METHOD, DEVICE AND SYSTEM FOR DETECTING TRANSMISSION LINK

摘要

Disclosed are a method, a device and a system for detecting a transmission link. The method comprises: in each preset time period, when it is detected that a receiving terminal receives data from the transmission link to be detected, performing a cyclic redundancy check CRC on the data received; and when the CRC result is incorrect, adding a preset value to an error counting value; and when the error counting value after the addition of the preset value is not less than a preset threshold, then sending out a transmission link adjusting instruction to indicate that the transmission link to be detected needs to be adjusted. The solution can monitor the quality of the transmission link in real time, and thereby can promptly discover a failure in the transmission link and solve the failure in time, which ensures the stability of the transmission link.
