The Network Hardware is the Operating System

To build a distributed operating system the mi-crokernel approach is the most popular. To build an adaptable operating system a minimal microker-nel is preferred. But for an adaptable and exible distributed operating system the previous approaches are not enough because they create an artiicial barrier to OS distribution and harm system transparency and adaptability. This paper express how adaptable distributed systems could be built and describes an example implementation named OO where the microkernel itself and its abstractions are both distributed and adaptable. It is shown why the system interface should be close to the hardware but not restricted to a local node. The whole network is considered to be the exported and multi-plexed hardware in contrast to what is done by today microkernel in \distributed" OSes eliminating the arti-cial view of nodes as isolated entities.
