Abstract
Traffic transmitted over long fat networks (LFN) can be expensive and/or slow. The amount of traffic is reduced by application of the present invention which introduces a manipulator device at each end of a long fat network. The manipulator device emulates the opposing end-side equipment for the local-side equipment and then communications over the long fat network using an established tunnel. Thus, the protocol exchanges that would normally be transmitted over the long fat network in setting up, tearing down and controlling a communications session are reduced or eliminated. Yet an alternate embodiment may use a single manipulator device at a central operator premises of the LFN. The single manipulator device may replace domain names that are embedded within a markup language file with their IP addresses.
