1. A satellite communication system for providing network access over a shared satellite communication link, the satellite communication system comprising:

  • a user access point coupled to one or more user terminals that access a remote network;

    a network access point coupled to the remote network; and

    a satellite communications link wirelessly coupling the user access point and the network access point, wherein;

    the satellite communications link is at least partially controlled by the network access point,the network access point monitors information passed between the remote network and the user access point on a per web page basis to create an estimate of future usage of the satellite communications link by the user access point based on the information for a web page,the network access point allocates satellite communications link return channel resources for the user access point based on the estimate when the network access point receives a future request for the web page in anticipation of return channel needs for embedded elements of the web page,the estimate includes varying return channel need over a time frame, such that the estimate predicts when the user access point will request embedded elements of the web page, andwherein the estimate is developed from a plurality of web page requests that uses a smoothing filter biased toward recent requests.
