Abstract
Methods for pipelining, piggybacking, and transporting cross layer parameters through a network to reduce round-trip times are disclosed. Application activation, such as accessing a web-site through the internet, currently uses several protocols, including DNS Name resolution, establishing a TCP connection, sending HTTP Request and getting HTTP-Response that contains the web-page data, before the data from the web-site can be displayed to the user. Such operations take several round-trips through the transit network and are of the order of 100 to 200 milliseconds in the wireless access network in the best case. A method of generating a multi-part message to reduce these round trip is disclosed, as well as a proxy device which minimizes client side round trips while utilizing standard messaging in the wireline network. The invention includes client side user parameter gathering when specifying the application first (pre-fix), or specifying the application last (post-fix).
