Abstract
Abstract The system and method of this invention automatically routes a connection between data processing systems in different network domains. As an example, an application running on a data processing system utilizing a network domain such as TCP (Transmission Control Protocol), can automatically make a connection to another data processing system utilizing a different network domain such as SNA (Systems Network Architecture). The connection is automatically performed in the layer containing the communication end point objects. In a preferred embodiment, the connection is automatically performed in the socket layer of the AIX operating system, or in the socket layer of other operating systems based upon the Berkeley version of the UNIX operating system.
