Understandably, "first\second\third" can be interchanged in a specific order or sequence when permitted, so that the embodiments of the application described here can be It is implemented in an order other than that shown or described here.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of this application. The terminology used herein is only for the purpose of describing the embodiments of the application, and is not intended to limit the application.

In order to better understand the associated performance detection method, device, equipment, and computer-readable storage medium provided in the embodiments of this application, first, the implementation of the associated performance detection method in the related art and the existing problems will be analyzed and explained. .

At present, there is a way to detect the performance of the road. In a series of numbered documents (RFC, Request For Comments) 8321, a statistical method based on color marking is introduced. This method is used to color business packets. Divide business messages into different blocks, and then perform packet loss statistics based on different blocks. Figure 1 is a schematic diagram of the implementation process of the associated performance detection method in the related art. As shown in Figure 1, the method includes:

In step S101, the sending end alternately dyes the detected service flow characteristic fields according to a certain period, and at the same time counts the performance data of the service flow sent in this period, and reports it to the centralized detection unit.

In step S102, the receiving end counts the coloring performance data of the characteristic fields of the detected service flow in this period according to the same period of the sending end, and reports it to the centralized detection unit.

In the related art, data such as packet loss rate and time delay of the associated performance test are reported separately based on the sending end and the receiving end, and the receiving end and the sending end need to agree on the same period.

In step S103, the centralized detection unit counts and calculates the performance data of the corresponding service flow based on the performance data reported by the sending end and the receiving end, and calculates the packet loss rate and delay data of a certain period according to the performance data.

In step S103, the detection period of the sending end and the receiving end and the data corresponding to the detection period must be able to match, so that the centralized detection unit can correctly calculate the packet loss rate and delay data of a certain period.

In related technologies, in order to achieve the detection cycle and the data matching corresponding to the detection cycle, the sender and the receiver need to agree to adopt a unified dyeing flip cycle, such as both flipping in a whole second, or both flipping in half a second, in addition, the sender and the receiver In addition to reporting performance data, the terminal also needs to report the period value, for example, the i-th period, so that the centralized detection unit can achieve accurate matching.

However, the disadvantage of the associated performance detection scheme in the related technology is that the sending end and the receiving end equipment must adopt a uniform cycle time. If the cycle time of the two is inconsistent, the detection will be inaccurate or completely wrong. For example, the sender flips in the whole second, and the receiver thinks it flips in half a second. Therefore, if the detection is not performed for the full second flip, an error in the detection result will occur. However, if the statistics of the number of cycles of the sending end and the receiving end are inconsistent, the sending end considers it to be the i-th cycle, and the receiving end considers it to be the i+1th cycle, the centralized detection unit will make an error when performing performance detection. These problems have affected the flexibility and accuracy of the deployment of road-associated performance detection.

Based on the problems in related technologies, an embodiment of the present application provides a method for detecting the associated performance, which is applied to a second device, where the second device may be a receiving end device in a detection system, and the detection system is also Including the first device (transmitting device) and the detection device. The detection device can be the centralized detection unit mentioned in other embodiments. The detection unit can be used for interaction between two devices, and the centralized detection unit can be used for communication between two or more devices. Interactively, the centralized detection unit can also include multiple detection units, and can also refer to an upgraded version of the detection unit. The method provided in this embodiment can be implemented by a computer program, and when the computer program is executed, each step in the method provided in this embodiment is completed. In some embodiments, the computer program may be executed by a processor in the receiving end device. FIG. 2 is a schematic flowchart of a method for detecting the associated performance provided by an embodiment of the application. As shown in FIG. 2, the method includes:

Step S201: The second device receives a service packet marked by a cycle sent by the first device.

Wherein, the marking information of the business packets in the same period is the same, and the marking information of the business packets in adjacent periods is different.

In the embodiment of the present application, the first device is the sending end device in the network associated performance detection system, and the second device is the receiving end device in the network associated performance detection system. In the embodiment of the present application, the first device is the receiving end device in the network associated performance detection system. A device and the second device implement time synchronization based on a time synchronization protocol. The time synchronization protocol may be a Precision Time Protocol (PTP) protocol. In this case, both the first device and the second device need to support the PTP protocol. After the first device and the second device achieve precise time synchronization based on PTP, the time error between the first device and the second device is within microseconds.

The cycle may be sent to the first device together with the detection instruction when the detection device sends the detection instruction, or may be determined by the controller of the first device itself. After the period is determined, the first device marks the first performance data based on the period. The period duration of the period is equal, and for example, the period duration is 1 second (s, second).

In the embodiment of the present application, the mark includes first mark information and second mark information. The first mark information and the second mark information are different. In the embodiment of the present application, the mark information may be a colored mark. The colored bits in the service message in a cycle are colored and marked to distinguish different cycles, and the colored bits refer to bits that perform characteristic identification on the service message. Taking the coloring position of the business packet as two coloring positions as an example, including coloring position 1 and coloring position 2, set the value of coloring position 1 to 0 and the value of coloring position 2 to 1. In the embodiment of the present application, when the service message is colored and marked, it is alternately marked according to a preset cycle. Exemplarily, the marked service message includes the first cycle, the second cycle, the third cycle, and the fourth cycle. The coloring bit No. 1 of the business message in the first cycle is colored, and the business message in the second cycle is colored. The coloring bit 2 of the text is colored, the coloring bit 1 of the service packet in the third cycle is colored, and the coloring bit 2 of the service packet in the fourth cycle is colored. Correspondingly, the marking information in the first cycle can be represented by 0, the marking information in the second cycle can be represented by a value of 1, the marking information in the third cycle can be represented by 0, and the marking information in the fourth cycle can be represented by Use 1 to represent.

Step S202: The second device determines the cycle rollover point of each cycle based on the marking information of the service message.

In the embodiment of this application, since the period duration is the same and the marking information of the service packets in the same period is the same, the marking information of the service packets between adjacent periods is different. Therefore, the receiving end can determine the period of each period according to the marking information. Flip point. Exemplarily, the marking information in the first period may be represented by a value of 0, the marking information in the second period may be represented by a value of 1, the marking information in the third period may be represented by a value of 0, and the marking information in the fourth period It can be represented by a value of 1. When the value of 0 is continuously received, multiple values of 1 are continuously received. At this time, the time of continuously receiving multiple values of 1 can be determined as the cycle rollover point of the first cycle. When the value of 1 is continuously received After that, multiple values of 0 are received continuously, and at this time, the time when multiple values of 0 are received can be determined as the period rollover point of the second period. In the same way, the cycle flip point of the third cycle can be determined. The multiple here can be specifically set according to actual conditions, and setting multiple can prevent the second device from determining the arrival time of the scrambled text as the cycle turning point due to the arrival of the scrambled text. In the embodiment of the present application, the cycle rollover point may also be called the cycle junction point, because the message time of one mark is very short, in milliseconds (ms, millisecond), and the period of message statistics is at least in s. , The two have orders of magnitude difference, therefore, the cycle flip point can have a certain error in determining.

After determining the period reversal points of multiple periods, the period duration can be determined according to the time information of the period reversal points of adjacent periods. According to the time information and period duration of any determined period reversal point, the position of the period reversal point of each period or the time information of the period reversal point can be determined.

Step S203: The second device determines the first performance data of each period according to the period turning point of each period, and records the first time information corresponding to the first performance data of each period.

In the embodiment of the present application, when the rollover point of each period is determined, the first performance data of each period can be counted and the first time information corresponding to the first performance data of each period can be determined. In the embodiment of the present application, the first time information corresponding to the first performance data is the time information when the first performance data is calculated, that is, the time information when the first performance data is generated.

Step S204: The second device sends the first performance data of each cycle and the corresponding first time information to the detection unit, so that the detection unit performs performance according to the first performance data of each cycle and the corresponding first time information. Detection.

In the embodiment of the present application, the detection unit may be integrated with the network management system, or may be an independent device.

In the embodiment of the present application, when the second device determines the first performance data of each cycle and the corresponding first time information, it reports the first performance data of each cycle and the corresponding first time information to the detection unit. The first device will also send the second performance data and the corresponding second time to the detection unit. At this time, the detection device can perform a communication link between the first device and the second device according to the first performance data and the corresponding first time information, the second performance data and the corresponding second time information Carry out associated performance testing.

In the method provided by the embodiments of the present application, when the second device (receiving end device) receives the service packet marked by the first device (sending end device) in a period, the receiving end device can determine the period of each period according to the marking information of the service packet. Cycle overturn point, and determine the first performance data and corresponding time information (time of generation) of each cycle according to the cycle overturn point. When the detection unit receives the first performance data and corresponding time information reported by the receiving end and the corresponding time information reported by the transmitting end When the second performance data and the corresponding time information, since the sending end and the receiving end are time synchronized based on the time synchronization protocol, the detection device can determine according to the time information corresponding to the first performance data and the time information corresponding to the second performance data Corresponding to the first performance data and the second performance data of the period, so as to perform path-associated performance detection on the communication link between the first device and the second device. In the embodiment of the present application, it is not necessary to obtain the cycle number when performing performance testing, and it is not necessary to stipulate that the first device and the second device use the same cycle duration. Therefore, the flexibility of the deployment of the associated performance testing can be improved, and the cycle time can be increased. The matching of the performance data is more accurate.

In the embodiment of the present application, step S202: the determination of the cycle rollover point of each cycle based on the marking information of the service message can be implemented through step S2021 to step S2023 shown in FIG. 3, and each step is performed below in conjunction with FIG. 3. Description.

In step S2021, the second device determines the period reversal point of the first period when the second device continuously receives N pieces of the second flag information after continuously receiving the first flag information.

In the embodiment of the present application, when a service message is received, the marking information carried in the message can be identified, and the period rollover point can be determined according to the marking information of two adjacent periods. For example, the two adjacent periods include the first In the first cycle and the second cycle, the marking information of the first cycle is the first marking information, the marking information of the second cycle is the second marking information, the first marking information is represented by a value of 1, and the marking information of the second cycle is marked by a value of 0 After receiving 1s continuously, N 0s are received continuously. At this time, the period rollover point of the first cycle can be determined, where the period rollover point is the end of the first cycle and the beginning of the second cycle.

In step S2022, the second device determines the period reversal point of the second period when the second device continuously receives the N first flag information after receiving the second flag information continuously.

Continuing the above example, after the second cycle is the third cycle, the second device can determine the cycle rollover point of the second cycle and the third cycle according to the marking information of the second cycle and the third cycle, and the first performance in the second cycle The tag information of the data is a value of 0. When the value of 1 is continuously received, the value of 0 is continuously received. At this time, it can be determined that the value of 0 is received as the cycle turning point of the second cycle and the third cycle.

Step S2023: The second device determines the period reversal point of each period at least according to the period reversal point of the first period and the period reversal point of the second period.

In the embodiment of the present application, the second device determines the period duration at least according to the difference between the first period reversal point and the second period reversal point of two adjacent periods, and sets the start time of any one of the at least two adjacent periods It is the time of the reference period, based on the period length, and then determines the period reversal point of each period. For example: the reference cycle start time is 00:00:15, the cycle duration is 1s, there are 2 cycles after the first cycle, and the cycle rollover points of the two cycles after the first cycle can be determined to be 00:00:16 and 00:00:17.

In some embodiments, the step S2023: the second device determines the period reversal point of each period at least according to the period reversal point of the first period and the period reversal point of the second period, which can be implemented by the following steps:

In step S2023A, the second device determines the period duration at least according to the time information of the period reversal point of the first period and the time information of the period reversal point of the second period.

In the embodiment of the present application, since the period reversal point of the first period and the period reversal point of the second period are adjacent periods, and the period time when the period is marked is the same, in this case, the period reversal point of the first period can be The time information of the time information and the time information of the second cycle rollover point determine the period duration. Illustratively, the time information of the cycle rollover point of the first cycle and the second cycle are 00:00:01 and 00:00:02, respectively. It can be determined that the cycle length is 1s.

In step S2023B, the second device determines the period inversion of each period according to the time information of the period reversal point of the first period and the period duration, or according to the time information of the period reversal point of the second period and the period duration. point.

In the embodiment of the present application, when the period duration is determined, the period reversal point time information of each period can be determined according to the known time information of any reversal point, that is, the reversal point of each period is determined.

In some embodiments, the step S2023B: determining according to the time information of the period turning point of the first period and the period duration, or according to the time information of the period turning point of the second period and the period duration The cycle flip point of each cycle can be achieved through the following steps:

Step S23B1: The second device determines the difference in the number of cycles between each cycle and a reference cycle, where the reference cycle is the first cycle or the second cycle.

Exemplarily, the first cycle is determined as the reference cycle, the cycle rollover point of the first cycle is 0:00:01, that is, 00:00:01, and the cycle duration is 1 second, then the second device can determine the elapsed time After n seconds, it is the nth cycle.

Step S23B2: The second device determines the time difference between each period and the reference period according to the difference between the period duration and the number of periods.

Following the above example, the second device can determine that the difference between the number of cycles of the nth cycle and the number of cycles of the first cycle is n-1. Then, the time difference can be determined by multiplying the period difference by the period duration. In the embodiment of the present application, the time difference is n-1. For example, n is 6, the cycle number difference is 5, and the time difference is 5s.

Step S23B3: The second device determines the period reversal point of each period according to the time information of the period reversal point of the reference period and the time difference corresponding to each period.

After the time difference is determined, the first start time of each period can be determined according to the first start time of the reference period.

Continuing the above example, since the cycle flip point of the first cycle is 00:00:00. The time difference is 5 seconds, so the cycle rollover point time information of the 6th cycle is 00:00:00.

The embodiment of the present application provides a method for detecting the performance of the accompanying path. The method is applied to the detection unit. The method provided in this embodiment can be implemented by a computer program. When the computer program is executed, the method provided in this embodiment is completed. In the various steps. In some embodiments, the computer program may be executed by a processor in the detection device. Fig. 4 is a schematic flowchart of a method for detecting the associated performance provided by an embodiment of the application. As shown in Fig. 4, the method includes:

Step S401: The detection unit obtains the second performance data of each period and the corresponding second time information reported by the first device.

In the embodiment of the present application, when the service message is marked, the second performance data of each period can be counted. Correspondingly, when the second performance data of each period is counted, it can be determined that the second performance data is generated. Time information, that is, the second time information.

Step S402: The detection unit obtains the first performance data of each period and the corresponding first time information reported by the second device.

In the embodiment of the present application, the first performance data of each period is determined based on a service packet marked by a period sent by the first device, and the first device and the second device implement time synchronization based on a time synchronization protocol.

In the embodiment of the present application, when the second device receives the service message and performs performance statistics, the cycle rollover point can be determined according to the marking information. When a cycle rollover point is determined, the first performance data of a cycle can be determined When determining the first performance data of a period, the first time information generated by the first performance data of the period may be recorded. The first performance data of each period and the corresponding first time information are determined according to the reversal point of each period.

In the embodiment of the present application, the first device and the second device implement time synchronization based on a time synchronization protocol. Both the first device and itself support the PTP protocol. After the first device and itself achieve precise time synchronization based on PTP, the time error between the first device and itself is within a microsecond level.

Step S403: The detection unit performs a check between the first device and the second device according to the second performance data of each cycle and the corresponding second time information, the first performance data of each cycle and the corresponding first time information. The communication link carries out the associated performance test.

In the embodiment of the present application, the performance data may be information about the number of packets with a mark, or may be time stamp information. When the performance data is the number of messages, the packet loss rate can be determined based on the message data information, and when the performance data is the time stamp information, the time delay can be determined based on the time stamp information.

In the embodiment of the present application, the first performance data and the second performance data of the corresponding period can be determined through the first time information and the second time information, and then the first performance data and the second performance data of the corresponding period can be determined. Perform path-associated performance detection on the communication link between the first device and the second device.

In the method provided by the embodiment of the present application, since the first device and the second device implement time synchronization based on the time synchronization protocol, when the detection device receives the second time information reported by the first device and the first time information reported by the second device At the time, the first performance data and the second performance data of the corresponding period can be determined according to the second time information and the first time information, so as to perform the path-associated performance detection on the communication link between the first device and the second device . In the embodiment of the present application, the detection device can match the period based on the time information reported by each device, which can improve the flexibility of the deployment of the associated performance detection, and the matching of the performance data in the corresponding period is more accurate.

In some embodiments, step S403: the detection unit compares the first device with the second performance data of each period and the corresponding second time information, the first performance data of each period, and the corresponding first time information. The associated performance test of the communication link between the second devices can be achieved through the following steps:

Step S4031: The detection unit determines the first target time from the respective first time information according to the respective second time information and the respective first time information, and determines the first target time corresponding to the first target time from the respective second time information. The second target time, wherein the difference between the first target time and the second target time is less than a preset duration threshold.

In the embodiment of the present application, the detection unit may determine a first target time from the first time information, and determine a second target time corresponding to the first target time from the respective second time information, and the first target time The difference between the second target time and the second target time is less than the preset duration threshold. The duration threshold is in milliseconds. For example, the preset duration threshold is 100 ms. Of course, the duration threshold can be set according to specific conditions. However, considering that the sending end to the receiving end is transmitted through the network, the network transmission delay is usually within 10ms (including optical fiber transmission delay and node processing delay), so the duration threshold needs to be set to be greater than 10ms.

Continuing the above example, a time is determined in each first moment information reported by the second device, and because the performance detection is usually in seconds, at this time, if a time in each second moment information reported by the first device Within plus or minus 100 ms of the first starting time, it can be determined as the second target time. The example is that the information at the first time includes 00:00:01:030, and the information at the second time includes 00:00:01:010. Because the difference between 00:00:01:010 and 00:00:01:030 is At this time, within 100ms, it can be determined that the first target time is 00:00:01:030, and the second target time is 00:00:01:010. When the first target time and the second target time are determined, it can be determined that the first performance data corresponding to the first target time and the second performance data corresponding to the second target time are performance data of the same period.

Step S4032: The detection unit performs path-associated performance detection on the communication link between the first device and the second device based on the first performance data corresponding to the first target time and the second performance data corresponding to the second target time.

In the embodiments of the present application, in the embodiments of the present application, after synchronization is achieved through PTP, the time error between the receiving end and the transmitting end is within a microsecond level.

In step S502, the first device marks the service message by cycle, counts the second performance data of each cycle, and records the second time information corresponding to the second performance data.

In the embodiment of the present application, the first device alternately marks the service message on a periodic basis. The first device is a sending end device.

Exemplarily, the business message is alternately dyed according to the preset cycle for the setting of the dyeing position 1 and the dyeing position 2, and the value of the dyeing position 1 is set to 0, and the value of the dyeing position 2 is set to 1.

In the embodiment of the present application, the marking information of the service packets in the same period is the same, and the marking information of the service packets in adjacent periods is different.

In the embodiment of the present application, the second time information corresponding to the second performance data is the time information when the second performance data is generated.

Step S503: The first device sends the second performance data and the corresponding second time information to the detection unit.

Step S504: The first device sends the marked service message to the receiving end device.

In the embodiment of the present application, step S502 may be before step S503, or after step S503, and may also be sent at the same time.

Step S505: The second device determines the cycle rollover point of each cycle based on the marking information of the service message.

Continuing the above example, when the first marking information is continuously received and N pieces of the second marking information are continuously received, the cycle turning point of the first cycle is determined; when the second marking information is continuously received, the second marking information is continuously received. When N pieces of the first mark information are received, determine the period rollover point of the second period, where N is greater than a preset value, and the first period and the second period are adjacent; at least according to the first period The period reversal point of and the period reversal point of the second period determine the period reversal point of each period, where N is greater than 1.

Step S506: The second device determines the first performance data of each period and the corresponding first time information according to the period rollover point of each period.

Step S507: The second device sends the first performance data and the corresponding first time information to the detection unit.

Step S508: The detection unit performs a check between the first device and the second device according to the second performance data of each cycle and the corresponding second time information, the first performance data of each cycle and the corresponding first time information. The communication link carries out the associated performance test.

In the method provided by the embodiment of the present application, since the first device and the second device implement time synchronization based on the time synchronization protocol, and after the first device sends the service packet marked by the period to the second device, the second device can Determine the rollover point of each cycle according to the marking information in the service message, and then determine the first performance data of each cycle and the corresponding first time information, and report the first performance data and the corresponding first time information to the detection unit to detect The unit may determine the first performance data and the second performance data of the corresponding period according to the first time information and the second time information, so as to perform path-associated performance detection on the communication link between the first device and the second device. In the embodiment of the present application, the corresponding period is determined according to the time information reported by the first device and the second device when performing performance testing, which can improve the flexibility of the deployment of the associated performance test, and the matching of performance data in the corresponding period can be improved. accurate.

Based on the foregoing embodiments, the embodiment of the present application is providing a method for detecting the performance of the road. FIG. 6 is a schematic flowchart of the method for detecting the performance of the road provided by an embodiment of the application. As shown in FIG. 6, the method includes:

Step S601, the receiving end and the sending end realize time synchronization based on PTP.

In the embodiment of the present application, after synchronization is achieved through PTP, the time error between the receiving end and the sending end is within a microsecond level.

In step S602, the receiving end continues to identify the dyeing mark in the message after receiving the performance test dyed message, and performs message statistics, and judges the turning point of the dyeing based on the statistical result.

In the embodiment of the present application, the turning point of the dyeing can be considered as the cycle junction point.

For example, if the coloring flag of the previous cycle is 0, when the receiving end continues to receive the packets with the coloring flag of 0, and the packets with the coloring flag of 1 are received, it may be the cycle rollover point or out-of-sequence packets. Arrival, after n consecutively received packets with the coloring flag of 1, it can be determined that it is the cycle rollover point. After several cycle flip points are judged, the cycle time information of the sending end can be determined, and the receiving end can record the time position, and then can predict the flip point of the next cycle based on the cycle time information.

Step S603: The sending end and the receiving end report performance data to the centralized detection unit.

In the embodiment of the present application, when the sending end and the receiving end report performance data, they do not need to report the period number, but report the time information when the performance data is generated along with the performance data.

Step S604: After collecting the performance data reported by the sending end and the receiving end, the centralized detection unit compares the periodic time information of the performance data of the two. When the periodic time information of the sending end and the receiving end is within a certain range, the performance of the corresponding period is determined data.

Because, the sending end to the receiving end is transmitted through the network, and the network transmission delay is usually within 10 milliseconds (including the optical fiber transmission delay and the node processing delay). The period of performance statistics is above the second level, at least 1 second, and there is an order of magnitude difference between the two. Therefore, when the time information of the sending end and the receiving end are within a certain range, it can be considered that this group of data is data of the same period. For example, if the data time information deviation between the sending end and the receiving end is within plus or minus 100ms, it is considered to be the data of the same period, so as to realize the matching of the data of each period.

In actual application, the centralized detection unit can be integrated with network management, controller and other equipment, or it can be an independent dedicated centralized detection equipment.

In the method provided by the embodiments of the present application, the receiving end and the transmitting end implement accurate time synchronization based on PTP, and on this basis, the period rollover point of the performance detection data is matched with the period sequence number. When the receiving end receives a message that has been dyed for performance testing, it continues to identify the dye mark in it and make message statistics. Based on the statistical result, it judges the turning point of the dyeing, which is the cycle junction point, and the receiving end determines the cycle time of the sending end. Information, the receiving end can record the cycle time information, and then can predict the rollover point of the next cycle based on the cycle time information. The sending end and the receiving end do not need to report the period number when reporting performance data, but report the time information when the performance data is generated along with the performance data. After the centralized detection unit collects the data reported by the sending end and the receiving end, it compares the time information of the two data. When the periodic time information of the sending end and the receiving end is within a certain range, it is judged that the periodic time information is within a certain range, Determine that the group of data within the cycle time is the data of the same cycle, and then perform performance testing on the data of the same cycle.

In the method provided by the embodiments of the present application, after time synchronization is achieved by the receiving end and the sending end, detection and matching are performed based on time information, and the receiving end and the sending end are no longer required to use the same cycle time, and the same detection cycle is no longer required Numbering, thereby improving the flexibility and accuracy of the deployment of on-road performance testing.
