Method, device and data transmission network for changing bit error alarm threshold online

Abstract

The invention discloses a method and device for changing an error code warning threshold in an on-line manner, and a data transmission network. The method comprises the following steps that an error code expected warning threshold of a link is set, virtual error codes are inserted in data streams transmitted by the link, and error codes which satisfy the requirements of the error code expected warning threshold in the link are added to the virtual error codes, such that an error code actual warning threshold can be obtained; and the transmission error code rate of the link is calculated, and when the transmission error code rate of the link exceeds the error code actual warning threshold, a warning message is transmitted. With the method and device for dynamically changing the error code warning threshold in an on-line manner of the invention adopted, the error code warning threshold of a specified link can be dynamically changed according to requirements without a large quantity of complex warning threshold adjustment work for all network elements on a whole transmission link required, and in a testing process, normal transmission of services loaded by the transmission link will not be affected, and extra influence on the services will not be brought about, and therefore, network operation and maintenance cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method, a device and a data transmission network for changing a code error alarm threshold online. Background technique [0002] In the transmission network, due to various reasons such as external interference, electromagnetic interference, equipment grounding, ambient temperature, ambient temperature is too high or too low, power is too high or too low, transmission medium characteristics, etc., the quality of the transmitted information will be damaged. , it is manifested that some bits of the digital stream have errors after receiving the judgment, and these errors are called bit errors. [0003] In the actual network, due to various conditions, bit errors cannot be completely eliminated, but under normal circumstances, a small amount of bit errors in a short period of time will not have a major impact on the business, only those that persist Only when a large nu...

AI Technical Summary

Problems solved by technology

If the alarm threshold is modified for the entire network, it will be time-consuming and laborious, and many accidents may occur during the adjustment process; if only part of the modification is made, it will be difficult in resource management and O&M management, and it is easy to cause inconsistent link alarms, and also Unnecessary problems will be caused to affect fault location and troubleshooting

[0011] In summary, although the existing bit error alarm thresholds cannot fully meet the needs of various services, considering the limitations and cost of modifying the thresholds, domestic and foreign operators have no plans or plans to comprehensively modify the bit error alarm thresholds
