Abstract: A controller is provided for increasing bandwidth between a local area network (“LAN”) and other networks by using multiple routers on the given LAN. Data packets are multiplexed between the routers using a novel variation on the standard SYN packet synchronization protocol, and other components. On receiving data destined for an external network, the controller or gateway computer will direct the data to the appropriate router. In addition to providing higher speed connections, the invention provides better fault tolerance in the form of redundant connections from the originating LAN to a wide area network such as the Internet.
