Network card test system

Abstract

The invention discloses a network card test system which comprises a network card test device, a network card, and network card test software. A plurality of paired twisted-pair lines in the network card test device are connected mutually and respectively so as to form a loop. After the network card test device is connected to the network card, the test loop is formed. The test system implements the network card test software through a computer, and generates a test data package for being transmitted by a data link layer directly according to different test strategies and network card information. And then the test data package is returned by the formed test loop, and the test result is tested according to the test data package.

Description

technical field [0001] The present invention relates to a network card testing system, in particular to a network card testing system that forms a testing loop through an external testing device. Background technique [0002] According to different communication technologies, layout methods, and transmission media, there are different network architectures, such as Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), Fast Ethernet ), and Wireless Network, etc. These networks have their specific form factors and supported operating bandwidths. For example, the Ethernet uses a relatively inexpensive twisted pair cable as a signal transmission medium. Because the Ethernet has the characteristics of simple wiring and easy network construction and expansion, it has become the most commonly used network. Early Ethernet networks used half-duplex network cards (100Base-T network cards), which supported a transmission bandwidth of 10Mbit / s. With the development of networ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a network card test system, which directly sends test data packets through the bottom layer, and receives the test data packets transmitted by itself through the test loop, so as to self-test the effectiveness of network card sending and receiving processing packets, thereby solving the problem of In the prior art, the network card test is complex and time-consuming, requires additional network equipment, and cannot test the underlying performance, etc.
