Abstract

Embodiments of the present invention provide a method and device for measuring delay. The method includes: the method includes: determining the first delay of the first path; acquiring the first two-way delay of the first bidirectional path; acquiring the third IGW port to The first one-way delay of the provider / provider edge device; obtain the second one-way delay from the provider / provider edge device to the first IGW port; determine the second delay, and the second delay Subtracting the first one-way delay and the second one-way delay from the first two-way delay; comparing the first delay with the second delay, and determining the distance from the OTT server to the second IGW port The relationship between the one-way delay of the path and the one-way delay of the path from the OTT server to the third IGW port. The above solution can effectively determine the one-way magnitude relationship between the OTT and different IGWs, so as to determine the path with the best one-way time delay according to the one-way magnitude relationship.

Description

technical field [0001] Embodiments of the present invention relate to the field of information technology, and more specifically, to a method and device for measuring time delay. Background technique [0002] With the Internet protocol (English: Internet Protocol, referred to as: IP) of the entire network, operators need to measure the delay of each Internet Gateway (Internet Gateway, referred to as: IGW) egress, and select the optimal path according to the measurement results, so as to provide provide better service to users. [0003] The delay measurement methods in the prior art include one-way measurement and two-way measurement. If one-way measurement is performed on node A and node B, the one-way delay from node A to node B may be measured, and the one-way delay from node B to node A may also be measured. If a two-way service strategy is implemented for node A and node B, the time delay from node A to node B and then to node A, or the time delay from node B to node A...
