QoS (Quality of Service, service quality) is the key factor that can Network achieve success, and the qos parameter that influences customer service experience generally includes time delay, delay variation, packet loss etc.Along with network technology and rapid development of multimedia services, the user unprecedentedly increases network resources demand, and network also becomes and becomes increasingly complex, and network performance is more unpredictable and uncontrollable.In order to carry out network performance management effectively, to improve service provider's service quality, need measure network performance, thereby find network bottleneck, in advance it is optimized configuration, thereby improves user's experience.
End-to-end time delay shake in the network performance index is meant that transmitting terminal is transferred in the data flow of receiving terminal (Stream), the variation of the propagation delay time of different grouping data, and it is one of critical network performance index that influence customer service experience.For example, at IP (Internet Protocol, Internet protocol) voice signal that transmits in the network at transmitting terminal after overcompression packing, because the path that packet transmits may be different, therefore different packets arrives time of receiving terminal also may be different, cause receiving terminal to produce off and on situation when voice playback, promptly produce voice jitter, when the voice jitter situation is serious, can make the user be difficult to accept.
If can measure, grasp the situation of network delay shake in advance, the technical staff just can take some to eliminate the method for shake according to the network delay jitter conditions of grasping, receive the influence that buffering area is eliminated the delay variation generation such as increasing, thereby improve user's experience at receiving terminal.
All be on the basis of having measured network delay generally in the prior art at present, determine the network delay shake according to the network delay of repeatedly measuring.Particularly, the network delay of measuring subtracted each other obtain delay inequality, the changing value of network delay just is according to the changing value statistics network delay variation of network delay.For example, the end-to-end network delay that a plurality of moment measure is respectively T1, T2, T3, T4, T5......, calculates the difference of these time delays: d1=T2-T1; D2=T3-T2; D3=T4-T3; D4=T5-T4......, according to difference (changing value of network delay just) the computing network delay variation that calculates.Concrete, can average or maximum or minimum value or calculate mean-square value etc. and shake to d1, d2, d3, d4, d5...... as end-to-end network delay.
And time-delay needs to adopt external clock system (as GPS) local clock synchronously when Measurement Network, and in the process of synchronous local clock, survey crew need be at the outdoor reception antenna that sets up, and antenna linked to each other with measuring terminals, thereby communicate by antenna and GPS, the local clock of synchro measure terminal, so more complicated and loaded down with trivial details.If not adopting the external clock synchro system carries out synchronously the two ends local clock, delay time when the transmitting time of the transmitting terminal that the message that transmits between by two-end-point carries and the time of reception of receiving terminal come Measurement Network, then can introduce the network delay error because transmitting terminal is asynchronous with the receiving terminal clock.
In sum, the network delay measurement Technology Need of prior art is measured after adopting the first local clock to the network two ends of external clock synchro system to carry out synchronously again, does not also have special measurement means to measure at the delay variation of network.

Embodiment
Transmitting time and the time difference of the time of reception variation of determining network delay measured message between of the embodiment of the invention by measured message repeatedly determined the end-to-end network delay shake thereby change according to the network delay of statistics.
The embodiment of the invention one is for determining the method that end-to-end network delay is shaken by the transmitting time of twice measured message and the time difference of time of reception; Embodiment two is for repeatedly the transmitting time of measured message and the time difference of time of reception are determined the method that end-to-end network delay is shaken.
Embodiment one
The embodiment of the invention is that example illustrates technical scheme with terminal A in the Measurement Network system to the delay variation of terminal B.As shown in Figure 1a, be the schematic diagram of embodiment of the invention measurement terminals A to the terminal B delay variation.Concrete end-to-end network delay jitter measurement method, flow chart comprise following concrete steps shown in Fig. 1 b:
Step S101: terminal A sends to terminal B and carries the probe messages A that surveys sign, and adds transmitting time R1 in message A.
Surveying sign is the message that is used for the Measurement Network delay variation in order to indicate this message.
Step S102: after terminal B receives message A, the local zone time S1 of terminal B during this message of recorder, and from message A, obtain time R1.
Terminal B is the message that is used for the Measurement Network delay variation according to this message of detection identity validation among the message A, the local zone time S1 of terminal B during this message of recorder.
Step S103: terminal A sends to terminal B and carries the probe messages B that surveys sign, and adds local transmitting time R2 in message A.
Step S104: after terminal B receives message B, the local zone time S2 of terminal B during this message of recorder, and from message B, obtain time R2.
Terminal B is the message that is used for the Measurement Network delay variation according to this message of detection identity validation among the message B, the local zone time S2 of terminal B during this message of recorder.
Step S105:, determine the network delay shake according to time R1, R2, S1, S2.
Concrete, can adopt formula 1 or formula 2 to calculate and send network delay shake J between probe messages A and the message B:
J＝(R2-S2)-(R1-S1) (1)
J＝(R1-S1)-(R2-S2) (2)
Explain formula 1 herein:
Network delay when supposing T1 for transmission probe messages A, Δ t are the clock jitter of the local clock of the local clock of terminal A and terminal B, and formula (3) is then arranged
(R1-S1)＝T1+Δt (3)
That is to say network delay and two ends clock jitter when the transmitting time of probe messages A and the difference of time of reception comprise transmission probe messages A.
Network delay when supposing T2 for transmission probe messages B, Δ t are the time deviation of the local clock of the local clock of terminal A and terminal B, and formula (4) is then arranged
(R2-S2)＝T2+Δt (4)
That is to say the network delay the when transmitting time of probe messages B and the difference of time of reception comprise transmission probe messages B and the deviation of two ends local clock.
Because the deviation of two ends local clock is fixed, so formula 3 equates with Δ t in the formula 4.
The network delay difference of transmitting between i probe messages and i-1 the probe messages of transmission should be T2-T1, perhaps T1-T2.
Though directly do not obtain T1 and T2 in the embodiment of the invention, deduct formula 4 backs with formula 3 and just can obtain the poor of T1 and T2, as shown in Equation 5:
T2-T1＝(R2-S2)-(R1-S1) (5)
So, network transfer delay difference J=(R2-S2)-(R1-S1).
Based on above-mentioned same reasons, also can be according to formula 2 computing network delay variations.
The embodiment of the invention provides a kind of end-to-end network delay jitter measuring, as shown in Figure 2, comprising: receiver module 201, extraction module 202, delay variation determination module 203.
Receiver module 201, be used to control terminal B and receive probe messages A and the message B that terminal A sends, according to detection identity validation message A in the message and message B is the message that is used for the Measurement Network delay variation, the local zone time S1 of terminal B during recorder message A, the local zone time S2 of terminal B when receiving message B; And probe messages A and message B sent to extraction module 202.
Extraction module 202 is used for the local zone time R1 of terminal A when probe messages A extracts this message of transmission that this message carries, the local zone time R2 of terminal A when probe messages B extracts this message of transmission that this message carries.
Delay variation determination module 203 is used for determining the network delay shake of terminal A to terminal B according to S1, the S2 of receiver module 201 records and R1, the R2 of extraction module 202 acquisitions.
The embodiment of the invention is owing to determine the shake of network delay by measuring successively transmission, the time of reception of twice message, thereby saved the step of definite network delay, simplified the process that end-to-end time delay is shaken of measuring.

I-1
Step S302: the local zone time of terminal B during each probe messages of terminal B recorder, and from each probe messages, obtain the transmitting time of this message.
Terminal B confirms that this message is the message that is used for the Measurement Network delay variation, the local zone time of terminal B during this probe messages of recorder according to the detection sign of each probe messages.
For example, for i probe messages, the local reception time of terminal B record is R
i, and from this message, obtain time S
iFor i-1 probe messages, the local reception time of terminal B record is R
I-1, and from this message, obtain time S
I-1
Step S303: from all probe messages, select at least one pair of probe messages,, determine this network transfer delay difference to probe messages according to this transmitting time and time of reception to each probe messages in the probe messages.
For example, S

Wherein, described i, j are natural number.
From each probe messages, repeatedly select two probe messages, obtain a plurality of network transfer delay differences.Determine the network delay shake according to these network transfer delay differences.
More excellent scheme be access time two adjacent probe messages determine the network transfer delay difference of two probe messages, thereby obtain the network transfer delay difference of two adjacent probe messages of a series of times.Concrete, as to receive for a terminal B probe messages, i probe messages for example is if exist adjacent probe messages---i-1 the probe messages in preceding transmission (or reception) of time, according to the transmitting time S of this probe messages
i, time of reception R
iAnd the transmitting time S of i-1 probe messages
