Availability-Based Software Performability Model with User-Perceived Performance Degradation
This paper discusses software performability evaluation considering the real-time property. We assume that the software system has two operational states from the viewpoint of the end users: one is operating with the desirable performance level according to specification and the other is with degraded performance level. The time-dependent behavior of the system is described by the Markovian sof...
متن کاملService availability and discovery responsiveness : a user-perceived view on service dependability
Services play an increasingly important role in modern networks, ranging from web service provision of global businesses to the Internet of Things. Dependability of service provision is thus one of the primary goals. For successful provision, a service first needs to be discovered and connected to by a client. Then, during actual service usage, it needs to perform according to the requirements ...
متن کاملModeling of user perceived webserver availability
We propose to use Markov regenerative process (MRGP) models to study the availability of Internet-based services perceived by a Web user, which capture the interactions between the service facility and the user. The necessity of the sophisticated MRGP modeling is evidenced by the comparisons with the corresponding continuous time Markov chain (CTMC) models, which show that the popular convenien...
متن کاملSmart City Reference Model: Interconnectivity for On-Demand User to Service Authentication
The Internet of Things and Services (IoTS) has encouraged the development of service provisioning systems in respect to Smart City topics. Most of them are operated as heterogeneous systems which limits end customers’ access and contradicts with IoTS principles. In this paper, we discuss and develop a reference model of an interconnected service marketplace ecosystem. The prototypical implement...
متن کاملA Conceptual Model for Service Availability
Traditionally, availability has been seen as an atomic property asserting the average time a system is “up” or “down”. In order to model and analyse the availability of computerised systems in a world where the dependency on and complexity of such systems are increasing, this notion of availability is no longer sufficient. This report presents a conceptual model for service availability designe...
