Isolation network card for transparent computing terminal as well as application and network switching method thereof

Abstract

The invention discloses an isolation network card for a transparent computing terminal as well as application and a network switching method thereof. The isolation network card comprises at least two network interfaces used for connecting to a network, a network interface change-over switch used for selecting the network interface to be started for use, a switching controller which is used for establishing a connection between a mainboard interface and the network interface to be started for use according to the selection of the network interface change-over switch and generating a reset signal, a reset interface used for outputting the reset signal, and the mainboard interface used for communicating with a mainboard, wherein the network interfaces, the network interface change-over switch, the reset interface and the mainboard interface are respectively connected with the switching controller. The isolation network card has the advantages of being safe, convenient and fast to switch, simple in structure, low in cost, and the like.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to an isolated network card, an application and a network switching method for a transparent computing terminal. Background technique [0002] With the maturity and rapid development of Internet technology, Internet technology has been integrated into all aspects of production and life. While the Internet brings people the convenience of quickly obtaining information, its threat to the user's network security has increasingly become a hot and worrying issue. Especially for governments and public institutions, once their confidential data is leaked, the impact on them will be unimaginable. The isolation network card in the prior art, such as the Chinese patent No. 200520057156.X, realizes network isolation by switching the network port and selecting the corresponding hard disk at the same time, but this is not suitable for transparent computing terminals. Therefore, It is urgent to...
