Embodiment Construction

[0036] The present disclosure provides embodiments for mitigating or eliminating problems arising from browsing the World Wide Web (WWW) over broadband satellite data links or other high latency data links. One of the problems addressed by the described embodiments is reducing the waiting time experienced by users. In the following description, specific details are given to provide a thorough understanding of the described embodiments. However, one of ordinary skill in the art would understand that these embodiments may be practiced without these specific details. For example, circuits may be shown in block diagrams in order not to obscure the embodiments in unnecessary detail. In other instances, well-known circuits, structures and techniques may be shown in detail in order not to obscure the embodiments.

[0037] Also, it is to be noted that the embodiments may be explained as processing procedures described with flowcharts, operation procedure diagrams, structural diagram...

Abstract

A method and apparatus for downloading a hyper text transfer protocol (HTTP) web page over a wireless link that couples a modem to a gateway. A transmission control protocol (TCP) link is opened between the gateway and the modem. A HTTP uniform resource identifier (URI) is received at the modem from a web browser, where the HTTP URI corresponds to the HTTP web page of an origin server. The TCP link is configured well before the web browser provides the URI. The HTTP URI is sent to the gateway. An Internet protocol (IP) address is determined for a domain name indicated in the HTTP URI by the gateway. The HTTP web page is retrieved by the gateway using the Internet, without the modem requesting it. The HTTP web page is transmitted to the satellite modem. Objects referenced in the HTTP web page are accessed similarly to the HTTP web page, but objects can also be accessed in parallel. In some cases, bandwidth is scaled for the TCP link according to loading of the modem.

Description

[0001] This application claims the benefit of non-provisional US Application Serial No. 60 / 555,605, filed March 22, 2004, which is hereby incorporated by reference in its entirety. [0002] This application is related to US Patent Application entitled "SATELLITEANTICIPATORY BANDWIDTH ACCELERATION" filed on the same date as this application (see Attorney Docket No. 040366), which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to broadband optimization, and more specifically, but not by way of limitation, to HTTP optimization over high-latency data links. Background technique [0004] The propagation delay added to any transmission by broadband geostationary satellites is about 250 ms. This obviously has the implication that any communication, that given communication on the sender is delayed by a quarter of a second before the receiver is able to react and respond to any communication. The TCP / IP protoco...
