Abstract
Embodiments of the present invention provide a delay measurement method and device. The method includes: determining a first delay of a first path; obtaining a first two-way delay of a first two-way path; obtaining a first one-way delay from a third IGW port to a provider/provider edge device; obtaining a second one-way delay from the provider/provider edge device to a first IGW port; determining a second delay, where the second delay is obtained by subtracting the first one-way delay and the second one-way delay from the first two-way delay; and comparing the first delay with the second delay. By means of the foregoing solutions, a one-way delay relationship between delays from the OTT server to different IGWs may be effectively determined, so as to determine a path whose one-way delay is optimal according to the one-way delay relationship.
