The preferred embodiment of the present invention, using the first equipment as server, the second equipment is illustrates for client, this hair
Bright preferred embodiment provides a kind of test method of client-server uplink and downlink delay, and this method includes：
Step 1, timing differential analyze, select a network delay it is low (such as network delay be less than 10ms, below all with
10ms is example), the environment of network stabilization.Client is constantly to server transmission data packet, after server receives data packet
Data packet is also beamed back immediately, and Fig. 3 is the data transmission procedure provided according to the preferred embodiment of the present invention and timestamp record signal
Figure.As shown in figure 3, it, which is labelled with when data packet sends and receives, needs the timestamp recorded.
(1) network delay testing mechanism：
The round-trip round-trip delay of n-th：
T=(tcrn-tcsn)-(tssn-tsrn)
When less than 10ms to be then considered as network delay relatively low by T.
(2) server and client clock variance analysis (being equivalent to the step S202 in above-described embodiment)
Timing differential analysis carries out 2M round-trip, time-consuming H, wherein
H=tcr2M-tcs1；
Because T is smaller, it is therefore assumed that uplink and downlink delay is equal under this environment, it is equal to T/2；
Such as using client time as reference time, if timing differential (be equivalent on of the server end relative to client
State the timing differential in embodiment) it is Δ t；
It is then round-trip for n-th：
It can be obtained in conjunction with above formula：
It is summed again according to latter M times of 2M round-trip data round-trip data divided by M takes mean value, then
Therefore server end is relative to the timing differential Δ t of client：
M round-trip timing differential data before being subtracted according to rear M round-trip timing differential data in 2M round-trip data
Again divided by approximate time interval H/2 obtains timing differential pace of change, thus clock difference of the server end relative to client
Different pace of change Δ v is：
Record the client time point t of Δ t and the completion of Δ v and variance analysiscptIt (is equivalent in above-described embodiment
tcpt)；
Step 2, on the spot network data acquisition
To test target environment, constantly to server transmission data packet, server receives after data packet immediately client
Also data packet is beamed back；Execute K back and forth；The whole client time stamps of record and server timestamp
Step 3, data calculate
Timing differential Δ t of the server relative to client when timing differential analysis is completed；
The timing differential etc. to the server before test data transmission relative to client when completing is analyzed from timing differential
Time interval before being sent to test data when timing differential analyzes completion is multiplied by timing differential pace of change：(tcsi-tcpt)
×Δv
Therefore the server in test is relative to the timing differential of client
Δt+(tcsi-tcpt)×Δv
Therefore each (range of i is from 1 to K) round-trip upstream time can be expressed as：
tsri-[tcsi+Δt+(tcsi-tcpt)×Δv]
Each (range of j is from 1 to K) round-trip downgoing time can be expressed as：
[tcrj+Δt+(tcrj-tcpt)×Δv]-tssj
