An object-oriented middleware for our metasystem on Internet

A metasystem is composed of geographically distributed heterogeneous resources that can be reached over the network. An essential software layer, often called middleware, maps heterogeneous hosts into a single coherent virtual machine, giving the user the power of a unique computing environment. In this paper all object-oriented middleware for the metasystem based on the Internet is described in detail. It masks the hardware details, giving the user a single-image space system with transparent data transfer and uniform program interface.
