Pre-emptive download of software in data processing network

摘要

Software modules (e.g. dynamically loadable code such as java applets) are pre-emptively transferred in a data processing network from a host data processing system for execution on a client data processing system. The software modules are of a number of different types, each type providing a different service at the client system (e.g. e-mail, text editor etc). The host system determines the type of a first software module transferred to a client and makes a prediction, based on this determination, as to the type of software module that may next be required at the client. The predicted software module is then transferred to the client system in advance of any request for same from the client.
