Description
Technical field
The present invention relates to network communications technology field, relate in particular to the method and the device that in the Internet QoS granularity and the precision of the network equipment are carried out automatic test.
Background technology
In traditional I P network; All messages are all treated by nondistinctive being equal to; Each router all adopts the strategy of FIFO (FIFO) to handle to all messages; It do one's best (Best-Effort) message is delivered to the destination, but performances such as the reliability that message is transmitted, propagation delay do not provide any assurance.
Network development is maked rapid progress; Along with new continuous appearance of using on the IP network, new requirement has also been proposed for the service quality of IP network, for example VoIP (Voice over IP; Ip voice) etc. real time business has just proposed high requirement to the transmission delay of message; If it is oversize that message transmits time-delay, will be user institute unacceptable (comparatively speaking, E-Mail and ftp business are to time delay and insensitive).Business such as voice, video and data in order to support to have different demands for services require network can distinguish different communication, and then corresponding service are provided for it.
The various traffic categorys in the network can not discerned and distinguish to the best effort of traditional IP; And the separating capacity that possesses traffic category provides the prerequisite of different services just for different communication, and the best effort pattern of legacy network can not satisfy the needs of application thus.The appearance of QoS (Quality of Service, service quality) technology just is devoted to address this problem.
QoS is intended to the different demands to various application, for it provides different service quality, for example: dedicated bandwidth is provided, reduces the message dropping rate, reduces message transfer delay and time delay shake etc.For realizing above-mentioned purpose, QoS provides following function:
1) message classification and painted
2) network congestion management
3) network congestion is avoided
4) traffic policing and traffic shaping
Wherein, traffic policing (Policing) and traffic shaping (Shaping) are functions most important and commonly used among the QoS, and the granularity of traffic policing and traffic shaping and precision are to weigh a very important index of QoS performance.

Step 3, accuracy test module read said granularity, and according to the precision Configuration Values of said granularity configuration Devices to test, and compare record with the real output value of tester;
Step 4, interpretation of result logging modle write down the data that produce in the test process, and data are analyzed output.
Further, in the said step 2, adjust the granularity that device configuration values obtains equipment through two fens algorithms.
In the said step 2,, adopt when said Configuration Values during greater than tester actual grain size output valve:
Y=Y-(Y-X)/2
Adjust this Configuration Values, wherein: Y is this Configuration Values, and X is last Configuration Values.
When said Configuration Values during, adopt less than tester actual grain size output valve:
Y=Y+(Y-X)/2
Adjust this Configuration Values, wherein: Y is this Configuration Values, and X is last Configuration Values.
When said Configuration Values equaled the actual grain size output valve of tester, this Configuration Values was the equipment granularity line output of going forward side by side.
In the said step 3, said precision Configuration Values layoutprocedure is:
Generate the committed information rate tabulation according to importing long data packet kilsyth basalt and said granularity;
Read a packet long value, and according to the data flow of this packet long value configuration testing appearance, record tester output valve repeats aforesaid operations, for empty, then finishes test until the long data packet tabulation.
If the bag long list of said packet is not empty, then read said packet next committed information rate value and write down the corresponding actual test value of tester, all run through until all committed information rates.
The precision that writes down in the said interpretation of result logging modle is the ratio of the committed information rate actual test value corresponding with tester.
The present invention has also disclosed the automatic test device of a kind of QoS granularity and precision, comprising:
Equipment and tester configuration module are used for Devices to test and tester are carried out initialization QoS configuration respectively;
The testing graininess module is used for the granularity of measuring equipment;
The accuracy test module is used to read said granularity, and according to the precision of this granularity measuring equipment;
The interpretation of result logging modle is used for writing down the data that test process produces, and data is analyzed output.
Wherein, said testing graininess module is passed through the Configuration Values and the tester actual grain size output valve of fetch equipment, and obtains granularity through two fens algorithm commissioning device Configuration Values.
Compared with prior art, the QoS granularity of the present invention's proposition and the automated testing method of precision and the beneficial effect of device have:
One, the collocation method of built-in a plurality of vendor equipment, and expansion interface is provided, can be to different testing equipments, extensibility is good;
Two, full-automatic test need not manual intervention, has avoided the great amount of manpower resource to do the work of repetition, has reduced the cost of test;
Three, support test result synchronous recording and Macro or mass analysis to export as the Excel file, visual pattern is conveniently filed test result;
Four, simplify test process, improved the utilance of test resource.
