Research ArticleOpen accessEvery word in the titleComparison Study of Transmission Control Protocol and User Datagram Protocol Behavior over Multi-Protocol Label Switching Networks in Case of FailuresTaha Ahmed Al-Radaei, Zuriati Ahmad ZukarnainProblem statement: In only a few years, Multi-Protocol Label Switching (MPLS) has evolved from an exotic technology to a mainstream tool used by service providers to create revenue-generating services. MPLS provides a high reliable Label Switched Path (LSP). MPLS failures may degrade the reliability of the MPLS networks. Approach: For that reason, many studies have been conducted to keep the … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,949 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUnderstanding Information System Failures from the Complexity PerspectiveIndranil MukherjeeProblem Statement: Failure of computer based information systems had been a source of major concern in the modern technological era. Information System (IS) researchers have spent a significant amount of their time and effort in understanding the recurring failure of Information Systems. Studies in this regard have ranged from being primarily technical in their approach to those having a much … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 10,621 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Conflict-Free Routing Tables Update Method for Persistent Multilink and Node Failures in SDN ArchitecturesYannick Florian Yankam, Jean Frédéric Myoupo, Vianney Kengne TchendjiThe large-scale network management abilities of centralized architectures, such as Software-Defined Networking (SDN), are attracting increasing interest from major computer networking companies. In this architecture type, the nodes follow the rerouting rules predefined by the control plane in the controller. However, when a link or node failure becomes persistent over the time, the controller must recompute the routing and rerouting … …Journal of Computer Science, Vol. 15, Issue 3 · 11 Mar 2019 · 7,469 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSERVER FAILURES ENABLED JAVASPACES SERVICEMutasem K. Alsmadi, Usama A. Badawi, Hatem M. MoharramJavaSpaces service is a Distributed Shared Memory (DSM) implementation. It has been introduced by Sun Microsystems as a service of the Jini system. Currently, JavaSpaces support client side fault tolerance. It enables both transaction and mobile coordination mechanisms for such purpose. The application failures could be detected and recovered. However, server side failures may occur during the application runtime. Therefore, … …Journal of Computer Science, Vol. 10, Issue 4 · 21 Dec 2013 · 6,643 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCost Analysis of a System Involving Common-Cause Failures and Preventive MaintenanceM.Y. HaggagProblem statement: Many authors have studied the cost analysis of a two-unit cold standby redundant system with two types of unit failure, but no attention was paid to the reliability of a system involving common-cause failures and preventive maintenance. Question was raised whether the preventive maintenance would be effective on the reliability and performance of the system. Determine the efficacy … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,606 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReliability Evaluation of Distributed Computer Systems Subject to Imperfect Coverage and Dependent Common-Cause FailuresLiudong Xing, Akhilesh ShresthaImperfect coverage (IPC) occurs when a malicious component failure causes extensive damage due to inadequate fault detection, fault location or fault recovery. Common-cause failures (CCF) are multiple dependent component failures within a system due to a shared root cause. Both imperfect coverage and common-cause failures can exist in distributed computer systems and can contribute significantly to the overall system unreliability. … …Journal of Computer Science, Vol. 2, Issue 6 · 28 Sep 2006 · 6,838 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExploration of the Nexus between Corruption and Implementation Failures in Anti-Trafficking Policies and Laws in South AfricaMorero MotsekiWe step into a workplace, having a lot of expectations to work cordially and reverently with each other. But sometimes in life, we come across different personalities who would impact negatively. The negativity can be understood based on frustration and stress because that will be passed out. But if it is periodical, rudeness, and bossiness towards the employees, this results … …Journal of Social Sciences, Vol. 18, Issue 1 · 23 Jun 2022 · 5,769 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleECONOMIC AND PERFORMANCE EVALUATION OF STOCHASTIC MODEL ON A BASE TRANSCEIVER SYSTEM CONSIDERING VARIOUS OPERATIONAL MODES AND CATASTROPHIC FAILURESRajeev Kumar, Sunny KapoorIn this study a stochastic model for a Base Transceiver System (BTS) is proposed that consists of various hardware and software components. A Base Transceiver System (BTS) may undergoes four modes during its operation viz normal, congestion, down and failure mode. The hardware and software components may have various types of major and minor faults. The occurrence of a minor … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 22 Jul 2013 · 7,075 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeo-Seismic Environmental Aspects Affecting Tailings Dams FailuresJuan M. Mayoral, Miguel P. RomoSeismic performance evaluations of tailings dams are essential for characterizing the geo-environmental risks posed by these earthen structures, which should include the geotechnical hazards implied by slope instability failure, free board loss and the potential release of contaminants. The observed damage is more important when liquefaction occurs on the dam body and foundation, which often leads to cracking, settlements, tilting … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,086 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAsymptotic Confidence Limits for a Repairable System with Standbys Subject to Switching FailuresJau-Chuan Ke, Ssu-Lang LeeThis paper studies system performance measures and asymptotic confidence limits for the mean time to failure, steady-state availability, steady-state failure frequency of a repairable system which two primary units, two standby units, and one repair facility when switching to standbys may fail. …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 6,922 accessesView PDFCite
