Abstract

The invention discloses a device and a method for measuring frame error rate in a transmission link, which belong to communication technologies. The device comprises a data sending end processing part and a data receiving end processing part which are mutually connected, wherein the data sending end processing part persistently generates maintenance frames and inserts the maintenance frames in the transmission link, and the maintenance frames carry sent total frame information when the data sending end inserts the maintenance frames; the data receiving end processing part respectively reads the total frame information which represents start and end positions of a measuring period and is carried by the maintenance frames when the frame error rate needs to be measured, counts the number of frames correctly received by the data receiving end in the measuring period and calculates the frame error rate. The invention avoids the loss of service interruption caused by measurement, cannot cause counting deviation and has high reliability.

Description

technical field [0001] The present invention relates to communication technology, and more particularly to a device and method for measuring frame error rate in a transmission link. Background technique [0002] In a communication system, after the data network is built, the error performance of the transmission link needs to be tested for acceptance and service activation. At the same time, in the daily system maintenance, it is even more necessary to test the status of the transmission link. Among them, corresponding to the transmission based on the packet data transmission mode, an important indicator for detecting the condition of the transmission link is the frame error rate. [0003] The frame error rate refers to the ratio of the total number of frames that cannot be received correctly due to data damage in the transmission link to the total number of data frames sent at the sending end within a period of time. Usually, in an ideal transmission link, 100% of the data...
