The Local Area Network (LAN) is used for providing data communications between various data communication devices. Automated routing control system supersedes the prior approach to LAN redundancy which provides two or more LANs and each has a Local Area Network (LAN) controller coupled to data communication devices. Devices require some software to switch between the network LAN controllers to counter some network segment failures. This approach is proven to be very costly due to demands for “Off-the-shelf” data communication devices with built-in LAN controller drivers.
