Network card testing method

Abstract

The present invention discloses a network card testing method, through which the data transferring capability of two network cards, which are ready for test, can be tested in a single test process of a computer. One of the two network cards for test is used as a sending terminal network card and the other is used as a receiving terminal network card; in conformity to a test data status liked list and a linked list of the test configuration parameter and the network card information, the sending terminal network card sends the test data to the link layer through a plurality of drivers in turn and the actual bytes in the test data package, which are gained by the operational system, sent by the sending terminal network card and received by the receiving terminal network card, is compared with the original bytes in the test data package so as to judge the data transferring capability of the network cards for test. Hereby, the present invention overcomes the disadvantages of the present method that the service terminal or client terminal network is used for the test of the network cards.

Description

technical field [0001] The invention relates to a network card testing method, in particular to a method for simultaneously testing the data transmission performance of two network cards to be tested through a single test process. Background technique [0002] With the continuous development of computer networks, more and more people have come into contact with the Internet. Local area network is a kind of computer network, which is a network system that provides data exchange and resource sharing. One of the main devices that make up a local area network is a Network Interface Card (NIC) for short. The network card provides a physical connection for data communication between computers, and each computer must be installed with a network card if it needs to access the network. [0003] The network card is an indispensable basic device in the computer network. The failure of the network card will not only affect the workstation itself, but also often affect the normal opera...

Problems solved by technology

[0006] (2) Since the implementation of the existing test program is based on the socket (Socket), this means that in addition to the influence of the underlying driver, it will also be affected by the protocol stack above the link layer and the socket technology. As we all know, the more complex the link, the more variables there will be. For example, in the test, if the socket fails to be established or the socket receiving buffer is full due to system reasons, the test will also fail, and it may eventually fail. The test target deviates, and the more extreme case is to change from the original network card test to the network test

[0008] (1) Since some protocol stacks provide reliable transmission connections, there will be mechanisms such as continuous retrying for transmission connections in implementation, which will virtually cover up network card problems. For example: A network card has transmission performance problems, but due to There is a confirmation and retry mechanism in a certain protocol stack, which can finally complete the transmission through low-efficiency repetitions, but the upper layer does not feel data loss and other phenomena, and still thinks that the network card has sent and received data normally.

[0009] (2) It is relatively difficult to formulate the principles for judging the data transmission performance indicators of network cards. At present, it is still based on the success or failure of some application program interface (API) operations, so the detection efficiency is not high, and the test results are not very accurate.

[0010] (3) The indicators of the data receiving and sending capabilities of the same network card are mixed together, and there are still defects in the accuracy and clarity of the test results, which makes the testing and judgment of the testers inconvenient
