Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The switching test environment of the Gigabit network card in the Gigabit network environment is as follows: figure 1 As shown, the server is configured with two Gigabit Ethernet cards for binding and mutual backup operation. The two network cards are connected to the Gigabit switch through the Gigabit network cable. The client machine uses a network card and is also connected to the Gigabit switch. Through Unplug and insert the network cable from the server-side network card to the switch on the switch to simulate a network link failure.

[0037] The switching test environment also includes a server-side packet sending program and a client-side packet receiving program. For the actual situation of the present invention, my test environment mainly includes a packet sending program and a packet receiving program, that is, the se...

Abstract

The invention relates to a method for rapidly switching gigabit network cards in a gigabit switching environment. In the method, a timer used for polling a network card register is arranged in a gigabit network card equipment driver, detects a network link state change by polling contents of the network card register, and when a link state is changed from connection to breaking, sets a link statechange bit of a network card interruption register to trigger the interruption of the link state change in advance. The improved gigabit network card equipment driver in the method can detect a link breaking state only in less than 100 milliseconds. Therefore, the link breaking perceiving performance of the network card driver is greatly improved.

Description

technical field [0001] The invention relates to a high-availability technology in the field of computers, in particular to a method for quickly switching gigabit network cards in a gigabit switching environment. Background technique [0002] Due to the special status of the server, maintaining high availability and security of the server is an important indicator of the enterprise-level IT environment. The most important point is the high availability of the server network connection. With the development of network technology, the scale of the network is gradually increasing. . Network card bonding technology is one of the effective methods to improve the availability and reliability of server network connections. Multi-network card binding is to bind two or more network cards to the same IP address through software and hardware settings, and use it as if using one network card. Many high-end server network cards (such as intel8254x series, 3COM server network cards, etc....
