Description

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

technical field

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

Background technique

IP (Internet Protocol, Internet Protocol) network link quality plays a key role in network transmission performance. Deterioration of link quality will lead to an increase in transmission bit errors, resulting in an increase in Cyclic Redundancy Check (CRC, Cyclic RedundancyCheck) error packets, resulting in packets being discarded by the forwarding device. If the packet loss rate of the network and service increases, the service quality of the service will be affected.

The traditional method adopts the method of uploading the device abnormal alarm file to the log server. When the device detects that the error code exceeds the limit and the optical module receives/transmits the optical power abnormality, an alarm is generated. When the device detects that the error code exceeds the limit or the receiving/transmitting optical power of the optical module is abnormal, an alarm will be generated in the log. Since the log server stores massive real-time and non-real-time redundant alarm information, it is difficult to obtain truly effective alarm information.

Therefore, when a network fault occurs, the log server is usually used to diagnose and troubleshoot the fault, and it is difficult to directly perform fault warning and real-time fault location through the log server. Therefore, the lag effect of monitoring abnormal link quality through the log server is very obvious.

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

First, the acquisition and analysis system or the management and control system configure the target port of the target device to report and subscribe the key data reflecting the link quality, including: the number of CRC error packets, the received optical power of the optical module, the transmitted optical power, and the number of CRC error packets exceeding the set value. Alarm reporting of the threshold value, and alarm reporting of the optical module receiving and sending optical power exceeding the set threshold value.

The above link quality detection method may include the following steps:

Step (1): The device collection data reporting method of the target port of the target device can adopt any one or more of the following methods:

(1) Periodic reporting: The target port will periodically report the collected data such as the number of CRC error packets, the received optical power of the optical module, and the transmitted optical power to the management and control system. The reporting period is configurable and should support sub-second minimum reporting cycle. In order to reduce the amount of data collected and reported, the redundancy suppression function should also be supported, that is, if the collected data value does not change, it will not be reported, but the heartbeat monitoring message needs to be periodically reported to the management and control system, indicating that the subscription will remain connected. .

(2) On-change reporting: The target port will report the data such as the number of CRC error packets, the received optical power of the optical module, and the transmitted optical power for the first time, and only when the subsequent data values change. In order to reduce the amount of data reported due to frequent data changes, the report suppression function should also be supported, that is, a suppression timer is set, and data reporting is triggered when the timer expires.

(3) Threshold trigger reporting: preset CRC error packet number threshold, optical module receiving optical power threshold value, and transmitting optical power threshold value, trigger reporting when the collected data reaches or exceeds the threshold, and the reporting frequency can be set.

The network device collects and encapsulates the above data according to the subscription configuration and data reporting method, and encapsulates the telemetry (a remote data collection technology for monitoring device performance and faults).

Referring to FIG. 12 , periodic reporting and threshold-triggered reporting can be used to report data such as the number of CRC error packets, the received optical power, and the transmitted optical power of the optical module.

Step (2): The management and control system performs real-time intelligent processing on the reported link quality data. The step includes at least one of the following methods:

(1) Correlation analysis is performed between the reported CRC error packet data and the received and transmitted optical power data of the optical module. For example, the number of CRC error packets increases gradually, and the received optical power of the optical module deviates from the normal range (too strong or too weak) , as shown in Figure 6, the abnormal trend of the link quality that may be caused by the optical module problem 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 increases gradually, and the received optical power of the optical module is within the normal range, it can be considered that the port has problems such as improper configuration or poor port contact, and further troubleshooting is required.
