Abstract

An embodiment of the invention provides a redundancy backup method and terminal and a video network system. The redundancy backup method and terminal are applied to a video network. The video network comprises a terminal. The terminal comprises a master network card and a standby network card. The method comprises the following steps: configuring same physical address MAC addresses for the master network card and the standby network card; and when detecting the currently-started master network card is abnormal, adopting the standby network card to carry out redundancy switching. ARP re-addressing broadcast can be avoided, and reconnection speed is fast.

Description

technical field [0001] The present invention relates to the technical field of video networking, in particular to a redundant backup method, a redundant backup terminal, and a video networking system. Background technique [0002] As the core of the enterprise information platform, the server's stability and security are very important, and the network link connecting the server is a particularly important link. Redundant backup technology is a redundant backup of error-prone hardware devices. When one of the devices fails to work normally for some reason, another device can immediately replace this device to complete the same function. In a system that requires high reliability of network communication, it is necessary to perform dual-redundancy backup on the network card. When the normal communication network card or line fails, it can automatically switch to the backup network card, which can strengthen the system network link and reduce the failure rate. [0003] In th...
