Standard protocols, such as those commonly used on LAN networks, are used to connect nodes (104, 106, 108 and 110) to an enterprise network (102) via a wide area wireless network (100). Within the appropriate protocol stacks, the standard protocols are optimized by filtering some packets, eliminating and reducing the size of data packets. The optimized data packets can be transmitted over the wireless WAN, increasing WAN effici ency. The optimization is accomplished by inserting an additional optimization layer (610) into the stack between the existing layers. The optimization layer accepts the normal protocol signals generated by the surrounding layers and generates ou tputs which mimic protocol layers which the surrounding layers expect. Consequently, the optimization layer operates tra nsparently with respect to the existing protocol stack layers.
