Claim:
1. A method of optimizing data transmission across a wide area network (WAN), comprising: providing a data transmission protocol stack comprising a transmission control protocol (TCP) layer that exchanges data processed by one or more hosts of the WAN, and an Internet Protocol (IP) layer that transports datagrams encapsulating the data to routers in the WAN; defining, for use by network interface device components, a user datagram protocol (UDP)-based transmission layer within the data transmission protocol stack and that interfaces with the TCP layer and that transmits data and control packets between the network interface device components of hosts and receivers of the WAN using a unicast duplex protocol; and defining, for the network interface device components, a WAN optimization components (WOC) layer within the data transmission protocol stack and that interacts with the UDP-based transmission layer in the network interface device components, and provides transport protocol optimization of big data transfers through the UDP-based transmission layer by transparently intercepting TCP transfers from one or more applications generating the data transmission and defining modified routing rules so that application traffic is directed to appropriate WOC home nodes to prevent a need to modify any of the one or more applications.
