Abstract

The present invention is directed to a system for multiplexing data transmissions exchanged between a host computer system and a user workstation connected by a communications link. One or more host application programs reside upon and are executed by the host computer system while a terminal emulation program having the capability of simultaneously displaying one or more host application program screens resides upon and is executed by the user workstation. The data transmission multiplexing system comprises a session manager program residing upon and executed by the host computer system for establishing one or more program sessions with the host application programs, each of the program sessions generating its own individual datastreams, and a single program session with the terminal emulation program utilizing a single connection between the host computer system and the user workstation. The terminal emulation program simultaneously displays the host application program screen for each of the program sessions established between the session manager program and the host application programs. The multiplexing system includes a multiplexing program for performing the following functions: (1) building inner data packets from the individual datastreams generated by each program session; (2) inserting the inner data packets into one or more data transmission packets for transmission between the host computer system and the user workstation over the single logical connection; and (3) removing the inner data packets from the one or more data transmission packets for recreating the individual datastreams therefrom.
