Abstract
A system in which a personal computer sends messages into a network such as a TCP/IP network using a conventional dial-up link and downloads data from the TCI/IP network using a high-speed one-way satellite link. A preferred embodiment uses a conventional SLIP provider to connect to the TCP/IP network and uses a commercial software TCP/IP package that has a standard driver interface. A spoofing protocol compensates for the long propagation delays inherent to satellite communication.
