Abstract
A network interface performance testing method comprises the following steps: a contract-issuing procedure is arranged into an interrupt service routine of a timer of a veneer of a contract-issuing network interface; when the tested network interface exists and the timer starts, the timer controls the contract-issuing network interface and sends a data package to a contract-receiving network interface, and a counter counts the relevant testing data; the contract-issuing network interface or the contract-receiving network interface is the tested network interface; after the contract-issuing network interface stops sending contract package, the timer stops working; the performance index of the tested network interface is calculated according to the relevant testing data. The invention applies the method which can control the times of sending contract package per minute and the amounts needed in sending contract package through the timer, and get a higher speed in sending contract package and a precise flow control in order to meet the needs in testing the performance of the network interface.

Embodiment
To combine accompanying drawing and embodiment that technical scheme of the present invention is explained in more detail below.
Through introducing the network port performance test that is applied to the method the mobile communication base station veneer, further specify this and send described network port performance method of testing below.
Concrete test process is as shown in Figure 1, may further comprise the steps (wherein, give out a contract for a project network interface with connect the bag network interface one of them for tested network interface, and the two is on same veneer or different veneer, and also possibly be same network interface):
1, starts respectively and give out a contract for a project network interface and connect the veneer at bag network interface place and its required separately various parameters are set.For the parameter of the network interface place veneer setting of giving out a contract for a project comprises: the physical address of tested network interface numbering, test pattern (being set to only send packet and loopback test (, pattern for this reason being set)), tested network interface when giving out a contract for a project network interface when connecing the bag network interface and be same network interface, at every turn send the burst packets number, send frame length (unit is a byte/frame), transmitted traffic (unit is Mb/s) and send duration parameters such as (unit are second).The test pattern that connects bag network interface place veneer is set to receive only packet.Also can be connect bag network interface place veneer be provided with the physical address of tested network interface numbering, tested network interface, at every turn send the burst packets number, send frame length, transmitted traffic and send parameters such as duration; But the test pattern that detects this veneer when the software program on this veneer is when receiving only packet; It can neglect above-mentioned set parameter; Promptly only accept packet, do not send packet.The above-mentioned step that parameter is set can through but be not limited to realize through the program on the veneer terminal (being display unit) that links to each other with above-mentioned veneer.Input test order (like NetTest) is as shown in Figure 2 on this veneer terminal, can demonstrate the parameter that needs setting on the veneer terminal, and user manually input gets final product.Wherein sending burst packets, to count default value be 1, and the transmitted traffic default value is 5.In test pattern, 0 expression loopback test, packet is only sent in 1 expression, and 2 expressions receive only packet;
2, the software program that operates on the veneer judges according to above-mentioned parameter whether tested network interface exists.If exist, then carry out next step;
3, the relevant work of initialization test.The transmitting-receiving bag quantity that reset counter, this counter mainly are used for adding up network interface and actual testing time etc.; Create print server and test relevant information with printout;
4, be provided for control timer startup, correlation function such as stop, and the program of giving out a contract for a project is set to the interrupt service routine of timer; (this step also can be carried out before step 1)
5, after timer started, its control network interface of giving out a contract for a project began to send packet according to the above-mentioned setting parameter of giving out a contract for a project to connecing the bag network interface.Wherein, the bag number that timer interruption frequency=per second will send/at every turn send the burst packets number, and bag number=transmitted traffic that per second will send/transmission frame length.Every like this at a distance from an interrupt cycle, the network interface of giving out a contract for a project just is provided with the transmission packet according to appointment.Utilize the counters count relevant test data simultaneously, like: the bag number that the upper-layer protocol of give out a contract for a project network interface and transmitting-receiving bag quantity, the network interface of the giving out a contract for a project place veneer that connects the bag network interface sends to this network interface of giving out a contract for a project, connect bag number that the bag network interface sends the upper-layer protocol of its place veneer to, testing time etc.;
When 6, the time of process transmission duration or tester initiatively stopped to test, the network interface of giving out a contract for a project stopped to send packet, and timer quits work.Add up each test index according to above-mentioned relevant test data, and these data are exported at print window through print server.The network interface of giving out a contract for a project place veneer is printed the bag number of issuing tested network interface in the upper strata and the network interface of giving out a contract for a project and is sent the bag number; Connecing bag network interface place veneer prints and connects the bag number that the bag network interface sends to the upper strata and connect bag network interface receiver packet number with this.Simultaneously can count packet loss and hardware packet loss according to above-mentioned data: wherein packet loss=(upper-layer protocol of the network interface of giving out a contract for a project place veneer is issued the bag number of this network interface of giving out a contract for a project-the connect bag number that the bag network interface sends to the upper-layer protocol of its place veneer)/network interface of giving out a contract for a project upper-layer protocol of belonging to veneer is issued the bag number of this network interface of giving out a contract for a project; Hardware packet loss=(network interface of giving out a contract for a project transmission bag number-connect and wrap the network interface receiver packet number)/network interface of giving out a contract for a project sends the bag number.
This method looks for another way, and with the method for giving out a contract for a project that timer control is given out a contract for a project and optimized, can control each transmission burst packets number, send frame length (byte/frame), transmitted traffic, testing time etc., can obtain high give out a contract for a project speed and flow control accurately.Can count simultaneously transmissions, reception flow accurately, packet loss, hardware packet loss etc. can test out the service behaviour of network interface accurately.In today that network technology is generally adopted, this method will have abundant and huge application potential.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
