The invention cans solve the problem of background technique, which can change the test parameter, based on the result of active measurement, to obtain the useful bandwidth of network.
Description
One, technical field
The present invention relates to the IP network communication technical field, relate in particular to a kind of method of gathering the IP network performance by active type measure.
Two, background technology
Current internet has carried increasing important application, and network configuration is also complicated day by day.Measurement to the IP network performance is whole network behavior feature to be understood, analyzed in depth the important means of finding network performance bottleneck, the configuration of optimization Internet resources, strengthening network management, lifting network performance.
Mode to the IP network performance measurement mainly contains two kinds at present: initiatively measure and passive measurement.
Initiatively measuring is the test of finishing by the applied in network performance test instrument, and initiatively the result who measures generally comprises: throughput, response time, shake, IP packet transfer latency, IP packet loss rate etc.Its testing procedure is as follows: 1, test parameter is set, as tested end points, with reference to end points, transmission rate, test pack size, test use agreement type etc.; 2, start test, according to the test parameter that is provided with in the step 1, in network, inject the packet testing characteristics of network by the applied in network performance test instrument.Owing to initiatively measure is to inject test pack to come the test network characteristic in network, during test, a reference node need be set in network, by node of applied in network performance test instrument test network to IP network performance with reference to the network link the end points, therefore its advantage is that controllability to measuring process is than higher, flexibly, motor-driven, be easy to carry out IP network performance measurement end to end; But its shortcoming is also very obvious: the measurement flow of injection can change the ruuning situation of network itself, makes result and the actual conditions measured have deviation, and the measurement flow also can increase network burden.
Three, summary of the invention
The present invention measures the above-mentioned technical problem that exists for the active that solves in the background technology, and a kind of acquisition method of IP network performance is provided.Can be according to the active measurement result of front, the test parameter that uses when measuring, thereby the available bandwidth of Measurement Network accurately by changing.
Technical solution of the present invention is: the present invention is a kind of method by active type measure collection IP network performance, and its special character is: this method may further comprise the steps successively:
1) uses the initial testing parameter, initiate initiatively to measure, and collect its measurement result;
2) increase or reduce test parameter, initiate initiatively to measure for the second time, and collect its measurement result;
3) regulate test parameter according to twice active measurement result, initiate once more initiatively to measure, and collect its measurement result;
4) repeating step 3), stop to measure up to the user.
Above-mentioned steps 3) in, when regulating test parameter, if IP packet transfer latency in the measurement result or IP packet loss rate, response time, shake when last time, measurement result increased, then reduce test parameter; If IP packet transfer latency or IP packet loss rate, response time, shake remain unchanged or reduce, then increase test parameter.
Above-mentioned test parameter is transmission rate or test pack size.
Utilize when initiatively metering system is measured, can take a part of network bandwidth, what of its occupied bandwidth can be regulated by regulating test parameter, can improve and initiatively measure the network bandwidth that takies as increasing transmission rate.Article one, the IP network performance of link is stable in the short relatively time, owing to initiatively measure when measuring and to take a part of bandwidth, after initiatively measuring the bandwidth increase that takies, still be less than or equal to available bandwidth, so initiatively measurement result of measuring such as response time, IP packet loss rate, IP packet transfer latency, shake etc. can remain unchanged.On the contrary, after initiatively measuring the bandwidth increase that takies, greater than available bandwidth, measurement result such as response time, IP packet loss rate, IP packet transfer latency, shake etc. can increase so, error occurs.And will initiatively measure the very little value of bandwidth settings that takies, then its measurement result remains unchanged, but available bandwidth that can not Measurement Network.Therefore the present invention utilizes above principle, carries out earlier twice successively and initiatively measures, and dynamically changes test parameter according to measurement result then, can alleviate owing to initiatively measure the network burden that when test, increases, thus the available bandwidth of Measurement Network accurately.
Four, description of drawings
Fig. 1 is the design sketch that active of the present invention is measured.
Five, embodiment
Concrete grammar of the present invention is as follows:
1) uses the initial testing parameter, initiate initiatively to measure, and collect its measurement result;
2) increase or reduce test parameter, initiate initiatively to measure for the second time, and collect its measurement result;
3) regulate test parameter according to twice active measurement result, initiate once more initiatively to measure, and collect its measurement result;
4) repeating step 3), stop to measure up to the user.
In step 3), if the IP packet transfer latency in the measurement result (or IP packet loss rate, response time, shake etc.) than last time measurement result increase shared bandwidth when then reducing test parameter (as transmission rate) and initiatively measuring to some extent to reduce.If IP packet transfer latency (or IP packet loss rate, response time, shake etc.) remains unchanged or reduces, shared bandwidth when then continuing to increase test parameter and initiatively measuring to improve.
The ratio that increases or reduce test parameter can be set in advance according to actual conditions.
Owing to dynamically change test parameter according to preceding twice measurement result, can alleviate owing to initiatively measure the network burden that when test, increases, thus the available bandwidth of Measurement Network accurately.
Fig. 1 has shown the effect of the available bandwidth that utilizes method Measurement Network of the present invention, when beginning to test, used a test parameter at random, after test finishes, increase transmission rate, initiate test for the second time, after test finishes for the second time, by the compare test result, can find that the bandwidth that test takies has risen, and shake, network performance parameters such as response time have also risen, so reduce transmission rate, initiate test for the third time, for the third time behind the EOT, for the third time test result and secondary test result are compared, can find that the bandwidth that test takies descends, simultaneously, shake, response time also descends to some extent, so the increase transmission rate is carried out the 4th test, the rest may be inferred.Curve 1 is represented the available bandwidth of the reality of network among Fig. 1, and curve 2 is exactly according to above-mentioned method of testing and measured throughput, the i.e. figure of the test value of available bandwidth.As can be seen, the present invention's method of using broken-line type constantly to approach is similar to the actual available bandwidth value that obtains network.
Explanation of nouns:
1, IP packet loss rate: be meant IP bag number of losing when between two reference points, transmitting and the total ratio of IP bag that has sent.
2, IP packet transfer latency: IP packet transfer latency is defined as and passes one or more network segments, transmits the time (not considering to transmit success or not) that the IP bag is experienced.
3, throughput: be meant in the unit interval successfully data packet number by network node.
4, the response time: refer to that sending one from a network node asks to receive the time that response is required.
5, shake: in one section short measuring intervals of TIME, the difference of maximum IP packet transfer latency and minimum IP packet transfer latency.
6, available bandwidth: be meant at network path (path) to exist under the situation of background traffic, can offer certain professional maximum throughput.
