[0006] Other features and advantages of the present disclosure will become apparent from the following detailed description, or may be learned in part by the practice of the present disclosure.

[0007] The technical solution of the present disclosure is as follows:

[0008] According to one aspect of the present disclosure, a method for monitoring the quality of routing nodes is provided, the method comprising: deploying probes in networks of different operators to simulate traffic usage in each network environment; obtaining a health record through the probes, wherein the health record comprises: upper and lower control limits of the historical average delay of a target path; periodically obtaining the current average delay of a source address and a destination address on the target path through an Internet packet explorer Ping; comparing the current average delay as a quantitative indicator with the upper and lower control limits in the health record; obtaining the IP address of the current routing node on the target path according to a routing tracking operation; and performing abnormality analysis and network optimization on the IP address of the current routing node on the target path according to the comparison result.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] In view of the technical problems existing in the above-mentioned related technologies, an embodiment of the present disclosure provides a method for monitoring the quality of a routing node, so as to solve at least one or all of the above-mentioned technical problems.

[0039] It should be pointed out that the nouns or terms involved in the embodiments of the present application can refer to each other and will not be repeated here.

[0040] In the following, each step of the method for monitoring routing node quality in this exemplary implementation will be described in more detail with reference to the accompanying drawings and embodiments.

[0041] Figure 1 FIG. 2 is a flow chart of a method for monitoring routing node quality in an embodiment of the present disclosure. Figure 1 As shown, the method 100 may include the following steps:

[0042] In step S110 , probes are deployed in networks of different operators to simulate traffic usage in each network environment.

[0043] In step S120, a health record is obtained through a probe, wherein the health record includes: control upper and lower limits of the historical average delay of the target path.

[0044] The historical average delay refers to the average of multiple historical delays detected multiple times in the past cycle. The control upper and lower limits are the upper and lower limits of the delay determined according to the ratio of the historical average delay and the upper and lower limits. If the average delay is between the upper and lower limits, it means that the network performance is normal. If it exceeds the upper limit of the delay, it means that the network performance is abnormal. If it is lower than the lower limit of the delay, it means that the network is excellent.

[0045] In step S130, the current average delay of the source address and the destination address on the target path is periodically obtained through the Internet packet explorer Ping.

[0046] The destination address includes not only the final node address where the data packet arrives but also each hop node passed through to reach the final node address.

[0047] The current average delay refers to the average delay value obtained in a current cycle. In some embodiments of the present disclosure, the current average delay includes multiple current average delays of the source address and each destination address.

[0048] In step S140, the current average delay is used as a quantitative indicator to be compared with the upper and lower control limits in the health record.

[0049] In some embodiments of the present disclosure, if the current average delay is higher than the delay upper limit, it means that the current network performance is poor, and if the current average delay is lower than the delay lower limit, it means that the current network performance is excellent.

[0050] In step S150, the IP address of the current routing node on the target path is obtained according to the route tracking operation.

[0051] Among them, the corresponding route (ie, path) of the data packet across the network can be obtained through the route tracking operation and the IP addresses of various router interfaces on the path can be discovered.

[0052] In step S160, an abnormality analysis and network optimization are performed on the IP address of the current routing node on the target path according to the comparison result.

[0053] In some embodiments of the present disclosure, anomaly analysis is performed on routing paths whose current average delay is higher than an upper delay limit; and network optimization is performed on routing paths whose current average delay is lower than a lower delay limit.

[0054] The present disclosure provides a method for monitoring the quality of routing nodes in an international network across operators. It does not require separate configuration for different operators or different regions, and can realize network quality collection, analysis and statistics for a large number of network addresses, thereby simplifying the routing node quality monitoring process for complex and large international networks.

[0055] Furthermore, the disclosed method realizes automatic data processing through health records and abnormal analysis and network optimization methods, thus saving resource costs consumed in the process of monitoring routing node quality.

[0056] Furthermore, the method disclosed herein combines routing information for analysis, and compared with the method of only analyzing source and destination addresses, has richer analysis information and more accurate analysis and optimization results.

[0057] In some embodiments of the present disclosure, the method for obtaining the health record in step S120 may be, for example, Figure 2 The method steps shown are as follows: Figure 2 As shown, the method 200 includes the following steps:

[0058] In step S210, Ping and route tracking operations are performed periodically to obtain the historical average delay and the IP address of the historical routing node.

[0059] In step S220, the historical average delays obtained in multiple periods are compared with the IP addresses of the historical routing nodes.

[0060] In step S230, the path composed of routing nodes with completely identical IP addresses is regarded as a highly overlapping path, and the historical average delay of the highly overlapping path is regarded as the historical average delay of this path.

[0061] In step S240, the path composed of routing nodes whose IP addresses are not completely consistent is taken as a low-overlapping path, and the path with the smallest historical average delay is taken.

[0062] In step S250, the IP addresses of all historical routing nodes of the complete path and the control upper and lower limits of the historical average delay are obtained according to the comparison result.

[0063] In some embodiments of the present disclosure, in extreme cases, if the paths measured by multiple route tracing operations all have low overlap, the path with the lowest historical average delay is taken as the health record.

[0064] The method of the embodiment of the present disclosure compares the archival data collected in multiple historical periods, takes the data with completely consistent IP paths as archival data, and regenerates the archival data by statistics, splicing and processing the incompletely consistent path data. Compared with the method of directly using archival data in the prior art, the accuracy of the collected data is guaranteed, and the reliability of the routing node quality monitoring method is further improved.

[0065] In some embodiments of the present disclosure, the health record may also include a delay threshold and a packet loss rate threshold determined based on the delay and packet loss rate from the source address to each historical routing node in the complete path, and the autonomous system (AS) number corresponding to each historical routing node.

[0066] Among them, the delay and packet loss rate of the historical routing nodes can be detected through the ping probe.

[0067] The delay threshold and the packet loss rate threshold can be obtained by proportional calculation based on the historical delay and the historical packet loss rate.

[0068] Among them, each routing node's IP address has a corresponding AS number.

[0069] In some embodiments of the present disclosure, step S160 may also be, for example, Figure 3 A flowchart of another method for performing abnormal analysis and network optimization on the IP address of the current routing node on the target path according to the comparison result in the embodiment of the present disclosure is shown. Figure 3 As shown, the method 300 may include the following steps:

[0070] In step S310, the current average delay data of the most recent multiple monitorings are traced back.

[0071] The most recent multiple monitorings may be the most recent multiple monitoring cycles.

[0072] In step S320, if more than 80% of the current average delays are above the control upper limit, an abnormality analysis operation is performed on the IP address of the current routing node on the target path.

[0073] In step S330, if more than 80% of the current average delays are below the control lower limit, a network optimization operation is performed on the IP address of the current routing node on the target path.

[0074] The method of the disclosed embodiment can improve the reliability of routing node quality monitoring results in a complex international network environment.

[0075] In some embodiments of the present disclosure, the abnormality analysis operation may also include analyzing whether the IP address of the current routing node is abnormal and analyzing the network quality from the source address to each routing node. Specifically, it is possible to first analyze whether the IP address of the current routing node on the target path is abnormal; if the IP address of the current routing node on the target path is not abnormal, then analyze whether the current routing node on the target path has a network quality problem.

[0076] In some embodiments of the present disclosure, the method for analyzing whether the IP address of the current routing node on the target path is abnormal can be, for example, Figure 4 The method 400 shown may include the following steps:

[0077] In step S410, if the AS number of the current routing node on the target path changes and the city corresponding to the IP address also changes, it means that the exit of the target path is abnormal.

[0078] In step S420, if the AS number has not changed or the AS number has changed but the city corresponding to the IP address has not changed, it means that the exit of the target path is normal, and continue to analyze whether the order of city nodes passed by the target path within the same AS number is consistent with the order in the health record. If the order is inconsistent, it means that the current routing node has a detour problem.

[0079] For example Figure 5 The routing data is shown. Figure 5 The health profile shown includes: the current average delay of the source address and multiple destination addresses on the target path. The example process of the abnormality analysis method of the embodiment of the present disclosure is as follows: in the current routing data, it is detected that the AS number of the 7th routing node has changed from AS4134 to AS19905 and the city corresponding to the IP address has changed from Beijing to Fujairah, which means that there are abnormalities in the jump point (202.97.14.218) and the subsequent jump points, that is, the exit of the target path is abnormal.

[0080] The method of the disclosed embodiment performs comprehensive logic analysis and detection based on various data source information such as routing node IP addresses and AS numbers, and the monitoring data is comprehensive and the monitoring results are highly credible.

[0081] In some embodiments of the present disclosure, the step of analyzing whether there is a network quality problem on the target path may be, for example, Figure 6 The method 600 shown, specifically, may include the following steps:

[0082] In step S610, the actual delay and actual packet loss rate of the network path from the source address to the detection line of each current routing node are detected, and the actual delay and actual packet loss rate of each detection route are compared with the delay threshold and packet loss rate threshold in the health file.

[0083] Among them, the detection line from the source address to each routing node can be, for example, Figure 5 Each line of the routing data format shown contains network routing data.

[0084] Among them, the current routing node can be, for example, Figure 5 Each row shown detects the jump nodes in the line.

[0085] In step S620, if the network quality of the detection route meets the delay threshold and packet loss rate threshold in the health file, it means that the network quality of the corresponding current routing node is normal.

[0086] Here, satisfying the delay threshold and the packet loss rate threshold means being within a reasonable range of the delay threshold and the packet loss rate threshold.

[0087] In step S630, if the network quality of the detected route does not meet the delay threshold and packet loss rate threshold in the health record, it means that the network quality of the corresponding current routing node is abnormal.

[0088] The failure to meet the delay threshold and the packet loss rate threshold refers to being outside a reasonable range of the delay threshold and the packet loss rate threshold.

[0089] The method of the disclosed embodiment can provide operation and maintenance personnel with network quality data information of upstream and downstream network suppliers, and provide basic data with finer granularity for a comprehensive understanding of network quality.

[0090] In some embodiments of the present disclosure, the network optimization operation may also include: adjusting the upper and lower control limits in the health file according to the current average delay of the current routing node on the target path and adjusting the IP address of the historical routing node in the health file according to the IP address of the current routing node.

[0091] For example, Figure 7 The illustrated method 700 may include the following steps:

[0092] In step S710, the IP address of the current routing node is compared with the IP address of the historical routing node in the health record to see if they are consistent.

[0093] In step S720, if the routing node has not changed compared to the routing node in the health record, the upper and lower control limits in the health record are adjusted according to the most recent average delay.

[0094] In step S730, if the routing node has changed compared with the routing node in the health record, it is determined whether the change is stable, and if it is stable, the complete path in the health record is adjusted.

[0095] Among them, whether the change is stable can be determined by judging whether more than 80% of the routing nodes detected in the detection cycle have changed in the recent period. If more than 80% of the detection results have changed, it means that the change is stable, and the system automatically updates the routing data of the health record; if more than 80% of the detection results have not changed, it means that the change is unstable.

[0096] In step S740, if it is unstable, an optimization suggestion is generated and a manual process is prompted.

[0097] The method of the embodiment of the present disclosure retains the changes in the routing chain and the optimization path through periodic monitoring and self-optimization, gradually depicts the optimization direction of the routing, and makes the optimization result closer to the expected effect.

[0098] Figure 8 FIG. 2 is a flow chart showing another method for monitoring routing node quality in an embodiment of the present disclosure. Figure 8 The method 800 shown can be divided into three stages, including: a monitoring stage, an abnormality analysis stage, and a result processing stage. The monitoring stage includes the following steps:

[0099] In step S802, probes are deployed in networks of different operators to simulate traffic usage in each network environment.

[0100] In step S804, a health record is obtained through the probe, wherein the health record includes: the control upper and lower limits of the historical average delay of the target path.

[0101] In step S806, the current average delay of the source address and the destination address on the target path is periodically obtained through the Internet packet explorer Ping.

[0102] In step S808, the IP address of the current routing node on the target path is obtained according to the route tracking operation.

[0103] In step S810, compare whether the current average delay is better than the upper and lower control limits in the health record.

[0104] Among them, better than the upper and lower control limits means that the current average delay is below the lower control limit.

[0105] In some embodiments of the present disclosure, the methods of step S802 and step S810 may be, for example, Figure 1 The specific manner of each step in the method 100 shown has been described in detail in the embodiment of the method, and will not be repeated here.

[0106] If the current average delay is better than the upper and lower control limits in the health record, it will directly enter the result processing stage.

[0107] If the current average delay is not better than the upper and lower control limits in the health record, the abnormal analysis phase will be entered, which mainly includes the following steps:

[0108] In step S812, it is determined whether the exit on the target path is normal.

[0109] In some embodiments of the present disclosure, whether the exit of the target path is normal can be determined by comparing whether the AS number of the current routing node and the city corresponding to the IP address have changed. Specifically, if the AS number changes and the city corresponding to the IP address also changes, it means that the exit of the target path is abnormal; if the AS number does not change or the AS number changes but the city corresponding to the IP address does not change, it means that the exit of the target path is normal.

[0110] In step S814, it is determined whether the target path has a detour problem.

[0111] In some embodiments of the present disclosure, it is possible to determine whether the target path has a detour problem by comparing the city node sequence in the same AS number with the city node sequence in the health file. Specifically, if the city node sequence in the same AS number is consistent with the city node sequence in the health file, it means that there is no detour problem; if they are inconsistent, there is a detour problem.

[0112] In some embodiments of the present disclosure, the methods of step S812 and step S814 may be, for example, Figure 4 The specific manner of each step in the method 400 shown has been described in detail in the embodiment of the method, and will not be repeated here.

[0113] In step S816, the network quality of each node is detected.

[0114] In some embodiments of the present disclosure, the network quality of each node can be detected by comparing the actual delay and actual packet loss rate of the network path from the source address to the detection line of each routing node with the delay threshold and packet loss rate threshold in the health file. Specifically, for example, Figure 6 The specific manner of each step in the method 600 shown has been described in detail in the embodiment of the method, and will not be repeated here.

[0115] In the result processing stage, the following steps are mainly included:

[0116] In step S818, a monitoring alarm is generated according to the abnormality analysis result.

[0117] In step S820, if the conclusion obtained during the monitoring phase is that the current average delay is better than the upper and lower control limits in the health record, a network optimization suggestion is directly generated.

[0118] Among them, network optimization recommendations include updating health record data.

[0119] In some embodiments of the present disclosure, the method of step S820 may be, for example, Figure 7 The specific manner of each step in the method 700 shown has been described in detail in the embodiment of the method, and will not be repeated here.

[0120] Fig. 9 A schematic diagram of a routing node quality monitoring device according to an embodiment of the present disclosure is shown. Fig. 9 As shown, the device 900 includes:

[0121] The probe deployment module 910 is used to deploy probes in the networks of different operators to simulate the traffic usage in each network environment; the archive data acquisition module 920 is used to obtain the health archive through the probe, wherein the health archive includes: the control upper and lower limits of the historical average delay of the target path; the Internet packet explorer module 930 is used to periodically obtain the current average delay of the source address and the destination address on the target path through the Internet packet explorer Ping; the average delay comparison module 940 is used to compare the current average delay as a quantitative indicator with the control upper and lower limits in the health archive; the route tracking module 950 is used to obtain the IP address of the current routing node on the target path according to the route tracking operation; and the analysis and optimization module 960 is used to perform abnormal analysis and network optimization on the IP address of the current routing node on the target path according to the comparison results.
