Abstract

Exemplary methods and apparatus for improving speed, scalability, robustness, and dynamism of software installation package data transfers and software installation modules on processing devices are provided. Software installation modules utilize a priori or on-demand transfer of sets of files or other data to remote processing devices for software installation to take place. The fully distributed data transfer and data replication protocol of the present invention permits transfers that minimize processing requirements on master transfer nodes by spreading work across the network and automatically synchronizing with software installation modules to perform software installation or update resulting in higher scalability, more dynamism, and allowing fault-tolerance by distribution of functionality as opposed to current methodologies. Data transfers occur persistently such that new nodes being added, or alternatively nodes recovering from a crash that occurred before or during the data transfer phase, will automatically and asynchronously proceed to complete the missed data transfer phase and perform the software installation or update as required.
