Description

Technical Field

[0001] The present invention belongs to the field of computer networks, and particularly relates to a method for monitoring and warning the quality of an optical link and its application in a computing network cluster. Background Art

[0002] When a computing network cluster works, it is necessary to monitor the quality of the optical link. The usual monitoring method is to first monitor the network status of the computing network cluster, and then check the status of the optical link when an abnormality occurs in the network, and then perform corresponding processing according to the problems that occur in the optical link.

[0003] The above monitoring method has the following defects: 1. Only when an abnormality occurs in the network can the problems of the optical link be discovered and processed, and faults cannot be discovered and processed in time; 2. Network abnormalities will affect the normal operation of the computing network cluster, reducing the reliability and stability of the computing network cluster; 3. The real-time quality of the optical link in the network cannot be monitored, and there is a risk of sudden abnormalities in the network link. Summary of the Invention

[0026] Figure 1 The flowchart of the method for monitoring and warning the quality of the optical link according to the embodiment of the present invention is shown. Refer to Figure 1 , and the method for monitoring and warning the quality of the optical link includes the following steps:

[0027] S1. Build a cloud management platform and configure the address of the cloud management platform.

[0028] Specifically, first connect devices such as optical modules, optical fibers, switches, network cards, servers, etc. to complete networking and build the network environment of the computing network cluster. Then build a cloud management platform on the server and configure the address of the cloud management platform on the switch.

[0029] S2. Set optical module registers inside each optical module.

[0030] Specifically, in order to improve the efficiency of data processing and operation, the optical module register is a private register.

[0031] S3. Each optical module collects the status data of the optical link in real time at a first time interval and stores the status data of the optical link in the optical module register.

[0032] Specifically, the status data of the optical link includes: optical signal-to-noise ratio, bit error rate (BER), etc.

[0033] Further, the bit error rate is usually expressed in scientific notation, i.e., n×10 -x , where n represents the digital part, 1≤n<10, x represents the exponential part, 1≤x≤15 and x is a natural number. To optimize the data storage space, data transmission time and play an encryption role, the bit error rate is stored in a specific data format, and only the numerical values of n and x are stored in the specific data format.

[0034] S4. The switch collects the status data of the optical link in the optical module register at a second time interval, and sends the status data of the optical link to the cloud management platform according to the address of the cloud management platform.

[0035] S5. The cloud management platform analyzes the status data of the optical link at a third time interval, determines the optical links with poor link status, and sends a link quality warning notice to the optical modules corresponding to the optical links with poor link status.

[0036] Specifically, determining the optical links with poor link status includes: comparing the bit error rate in the status data of the optical link with the pre-correction bit error rate. If the bit error rate is not less than the pre-correction bit error rate, the corresponding optical link is determined as the optical link with poor link status.

[0037] Further, after a large number of practices, the inventor sets the pre-correction bit error rate to 1×10 -6 .

[0038] Specifically, the first time interval is set to a microsecond-level time interval.

[0039] Specifically, the setting of the second time interval needs to consider the performance of the switch. An overly short time interval, i.e., a high sampling frequency, will cause the switch CPU to be overly occupied. In addition, the practical application value of the second time interval also needs to be considered. Usually, after a fault in the optical link is identified, it relies on manual processing, which generally takes more than ten minutes to dozens of minutes to complete. Therefore, the second time interval does not need to reach the millisecond level, and only a few seconds to dozens of seconds are required. Therefore, the second time interval is set to a second-level time interval.

[0040] Specifically, the cloud management platform performs data analysis after receiving the status data of the optical link. Therefore, the third time interval also only needs a few seconds to dozens of seconds, and the third time interval is set to a second-level time interval.

[0041] In summary, for the optical link quality monitoring and warning method provided by the present invention, each optical module collects the status data of the optical link in real time at a first time interval and stores it in the optical module register; the switch collects the status data of the optical link in the optical module register at a second time interval and sends it to the cloud management platform; the cloud management platform analyzes the status data of the optical link at a third time interval, determines the optical links with poor link status, and issues a link quality warning notice to the optical modules corresponding to the optical links with poor link status. The optical link quality monitoring and warning method can monitor the quality status of the optical link in real time and automatically in a large-scale computing network cluster, issue a warning before the link quality of the optical link drops to a threshold, causing link oscillation and further leading to network failures, enabling the operation and maintenance personnel to replace the relevant hardware of the faulty optical link in the idle state of the computing network cluster operation, minimizing the impact of the optical link failure on the entire network to the greatest extent, saving the human operation and maintenance cost, and improving the stability and reliability of the network.

[0042] The present invention also provides an application of the foregoing optical link quality monitoring and warning method in a computing network cluster.
