Method, apparatus, and system for implementing delay measurement
A method and an apparatus for implementing delay measurement. The method includes: determining, by a measurement apparatus, a delay T0 generated when a first packet is transmitted at a first priority over a first loopback path that includes a first sub-path and a second sub-path; determining a delay T1 generated when a second packet is transmitted over a second loopback path that includes the first sub-path, the second sub-path, a third sub-path, and a fourth sub-path, where the second packet is transmitted at the first priority over the first sub-path and the second sub-path and is transmitted at a second priority over the third sub-path and the fourth sub-path; and determining a delay according to T0 and T1. Therefore a delay can be measured only by implementing a measurement function in the measurement apparatus, thereby resolving a problem of complex implementation.
