“…Merideth et al, [21] introduced "Thema" which is Byzantine Fault-Tolerance middleware system in order to execute the Byzantine Fault-Tolerance by capturing all requests and responses. Aghaie et al, [22] have proposed client transparent fault tolerance model for web services which applies N-version and active replication techniques to identify server errors and redirect requests to reserved backup server in order to reduce the service failures. Santos at el., [23] proposed fault tolerance infrastructure by which it adds an extra layer acting as proxy between client requests and service provider's response to ensure client transparent faults tolerance.…”

This paper proposes a goal-based modeling approach to develop security requirements of Security-Critical Systems (SCSs) through explicitly factoring the faults into the requirement engineering process. Our approach establishes the Security Requirement Model (SRM) of the system based on its respective Security Fault Model (SFM).We incorporate fault tolerance into the SRM through considering the partial satisfaction of security goals. The proposed approach factors this partiality into the goals by using proper mitigation techniques during the refinement process. This approach eventually contributes to a fault tolerant model for security requirements of the target system.

“…Suitable fault assessments are paramount to assure the system's performability in terms of fault tolerance and performance. Several studies have emphasized fault-tolerant architectures, their mechanisms, and criticality in ensuring service availability and delivery in service systems (Garcia & Toledo, 2007;Laranjeiro et al, 2008;Aghaei et al, 2011;Ahmed & Wu, 2013;Vargas-Santiago et al, 2017;Li et al, 2018;Pandey et al, 2019;Dahling et al, 2021). Relatively, existing fault-tolerant architectures have been centered around redundant mechanisms in terms of replication (active and passive), diversity, and N-Version Programming Laranjeiro et al, 2008;Hosseini & Arani, 2015;Kumari & Kaur, 2018;Pandey et al, 2019;Abdi & Shahoveisi, 2022).…”

Performance is a critical attribute in evaluating the quality and dependability of service-oriented systems dependent on fault-tolerantarchitectures. Fault-tolerant architectures have been implemented with redundant techniques to ensure fault-tolerant services. However, replica-related overhead burdens fault-tolerant techniques with associated performance degradation in service delivery, and this consequentially discourages service consumers with discredits for service providers. In this paper, a fault-tolerant approach thatadopts replication and diversity was employed on agent-oriented coordination toward guaranteeing the performance of the proposedfault-tolerant architecture solution under a large-scale service request load. In addition, the resultant architecture solution was simulated with Apache JMeter for performance evaluation considering the performability in the absence and presence of a fault load. The simulation experiments and results revealed the architecture’s efficiency in fault tolerance via the timely coordination of logicaland replica-related activities by software agents. Noteworthily, the continued service availability and performance were guaranteed for the architecture solution with a significant rate of regularity in the absence and presence of a replica-related fault. Therefore, this study’s performance evaluation methods and results could serve as a veritable milestone for building fault-tolerant service systems with appreciable performability and contribute to the service-oriented fields where performance is inevitable.

Safety-critical systems are widely used in many sectors to prevent fatal accidents and prevent loss of life, damage of property, or deterioration of the environment. Implementation of software safety standards as part of the development of safety-critical software is generally considered an essential element of any safety program. Therefore, it has become more critical to produce highly reliable software to meet the safety requirements established by functional safety standards, such as IEC 61508, ISO 26262, and EN 50128. IEC 61508 supports well-known safety mechanisms such as design diversity like N-version (multi-version) programming. N-version (multi-version) programming is a method where multiple functionally equivalent programs are independently developed from the same software specifications. N-version (multi-version) programming is particularly an effective approach to increase the quality of software in a safety-critical system. In this paper, one of the well-known and widely used algorithms in the field of N-version (multi-version) programming, the majority voting algorithm, has been modified with an online stability checker where the decisions of the voter are judged against the stability of the underlying system. The plant where all the theoretical results are implemented is a tilt-rotor system with the proposed N-version (multi-version) programming–based controller. The experimental results show that the modified majority voter-based N-version (multi-version) programming controller provides more reliable control of the plant.
