  • Platform independent data communication system and method
    Patent number: 5517636
    Abstract: This invention teaches a method and system for a computer program to accomplish communication in a computer environment which is independent of the system upon which the program is executing. This computer environment constitutes both the machine on which the program is running and other machines with which there exists a communication path. A method by which a program can be written to achieve such communication without knowledge as to what machine will be on the receiving end of the communication is provided. Knowledge as to what low-level protocol will be used to connect separate machines is not required at the time the application is written.
