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.

26. An apparatus comprising:
-
an internet browser; and
a TCP/IP stack for use with said internet browser, wherein said internet browser sends a packet across the Internet to a second apparatus through (a) said TCP/IP stack, (b) a Network layer tunnel between said TCP/IP stack of said apparatus and a gateway apparatus, and (c) means for transmitting packets from the gateway apparatus to the second apparatus, wherein a Network layer source address of a packet of the Network layer tunnel is different from a source IP address of an IP packet received by the Network layer tunnel from said TCP/IP stack. - View Dependent Claims (27, 31, 33)
