Abstract
A system in which a personal computer sends messages into a TCP/IP network using a conventional dial-up link and downloads data from the TCP/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.

17. A system comprising:
-
a device configured to interface a satellite antenna unit with a computer; and
computer-processable code for execution on the computer, wherein said device and said computer-processable code are configured such that (a) a TCP/IP packet generated by a TCP/IP stack of the computer is encapsulated in an ethernet packet which is stripped off before the packet is sent to the internet, (b) a TCP/IP packet received through the satellite antenna unit from the internet is scanned to determine if the destination IP address matches a predetermined IP address, and if a match is found then the TCP/IP packet is encapsulated in an ethernet packet and passed to the TCP/IP stack of the computer. - View Dependent Claims (18, 19, 20)
