Wenzhan technology launches a redundant link network card based on FPGA


In April 2019, wenzhan technology launched WN204 (redundant link network card), which is based on FPGA design and adopts innovative technology to shorten the switching time of main and standby links to less than 1 millisecond and greatly improve the reliability of the system. 

WN204 pairs of outgoing 4 Ethernet ports are divided into 2 independent double redundant links, each group is 1 1 hot backup.When the main link fails, the board will automatically switch to the standby link without the participation of the host, which greatly shortens the switching time and reduces the number of packet loss in the link switching process.The network card is widely used in a variety of servers, computers, industrial PC and custom equipment, support Windows and Linux and other common operating systems.2 gigabit Ethernet interfaces are reserved between the network card and the host, which can be used for data encryption or function expansion, and customized development can be made according to customer requirements.

The launch of WN204 has changed the high delay and uncontrollability generated by the traditional double-link redundant network card switching links through the operating system, greatly improved the reliability of the network system and won the recognition of the majority of customers.
