<p>The present invention discloses a device, system and method for frame delay measurement. The frame delay measurement device includes a Delay Measurement (DM) module which is utilized for assembling and transmitting a delay measurement frame, and includes a Field Programmable Gate Array (FPGA) module which is utilized for filling a time stamp in the delay measurement frame by a current FPGA clock according to the type and entrance direction of the received delay measurement frame, wherein the DM module is also utilized for performing a single-direction or double-direction frame delay measurement by using the time stamp of the delay measurement frame. The present invention realizes a high accuracy frame delay measurement on the basis of the FPGA clock, and overcomes the defects of the dependence on an operating system clock and the poor measurement accuracy of the frame delay measurement in the prior art, so as to reflect accurately the network transmission quality between current measurement node devices.</p> |
