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...

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, ...

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...

As multiprocessor systems become more complex their reliability will need to increase as well In this paper we propose a novel technique which is applicable to a wide variety of distributed real time systems especially those exhibiting data parallelism We assert that for high reliability a combination of system level fault tolerance and application level fault tolerance works best In many syste...

Enterprise applications can be structured as domains, where each domain contains objects that are replicated for fault tolerance, with the replication being managed by a fault tolerance infrastructure local to the domain. Gateways can allow unreplicated clients to bene t from the fault tolerance services of the replicated servers, without compromising replica consistency within the fault tolera...

Wireless sensor networks (WSNs) have wide variety of applications and provide limitless future potentials. Nodes in WSNs are prone to be failure due to energy depletion, hardware failure, communication link errors, malicious attack, and so on. Therefore, fault tolerance is one of the critical issues in WSNs. The chapter investigates current research work on fault tolerance in WSNs. We study how...

Software fault-tolerance techniques have been widely used in computing systems to achieve high level of quality. Rejuvenation, a modern software fault-tolerance technique, has attracted a large number of researchers in software engineering area. Evaluating the effectiveness and feasibility of this technique becomes extremely important in selecting, comparing and applying it in actual software s...

To achieve fully autonomous systems, fault tolerance is often employed. Fault tolerance is the ability to continue operation in the presence of faults. Fault diagnosis is an essential component of fault tolerance, especially for autonomous robotics. It is the process of determining as much information as possible about the fault, especially the origin of the fault. However, a real time fault di...
