Abstract

A system and method is described for expediting the transfer of data in a network system wherein a user is coupled by a slow-speed data transfer facility to a first user environment which is the primary interface system for the user. The user begins the process by requesting the download of a data packet. The user interface sends a request for source information to the first user environment along its slow-speed data transfer facility. The response to the request consists of the source information of the data packet. The source information is received by the user interface, and is then sent to the second user environment having a fast-speed data transfer facility. The second user environment locates the data packet using the source information, and downloads the data packet to the user interface through the fast-speed data transfer facility. In a further aspect of the invention, the first user environment operates in accordance with CICS protocols, and uses a HLLAPI interface in conjunction with a user interface, and the second user environment is a MVS platform, coupled to the user interface with a TCP/IP connection. The user requests the download of a data packet a block of source code, and the CICS region returns the program name, the date and time it was compiled, and the MVS dataset name containing the source program information. Since CICS runs on a layer on top of MVS, this MVS dataset is available to both operating systems. The source information is then sent to the workstation, restructured and then sent by the workstation through a TCP/IP connection to MVS. MVS receives the source information, locates the dataset, and begins to download the source code.
