An arrangement is provided for exposing TCP/IP profiles to a client application operating in a mobile computing environment where each profile comprises a set of TCP/IP configuration parameters that are mapped to a specific network type. An application programming interface (“API”) enables the client application to propagate configuration parameters in a selected TCP/IP profile to a TCP/IP layer in a communication protocol stack that resides on a mobile device. The TCP/IP configuration parameters are applied to data communications with a remote terminal over a network that is comprised of several links and which typically includes a wireless link.
