Embodiment Construction

[0033] The technical scheme of the patent of the present invention is described below in conjunction with accompanying drawing.

[0034] The invention includes: constructing a 1:2 type middle-layer network card driving strategy, detecting faults and double-network switching algorithms, and obtaining a virtual network card communication configuration algorithm. The 1:2 middle layer network card driver policy is responsible for driving a virtual network card and two physical network cards for Ethernet network communication. The fault detection and dual-network switching algorithm is responsible for detecting the physical link failure of the network card; when the working network card fails and the backup network card is normal, the dual-network switching is performed. The dual-network switching includes changing the number of the working physical network card to change the physical network card through which the communication and control messages pass. Construct ARP request mess...

Abstract

The invention discloses a next network card redundancy switching method of a Windows Xp operating system. The method comprises the step of establishing a 1:2 type middle layer network card drive strategy, the step of detecting a fault and a dual-network switching algorithm and the step of obtaining a virtual network card communication configuration algorithm. The next network card redundancy switching method has the advantages that the method has the network card hardware independence and supports physical network cards of most manufactures, and the redundancy of three communication manners including the network card broadcasting request, broadcasting and multicast can be switched over.

Description

technical field [0001] The invention relates to the technical field of redundant switchover of computer network cards, in particular to a redundant switchover method for network cards under the WindowsXp operating system, which is applied to double-redundant network cards of computers installed with the WindowsXp operating system for double-network switchover. Background technique [0002] In industries such as telecommunications and finance that require highly reliable Ethernet networks, network terminals must implement dual redundant networks. At present, 3Com has implemented many functions including fault-tolerant redundancy on its network cards. Using DynamicAccess software, 2 to 4 network cards can be configured in a server, one as the main network card, and the rest as backup network cards. If the main link fails (switch port failure, main network card failure, line failure, etc.), the backup link is automatically activated to take over. Sun has the Trunking technolog...
