Description

Technical Field

[0001] The present application relates to the field of optical network communication technology, and in particular to a message transmission method, device, computer equipment and storage medium. Background Art

[0002] Industrial PON (Passive Optical Network) systems have the advantages of high bandwidth, long-distance transmission, and anti-electromagnetic interference. They support single-fiber point-to-multipoint applications. In addition to carrying industrial automation and intelligent manufacturing applications, they can also simultaneously transmit converged business applications such as the Internet, voice, and video to meet the diverse business needs of factory users. When existing industrial PON systems carry converged services, they usually follow the security configuration mode under the Internet and set a fixed lower broadcast / multicast suppression threshold parameter on the OLT (optical line terminal) device to limit broadcast / multicast network message attacks or unnecessary access messages.

[0003] EtherCAT is a real-time Ethernet communication protocol commonly used in the field of industrial automation. Some EtherCAT type messages have the characteristics of periodic communication. Such EtherCAT type messages are relatively high-frequency small packets, which are mainly used for process data transmission such as industrial equipment control and EtherCAT master-slave equipment synchronization. They have high real-time requirements and are highly sensitive to link delay and packet loss.

[0004] When industrial PON sets a fixed suppression threshold parameter with a low parameter value, packet loss will be performed when the threshold is exceeded. Although network security is guaranteed, when carrying EtherCAT type messages, high-frequency EtherCAT type messages will be lost, seriously affecting message transmission. Summary of the invention

[0054] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0055] The message transmission method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the OLT device receives the message to be transmitted sent by the EtherCAT master station or the Internet server. The OLT device obtains the message type of the message to be transmitted. When the message type is a target type (for example, an EtherCAT type), the message characteristics of the message to be transmitted are obtained. The OLT device determines the target suppression threshold parameter of the OLT device based on the message characteristics of the message to be transmitted. Based on the target suppression threshold parameter, the OLT device transmits the message to be transmitted, that is, transmits the message to be transmitted to the EtherCAT slave station or industrial terminal through the ONU device.

[0056] Among them, OLT (optical line terminal) is the terminal equipment that users use to connect to the optical fiber trunk line.

[0057] ONU (Optical Network Unit) equipment refers to the user-side equipment in the optical fiber communication network. ONU equipment works in conjunction with OLT equipment. OLT equipment is located at the center of the industrial PON network and is responsible for sending the messages to be transmitted to the ONU equipment.

[0058] EtherCAT is a real-time Ethernet communication protocol that combines standard Ethernet technology with real-time control requirements and is widely used in the field of industrial automation. It adopts a master-slave architecture, where the master station is responsible for sending and receiving data, and the slave station performs specific control tasks. Data is transmitted cyclically between the master station and the slave station, and high-speed data exchange is achieved through an efficient frame structure and processing mechanism.

[0059] In one embodiment, Figure 2 is a flow chart of a message transmission method provided according to an embodiment of the present application, in which the method is applied to Figure 1 Taking the OLT device in the example as an example, the method includes the following steps:

[0060] S201: Obtain the message type of the message to be transmitted.

[0061] Among them, the message to be transmitted refers to the message that needs to be broadcast or multicast. In this application, the message to be transmitted can refer to the message that is continuously transmitted, not to a specific message.

[0062] As an optional implementation of the embodiment of the present application, a source device that generates the message to be transmitted is obtained, and a message type of the message to be transmitted is determined according to a device type of the source device.

[0063] Another optional implementation of the embodiment of the present application is to parse the message to be transmitted to obtain the message header of the message to be transmitted, and determine the message type of the message to be transmitted according to the field content in the message header. Specifically, the message type of the message to be transmitted is determined according to the frame type in the message header of the message to be transmitted (as shown in Table 1).

[0064] Table 1

[0065]

[0066] S202: When the message type is a target type, obtain a message feature of the message to be transmitted.

[0067] The target type refers to a pre-specified type. It should be noted that the target type of the present application mainly refers to the EtherCAT type, but is not limited to the EtherCAT type. The present application does not limit the specific type of the target type. The message feature refers to the relevant features of the message to be transmitted.

[0068] Exemplarily, as shown in Table 1 above, if the frame type in the message header (as shown in Table 1) of the message to be transmitted is "0x88A4", it indicates that the message type of the message to be transmitted is an EtherCAT type.

[0069] Optionally, the message characteristics in the present application include but are not limited to at least one of message data payload, transmission frequency and transmission rate. In addition, the message characteristics may also include source address, destination address, protocol port number, etc. It should be noted that the message data payload may be the average value of the data payload of each message to be transmitted.

[0070] Optionally, in this embodiment, an analysis module may be pre-configured in the OLT device, and the message characteristics of the message to be transmitted may be obtained based on the analysis module. Among them, the analysis module may obtain the message to be transmitted through the OLT device uplink port and the PON port, and start monitoring the message to be transmitted, and then obtain the message characteristics of the message to be transmitted. Specifically, the security management module in the OLT device may use a mirroring method to mirror the uplink and downlink messages through the OLT device uplink port and the PON port to the analysis module, so that the analysis module obtains the message to be transmitted and monitors the message to be transmitted. Optionally, the analysis module in this embodiment may be configured on the smart board of the OLT device.

[0071] S203: Determine a target suppression threshold parameter of the OLT device according to the message characteristics of the message to be transmitted.

[0072] Among them, the suppression threshold parameter refers to the threshold used to limit broadcast or multicast traffic; these parameters are set to prevent network congestion and improve network performance. The suppression threshold parameters of traditional OLT devices are fixed values ​​with low values. The processing method for broadcast or multicast messages generally adopts one-way over-threshold discard, which can be used to limit broadcast network message attacks or unnecessary access messages, but also makes the industrial PON network unable to transmit high-frequency EtherCAT type messages. The target suppression threshold parameter refers to the suppression threshold parameter that needs to be specified for the OLT device.

[0073] As an optional implementation of the embodiment of the present application, a target suppression threshold parameter of the OLT device is determined according to a transmission frequency and a message data payload in message characteristics of the message to be transmitted.

[0074] As another optional implementation of the embodiment of the present application, the message features of the message to be transmitted are input into an intelligent analysis tool, and the intelligent analysis tool outputs the target suppression threshold parameter of the OLT device. The intelligent analysis tool can be a trained neural network model.

[0075] S204: Transmit the message to be transmitted based on the target suppression threshold parameter.

[0076] Optionally, in this embodiment, after the target suppression threshold parameter is configured in the OLT device, the message to be transmitted is transmitted normally under the target suppression threshold parameter.

[0077] The above-mentioned message transmission method obtains the message type of the message to be transmitted. When the message type is a target type, the message characteristics of the message to be transmitted are obtained. According to the message characteristics of the message to be transmitted, the target suppression threshold parameter of the OLT device is determined. Based on the target suppression threshold parameter, the message to be transmitted is transmitted. The present application can obtain the message type of the message to be transmitted. When the message type is a target type (for example, an EtherCAT type message), the message characteristics of the message to be transmitted can be obtained, and the target suppression threshold parameter of the OLT device can be flexibly determined according to the message characteristics of the message to be transmitted. Based on the target suppression threshold parameter, the message to be transmitted is transmitted. Compared with the traditional method of using fixed suppression threshold parameters, when the OLT device transmits EtherCAT type messages, packet loss is prone to occur. The present application can flexibly determine the suppression threshold parameter of the OLT device according to the message characteristics, which can effectively avoid the occurrence of packet loss when transmitting EtherCAT type messages, so that the industrial PON network can carry the transmission of EtherCAT type messages while ensuring network security.

[0078] In one embodiment, to increase network security, such as Figure 3 As shown, an optional implementation of obtaining the message feature of the message to be transmitted in S201 includes:

[0079] S301, obtaining the source address of the message to be transmitted.

[0080] The source address refers to the MAC (Media Access Control) address of the source device that generates the message to be transmitted.

[0081] As an optional implementation of the embodiment of the present application, a source device that generates a message to be transmitted is obtained, and a device MAC address of the source device is determined to obtain the source address of the message to be transmitted.

[0082] As another optional implementation of the embodiment of the present application, the message to be transmitted is parsed to obtain the message header of the message to be transmitted, and the source address of the message to be transmitted is obtained according to the field content in the message header. Specifically, the source address of the message to be transmitted is determined according to the source address in the message header of the message to be transmitted (as shown in Table 1).

[0083] S302: When the source device pointed to by the source address is a whitelist device, obtain a message feature of the message to be transmitted.

[0084] Optionally, in this embodiment, before executing the message transmission method of the present application, during the online link establishment and activation process of the OUN device, it is necessary to report the message forwarding capability and its own MAC address to the OLT device. The OLT device includes this information of the ONU, and adds the MAC address of each ONU device to the whitelist, and the device corresponding to the MAC address in the whitelist is used as the whitelist device.

[0085] Optionally, in this embodiment, the source address is matched with each MAC address in the whitelist. If the match is successful, it indicates that the source device pointed to by the source address is a whitelist device. On this basis, the message characteristics of the message to be transmitted are obtained.

[0086] In this embodiment, the source address of the message to be transmitted is obtained. When the source device pointed to by the source address is a whitelist device, the message characteristics of the message to be transmitted are obtained. In this embodiment, the judgment process of the whitelist device is added, and the message characteristics are obtained only for the message to be transmitted generated by the whitelist device, which not only reduces unnecessary resource waste, but also improves network security.

[0087] In one embodiment, in order to more accurately determine the target suppression threshold parameter, such as Figure 4 As shown, an optional implementation of S203 includes:

[0088] S401, adjusting the current suppression threshold parameter of the OLT device according to the message characteristics of the message to be transmitted to obtain a target suppression threshold parameter.

[0089] The current suppression threshold parameter refers to the suppression threshold parameter currently being used by the OLT device, which is generally an initial suppression threshold parameter set manually or by a machine.

[0090] Optionally, in the present embodiment, each ONU device needs to upload its own message forwarding capability to the OLT device during the initial online link establishment and activation process. Specifically, the message forwarding capability of the device can be uploaded to the OLT device through the OMCI extended protocol or the extended OAM protocol. Taking the OMCI protocol as an example, the ONU ME capability set field can be extended, and an ONU Packet forwarding capability field can be added under the existing ONU capability ME field. Under the newly added field, the message forwarding capability of the ONU device under broadcast, multicast, and unicast can be reported. For example, each packet length occupies 3 bytes (24 bits) and the value can be:

[0091]

[0092] It should be noted that the message transmission method of the present application is mainly used when the type of message to be transmitted is a broadcast message. Therefore, the message forwarding capability mainly refers to the broadcast message forwarding capability.

[0093] As an optional implementation of the embodiment of the present application, according to the message characteristics of the message to be transmitted and the message forwarding capability of the ONU device associated with the OLT device, the current suppression threshold parameter of the OLT device is adjusted to obtain the target suppression threshold parameter. The message forwarding capability refers to the ability of the ONU device to forward broadcast or multicast messages.

[0094] Specifically, according to the message characteristics of the message to be transmitted (for example, message data payload, transmission frequency and transmission rate, etc.), determine the initial suppression threshold parameter (the setting requirement of the initial suppression threshold parameter is that the message to be transmitted can be transmitted normally without packet loss). Obtain the broadcast message forwarding capability of the OUN device associated with the OLT message. According to the initial suppression threshold parameter and the broadcast message forwarding capability of the OUN device associated with the OLT message, obtain the target suppression threshold parameter. For example, the target suppression threshold parameter is required to be 70%, 80%, 90%, etc. of the broadcast message forwarding capability of the ONU device. It should be noted that the target suppression threshold parameter can be repeatedly optimized and corrected to finally obtain the optimal target suppression threshold parameter.

[0095] As another optional implementation of the embodiment of the present application, according to the message characteristics of the message to be transmitted and the message forwarding capability of the ONU device associated with the OLT device, the current suppression threshold parameter of the OLT device is adjusted to obtain the first suppression threshold parameter. According to the suppression threshold parameter adjustment record in the preset historical period, the first suppression threshold parameter is adjusted to obtain the target suppression threshold parameter.

[0096] It should be noted that, in this embodiment, according to the message characteristics of the message to be transmitted and the message forwarding capability of the ONU device associated with the OLT device, the current suppression threshold parameter of the OLT device is adjusted to obtain the specific method of the first suppression threshold parameter. The method for determining the target suppression threshold parameter in the previous embodiment can be referred to, and will not be repeated here.

[0097] In this embodiment, the first suppression threshold parameter is adjusted according to the suppression threshold parameter adjustment record in a preset historical period to obtain the target suppression threshold parameter. The preset historical period can be the previous day, the previous week, the previous month, etc. Specifically, the predicted suppression threshold parameter can be determined according to the suppression threshold parameter adjustment record in the preset historical period in combination with the intelligent analysis model. Based on the predicted suppression threshold parameter, the first suppression threshold parameter is adjusted to obtain the target suppression threshold parameter. For example, the average of the predicted suppression threshold parameter and the first suppression threshold parameter is used as the target suppression threshold parameter.

[0098] Since message transmission has certain regularity, when determining the target suppression threshold parameter, the target suppression threshold parameter can be determined more efficiently and accurately according to the actual situation and historical data.

[0099] It should be noted that, in the present application, the target suppression threshold parameter of the OLT device can be determined based on the message characteristics of the message to be transmitted, and the analysis module in the above embodiment can be executed and processed. The analysis module feeds back the execution processing result to the security management module of the OLT device, and the security management module adjusts the current suppression threshold parameter of the OLT device according to the execution processing result of the analysis module to obtain the target suppression threshold parameter.

[0100] In this embodiment, according to the message characteristics of the message to be transmitted, the current suppression threshold parameter of the OLT device is adjusted to obtain the target suppression threshold parameter. In this embodiment, the current suppression threshold parameter can be dynamically adjusted according to the real-time transmission of the message to obtain the target suppression threshold parameter, which can be applied to the transmission of messages in various business scenarios, can realize the normal transmission of the message to be transmitted, and can effectively avoid the occurrence of packet loss.

[0101] In one embodiment, after transmitting the message to be transmitted based on the target suppression threshold parameter, such as Figure 5As shown, another optional implementation of a message transmission method includes:

[0102] S501, after detecting that the transmission of the message to be transmitted is completed, obtaining a preset recovery time.

[0103] The preset recovery time refers to the recovery time of the suppression threshold parameter of the OLT device, for example, 10S.

[0104] Optionally, in this embodiment, a preset recovery time is stored in the OLT device. After detecting that the transmission of the message to be transmitted is completed, the preset recovery time is obtained. Optionally, after detecting that the transmission of the message to be transmitted is completed, the analysis module in the OLT device sends a message transmission completion message to the security management module of the OLT device, and after receiving the message transmission completion message, the security management module obtains the preset recovery time.

[0105] S502: After a preset restoration time, the target suppression threshold parameter is restored to the current suppression threshold parameter.

[0106] Optionally, the security management module of the OLT device in this embodiment obtains the current duration, and after the current duration is equal to the preset recovery duration, restores the target suppression threshold parameter to the current suppression threshold parameter. The current duration refers to the duration from the current moment to the time when the message transmission end message is received.

[0107] In this embodiment, after detecting that the transmission of the message to be transmitted has ended, a preset recovery time is obtained. After the preset recovery time, the target suppression threshold parameter is restored to the current suppression threshold parameter. In this embodiment, after detecting that the transmission of the message to be transmitted has ended, the target suppression threshold parameter can also be restored to the current suppression threshold parameter after the preset recovery time, thereby realizing intelligent recovery of the suppression threshold parameter and ensuring network security.

[0108] In one embodiment, if Figure 6 As shown, another optional implementation of a message transmission method includes:

[0109] S601: Obtain the message type of the message to be transmitted.

[0110] S602: When the message type is a target type, obtain a source address of the message to be transmitted.

[0111] S603: When the source device pointed to by the source address is a whitelist device, obtain a message feature of the message to be transmitted, wherein the message feature includes at least one of a message data payload, a transmission frequency, and a transmission rate.

[0112] S604: According to the message characteristics of the message to be transmitted and the message forwarding capability of the ONU device associated with the OLT device, adjust the current suppression threshold parameter of the OLT device to obtain a first suppression threshold parameter.

[0113] S605: Adjust the first suppression threshold parameter according to the suppression threshold parameter adjustment record in a preset historical period to obtain a target suppression threshold parameter.

[0114] S606: Transmit the message to be transmitted based on the target suppression threshold parameter.

[0115] S607: After detecting that the transmission of the message to be transmitted is completed, obtain a preset recovery time.

[0116] S608: After a preset restoration time, the target suppression threshold parameter is restored to the current suppression threshold parameter.

[0117] In this embodiment, the message type of the message to be transmitted is obtained. When the message type is a target type, the message characteristics of the message to be transmitted are obtained. According to the message characteristics of the message to be transmitted, the target suppression threshold parameter of the OLT device is determined. Based on the target suppression threshold parameter, the message to be transmitted is transmitted. The present application can obtain the message type of the message to be transmitted. When the message type is a target type (for example, an EtherCAT type message), the message characteristics of the message to be transmitted can be obtained, and the target suppression threshold parameter of the OLT device can be flexibly determined according to the message characteristics of the message to be transmitted. Based on the target suppression threshold parameter, the message to be transmitted is transmitted. Compared with the traditional method of using fixed suppression threshold parameters, when the OLT device transmits EtherCAT type messages, packet loss is prone to occur. The present application can flexibly determine the suppression threshold parameter of the OLT device according to the message characteristics, which can effectively avoid the occurrence of packet loss when transmitting EtherCAT type messages, so that the industrial PON network can carry the transmission of EtherCAT type messages while ensuring network security.

[0118] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0119] Based on the same inventive concept, the embodiment of the present application also provides a message transmission device for implementing the message transmission method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more message transmission device embodiments provided below can refer to the limitations on the message transmission method above, and will not be repeated here.

[0120] In one embodiment, by Figure 7 FIG. 2 shows a structural block diagram of a message transmission device in an embodiment. Figure 7 As shown, a message transmission device 1 is provided, the device comprising: a first acquisition module 10, a second acquisition module 20, a first determination module 30 and a transmission module 40, wherein:

[0121] A first acquisition module 10, used to acquire the message type of the message to be transmitted;

[0122] A second acquisition module 20, used to acquire the message characteristics of the message to be transmitted when the message type is the target type;

[0123] A first determination module 30, configured to determine a target suppression threshold parameter of the OLT device according to a message feature of the message to be transmitted;

[0124] The transmission module 40 is used to transmit the message to be transmitted based on the target suppression threshold parameter.

[0125] The above-mentioned message transmission device obtains the message type of the message to be transmitted. When the message type is a target type, the message characteristics of the message to be transmitted are obtained. According to the message characteristics of the message to be transmitted, the target suppression threshold parameter of the OLT device is determined. Based on the target suppression threshold parameter, the message to be transmitted is transmitted. The present application can obtain the message type of the message to be transmitted. When the message type is a target type (for example, an EtherCAT type message), the message characteristics of the message to be transmitted can be obtained, and the target suppression threshold parameter of the OLT device can be flexibly determined according to the message characteristics of the message to be transmitted. Based on the target suppression threshold parameter, the message to be transmitted is transmitted. Compared with the traditional method of using fixed suppression threshold parameters, when the OLT device transmits EtherCAT type messages, packet loss is prone to occur. The present application can flexibly determine the suppression threshold parameter of the OLT device according to the message characteristics, which can effectively avoid packet loss when transmitting EtherCAT type messages, so that the industrial PON network can carry the transmission of EtherCAT type messages while ensuring network security.
