Lanner’s Advanced Generation LAN Bypass for Reliable Network Traffic

Many of today’s networking devices are built with LAN bypass function to prevent failed LAN transmission from impeding important in-flow critical data. The function is to ensure fault-tolerance for network appliances so that essential communications can be still continued even when software, hardware or power failure occurs. The basic idea of bypass is “cross-connection”. When an Ethernet port fails, the dysfunctional port will be temporarily disconnected from the system interface and all the in-line data will flow into the other LAN port so that data is still received.
