Method and apparatus for preloading data in a distributed data processing system
First Claim
1. A method for reducing network traffic in a distributed data processing system, the method comprising:
- pre-loading a plurality of pages associated with an application onto a client data processing system from a server data processing system;
hibernating the client data processing system after the plurality of pages has been pre-loaded onto the client data processing system to form an image containing the plurality of pages; and
executing the application using plurality of pages on the client data processing system, wherein the client data processing system is unhibernated, the application is executed using the image without accessing the server data processing system.

Abstract
A method and apparatus for reducing time needed to initialize a data processing system and to execute applications on the data processing system. In accordance with a preferred embodiment of the present invention, pages for an application are pre-loaded onto a client from a server. The pre-loading of the application includes loading pages that will be required for execution of the application in preparation for hibernation. These pages may include other pages for executable code or data that will be used during execution of the application. Subsequently, the application is executed using the locally stored pages without having to retrieve pages from the server. In addition, an application is provided with an opportunity to prepare itself for hibernation via hibernation notification. For example, the application may read and process files from the server. This processing is done once prior to hibernation and is not required for later executions of the application.
