Embodiment Construction

[0013] like figure 1 Shown is a system architecture diagram of a preferred embodiment of the network card transmission speed testing system of the present invention. The system architecture of this preferred embodiment mainly includes a computer 1 , an input device 3 , and an output device 4 . The computer 1 includes a first network card 11 , a second network card 12 , a CPU (Central processing unit, central processing unit) 13 , a storage device 14 and a bus 15 . The first network card 11 , the second network card 12 , the CPU 13 , and the storage device 14 are all connected to the bus 15 , through which data can be exchanged with each other. The first network card 11 and the second network card 12 may be onboard network cards, or external network cards. The first network card 11 and the second network card 12 are connected point-to-point through a network cable. Among them, the network cable for point-to-point connection should be made as a crossover cable, that is, one e...

Abstract

The invention provides a LAN speed testing method, the steps of the method are: the IP addresses of a first network card and a second network card are arranged; the IP address of a virtual network card and an MAC address are also configured. The second network card is designed to a promiscuous mode. The network transmitting speed index is set. The IP address of the virtual network card and the MAC address are detected. According to the IP address of the virtual network card and the MAC address, a certain amount of databases are sent to the virtual network card by passing through a first network card. The data packet sent to the virtual network card is captured by the second network card. The capture time needed by capturing the entire data packet is counted. According to the size of the sent base packet and the capture time, the minimal network card transmitting speed when the first network card connects with the second network card is counted. Then whether the minimal network card transmitting speed excesses the set network transmitting speed index can be judged. The invention also provides a network transmitting testing system. With the invention, the transmission performances of the two network cards in one computer can be tested.

Description

technical field [0001] The invention relates to a computer peripheral equipment test system and method, in particular to a network card transmission speed test system and method. Background technique [0002] With the continuous development of computer networks, more and more people 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 LAN is the network card. A network card, also called a network adapter card or a network interface card (Network Interface Card), provides a physical connection for data communication between computers. [0003] The working principle of the network card is to organize the data sent by the computer to the network and decompose the data into data packets of appropriate size, then send them to the network, and also accept the data packets transmitted from the network. Specifically, when sending dat...
