  • Method and apparatus for improving efficiency of TCP/IP protocol over high delay-bandwidth network
    Patent number: 6415329
    Abstract: A method of communicating over a satellite or other high delay-bandwidth link comprises receiving, at a source or client gateway, incoming packets directed to a destination address, in a first protocol, preferably transmission control protocol (TCP) over Internet protocol (IP), or TCP/IP. The destination address is modified by replacing the destination address in a received packet with an address of the source gateway application so that the packets are forwarded to the source gateway application. Packets are forwarded from the source gateway application in a second protocol over the link to a destination gateway application. The original destination address is restored at the destination gateway application and the packets are forwarded to the destination address in the first protocol. Packets may be transmitted or forwarded over the link by first fragmenting them into smaller packets, and are reconstructed at the other end of the link.
