Reflective Fault-Tolerant Systems: From Experience to Challenges
This paper presents research work performed on the development and the verification of dependable reflective systems based on MetaObject Protocols (MOPs). We describe our experience, we draw the lessons learnt from both a design and a validation viewpoint, and we discuss some possible future trends on this topic. The main originality of this work relies on the combination of both design and val...
متن کاملAdaptive Fault-Tolerant Systems and Reflective Architectures
As the environment of a fault-tolerant system increases in complexity, the system’s performance may be degraded if it has to respond to all conditions in the service range at any time. The performance may be improved if the system is able to adapt its structure to changing environmental conditions. Adaptation may be valuable not only at run time but over the entire life-cycle. At run time, adap...
متن کاملFault-tolerant disk storage and file systems using reflective memory
Most replicated storage and file systems either take a specialized hardware approach or a sofhuare-oriented approach to fault tolerance. This paper describes a fault-tolerant disk storage and file system that falls in between the hardware and software categories. The system uses Reflective Memory to interconnect an array of standard computers comprising a massively parallel system. This archite...
متن کاملAdaptive Fault Tolerant Systems: Reflective Design and Validation
Reflection has been used with some success, since quite a few years now, for dealing with separation of concerns and transparency of fault-tolerance mechanisms for the application. Nevertheless, it has also shown some concerning the control of fine-grain information such as thread control or other deep aspects of the platform. We propose here the use of a new concept, called multi-level reflect...
متن کاملImplementing a Reflective Fault-Tolerant CORBA System
The use of reflection becomes today popular for the implementation of non-functional mechanisms such as for fault-tolerance. The main benefits of reflection are separation of concerns between the application and the mechanisms and transparency from the application programmer point of view. Unfortunately, metaobject protocols available today are not satisfactory with respect to necessary feature...
