Description

A kind of network card testing method and system
Technical field
The present invention relates to compunication, be specifically related to a kind of network card testing method and system, relate in particular to a kind of method of testing and system that can test a plurality of network interface cards automatically simultaneously.
Background technology
Network interface card is one of hardware of computer indispensability, is the critical point, first road of compunication, and the performance of network interface card has determined to receive and transmit the quality of communication service.The performance test of network interface card is the important leverage before the brand computer communication services.
In the method for existing test network interface card, all network interface card machines to be measured all are connected on the same switch, the tester must be on all machines to be tested installation testing instrument or script carry out test, length consuming time, tester's task is heavy.
Existing network interface card method for testing performance mainly contains and comprises three parts: the detection of network interface card general utility functions, network interface card Performance Detection and network interface card Detection of Stability.
Existing network interface card method for testing performance owing to do not have corresponding test script or instrument to use, has caused the tester to pay supernumerary worker's cost in the functional testing process of generality, has increased the testing complex degree, and the testing time is obviously increased.
In network interface card Performance Detection process, owing to be artificial calculate throughput, the metering time is often inaccurate, has so just caused the inaccurate of test result.In the performance test process, if relate to the network card performance testing more than three, just must calculate the time and the response data of three nodes simultaneously, because neither one writes down result's instrument automatically, this has increased tester's workload undoubtedly, must wait for that an EOT goes to carry out afterwards next one test again.And adopt dedicated hardware testing equipment, high cost to become the misgivings that general enterprise is selected.
The stability test of existing network interface card is generally ordered by ping and is finished, and the data traffic that the ping order produces is very little usually, can't cause limit load to network interface card, and the true stability of network interface card can't embody like this.The second method of existing network interface card stability test mainly causes network interface card pressure by file transfer, this method of testing can produce pressure to network interface card to a certain extent, but can not continue to produce pressure to network interface card, in order to address this problem, after the tester must treat manually that a file transfer finishes, then transmit next file again, even and so do not reach a kind of lasting pressure yet, also increased tester's amount of labour.
Summary of the invention
