In the present embodiment, add 12 characters behind the UDP of the described business datum head between business datum, also be consistent with the professional length of practical business transmission when guaranteeing the analog service transmission and indicate business datum, thereby can guarantee the accuracy of test result.
Shown in above-mentioned embodiment, when generating the business datum corresponding with type of service, the number n of business datum rMultiple definite mode can be arranged.
For example, suppose that the process of the terminal unit FTU generation information in the electrical power distribution automatization system is Poisson process, the distribution that FTU produces the information number is Poisson distribution.Can obtain the mathematic expectaion (weighted average) that FTU produces the information number by Poisson distribution.
Suppose that business datum is with average T mThe exponential distribution rule of time occurs, on average the every T of each FTU mProduce a metrical information second, the every T of each FTU gProduce a control information second, suppose that at last accident information seldom produces, do not affect the transmission of passage.
Based on above-mentioned hypothesis, can calculate the time interval T that FTU produces information rSuppose in a period of time T, the total information number that FTU produces is n r, the measurement business information that this total information number should equal during this period of time to produce is counted n mCount n with control information gSum, that is:
n r=n m+ n g(formula 1)
Wherein n r = T T r , n m = T T m , n g = T T g (formula 2)
Formula 2 substitution formula 1, after the arrangement:
1 T r = 1 T m + 1 T g (formula 3)
The time interval of supposing an information of FTU generation is T r, FTU produces information in time period T probability distribution is P{X=k}, obeys Poisson distribution.Learn that by Poisson distribution parameter lambda is:
λ = T T r (formula 4)
New probability formula with formula 4 generation people's Poisson distribution
P { X = k } = λ k e - λ k ! , k = 0,1,2 , . . . (formula 5)
:
P { X = k } = ( T Tr ) k e - T Tr k ! , k = 0,1,2 , . . . (formula 6)
Concept by mathematic expectaion can know, mathematic expectaion is the weighted average that all of stochastic variable X may values, therefore, try to achieve the whole cycle T to each FTU poll in main website pA central FTU produces the weighted average of information number, can calculate with mathematic expectaion:
n r = E [ k ] = Σ K = 0 ∞ kP ( k ) (formula 7)
Formula 6 substitution formula 7 are obtained:
n r = Σ k = 0 ∞ ( T P T r ) k e - T P Tr k ! (formula 8)
Like this, by FTU being produced the statistical property research of information, obtained the number n of FTU generation information rComputing formula.
Except above-mentioned formula, suppose the FTU average T rTime produces an information, and main website is T to cycle of all FTU polls of conllinear pSo,, we can also draw and calculate n rAnother formula
n r = T p T r (formula 9)
In the present embodiment, both can utilize formula 8 to obtain n r, also can utilize formula 9 to obtain n r, can select according to actual conditions.
The below is described in detail the test process of different tested types of service respectively.
Take service success rate as example.Service success rate in the present embodiment is namely in n business, the professional shared ratio of success, therefore, when test, in the tested configuration parameter except comprising: tested nodes and the tested data cell sign, also comprise tested professional frequency n and service interval t.Its overall flow is similar to flow process shown in Figure 1, is the concrete tested corresponding adjustment of type of process foundation.And, according to described tested type, analyze the data of described transmission, obtain the process of test result as shown in Figure 4, comprising:
Step S41, obtain the data of transmitting in each tested process respectively, analyze this business procedure and be successfully or failure;
Step S42, the professional number of success m of acquisition sWith service fail number of times m l
Step S43, according to service success rate η=m s/ (m s+ m l) * 100% acquisition test result.
And wherein analyze business procedure be successfully or failed process as follows:
In the data of analyzing described transmission, all include under the data message and the whole correct situations of described data message of stages in this business procedure this business success;
In analyzing the data of described transmission, all do not include in the not exclusively correct situation of the data message of stages in this business procedure or described data message this service fail.
Take operation flow shown in Figure 5 as example, finished by these a series of message switching of message 1-5 in this operation flow, if these a series of messages can both be accurately the alternately then professional success of expression, otherwise, if a certain message dropping or then service fail of other mistakes occurs wherein.Such as, total calling service needed of power distribution automation business sends total calling order by main website, after the substation is replied and is confirmed order, according to the remote signalling frame, telemetry frame, load tap changer frame, remote terminal unit status frames, the message sequence of water level frame sends to master station, and the time interval of transmission is determined by line parameter circuit value.Only finish these all actions and could calculate once professional success.
When described tested type is maximum throughput rate when test, concrete, according to the principle corresponding with described tested type, with described target service data in described tested data cell source port and destination interface between the process transmitted comprise:
Control described source port sends predetermined quantity to destination interface according to current setting speed business datum.

Step S61, obtain the business datum amount that described destination interface receives;
Whether step S62, the business datum amount that judge to receive less than predetermined quantity, if, execution in step S63 then, if not, execution in step S64 then;
Whether the business datum amount that receives has two results less than predetermined quantity, less than, perhaps equal.Can not occur greater than situation, so when the business datum amount that receives is not less than the intended service data volume, namely be that the business datum amount that described destination interface receives equates with described predetermined quantity.
Step S63, turn described current setting speed down predetermined value, control described source port and send the business datum of described predetermined quantity according to the speed of dwindling after the predetermined value, and return execution in step S61;
Step S64, determine that the transmission rate of source port is maximum throughput rate.
When described tested type is end-to-end average retardation test, according to described tested type, analyze the data of described transmission, the process that obtains test result is as follows:

Take one of them data block as example, to leave the time of source port be T to the first bit data in this data block 0, the time that last bit data arrives destination interface is T 1, the end-to-end delay that then utilizes this data block to record is T Ete=T 1-T 0
And when carrying out the test of round-trip delay, the time of last bit data arrival destination interface is T in the data block 1, destination interface can feed back an acknowledgement frame to source port, and the record source port receives that the time of acknowledgement frame is designated as T bRound-trip delay rtt c=T 1-T b

P t ( x = k ) = C n k ( βΔt ) k ( 1 - βΔt ) n - k (formula 12)
Wherein C n k = n ! k ! ( n - k ) ! ;
Formula 12 is further investigated.When n → ∞,
Figure BDA00003415243800113
The Poisson distribution of the approximate obedience of binomial distribution obtains at last:
P t ( x = k ) = e - βt ( βt ) k k ! (formula 13)
