Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.

The embodiment of the invention discloses a kind of power system broadband network performance test methods, the method is applied to power system, including: business datum definition phase and test phase.

The business datum definition phase is that whole test process carries out at initial operating stage, and in the present embodiment, this process is specially according to power business specification, utilizes program language to describe the message format of data of each business, message field (MFLD) and sequential etc..Thus different business is made a distinction, in order to follow-up when testing, it is possible to what clearly carry out according to these features testing is the data of any business.

The business datum definition phase is only when first time tests, or just performs when there being new definition rule to produce.

Test phase is then that test process is required for the stage of experience each time, and its flow process is as it is shown in figure 1, include:

Step S11, reception test request, described test request includes: tested type of service mark, tested type identification and tested configuration parameter, at least includes in described tested configuration parameter: tested nodes and tested data cell mark；

Main frame or processor in power system perform the method.First the test request of tester's input is received, test request includes the mark of tested type of service, the mark of tested type and tested configuration parameter, mark and being designated of tested type of tested type of service preset, can be and type of service or tested type letter or character one to one, when receiving this character, namely can determine that it is that any business is carried out any test.Certainly, this mark can also be the title of concrete type of service or test-types.

Tested configuration parameter sets the number needing the node for participating in test process, and determines to be specially which data cell by measured data unit marks.

Step S12, according to described tested type of service, tested type and tested configuration parameter, configure in described power system and identify corresponding data cell with described tested data cell；

This process is for determining that the type of business datum, nodes, data cell identify.Such as 20 management of power load service nodes of substation simulation, then need to configure the IP address port of the IP address of each node and port and master station, by main website selection to information such as those class service message data of which node transmission management of power load after being connected with main website, so that power system can carry out whole test process.

The parameters such as further, tested configuration parameter can also include: tested business number of times and service interval, then need configuration transaction dry run number of times, the interval of each service analogue.

Step S13, generate the business datum corresponding with described tested type of service according to message format corresponding to tested type of service set in advance and described, message field (MFLD) definition and message sequential；

Identify according to the tested type of service in step S11, it is determined that tested type of service, and generate the business datum of this type of service according to the predefined message format corresponding with this type of service, message field (MFLD) definition and message sequential.

Step S14, described business datum is converted to target service data according to preset rules, including at least having described business datum and identifying the information of type of service of described business datum in described target service data；

In target service data, there is the information of the type identifying the business datum comprised in these target service data, consequently facilitating identification is the data of any type of service.

Step S15, according to the principle corresponding with described tested type, will be transmitted between described target service data source port in described tested data cell and destination interface；

According to different test-types, set concrete data transmission principle.Such as, when described tested type is maximum throughput rate test, then needs to set source port and send speed and the quantity of business datum.

Step S16, according to described tested type, analyze the data of described transmission, obtain test result.

In power system broadband network performance test methods disclosed in the present embodiment, the business datum of different-format is generated according to different types of service, and the data transmission procedure of analog service, test, thus solving in prior art, the problem that data stream is single, for realizing the power business bearing capacity of network is tested and assessment establishes basis, meets the diversity requirements of power business.

In another power system broadband network performance test methods disclosed in the embodiment of the present invention, its basic procedure is identical with flow process shown in Fig. 1, the business datum corresponding with described tested service identification is converted to the detailed process of target service data according to preset rules as in figure 2 it is shown, include by it:

Step S21, described business datum utilize udp protocol form be indicated；

Step S22, after the UDP head of described business datum between business datum add 12 bytes；

The purpose herein adding 12 bytes is in that, utilizes udp protocol simulation Transmission Control Protocol, and its length is consistent with Transmission Control Protocol data length.

Step S23, in described 12 bytes, choose predetermined number byte, the type of service of business datum described in preset rules labelling.

The present embodiment is selected one of them byte, adds type of service mark.

In addition, described target service data also include:

Business datum length information, check information, traffic sequence number, business confirm serial number and retransmit mark.

Concrete business datum form, as shown in Figure 3,12 supplementary bytes mainly include 1 byte type of service identifier, 1 byte business datum length, 2 byte check bit, 2 byte traffic sequence number, 2 byte industry confirmation business serial number, 2 byte markers and the identification byte of 2 bytes.Wherein inside 2 identification bytes, comprise 1 request connection identifier, 1 retransmit mark, 1 confirm mark, 1 terminate mark, reserve for remaining 12.

In the present embodiment, after the UDP head of described business datum, between business datum, add 12 characters, it is ensured that also keep consistent and mark business datum during analog service transmission with the business length of practical business transmission, thereby may be ensured that the accuracy of test result.

As shown in above-described embodiment, when generating the business datum corresponding with type of service, the number n of business datum_rCan have and multiple determine mode.

For example it is assumed that the process that the terminal unit FTU in electrical power distribution automatization system produces information is Poisson process, it is Poisson distribution that FTU produces the distribution of information number.FTU can be obtained by Poisson distribution and produce the mathematic expectaion (weighted mean) of information number.

Assume that business datum is with average T_mThe exponential rule of time occurs, the average every T of each FTU_mSecond produce a metrical information, the every T of each FTU_gSecond produce one control information, finally suppose accident information seldom produce, do not affect the transmission of passage.

Based on above-mentioned it is assumed that FTU can be calculated produce the interval T of information_r.Assuming in a period of time T, the total information number that FTU produces is n_r, this total information number should be equal to the measurement business information number n during this period of time produced_mWith control Information Number n_gSum, it may be assumed that

n_r=n_m+n_g(formula 1)

Wherein $n_r=\frac{T}{T_r},n_m=\frac{T}{T_m},n_g=\frac{T}{T_g}$ (formula 2)

Formula 2 substitutes into formula 1, after arrangement:

$\frac{1}{T_r}=\frac{1}{T_m}+\frac{1}{T_g}$ (formula 3)

Assuming that the interval that FTU produces an information is T_r, it is P{X=k} that FTU produces the probability distribution of information in time period T, obeys Poisson distribution.Learnt that parameter lambda is by Poisson distribution:

$\mathrm{\λ}=\frac{T}{T_r}$ (formula 4)

New probability formula by formula 4 generation people Poisson distribution

$P\{X=k\}=\frac{{\mathrm{\λ}}^k{e}^{-\mathrm{\λ}}}{k!},k=\mathrm{0,1,2},...$ (formula 5)

:

$P\{X=k\}=\frac{{\left(\frac{T}{\mathrm{Tr}}\right)}^k{e}^{-\frac{T}{\mathrm{Tr}}}}{k!},k=\mathrm{0,1,2},...$ (formula 6)

By the concept of mathematic expectaion it is recognised that mathematic expectaion is all of stochastic variable X is likely to the weighted average of values, it is therefore desirable to must in main website whole cycle T to each FTU poll_pThe weighted mean of central produced an information number of FTU, it is possible to calculate by mathematic expectaion:

$n_r=E\left[k\right]=\underset{K=0}{\overset{\∞}{\mathrm{\Σ}}}\mathrm{kP}\left(k\right)$ (formula 7)

Formula 6 is substituted into formula 7 obtain:

$n_r=\underset{k=0}{\overset{\∞}{\mathrm{\Σ}}}\frac{{\left(\frac{T_P}{T_r}\right)}^k{e}^{-\frac{T_P}{\mathrm{Tr}}}}{k!}$ (formula 8)

So, by FTU being produced the statistical property research of information, obtaining FTU and producing the number n of information_rComputing formula.

Except above-mentioned formula, it is assumed that the average T of FTU_rTime produces an information, and cycle of all FTU polls of conllinear is T by main website_p, so, we can also draw calculating n_rAnother formula

$n_r=\frac{T_p}{T_r}$ (formula 9)

In the present embodiment, formula 8 both can be utilized to obtain n_r, it is also possible to utilize formula 9 to obtain n_r, it is possible to select according to practical situation.

Separately below the test process of different tested types of service is described in detail.

For service success rate.Service success rate in the present embodiment is namely in n business, success ratio shared by business, therefore, when test, except including in tested configuration parameter: tested nodes and tested data cell also include tested business frequency n and service interval t except identifying.Its overall flow is similar to flow process shown in Fig. 1, and simply concrete process foundation is test for type and adjusts accordingly.Further, according to described tested type, analyze the data of described transmission, obtain the process of test result as shown in Figure 4, including:

Step S41, obtaining in each tested process the data of transmission respectively, analyzing this business procedure is success or failure；

Step S42, acquisition business number of success m_sWith service fail number of times m_l；

Step S43, foundation service success rate η=m_s/(m_s+m_l) * 100% obtain test result.

And it is as follows wherein to analyze the process that business procedure is success or failure:

The data analyzing described transmission all include the data message in each stage in this business procedure and described data message all correct, this business success；

The data analyzing described transmission all do not include the data message in each stage in this business procedure or described data message not exclusively correct, this service fail.

For operation flow shown in Fig. 5, this operation flow is completed by these a series of MESSAGE EXCHANGE of message 1-5, if these a series of messages can both be accurately mutual, represent business success, otherwise, if wherein a certain message dropping or other mistakes, service fail occur.Such as, total calling service needed of power distribution automation business is sent by main website always calls order, and substation is replied after confirming order, according to 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 interval of transmission is determined by line parameter circuit value.Only complete all these action and could calculate a business success.

When described tested type is maximum throughput rate test, concrete, according to the principle corresponding with described tested type, the process being transmitted between described target service data source port in described tested data cell and destination interface is included:

Control described source port and send the business datum of predetermined quantity to destination interface according to the current speed that sets.

According to described tested type, analyze the data of described transmission, obtain the process of test result as shown in Figure 6, including:

Step S61, obtain described destination interface receive business datum amount；

Step S62, judge receive business datum amount whether less than predetermined quantity, if so, then perform step S63, if it is not, then perform step S64；

Whether the business datum amount received has two results less than predetermined quantity, less than, or be equal to.Do not have more than situation, so when receive business datum amount be not less than intended service data volume time, be namely described destination interface receive business datum amount equal 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 after reducing predetermined value, and return execution step S61；

Step S64, the transmission rate determining source port are maximum throughput rate.

When described tested type is the test of end-to-end average retardation, according to described tested type, analyzing the data of described transmission, the process obtaining test result is as follows:

First determine data to be transmitted block group set in advance, this transmission data chunk has multiple data block；

When after source port with destination interface time synchronized, transmit the data block in described data to be transmitted block group successively；Record the first bit data in each data block respectively to leave last bit data in time of source port and this data block and arrive the time of destination interface；Obtain the end-to-end time delay of each data block respectively；The end-to-end time delay meansigma methods determining each data block is end-to-end average retardation.

For one of them data block, in this data block, the first bit data leaves the time of source port is T₀, the time of last bit data arrival destination interface is T₁, then utilizing the end-to-end delay that this data block records is T_ete=T₁-T₀。

And when carrying out the test of round-trip delay, in data block, the time of last bit data arrival destination interface is T₁, destination interface can feed back an acknowledgement frame to source port, and record source port receives the time of acknowledgement frame and is designated as T_b.Round-trip delay rtt_c=T₁-T_b。

In addition, except above-mentioned test-types, also include the test of maximum concurrent connection number, test configurations parameter sets the number of the business of source port and destination interface needs test, the predetermined throughput of each service connection, according to described tested type, analyzing the data of described transmission, the detailed process obtaining test result is as follows:

Initially set up the connection of a business in predetermined business, after detection business datum reaches the predetermined throughput of this business, set up the connection of next business, after this business also reaches predetermined throughput, setting up next service connection, by that analogy, until newly-established service connection is unable to reach predetermined throughput, now, the quantity of the current service connection set up is maximum concurrent connection number.

In addition, system reliability test, tested business number of times and service interval in test configurations parameter are also included.Record the time that business each time is run continually and steadily, then go repeatedly to run the meansigma methods of time, as the system reliability service time.

The embodiment of the present application does not limit and only comprises above-mentioned test-types, and all system performance testing types being applied in power system all can be realized by disclosed embodiments, and this is no longer going to repeat them.Further, above-mentioned test result, it is also possible to by the outut device output display such as display or printer, in order to the performance of power system based on this, is estimated by tester.

Further, in order to realize the verity of test process, all can before described target service data be transmitted step between described tested data cell in each embodiment above-mentioned, obey the principle of Poisson distribution according to the packet arriving destination interface in the set time, generate background data bag and be transmitted.

It is, add background traffic in each test process, with consumption network bandwidth so that the process of analog service is truer.The content of this background traffic can take from stochastic flow file.And according to the analysis to packet arrival process: according to binomial distribution, arriving k in time t according to the probability wrapped is:

$P_t(x=k)=C_n^k{\left(\mathrm{\β\Δt}\right)}^k{(1-\mathrm{\β\Δt})}^{n-k}$ (formula 12)

Wherein $C_n^k=\frac{n!}{k!(n-k)!};$

Formula 12 is investigated further.As n → ∞,Binomial distribution is approximate obeys Poisson distribution, finally obtains:

$P_t(x=k)=\frac{e^{-\mathrm{\βt}}{\left(\mathrm{\βt}\right)}^k}{k!}$ (formula 13)

Formula 13 illustrates, arrives the k probability P according to bag in time t_t(x=k) Poisson distribution is obeyed.And, data packet interarrival times is obeyed and is uniformly distributed.
