Artificial evolution can integrate fault tolerance considerations into the automatic design process, producing inherently fault-tolerant designs without explicit redundant parts. Population dynamics can give rise to some level of fault tolerance ‘for free.’ Requirements for fault tolerance can also be incorporated into the fitness function. The practicalities of these methods are investigated, ...

Traditionally, fault tolerance has been considered a pivotal component of system design. However, as modern commodity hardware becomes increasingly reliable, building dedicated fault tolerance systems becomes unnecessary. Therefore, while in this paper we propose nothing novel and make no technical contributions, we nevertheless identify a unique approach to fault tolerance, which we dub optimi...

Fault-tolerance is the survival attribute of the real-time software system. The software should provide correct results in the face of various failures. A major technological concern for the coming years is the ever widening gap between the demand for high quality, robust software and its supply. Software fault tolerance is basically the design faults in the computer system. Its function is to ...

The main purpose of this paper was to find a simple solution for load balancing and fault tolerance in OSGi. The challenge was to implement a highly available web application such as a shopping cart system with load balancing and fault tolerance, without having to change the core of OSGi. Keywords—Fault tolerance, load balancing, OSGi, shopping cart system.

Fault-tolerance analysis reveals possible system behavior under the influence of faults. Such analysis is essential for satellites where faults might be caused by space radiation and autonomous recovery is needed. In this paper we present a statistical simulation approach for fault-tolerance analysis of satellite On-Board Computers (OBCs) that are based on Commercial Off-The-Shelf (COTS) compon...

The routing algorithms for parallel computers, on-chip networks, multi-core processors, and multiprocessors system-on-chip (MP-SoCs) exhibit router failures must be able to handle interconnect router failures that render a symmetrical mesh non-symmetrically. When developing a routing methodology, the time complexity of calculation should be minimal, and thus complicated routing strategies to in...

Abstract: The security aspects and fault tolerance of the computational network provides have a crucial impact on the designing and use of networks. It provides the framework for securing the networks with the unwanted faults and to increases the reliability of the fault tolerance network. The conceptual view for provide secure the networks and diagnose the faults. In this paper we have carried...

We present a new software architecture in which all concepts necessary to achieve fault tolerance can be added to an application automatically without any source code changes. As a case study, we consider the problem of providing a reliable service despite node failures by executing a group of replicat-ed servers. Replica creation and management as well as failure detection and recovery are per...
