Abstract
In a network where there are two local area networks (LANs) connected over a wide area network (WAN) by paralleled LAN to WAN devices at each end of the WAN, Transmission Control Protocol (TCP) connections may be requested by a first near end LAN to WAN device and received at a first far end LAN to WAN device but the acknowledgement may be returned to a second far end LAN to WAN device. The second far end LAN to WAN device contacts the first far end LAN to WAN device and the TCP connection is moved to the second far end LAN to WAN device, which provides the acknowledgement to the first near end LAN to WAN device to complete the TCP connection. Similar operations occur during active TCP connection operation but with certain queued data being flushed during the TCP connection transfer.
