidth for transmitting the valid message data.
[0114] For example, take three valid message data (A, B, C) under the same data category with a transmission interval of 5 milliseconds, a delay requirement of 0.5 milliseconds, a bandwidth requirement of 1 Gbps, a transmission priority of 3 for A, a transmission priority of 5 for B, and a transmission priority of 1 for C. B, A, and C can be sent in order of transmission priority from high to low, with an interval of 5 milliseconds, and the transmission delay of the network is set to be less than or equal to 0.5 milliseconds, and the transmission bandwidth of the network is set to be greater than or equal to 1 Gbps.
[0115] In the resource configuration method provided in the embodiment of the present application, by screening the message data groups that are not configured with transmission delay and transmission bandwidth, the valid message data therein can be accurately identified according to the data category of each message data, so as to avoid resource configuration for all message data, thereby reducing the probability of network congestion; at the same time, for valid message data of different data categories, the target network resources are reasonably configured according to their transmission intervals and specific transmission requirements (such as delay requirements, bandwidth requirements, and transmission priority), which helps to optimize the distribution of network traffic and further reduce network congestion caused by improper resource allocation. In addition, sequential transmission based on transmission priority can reduce the risk of data loss.
[0116] As described in S403, in some embodiments, the transmission interval of valid message data refers to the periodic transmission time interval between two adjacent valid message data. Figure 5 Describe in detail the transmission interval for determining valid message data.
[0117] For example, Figure 5 As shown, the transmission interval of valid message data can be determined by the following steps:
[0118] S501. According to the data category of each valid message data, all valid message data are divided into valid message data corresponding to each of the multiple data categories.
[0119] In the embodiment of the present application, since the transmission intervals of message data of different data categories are different, it is necessary to classify the message data to obtain message data under different data categories.
[0120] Exemplarily, valid message data with the same IP address, MAC address, port number, and protocol type can be divided into valid message data under the same data category according to the IP address, MAC address, port number, and protocol type of each valid message data.
[0121] S502: Obtain the timestamp of each valid message data under the same data category from the time database.
[0122] The time database includes the timestamp of each message data in the message data group for which no network resources are configured.
[0123] Optionally, the timestamp of the message data for which no network resources are configured in S401 may be stored in the time database in advance.
[0124] In some embodiments, consistent message data may be screened out from a time database according to the data category of each valid message data, and then the timestamp of the message data may be read as the timestamp of each valid message data.
[0125] S503: For each data category, determine the transmission interval of the valid message data under the data category according to the timestamp of each valid message data under the data category.
[0126] In an optional implementation, the time difference between two adjacent start sending time points of valid message data can be directly calculated based on the start sending time point of each valid message data, and the time difference can be used as the transmission interval of the valid message data.
[0127] In another optional implementation method, the time interval between each two adjacent valid message data can be determined based on the timestamp of each valid message data under the data category, and then the average time interval of the valid message data can be determined based on the time interval between each two adjacent valid message data, and the average time interval can be used as the transmission interval of the valid message data.
[0128] In some embodiments, before determining the average time interval, it is also necessary to delete and fill the valid message data with abnormal time intervals in the time intervals between all two adjacent valid message data to obtain processed valid message data.
[0129] Exemplarily, the valid message data under each data category screened out in the time database can be combined into set A, and then the time interval between each two adjacent valid message data is calculated, and the valid message data with abnormal time intervals (such as the time interval is greater than or less than the interval range) is deleted, and the missing valid message data is filled in to obtain set B (i.e., the processed valid message data).
[0130] Furthermore, the time intervals between all two adjacent valid message data in the processed valid message data are averaged to obtain an average time interval.
[0131] In this way, by deleting erroneous data and filling in missing data, the continuity and rationality of the data are ensured, thereby indirectly improving the accuracy of the subsequent determination of the transmission interval of valid message data.
[0132] Optionally, after the average time interval is determined, the transmission interval of the valid message data may be determined according to the average time interval.
[0133] In an optional implementation, the average time interval may be directly determined as the transmission interval of valid message data.
[0134] In another optional implementation, when the difference between the time interval between all two adjacent valid message data and the average time interval is less than or equal to a preset difference, the average time interval may be determined as the transmission interval of the valid message data.
[0135] In one example, the preset difference value may be determined according to the allowed delay and allowed jitter, wherein the allowed delay and allowed jitter may be set according to the data category of the valid message data, and different data categories correspond to different allowed delays and allowed jitters.
[0136] In another example, the preset difference value may be a manually set value, which may be flexibly adjusted according to actual scenarios. For example, the preset difference value may be 1 millisecond.
[0137] For example, the preset difference is 1 millisecond, and the number of valid message data is 6 (A, B, C, D, E, F). If the time interval between A and B is 5 milliseconds, the time interval between B and C is 5.3 milliseconds, the time interval between C and D is 5.8 milliseconds, the time interval between D and E is 4.7 milliseconds, and the time interval between E and F is 4.2 milliseconds, the average time interval is 5 milliseconds, and the 5 time differences are 0 milliseconds, 0.3 milliseconds, 0.8 milliseconds, 0.3 milliseconds, and 0.8 milliseconds, respectively, indicating that the 6 valid message data are periodic, that is, the average time interval of 5 milliseconds can be used as the transmission interval of the valid message data.
[0138] In this way, the final transmission interval is determined only after ensuring that the time interval of all valid message data is within the allowable error range, which further ensures the accuracy of the determined transmission interval.
[0139] The following combination Figure 2 , refer to Figure 6 , the complete process of the resource configuration method provided in the embodiment of the present application is exemplified.
[0140] For example, Figure 6 As shown, the complete process of the resource configuration method provided in the embodiment of the present application may include the following steps:
[0141] S601 , the traffic parameter collection module 210 receives initial message data, collects parameters for the initial message data, and sends the collected message data to the traffic matching and data preprocessing module 220 .
[0142] In some embodiments, receiving the initial message data includes: after receiving the initial message data, judging the message data of configured network resources and the message data of unconfigured network resources in the initial message data according to the rules issued by the CNC and based on information such as IP address, MAC address, port number, etc.
[0143] Furthermore, an access control list (ACL) rule is issued to the message data of the configured network resources, and resource configuration for the message data of the configured network resources is stopped.
[0144] In some embodiments, collecting parameters of initial message data includes: timestamping message data that is not configured with network resources, identifying specific message features (such as MAC address) through ACL, performing corresponding operations (such as allowing passage), and reading key data such as virtual local area network (VLAN), MAC address, port number, etc.
[0145] In some embodiments, after the above-mentioned key data is collected, the collected key data can be encapsulated into a message format (Ethernet type) and sent to the traffic matching and data preprocessing module 220 through a specific protocol (such as OpenFlow protocol).
[0146] S602, the traffic matching and data preprocessing module 220 performs traffic identification, data sampling and data preprocessing on the message data for which network resources are not configured.
[0147] In some embodiments, Figure 7 As shown, traffic identification includes:
[0148] S701. Call the NDPI library to extract traffic features.
[0149] Exemplarily, the NDPI library may be used to parse the message data and extract traffic features.
[0150] S702: Match template files and identify data categories.
[0151] Exemplarily, the traffic characteristics may be matched with a preset template file to complete the classification of data categories.
[0152] S702: Data category storage.
[0153] Exemplarily, data categories may be stored in a category database, and parameters such as jitter and delay may be preset.
[0154] In some embodiments, data sampling processing means that since message data has periodic characteristics, a sampling technique can be used to select part of the message data for monitoring based on information such as message data size and IP address.
[0155] In this way, based on the periodicity of message data, part of the message data is selected as representative data for processing, which can alleviate the data processing pressure of the TSN switch and improve performance.
[0156] In some embodiments, data preprocessing refers to matching the selected message data with the data categories recorded in the category database, treating the successfully matched message data as valid message data and saving it in the database; treating the unsuccessfully matched message data as invalid message data and eliminating it.
[0157] S603: The periodic calculation module 230 performs periodic calculation and data transmission on the valid message data.
[0158] In some embodiments, periodic calculations include data grouping, data cleaning, calculating time intervals, and checking periodic operations.
[0159] Data grouping refers to grouping valid message data according to parameters such as IP address, MAC address, port number, etc., and querying the timestamp corresponding to each group of valid message data from the time database and putting them into set A.
[0160] Data cleaning refers to calculating the time interval between two adjacent valid message data in set A, deleting valid message data with incorrect time interval, and supplementing the missing valid message data to generate a new set B.
[0161] Calculating the time interval refers to calculating the time interval between each valid message data in the calculation set B.
[0162] Checking the periodicity means taking the average value of the calculated time interval as a benchmark, and comparing the time interval between each valid message data with the average value. If the difference between the time interval and the average value is within the allowable range of the delay and jitter set in S602, it is determined that the valid message data has periodicity; otherwise, it is determined that the valid message data has no periodicity.
[0163] Further, when it is determined that the valid message data has periodicity, the average value is used as the transmission interval of the valid message data.
[0164] In some embodiments, data transmission refers to sending the acquired period (transmission interval of valid message data), bandwidth requirements of valid message data, VLAN, transmission priority, byte size, delay requirements and other data to the network scheduling module 240 through a specific interface (such as representational state transfer application programming interface (Restful API)).
[0165] S604: The network scheduling module 240 arranges network resources for the valid message data and issues network resource configuration.
[0166] In some embodiments, network resource scheduling refers to receiving data sent by the periodic calculation module 230 and scheduling network resources using a scheduling algorithm according to the data content.
[0167] In some embodiments, sending down the network resource configuration means sending the orchestrated network resource configuration to the switch through a southbound interface (such as OpenFlow), so that the switch schedules and optimizes the traffic according to the received network resource configuration.
[0168] The following is an exemplary description of the interaction process of the resource configuration method provided in the embodiment of the present application.
[0169] For example, in combination Figure 2 and Figure 6 ,like Figure 8 As shown, the interaction process of the resource configuration method may include:
[0170] S801. The traffic parameter collection module receives message data and collects parameters.
[0171] S802: The traffic parameter collection module transmits the message data to the traffic matching and data preprocessing module.
[0172] S803. The traffic matching and data preprocessing module records the data type of the message data and presets the delay and jitter.
[0173] S804: The traffic matching and data preprocessing module performs data sampling and data preprocessing to obtain valid message data.
[0174] S805. The traffic matching and data preprocessing module sends the valid message data to the periodic calculation module.
[0175] S806. The periodic calculation module performs periodic calculation on the valid message data to obtain a transmission interval of the valid message data.
[0176] S807. The periodic calculation module sends data such as transmission interval, bandwidth requirement, VLAN, transmission priority, byte size, and delay requirement to the network scheduling module.
[0177] S808. The network scheduling module arranges network resources for the valid message data to obtain network resource configuration.
[0178] S809. The network scheduling module sends the network resource configuration to the TSN device.
