Abstract
The present invention relates to telecommunications devices, systems and methods for providing improved performance over long latency communications links. Some embodiments selectively pre-fetch and transmit information over the link using improved protocol and pre-fetch mechanisms. One system includes a first gateway (430) adapted to communicate with a client (410), the first gateway including a processor coupled to a storage medium. The storage medium includes code for receiving a request for retrieving a web object, code for forwarding the request to a second gateway (440) over the long latency link, and code for receiving a pre-fetch announcement and response data for the web object from the second gateway. The pre-fetch announcement is received prior to receiving the response data.
