Paramecium: an extensible object-based kernel
@article{Doorn1995ParameciumAE, title={Paramecium: an extensible object-based kernel}, author={Leendert van Doorn and Philip Homburg and Andrew S. Tanenbaum}, journal={Proceedings 5th Workshop on Hot Topics in Operating Systems (HotOS-V)}, year={1995}, pages={86-89} }
We describe the design of an extensible kernel, called Paramecium. This kernel uses an object-based software architecture which together with instance naming, late binding and explicit overrides enables easy reconfiguration. Determining which components reside in the kernel protection domain is up to the user. A certification authority or one of its delegates certifies which components are trustworthy and therefore permitted to run in the kernel protection domain. These delegates may include…

This paper describes the design and implementation of a system that provides operating system style protection for Java code, which uses hardware protection domains to separate Java classes, provide access control on cross domain method invocations, efficient data sharing between protection domains, and memory and CPU resource control.
Isolation, resource management and sharing in the kaffeos java runtime system
- Computer Science

It is demonstrated that in the presence of malicious or buggy code that engages in a denial-of-service attack directed against resources, KaffeOS-based systems can contain the attack, remove resources from the attacked applications, and continue to provide robust service to other clients.
The Inherently Distributed AdaptableO
- Computer Science
- 1997
This paper describes the implementation of the OO system, where the microkernel itself and its abstractions are both distributed and adaptable and the system can maintain both adaptability and other good properties for system distribution as inherent features.
Towards object-based wide area distributed systems
- Computer ScienceProceedings of International Workshop on Object Orientation in Operating Systems
- 1995
This work advocates an object-based approach to distribution, which allows for flexibility because many of the technical detail of distribution, such as communication protocols, consistency rules, etc. can be hidden behind the objects' interfaces.
Dynamic Memory Model Reconfiguration in DEIMOS
