Abstract

Abstract This invention teaches a method and system for a computer program to accomplish communication in a computer environment which is independent of the system upon which the program is executing. This computer environment constitutes both the machine on which the program is running and other machines with which there exists a communication path. A method by which a program can be written to achieve such communication without knowledge as to what machine will be on the receiving end of the communication is provided. Knowledge as to what low-level protocol will be used to connect separate machines is not required at the time the application is written.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 202 words
In a method of accomplishing data communications in a system which is portable to a plurality of computer operating environments, said system including a manager for controlling the passage of a datacomm message within said system and a plurality of communication paths, a method of dynamically configuring a communication path by a user, said method comprising the steps of: a) requesting said manager to configure said communication path by a user; b) said manager acquiring a list of protocol modifier programs and protocol interface programs that comprise said communication path; c) said manager storing said list of protocol modifier programs and protocol interface programs as part of the path configuration; d) said manager calling a next program configured in said list of protocol modifier programs and protocol interface programs with a configuration request; e) said next program executing a sequence of configuration steps; f) said next program notifying said manager when said configuration steps are complete; g) repeating said steps c, d, and e until all programs configured in said communication path have been called whereby a configured communication path is provided for inter-process communication between a plurality of application programs; and h) generating a key to identify said configured communication path.
Claim 2
Dependent Claim 202 words
In a method of accomplishing data communications in a system which is portable to a plurality of computer operating environments, said system including a manager for controlling the passage of a datacomm message within said system and a plurality of communication paths, a method of dynamically configuring a communication path by a user, said method comprising the steps of: a) requesting said manager to configure said communication path by a user; b) said manager acquiring a list of protocol modifier programs and protocol interface programs that comprise said communication path; c) said manager storing said list of protocol modifier programs and protocol interface programs as part of the path configuration; d) said manager calling a next program configured in said list of protocol modifier programs and protocol interface programs with a configuration request; e) said next program executing a sequence of configuration steps; f) said next program notifying said manager when said configuration steps are complete; g) repeating said steps c, d, and e until all programs configured in said communication path have been called whereby a configured communication path is provided for inter-process communication between a plurality of application programs; and h) generating a key to identify said configured communication path.
Claim 3
Dependent Claim 24 words
The method in step e in claim 1 wherein said configuration steps comprise: said manager acquiring additional communication path information from said user interactively.
