[0003] In the prior art, network latency is usually determined based on the time difference between the transmission time when a network device sends data and the reception time when another network device receives the data.

[0004] However, since the clocks of each network device may not be synchronized, the accuracy of network latency is relatively low when calculating network latency based on the transmission time and reception time determined by each network device itself. Summary of the Invention

[0037] In the following description, specific details such as specific system architectures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0040] In addition, in the description of the specification and appended claims of the present application, the terms "first", "second", "third", etc. are only used for differential description and cannot be understood as indicating or implying relative importance.

[0041] In a modern network environment, whether it is a data center network, a wide area network, or an industrial Internet scenario, the evaluation and optimization of network performance are crucial. As one of the key indicators for measuring network performance, network latency directly affects the quality of various network applications and the user experience.

[0042] Exemplarily, in the field of real-time communication, such as voice calls, video conferences, etc., lower network latency can ensure the smoothness of voice and video, reducing stuttering and latency; in the financial transaction network, tiny latency differences may lead to time differences in transaction execution, thus affecting the success rate and benefits of transactions; in industrial automation scenarios, precise network latency control is crucial for ensuring the collaborative work between industrial devices and the stability of the production process.

[0043] In the prior art, network latency is usually determined based on the time difference between the transmission time when a network device sends data and the reception time when another network device receives data.

[0044] However, since the clocks of each network device may not be synchronized, the accuracy of the network latency is relatively low when calculating the network latency based on the transmission time and reception time determined by each network device itself.

[0045] Based on this, in order to improve the accuracy of network latency, the embodiments of the present application provide a method for detecting network latency of data transmission. This method can be applied to electronic devices such as laptops, ultra-mobile personal computers (UMPCs), netbooks, servers, etc. The embodiments of the present application do not impose any restrictions on the specific types of electronic devices.

[0046] For ease of explanation, in this embodiment, the server is taken as an example of the electronic device. Specifically, a network data acquisition and analysis system can be deployed in the server to periodically obtain the information sent and received by each terminal device to execute the method for detecting network latency of data transmission.

[0047] As an example, taking the determination of the network latency when each terminal device in a local area network sends data as an example, a local area network usually includes multiple terminal devices and a switch device. Generally, when a terminal device sends data to another terminal device, it needs to forward the data through the switch device.

[0048] Specifically, referring to Figure 1 , Figure 1 is a schematic diagram of an application scenario of a method for detecting network latency of data transmission provided by an embodiment of the present application. The data can be sent by terminal device 1 and sequentially pass through switch device 1 and switch device 2, and finally be transmitted to terminal device 2. Moreover, when terminal device 1 sends data, it can determine the transmission timestamp when the data is sent based on the timestamp setting module and determine the time offset between the clock source of terminal device 1 and the master clock source. Then, combined with the corresponding unique identifier, it is stored in the information storage module as the information corresponding to the data. And when the data is sent, this information or the unique identifier in this information can be carried.

[0049] Similarly, when the terminal device 2 receives data, it can determine the reception timestamp at the time of data reception based on the timestamp setting module of the terminal device 2, and determine the time offset between the clock source of the terminal device 2 and the master clock source. Then, combined with the corresponding unique identifier, it is stored in the information storage module as the information corresponding to the data.

[0050] The network data acquisition and analysis system in the server can obtain the above information from the storage modules of each terminal device to calculate the network delay.

[0051] Among them, the numbers of the above terminal devices and switch devices are only one example. In this embodiment, the numbers of terminal devices and switch devices are not limited.

[0052] As an example, the network data acquisition and analysis system can have the ability to manage and control terminal devices and switch devices in the local area network. And the network data acquisition and analysis system can use protocols such as SNMP (Simple Network Management Protocol), Netconf (Network Configuration Protocol), and MQTT (Message Queuing Telemetry Transport) to obtain corresponding information from network devices.

[0053] Exemplarily, the network data acquisition and analysis system can use the Netconf protocol to periodically obtain the following first information and second information. And use the Netconf protocol to complete the device status monitoring and data acquisition of network devices.

[0054] Among them, device status monitoring includes but is not limited to device online status, device port traffic data statistics, device memory and utilization statistics, etc. Data acquisition includes but is not limited to device port counting, device CPU memory data, device online detection, packet reception data, packet transmission data, and clock synchronization GPTP data.

[0055] In another embodiment, the network data acquisition and analysis system can also use the Netconf protocol to implement processing such as traffic information acquisition, error packet statistics, clock synchronization status, and clock synchronization parameters of network devices, which will not be elaborated here.

[0056] Among them, the period can be set according to the actual situation. For example, information acquisition is completed every 10s, which is not limited here.

[0057] In one embodiment, the above terminal device can be any device in the network, such as a computer, a server, a switch, a router, an Internet of Things terminal device, etc. In different network scenarios, the terminal device has different specific referents. For example, in an enterprise local area network, the terminal device can be an office computer; in an industrial Internet of Things scenario, it can be a sensor for collecting environmental data.

[0058] For ease of explanation, please refer to Figure 2 , Figure 2 which shows an implementation flowchart of a method for detecting network delay of data transmission provided by an embodiment of the present application. The method includes the following steps:

[0059] S201. Obtain first information when the first device sends data; the first information includes the transmission timestamp recorded by the first device when sending data, and the first time offset between the clock source of the first device and the master clock source.

[0060] In one embodiment, the above first device can be considered as Figure 1 the terminal device in

[0061] for sending data. Among them, the electronic device can obtain the first information in real time or periodically, and this is not limited.

[0062] Among them, the above data is the information carrier sent by the first device to the network and can be various types of information. For example, the types of data include but are not limited to text, pictures, videos, audio, etc. Or, the data can also be the status data of the system operation, the sensor data collected by the device, etc., and this is not limited.

[0063] The above master clock source is the clock source used as the time reference in the entire network or system. The clock sources of other network devices usually need to be synchronized with the master clock source to ensure the consistency of the entire system time. In different network environments, the selection of the master clock source is usually different. For example, in a local area network, a dedicated time server may be used as the master clock source; in a wide area network, the time provided by a GPS clock or a Network Time Protocol (NTP) server may be used as the master clock source.

[0064] Moreover, the above-mentioned transmission timestamp can be a timestamp generated by the first device based on its own clock source. The first time offset is determined based on the timestamp of its own clock source and the timestamp of the master clock source. For example, the difference between the timestamp of its own clock source and the timestamp of the master clock source can be determined as the above-mentioned first time offset.

[0065] It can be understood that due to certain errors in the clock sources of network devices, the clock source of the first device may be faster or slower than the master clock source. At this time, this difference is the above-mentioned first time offset. Through the first time offset, the timestamp of the first device can be adjusted to be consistent with the timestamp of the master clock source, ensuring consistency in the time reference.

[0066] In one embodiment, the first device can obtain the timestamp of the master clock source from the master clock source based on NTP or PTP (Precision Time Protocol). Then, calculate the above-mentioned first time offset. Alternatively, the device of the master clock source can broadcast the timestamp of the master clock source to each network device in real time, so that each first device can determine the first time offset in real time.

[0067] It can be understood that the first information will be generated correspondingly each time data is sent. Based on this, when there are multiple pieces of data, in order to be able to distinguish the first information corresponding to each piece of data, the first device can also assign a unique identifier to the first information each time the first information is generated and store the corresponding first information. That is to say, the first information not only includes the above-mentioned transmission timestamp and the first time offset, but can also include a unique identifier.

[0068] Moreover, in order to be able to obtain the second information that matches the first information from the second device subsequently, when the first device sends data, the data should at least carry a unique identifier. Then, when the second device receives the data, it can write the unique identifier in the data into the second information and store it as well.

[0069] Finally, when both the first device and the second device store multiple pieces of first information and second information correspondingly, the electronic device can also determine the matching first information and second information based on the unique identifier to determine the network delay.

[0070] In another embodiment, the data can also include the entire first information. At this time, when the second device obtains the data, it can not only generate the second information based on the unique identifier in the first information, but also directly associate and store the first information and the second information. Based on this, the electronic device can directly obtain the associated first information and second information from the second device. Furthermore, there is no need to obtain the first information and the second information from the first device and the second device respectively, and there is no need to match them one by one when there are multiple pieces of data.

[0071] In the embodiments of the present application, the quantity of data, the first information, the second information, and the corresponding acquisition methods are not limited.

[0072] In one embodiment, the electronic device may randomly determine a target network device from multiple network devices, and determine the clock source in the target network device as the master clock source. At this time, the clock sources in the remaining network devices can be regarded as slave clock sources.

[0073] However, since different network devices have different precision requirements for time, there are usually differences in the precision of the clock sources in different network devices. Therefore, if a clock source with poor precision is used as the master clock source, it will lead to a decrease in the precision of the network delay determined based on the first information and the second information subsequently.

[0074] Based on this, in order to improve the precision of the network delay, the electronic device may acquire the clock parameters of the clock sources in each network device; the network devices include switch devices and terminal devices for sending data. Then, determine the master clock source from multiple clock sources based on the clock parameters; the network device corresponding to the master clock source is used to broadcast the time stamp of the master clock source.

[0075] In one embodiment, the above clock parameters are usually used to describe the clock performance of the clock source. Therefore, the clock source with the optimal clock performance can be determined as the master clock source.

[0076] Exemplarily, the above clock parameters include but are not limited to parameters such as the priority, precision, and stability of the clock source. Taking the priority as an example, the electronic device may select the clock source with the highest priority as the master clock source. For example, if the clock sources corresponding to three network devices have priorities of 1, 3, and 2 respectively, and the larger the number, the higher the priority, then the electronic device may determine the clock source with a priority of 3 as the master clock source.

[0077] In another embodiment, when the clock parameters include multiple types, for any clock source, the electronic device may also quantify each clock parameter, and then calculate based on the quantified clock parameters to obtain a parameter value representing the performance of the clock source. Finally, determine the clock source corresponding to the maximum value of the parameter value as the master clock source. In this embodiment, the method for quantifying each clock parameter and calculating the quantified clock parameters is not limited.

[0078] It can be understood that by quantifying multiple clock parameters and calculating the multiple parameters corresponding to any clock source, a parameter value that can comprehensively and accurately evaluate its performance can be obtained. Furthermore, the one-sidedness of selecting the master clock source based only on a single parameter can be avoided, and the precision of the subsequent determined network delay can be improved.

[0079] It should be noted that after the master clock source is determined, the network device corresponding to the master clock source can broadcast the timestamp of the master clock source so that the first device can generate the first information.

[0080] As an example, IEEE802.1AS is developed based on the IEEE1588V2 precise clock synchronization protocol and is called GPTP (Generalized Precision Time Protocol). GPTP is a distributed master-slave structure that can synchronize the clocks in all GPTP networks with the master clock. First, the Best Clock Master Algrothms (BCMA) is used to establish the primary-secondary relationship, which are respectively called the Clock Master (CM) and the Clock Slave (CS). The network devices of each GPTP node can run a GPTP Engine. The PTP adopted by IEEE1588 is transmitted by the IP network of the L3 and L4 layers of the network and distributes clock information through multicast or unicast of IPv4 or IPv6. While GPTP is embedded in the MAC layer hardware and only works at L2. It can directly insert time information into the data frame and transmit it to each network device in the network along with the data frame.

[0081] It should be noted that the terminal device and the switch device support the IEEE 802.1AS protocol, which can make the timestamp reach the synchronization accuracy at the nanosecond level. Furthermore, it ensures the real-time and reliable transmission of network data.

[0082] S202. Obtain the second information when the second device receives the data; the second information includes the reception timestamp recorded by the second device when receiving the data, and the second time offset between the clock source of the second device and the master clock source.

[0083] In an embodiment, the above-mentioned second device can also be Figure 1 the terminal device in. It should be noted that the difference between the first device and the second device is only that: the first device is the data sender, and the second device is the data receiver. That is, when the second device sends data, the second device can also be regarded as the first device, and when the first device receives data, the first device can also be regarded as the second device.

[0084] Among them, the reception timestamp is similar to the above-mentioned transmission timestamp, the clock source of the second device is similar to the clock source of the above-mentioned first device, and the determination method of the second time offset is similar to the determination method of the above-mentioned first time offset, and no detailed description will be given here.

[0085] S203. Determine the network delay when the data is transmitted in the network based on the first information and the second information.

[0086] In one embodiment, since the first time offset is the time difference between the clock source of the first device and the master clock source, the electronic device can correct the transmission timestamp based on the first time offset to obtain the first timestamp. Exemplarily, the above correction methods include, but are not limited to, addition, subtraction, etc., and are not limited thereto.

[0087] As an example, the electronic device can determine the difference between the transmission timestamp and the first time offset as the above first timestamp. Similar to the method of the first timestamp, the electronic device can correct the reception timestamp based on the second time offset to obtain the second timestamp. For example, the difference between the transmission timestamp and the second time offset can also be determined as the above second timestamp. Finally, the electronic device can determine the network latency based on the first timestamp and the second timestamp.

[0088] Specifically, since the first timestamp is the time of data transmission and the second timestamp is the time of data reception, the electronic device can determine the difference between the first timestamp and the second timestamp as the network latency.

[0089] It should be noted that by correcting the transmission timestamp based on the first time offset to obtain the first timestamp, and correcting the reception timestamp based on the second time offset to obtain the second timestamp, and then determining the network latency based on the first timestamp and the second timestamp, the measurement error caused by the time offset between the clock sources of the first device and the second device and the master clock source can be effectively eliminated. The timestamps can be unified to the time reference of the master clock source, improving the accuracy and reliability of network latency calculation.

[0090] In another embodiment, when there are multiple pieces of data, the corresponding first information and second information will also be multiple. At this time, based on the explanation of the unique identifier in the above S201, the electronic device can match the first information and the second information with the same unique identifier. Then, for any set of matched first information and second information, based on the first information and the second information, determine the initial network latency when the data is transmitted over the network. Finally, determine the network latency based on multiple initial network latencies.

[0091] Among them, the method of determining the initial network latency based on the first information and the second information can be to first correct the transmission timestamp based on the first time offset to obtain the first timestamp. Then, correct the reception timestamp based on the second time offset to obtain the second timestamp. Finally, determine the initial network latency based on the first timestamp and the second timestamp.

[0092] It can be understood that since there may be multiple pieces of first information and second information that match, multiple initial network delays will be obtained. At this time, the electronic device may determine the variance value or standard deviation of the multiple initial network delays as the network delay. In this embodiment, the method for determining the network delay based on multiple initial network delays is not limited.

[0093] Exemplarily, the variance value of multiple initial network delays may be determined as the network delay. It should be noted that calculating the network delay using multiple sets of matching first information and second information can comprehensively reflect the time differences during different data transmission processes, avoid the contingency and one-sidedness of single data, and make the measurement of network delay more representative. Moreover, using the variance value as the network delay can intuitively reflect the fluctuation degree of network transmission delay. The smaller the variance, the more stable the network transmission; the larger the variance, the greater the time delay variation in network transmission.

[0094] In this embodiment, by obtaining the first information including the sending timestamp and the first time offset from the master clock source when the first device sends data, the time deviation between the clock source of the first device and the master clock source can be accurately eliminated based on the sending timestamp and the first time offset. Also, by obtaining the second information including the receiving timestamp and the second time offset from the master clock source when the second device receives data, the time deviation between the clock source of the second device and the master clock source can be accurately eliminated based on the receiving timestamp and the second time offset. Based on this, when determining the network delay of data during network transmission based on the first information and the second information, the influence of time offset between the clock sources of different devices can be eliminated, unifying the time of each device to the time reference of the master clock source, and avoiding measurement errors introduced by inconsistent clocks. Furthermore, based on the sending timestamp and the receiving timestamp with measurement errors eliminated, the actual delay situation of data during network transmission can be more truly and accurately reflected, providing a solid foundation for network performance evaluation and optimization.

[0095] To more clearly illustrate the solution in this application, the following uses specific embodiments to elaborate on the solution in this application. For details, refer to Figure 3 , which is a flowchart of the implementation of a network delay detection method for data transmission provided by another embodiment of this application. Taking the electronic device as a server as an example, the server includes a network data collection and analysis system, which can periodically obtain the information sent and received by each terminal device to execute the network delay detection method for data transmission.

[0096] Specifically, the network data collection and analysis system can obtain the clock parameters of the clock sources in each terminal device to determine the master clock source from multiple clock sources based on the clock parameters. At this time, the network device corresponding to the master clock source can broadcast the timestamp of the master clock source in real time.

[0097] After that, when the first device sends data, it can record the transmission timestamp when the data is sent, as well as the first time offset between the clock source of the first device and the master clock source. Moreover, the first device can assign a unique identifier to generate and store the first information. Meanwhile, when sending data, the unique identifier can also be written into the data.

[0098] Similar to the first information, when the second device receives data, it can record the reception timestamp when the data is received, as well as the second time offset between the clock source of the second device and the master clock source. Moreover, the second device can obtain the unique identifier from the data, and then use the reception timestamp, the second time offset, and the unique identifier as the second information and store it.

[0099] Finally, the network data acquisition and analysis system can first obtain multiple pieces of first information and second information from the first device and the second device respectively. Then, it can match the first information and the second information with the same unique identifier. Moreover, for any set of matched first information and second information, based on the first information and the second information, it can determine the initial network delay when the data is transmitted over the network. Finally, the variance value of multiple initial network delays is determined as the network delay.

[0100] In this embodiment, by adopting the above method, the influence of the time offset between the clock sources of different devices can be eliminated, the time of each device can be unified to the time reference of the master clock source, and the measurement error introduced by clock inconsistency can be avoided. Furthermore, based on the transmission timestamp and the reception timestamp with the measurement error eliminated, the actual delay situation of the data during network transmission can be reflected more truly and accurately, providing a solid foundation for network performance evaluation and optimization.
