Abstract

A method, system, and apparatus for distributing and using portions of a computer-based application over a network, such as the internet. The present embodiment executes streamed chunks of code associated with an application on demand by binary emulation. Therefore the present invention enables execution of applications on network-based computer systems thereby enabling flexible distribution and use of executable code over a network. By streaming the transmission of non-sequentially ordered code chunks the present embodiment enables overlapping of streaming and execution of code chunks and reduces network latency effects of the past. The present embodiment may also speculatively stream the code chunks associated with the application to further reduce network latency effects associated with transmission of the code chunks.
