Document Type and Number:
WIPO Patent Application WO/2016/150021
Kind Code:
A1
Abstract:
Provided are a packet forwarding delay measurement method, device and system. The packet forwarding delay measurement method comprises: obtaining a time difference between a sending end sending a measurement packet to a receiving end and receiving a measurement response packet fed back by the receiving end, obtaining a processing time for the receiving end with regard to the measurement packet, and obtaining a time deviation between at least two modules in at least one end within the two ends of the sending end and the receiving end, said modules processing the packet; calculating a packet forwarding delay between the sending end and the receiving end according to the time difference, the processing time and the time deviation. The present invention solves the problem in the prior art that with regard to a packet forwarding delay between two ends, delay calculation is not accurate due to times not being synchronised, and a time deviation between modules produced by there being a plurality of modules processing a packet on at least one end. The present invention increases the accuracy of calculating the delay between the sending end and the receiving end.
