But the network delay is not symmetrical, for example, the round-trip delay time from device A to device B is 400 milliseconds
Then the default delay time from device A to device B is 200 milliseconds, and the delay time from device B to device A is 400 milliseconds, which is actually wrong; moreover, in some scenarios (such as: predicting the arrival of network retransmission data Time scenario), it is necessary to know the accurate one-way delay time, but the commonly used network delay estimation method cannot obtain accurate one-way delay time

Embodiment 1

[0035] see figure 1As shown in the flow chart of a method for determining a one-way network delay, this embodiment proposes a method for determining a one-way network delay, including the following specific steps:

[0036] Step 100, the detection node obtains the first local NTP time of the detection node itself.

[0037] In the above step 100, when the detection node starts up, it will obtain the first local NTP time of the detection node itself, so as to adjust the NTP time of the detection node itself.

[0038] The first local NTP time is the current NTP time on the NTP client installed on the detection node.

[0039] Step 102: Generate a time synchronization request by using the first local NTP time stored by the detection node itself, and send the generated time synchronization request to each of the at least two NTP servers respectively.

[0040] In the above step 102, in order to send the generated time synchronization request to each of the at least two NTP servers r...

Abstract

The invention provides a one-way network delay determination method, device and electronic equipment, which can accurately adjust the local NTP time of the detection node itself before sending the detection data packet for detecting network delay, and use the precisely adjusted The detection packet generated by the local NTP time is sent to the detected node, so as to detect the one-way network delay between the detection node and the detected node on the basis of the precisely adjusted local NTP time, so as to ensure the detection Accuracy of the obtained one-way network delay between the detecting node and the detected node.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and electronic equipment for determining one-way network delay. Background technique [0002] At present, the network delay estimation method commonly used in the Internet uses the round-trip delay time to judge the data transmission delay time between two network terminals. But the network delay is not symmetrical, for example, the round-trip delay time from device A to device B is 400 milliseconds. Then the default delay time from device A to device B is 200 milliseconds, and the delay time from device B to device A is 400 milliseconds, which is actually wrong; moreover, in some scenarios (such as: predicting the arrival of network retransmission data Time scenarios), it is necessary to know the accurate one-way delay time, but the commonly used network delay estimation methods cannot obtain accurate one-way delay time.
