Description

Link quality monitoring method and device, electronic equipment and computer readable storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a link quality monitoring method and apparatus, an electronic device, and a computer-readable storage medium.

Background

IP (Internet Protocol) network link quality plays a key role in network transmission performance. The link quality degradation will cause transmission error to increase, resulting in an increase of Cyclic Redundancy Check (CRC) error messages, and thus causing the messages to be discarded by the forwarding device. If the packet loss rate of the network and the service is increased, the service quality of the service will be affected.

The traditional method adopts a mode of uploading an equipment abnormity alarm file to a log server, and alarms are generated when equipment detects that error codes exceed the limit and the receiving/sending optical power of an optical module is abnormal. When the equipment detects that the error code exceeds the limit or the receiving/transmitting optical power of the optical module is abnormal, an alarm is generated in the log. Because the log server stores massive real-time and non-real-time redundant alarm information, the real effective alarm information is difficult to obtain.

Therefore, when a network fails, the fault is usually diagnosed and checked by means of a log server, and it is difficult to directly perform fault early warning and fault real-time positioning by the log server. The hysteresis effect of monitoring link quality anomalies by the log server is very significant.

It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure.

According to the technical scheme provided by the embodiment, on one hand, the target port sends related data to the acquisition and analysis system when the number of CRC (cyclic redundancy check) error packets or the receiving optical power or the sending optical power changes, so that the acquisition and analysis system can acquire the number of CRC error packets, the receiving optical power and the sending optical power in the target port in real time, and the link quality of a target link can be judged in real time; on the other hand, the data volume of the collected report is reduced through the inhibiting function.

Referring to fig. 4, a link quality monitoring method provided by an embodiment of the present disclosure may include the following steps.

Referring to fig. 5, a link quality monitoring method provided by an embodiment of the present disclosure may include the following steps.

Referring to fig. 6, the CRC error packet data amount shows a gradually increasing trend in a period of time by analyzing the CRC error packet data amount by the collecting and analyzing system.

Step S506, the collecting and analyzing system analyzes the received optical power, and determines that the received optical power deviates from the first normal range.

Fig. 7 is a graph illustrating a trend of optical power according to an exemplary embodiment.

Referring to fig. 7, the above-described first normal range may be a range determined according to the set upper and lower normal limits.

In some embodiments, if the collection and analysis system analyzes that the CRC error packet data amount shows a gradually increasing trend over time, the collection and analysis system analyzes the received optical power of the destination port to determine whether the received optical power has deviated from the first normal range within the period of time (e.g., the received optical power has been completely lower than the lower normal limit or higher than the upper normal limit within the period of time, or the received optical power has been lower than the lower normal limit and higher than the upper normal limit within the period of time by more than a target threshold).

Step S508, acquiring a link abnormality of a target link corresponding to the target port determined by the analysis system, where the link abnormality is caused by an optical module in the target network.

In some embodiments, if the CRC packet error number of the target port shows a gradually increasing trend and it is determined that the received optical power deviates from the first normal range, it is determined that a link abnormality occurs in a target link corresponding to the target port, and the link abnormality is caused by an optical module in the target network.

In some embodiments, the reported CRC error packet data and the received and transmitted optical power data of the optical module are subjected to correlation analysis, and if the CRC error packet number is gradually increased and the received optical power of the optical module deviates from a normal range (too strong or too weak), a link quality abnormal trend possibly caused by the optical module problem can be preliminarily determined;

Step S806, the collecting and analyzing system analyzes the received optical power, and determines that the frequency of the received optical power exceeding the first normal range is greater than a third threshold.

In some embodiments, if it is determined that the frequency with which the number of CRC error packets exceeds the first threshold within the target time period is greater than the second threshold, the acquisition and analysis system may continue to analyze the received optical power.

Step S808, collecting link anomalies occurring in the target link corresponding to the target port determined by the analysis system, where the link anomalies are caused by an optical module in the target network.

In some embodiments, if it is determined that the frequency of the CRC packet error number exceeding the first threshold in the target time period is greater than the second threshold, and the frequency of the received optical power exceeding the first normal range is greater than the third threshold, it is determined that an abnormality occurs in the target link corresponding to the target port, and the link abnormality is caused by an optical module in the target network.

In some embodiments, if an alarm that CRC error packet data exceeds a threshold is frequently received and an alarm that received optical power exceeds a threshold is frequently received, it may be basically determined that link quality is abnormal due to an optical module problem.

Step S906, the collecting and analyzing system analyzes the received optical power, and determines that the received optical power is within a first normal range.

In some embodiments, if the number of CRC error packets is determined not to exceed the first threshold and the number of CRC error packets shows a gradually increasing trend after the acquisition and analysis system analyzes the number of CRC error packets, the acquisition and analysis system may continue to analyze the received optical power to determine whether the received optical power is within the first normal range.

Step S908, the link abnormality of the target link corresponding to the target port determined by the acquisition and analysis system is caused by improper configuration of the target port or poor contact of the target port.

In some embodiments, if it is determined that the CRC number of erroneous packets is in a gradually increasing trend and the received optical power of the target port is within the first normal range after the acquisition and analysis system analyzes the CRC number of erroneous packets, it is determined that a link abnormality occurs in the target link corresponding to the target port, and the link abnormality is caused by improper configuration of the target port or poor contact of the target port.

In some embodiments, if the number of CRC error packets is gradually increased and the receiving optical power of the optical module is in a normal range, the problems of improper port configuration, poor port contact and the like may be considered, and further troubleshooting is required.

Step S1106, the collecting and analyzing system determines that the transmitting optical power affects the receiving of the data by the receiving port at the opposite end of the target port.

In some embodiments, if an alarm that the transmitted optical power exceeds the threshold is frequently received, there may be a problem that the port of the peer device is affected to receive data, and further checking for a fault is required.

Fig. 12 is a flow chart illustrating a method of link quality monitoring according to an example embodiment.

Firstly, a collection and analysis system or a management and control system configures key data reporting subscription of a target port of target equipment reflecting link quality, and the subscription comprises the following steps: the CRC packet error number, the receiving optical power and the sending optical power of the optical module, the alarm report that the CRC packet error number exceeds a set threshold value, and the alarm report that the receiving optical power and the sending optical power of the optical module exceed the set threshold value.

The link quality detection method may include the steps of:

step (I): the device data collection reporting mode of the target port of the target device may adopt any one or more of the following modes:

(1) Periodic (periodic) reporting: the target port reports the acquired data such as the CRC error packet number, the receiving optical power of the optical module, the transmitting optical power and the like to the control system periodically, the reporting period is configurable, and the minimum reporting period of a sub-second level should be supported. In order to reduce the data amount of the collection report, a redundancy suppression function should be supported, that is, if the collected data value is not changed, the data is not reported, but a heartbeat monitoring message needs to be periodically reported to the management and control system, which indicates that the subscription can keep the connection state.

(2) Change (on-change) reporting: the target port reports the acquired data such as CRC packet error quantity, receiving optical power of an optical module, sending optical power and the like after the first reporting, and reports the data when the subsequent data value changes. In order to reduce the amount of data reported due to frequent data changes, a report suppression function is also supported, that is, a suppression timer is set, and the data reporting is triggered when the timer times out.

(3) Triggering and reporting a threshold value: and presetting a CRC (cyclic redundancy check) packet error quantity threshold, a receiving optical power threshold and a sending optical power threshold of an optical module, triggering reporting when the acquired data reaches or exceeds the thresholds, wherein the reporting frequency can be set.

The network device collects the data and packages a telemetrology (a remote data collection technology for monitoring the performance and faults of the device) message according to a subscription configuration and data reporting mode, carries the collected timestamp information and the collected node information, and reports the timestamp information and the collected node information to the management and control system.

Referring to fig. 12, a joint reporting mode of periodic reporting and threshold triggered reporting may be used to report data such as the number of CRC error packets, the received optical power of the optical module, and the transmitted optical power.

Step (II): the step of the management and control system performing real-time intelligent processing on the reported link quality data comprises at least one of the following modes:

(1) The reported CRC error packet data and the received and transmitted optical power data of the optical module are subjected to correlation analysis, and if the CRC error packet number is gradually increased and the received optical power of the optical module deviates from a normal range (too strong or too weak), as shown in fig. 6, a link quality abnormal trend possibly caused by the problem of the optical module can be preliminarily determined.

(2) If the alarm that the CRC error packet data exceeds the threshold value is frequently received and the alarm that the received optical power exceeds the threshold value is frequently received, the abnormal link quality caused by the optical module problem can be basically determined.

(3) If the number of CRC error packets is gradually increased and the received optical power of the optical module is in a normal range, the problems of improper port configuration, poor port contact and the like can be considered, and further troubleshooting is required.

(4) If the alarm that the received optical power exceeds the threshold value is frequently received and the CRC error packet number is in a trend of gradually increasing, the link quality abnormity caused by the optical module problem can be basically determined.

(5) If an alarm that the transmitted optical power exceeds the threshold value is frequently received, the problem that the receiving port of the opposite terminal equipment receives data may be influenced, and further troubleshooting is needed.

Step (three): real-time visual presentation of link quality status by the management and control system (as shown in fig. 13):
