  • Applications

Nowadays, network technology has penetrated into every corner of the world, from various industries to the daily life of the public. The network has long been transformed from a simple platform for carrying information to a platform for providing critical services and public services that need to be online at any time.Because of this, the robustness and reliability of network infrastructure has never been more important.

In order to ensure the reliability of network, it is a common technology to construct redundant network system by using redundant backup technology in network design.The experience of redundant networks is that users barely notice when a network link breaks or changes.For the delay sensitive service, the switching time of the main and backup links is directly related to the availability of the system.

WN204 high speed switching redundant network card is a 4 port gigabit network interface card with redundant link high speed switching function.In addition to providing high-performance gigabit network interfaces for desktop, server, and other network devices, WN204 innovatively provides independent redundant links, and has the high-speed automatic switching ability of master/backup links, switching time delay 1sm, making the network truly capable of "always online" at the level of link connectivity.
