Abstract

This is a method for incremental downloading of a software application with several components. First, a small stub module is downloaded. The stub module then downloads some subset of the application's components sufficient to launch the application. While the application runs, the need for additional components is detected. If the required components are unavailable locally, there are downloaded from a file server, and the locally maintained listing of available components is updated accordingly. The method described can also be used to update a software release in a similar, incremental manner.
