Viprinet’s Node Stacking enables coupling several Multichannel VPN Routers to one virtual super router managing the bandwidth of all coupled devices’ WAN connections. The Node Stacking network is controlled by a fixed router, the master. If the master itself fails, another Multichannel VPN Router takes over its role within only a few seconds. If a slave fails, only bandwidth decreases.
Altogether, with the Viprinet software licenses for Node Stacking and Hub Redundancy in connection with the use of various WAN media (wired/wireless, different technologies, different providers), an Internet link with a maximum annual availability of over 99.9% can be formed. The coupled routers can be devices from different series; the respectively strongest device in the network should be the master.
