Modeling User-Perceived Service Availability,ased on user behavior, and derive formulas to compute service availability starting with the user behavior model and the system model. To automatically generate high fidelity user and system models, we use Stochastic Reward Nets (SRNs) and demonstrate how to combine the user SRN model and the system

Dependable Distributed Computing Using Free Databases, help in the implementation of dependable applications. There are in particular various free databases that make it economically feasible to run a database on each computer in a system. Hence, one can partition database tables across multiple hosts to harness the processing power and disks of multip

On the Importance of Composability of Ad Hoc Mobile Middleware and Trust Management,chitectures which will support this ubiquity must meet many requirements at both runtime and over their lifecycle. Composability is one key requirement for such services. In this paper we provide refined definitions of composability as it applies to such distributed services, encompassing both hardw

Proof-Based System Engineering Using a Virtual System Model,stems. PBSE is of particular relevance for safety critical applications and other systems where dependability properties are essential. This is particularly the case for applications in the aerospace domain targeted in the EC FP6 Integrated Project ASSERT. Applying PBSE both permits to eliminate mos

Evaluation of the Impact of Congestion on Service Availability in GPRS Infrastructures,ll as affected by an outage and through a transient analysis we evaluate the effectiveness of a specific class of resource management techniques for congestion treatment in terms of service availability related indicators. The classical availability analysis is thus enhanced, by taking into account

Characterizing Session Initiation Protocol (SIP) Network Performance and Reliability,, it becomes increasingly essential to characterize both the performance and the reliability of the signaling entities utilizing the protocol. We provide an analytical look at the performance of a SIP network as well as a reliability model of SIP servers.
