the present invention relates to improvements for managing remote function calls and other mechanisms for managing the remote invocation and control of programs . a separation of the request - driven communication work from one broad unstructured bulk of work into at least two separate portions of management is proposed : a dispatching portion and one or more connection portions . connections are not closed but are reused whenever advantageous , which yields better performance . a standardized interface is set up which is able to be used by a plurality of different requester applications . thus , a way is found to pass a rfc connection from one application to another , and the same rfc connection can be used by totally independent applications .
