The Inherently Distributed Adaptable Oo Kernel

To build a distributed operating system the microkernel approach is the most popular. To build an adaptable operating system a minimal microkernel 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 describes the implementation of the OO system, where the microkernel itself and its abstractions are both distributed and adaptable. We show how the system interface is close to the hardware but not restricted to a local node. The whole network is exported and multiplexed hardware in contrast to what is done by today microkernel in \distributed" OSes. In this way the artiicial view of nodes as isolated entities can be eliminated and the system can maintain both adaptability and other good properties for system distribution as inherent features.
