The loss of fairness due to parallel TCP connections and the new UDP applications imply an architectural change in Internet’s structure. Service Differentiation is a new concept that defines simple methods to improve Quality of Service. The key modules of this model are the profile verifiers located in edge routers. They are charged of creating a tag for each packet based on this verification. ...

This study examines the effect of consumers’ preand postservice encounter performance (SEP) on their satisfaction and repurchase intention in online markets. Specifically, we suggest that, in an online context, the different service performances: preand post-Service over time, affects consumer evaluation (i.e., overall satisfaction and repurchase intention) of a vendor. We introduce the experie...

In this paper, we address the problem of dynamic server selection among a set of object servers, as the ones defined by CORBA and DCOM, providing the same service type. These servers are not necessarily replicas but may have different interfaces and belong to different service providers. As a solution, we propose a novel architecture that we call LoDACE. This architecture has been designed to a...

The introduction of Internet of Services technologies is promoting manufacturing servitization of Cyber Physical Production Systems for the most important Manufacturing 4.0 capabilities, namely self-awareness, self-configuration and selfrepairing. In addition, industrial data are emerging as a new industrial asset, creating new opportunities for operations improvement, and increase industrial v...

Heterogeneous subscriber base with wide range of wireless services makes the wireless service market more challenging for a service provider (SP). This challenge is related to the revenue model of the SP, where pricing policy plays a central role. The pricing policy should be such that an SP will recover the investment while keeping the desired level of customer satisfaction. An ideal pricing p...

With an increasing number of devices that must be managed, the scalability of network and service management is a real challenge. A similar challenge seems to be solved by botnets which are the major security threats in today’s Internet where a botmaster can control several thousands of computers around the world. This is done although many hindernesses like firewalls, intrusion detection syste...

The Transport layer, designed for old networking contexts and now obsolete applications requirements, is inefficient. This paper discusses the reasons behind this inefficiency and the obstacles to the evolution of Transport protocols. The discussion is then extended to derive new requirements for the Transport layer, both functional and architectural, in order to ensure optimal performances in ...

This paper aims at exploring how ICTs can improve decision-making processes and subsequently service performances in public sector services. The authors focus on a specific class of Information Systems: Decision Support Systems (DSS) and Business Intelligence (BI). The research presented will lay the ground for investigating how the impact of these technologies on public services can be evaluat...

In this paper the authors present a procedure for estimating the impact of design choices, dealing with subsystems architecture, basic components reliability performances or maintenance policies, on the service quality provided by a railway or metro system. The procedure is based on the use of an innovative modular simulator, developed by the authors. Through a Monte Carlo approach and a suitab...

Car registration and inspection simulation experiment to analyze business functions of the traffic department in Al-Ain city in United Arab Emirates (UAE) is reported. The car registration is managed by a government organization in association with a private network service company that looks after the inspection service. A visual AweSim car registration simulation model is developed from workf...
