Description

The RFC2544 consensus standard method that is used for the wireless device performance test

Technical field

The invention belongs to the network test and measurement technical field, specifically, relate to a kind of RFC2544 consensus standard method for the wireless device performance test.

Background technology

The TCP/IP network system is a kind of high isomerism, open complex giant system.Network test, measurement are the effective ways of understanding network behavior, phase-split network flow.Current, the test of wireless network is an emphasis in network test and measurement field.But the RFC agreement of Wireless Communication Equipment performance test is not caught up with the quick rhythm of wireless application development.

The performance test methods of traditional wireless device mainly is to carry out with testing software.But there is larger natural defect in such testing software: tested person host performance impact is large, without unified standard, be difficult to the standard testing result that provides reliable and stable.And, with the mode of testing software, can't adopt the applied in network performance test agreement RFC2544 of standard.

But such software test method is the main flow of Wireless Communication Equipment performance test always, such as employed ixchariot in " building and performance test based on the wireless Mesh netword of 802.11 agreements "

It is exactly the classics representative of wireless test software.

As shown in Figure 1, this is a wireless test case, the ixchariot test period, and gained performance numerical value is being shaken always, can't obtain precise results, near the moment data value that has even fall the 0M.And owing to make bag, give out a contract for a project and packet receiving is added up and all to be needed to expend ample resources, numerical value is also lower slightly than real result.Can only average as the performance test results roughly at last.

Summary of the invention

It is simple to the purpose of this invention is to provide a kind of method, and result standard is reliable, can make wired tester with the method for testing of the accurate testing radio equipment of RFC agreement, is called RFC2544 consensus standard method.

RFC 2544 agreements of IETF are called as the Holy Bible of applied in network performance test, the performance of only consulting and using this protocol test wireless device just has most convincingness, and, development along with wireless communication technology, 802.11 serial wireless network standards agreement development, especially since the product promotion of 802.11n consensus standard, its in theory throughput reached 300 M bps.High throughput performance for 300Mbps, small shake in the software test all may bring huge error, therefore, use high-intensity tester, standard agreement with reference to RFC 2544 applied in network performance test, stablize, test reliably, exactly the performance of Wireless Communication Equipment, have urgency and necessity.

The RFC2544 consensus standard method of a kind of wireless device performance test provided by the invention, its concrete steps are as follows:

1) two wireless device configuration is become bridge mode, with the wired mouthful of input from a wireless device of the flow of cable network tester, bridge joint by wireless is delivered on another wireless device again, and gets back to the cable network tester from wired mouthful of output of this wireless device;

2) according to the RFC 2544 protocol test modules that carry on the tester of finite element network described in the step 1), parameter is disposed by normal mode, and take 1% packet loss as lower limit, wherein said parameter comprises that test period, bag size, testing time, test are worth scope and initial rate most;

3) operation test, with reference to RFC2544 agreement operation 1～2 time, acquired results namely is the standard value of Radio Test Equipment performance.

Among the present invention, step 2) test period is 60 seconds described in.

Among the present invention, step 2) size of bag described in is 64byte, 128byte, 256byte, 512byte, 1024byte or 1518byte.

Among the present invention, described wireless device is mainly wireless aps, comprises the AP of bridge joint between the support AP of the large AP of the AP of AP, CISCO company of ARUBA company and each manufacturer.

Among the present invention, the employed network tester of this method of testing is the official testing instrument, only require tester can use the configuration of RFC2544 agreement, domestic current more famous network tester comprises the XM series of Testcenter tester or the Ixia of Spirent, 400T testers etc. are all supported the standard testing of RFC2544 agreement at present.

The present invention has following beneficial effect:

1) use by tester, and the application of RFC2544 standard agreement improves the accuracy of wireless device performance test greatly;

2) the private radio tester is also arranged on the Vehicles Collected from Market, but its price is extremely high, and itself can't adopts RFC 2544 agreements, its accuracy also can't contrast with this method of testing;

3) operation of this method of testing will promote RFC 2544 agreements in the application in wireless device field, promote the standard progress of wireless domain development.

Embodiment

Below in conjunction with drawings and Examples the present invention is described in further detail.

Embodiment 1

Wireless device is take AP as example, and tester teaches the TestCenter at scientific network IPv6 test and appraisal centers, laboratory (building jointly with Information Office of Fudan University) as example take Shanghai.

1) as shown in Figure 2, two AP are configured to bridge mode, both are by the mutual bridge joint of Configuration, and difference connects upper TestCenter as follows;

2) flow of network tester is from the wired mouthful of input of an end AP, and the bridge joint by wireless is delivered to other end AP again, and exports from wired mouthful of this AP and get back to tester;

3) the RFC 2544 protocol test modules that carry according to tester, and perform corresponding configuration, test period, bag size, testing time, test are worth the parameters such as scope and initial rate most disposes by normal mode, and take 1% packet loss as lower limit (wireless 0% packet loss can't guarantee that this is open by channel and vulnerability to jamming determines);

4) operation test, with reference to RFC2544 agreement operation 1-2 time, acquired results namely is the standard value of Radio Test Equipment performance.

Test according to the RFC2544 agreement is carried out for the AP of three regular manufacturers in the test and appraisal center, the 1518 byte packet one-way transmission data that 802.11n agreement under the 2.4G frequency is adopted in test throughput obtain test result.

Under the specific embodiment: the testing throughput that the AP product utilization network tester of A, B, C three companies has been carried out respectively observing the RFC2544 agreement.Test environment: under noiseless environment, AP to be measured closely puts, and all adopts the 802.11n agreement, links to each other by the bridge joint mode is wireless.All having adopted Bao Changwei 1518 bytes, cycle in the test is 60 seconds and 1% packet loss is set is minimum packet loss threshold value; The throughput of surveying is unidirectional maximum throughput.Wherein, the product A P of A company is called a, gained test report result such as Fig. 3, as shown in Figure 4:

According to the test result of RFC2544 agreement, the throughput of AP product a is 31.625%; Wherein the report of Fig. 3 also has the synchronous recording of test process; Therewith in like manner, the throughput that also records product b and c is respectively 10.875% and 30%.

Manufacturer all represents to accept to test result under each product.Through contrast, a product and c product all record desired result under the RFC2544 agreement, and can repeat by the measured result of RFC2544 agreement in the tester, and error is far smaller than error and the fluctuation of software test.The test result of b product slightly fluctuates, but further investigation reveals that, the said firm's AP product just emerges, and also still less than the fluctuation of software test, acquired results also meets their expection to the fluctuation under the test of RFC2544 standard agreement fully.

Therefore, the inventive method that the RFC2544 agreement is tested the throughput performance of AP equipment in conjunction with network tester can obtain standard results accurate stable, has good universality, is the new progress of wireless aps device throughput measuring technology.
