    The application area of distributed systems determines the extent to which protocols must provide fault detection and/or fault tolerance. Highest dependability can not be obtained without the cost of a substantial overhead. In order to reduce the message number and the time consumption, protocols should be tailored best to application requirements and system properties. This paper presents a novel...

    In order to accomplish dependable onboard evolution, we develop a methodology which is called “guarded software upgrading” (GSU). The core of the methodology is a low-cost error containment and recovery protocol that escorts an upgraded software component through onboard validation, and guarded operation, safeguarding mission functions. The message-driven confidence-driven (MDCD) natur... View full abstract»

    In late 1997, IEEE standardized the physical layers and the medium access for wireless local area networks. This paper presents a performance study of the distributed coordination function, the fundamental contention based access mechanism. Most performance studies adopt unchecked simplifying assumptions or do not reveal all details of the simulation model. We develop a stochastic Petri net model,... View full abstract»

    The evolution of communication technologies results in continuously increasing capacities and higher concentration of traffic on relatively fewer network elements. In order to avoid the influence of these failures on the services provided by the network several network resilience schemes have been developed and applied in real networks. The objective of the paper is to present a reliability analys... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (180 KB)

    For the class Superposed Generalized Stochastic Petri Nets (SGSPNs) we present a new analysis algorithm which combines the ideas of transient numerical analysis via uniformization and discrete event simulation. Simulation is used to determine the firing times of synchronized transitions describing interactions between the components of a SGSPN. Numerical analysis is used to compute the distributio...

    Cooperative applications are widely used, e.g. as parallel calculations or distributed information processing systems. Whereby such applications meet the users demand and offer a performance improvement, the susceptibility to faults of any used computer node is raised. Often a single fault may cause a complete application failure. On the other hand, the redundancy in distributed systems can be uti... View full abstract»

  • NFTAPE: a framework for assessing dependability in distributed systems with lightweight fault injectors

    Many fault injection tools are available for dependability assessment. Although these tools are good at injecting a single fault model into a single system, they suffer from two main limitations for use in distributed systems: (1) no single tool is sufficient for injecting all necessary fault models; (2) it is difficult to port these tools to new systems. NFTAPE, a tool for composing automated fau... View full abstract»

    A non-intrusive, reusable framework for collecting performance statistics of CORBA-based distributed systems is proposed. The usefulness of the framework in the context of comparing performance improvement techniques is described. Also discussed is application of this framework to a large telecommunications application and experimental results on its relative overhead View full abstract»

  • On Markov reward modelling with FSPNs

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (460 KB)

    In this paper fluid stochastic Petri nets (FSPNs) will be used for modelling reward in a performability model. Two variations of a known performability model are presented in order to demonstrate the ability of FSPNs in modelling accumulated rate reward as well as accumulated impulse reward. In the first model two fluid places are used, one of which represents the profit (reward) obtained by opera... View full abstract»

    Simulation studies are used to evaluate the impact of the distributional and correlational characteristics of traffic arrival processes on the performance of network routing elements. It is shown that synthetic traffic models that capture only the distributional or the correlational characteristics of real workloads can yield substantially optimistic predictions of queue lengths and drop rate.

    The mission time analysis of large dependable systems that can be described by Markov Reward Models (MRM) with phase type distributed impulse and constant rate rewards is considered in the paper. A single Laplace transform domain description of the distribution of completion time is provided through a new analysis approach.

    We study queueing systems where customers have strict deadlines until the end of their service. An analytic method is given for the analysis of a class of such queues, namely, M(n)/M/1+G models with ordered service. These are single-server queues with state-dependent Poisson arrival process, exponential service times, FCFS service discipline, and general customer impatience. We derive a closed-for...

    Dynamic fault tree analysis, as currently supported by the Galileo software package, provides an effective means for assessing the reliability of embedded computer-based systems. Dynamic fault trees extend traditional fault trees by defining special gates to capture sequential and functional dependency characteristics. A modular approach to the solution of dynamic fault trees effectively applies B... View full abstract»
