Runtime reconfiguration considered as “applying required changes to a running system” plays an important role for providing high availability not only of safetyand mission-critical systems, but also for commercial web-applications offering professional services. Hereby, the main concerns are maintaining the consistency of the running system during reconfiguration and minimizing its down-time ca...

Aspect-oriented (AO) middleware is a promising technology for the realisation of dynamic reconfiguration in distributed systems. Similar to other dynamic reconfiguration approaches, AO-middleware based reconfiguration requires that the consistency of the system is maintained across reconfigurations. AO middleware based reconfiguration is an ongoing research topic and several consistency approac...

The support of reconfiguration requires the existence of negotiation procedures and trading rules connecting the device reconfiguration manager with the corresponding network proxies that will operate between the network proxies and the managed equipment, and will enable the exchange of information (e.g. mode availability, access network capabilities) or the ordering of certain procedures to ta...

Digital computers embedded in critical applications such as flight controls should be equipped with appropriate fault-tolerance schemes to ensure their reliable and safe operation in the presence of component failures. System reconfiguration, which enhances reliability by dynamically using spatial redundancy, is generally the most time-consuming faul t/errorhandling stage. The reconfigurutzon l...

In case of redundant systems some kind of faults could be tolerated simply by changing the rulebase of the control system by a system (strategy) reconfiguration. One solution for this kind of system reconfiguration could be the combination of the fuzzy clustering based symptom evaluation and the hierarchical interpolate fuzzy reasoning the similarity based system reconfiguration. Its main idea ...

Here we introduce one simulated and two physical three-dimensional stochastic modular robot systems, all capable of self-assembly and self-reconfiguration. We assume that individual units can only draw power when attached to the growing structure, and have no means of actuation. Instead they are subject to random motion induced by the surrounding medium when unattached. We present a simulation ...

Self-reconfiguration is a technique using which configured logic can quickly modify itself at runtime to suit application requirements. Although performance improvements using self-reconfiguration have been demonstrated, the technique itself has been only informally described. Based on an abstract reconfigurable device model, a precise definition of self-reconfiguration is presented in this pap...

High-speed reconfigurable processors incorporating a reconfigurable memory and microprocessor array into a chip have been developed [1]. Such devices use a context-switching method. Their internal reconfigurable memory includes reconfiguration contexts of 16 banks. One bank includes a reconfiguration context used for ALUs that can be changed to others on a clock in nanoseconds. These devices ha...

The growing popularity of wired and wireless Internet requires distributed systems to be more flexible, adaptive and easily extendable. Dynamic reconfiguration of distributed component-based systems is one possible solution to meet these demands. However, current component frameworks that support dynamic reconfiguration either place the burden of preparing a component for reconfiguration comple...

Run-time reconfiguration of FPGAs has been around in academia for more than two decades but it is still applied very seldom in industrial applications. This has two main reasons: a lack of killer applications that substantially benefit from run-time reconfiguration and design tools that permit to quickly implement corresponding reconfigurable systems. This tutorial gives a survey on state-of-th...
