Abstract:Due to the deregulation of the telecom network and the Internet, users will have access to an increasing number of heterogeneous communication services and will need to adapt their services or learn new services in order to interact with other users and systems. We propose a dynamic composition method that enables services to be constructed dynamically or "on-the-fly" from existing functional elements (service roles). Roles and actors that play roles are key concepts in our approach. A service role is defined as the part an object takes in a service. Service execution requires that roles are assigned to actors in a coordinated way. Our approach enables the systematic and structured specification of services, and provides mechanisms for service composition and an execution environment.

“…So far in this project, a wide range of topics have been dealt with, and many objectives been achieved. Four main architectures have been developedDthe basic architecture, mobility handling architecture, dynamic configuration architecture, and the adaptive service configuration architectureD for detailed information see [1,2,3,4,5,6] and the URL: http://www .item.ntnu.no/ -plugandplay. •rl TAPAS basic architecture, illustrated in Figure 1, is based on generic Actors (software components) in the Nodes of the network that can download Manuscripts defining Roles tobe played each represent different functionality.…”

Abstract:Mobility is regarded as the most important feature needed to achieve adaptability and flexibility in the execution of service components. As such, service systems could be able to cope with the handling of dynarnic changes in the availability of resources and position of users. On the other hand, providing user-centric and personal-content driven wide range of services, more commonly wireless ones, to end users regardless of their location and used equipment, seem to be the most important objective of such a feature. Mobility, in this context, is a feature facilitating the free and coordinated movement of, for instance, users, software components, user terminals, etc. One should always consider the vibrant configuration and settings of not only end-users applications a:nd environment, but also the network resources, components and services. The reason is due to the ever changing and increasing demands and requirements in functionality, security, reliability and QoS. Mobility support in self-managing, dynamically configurable network architecture seems to be even more challenging, however recent development and improvements in network infrastructure show a greater prospect for codeon-demand and adaptive network management. TAPAS, and its mobility handling architecture, presented in this paper, tend to give some answers and take a step towards achieving such goals.

“…Adaptable means that the service systems will adapt dynamically to changes in both time and position related to users, nodes, capabilities, status, and changed service requirements. In TAPAS, adaptability is modelled as a 3-classes property: 1) Rearrangement flexibility, 2) Failure robustness and survivability, and 3) QoS awareness and resource control [1,2,3]. One objective is to gain experiences by implementing those various features.…”

Abstract:Adaptable service systems are service systems that adapt dynamically to changes in both time and position related to users, nodes, capabilities, status, and changed service requirements. We present a formal model for the basic entity used for the implementation of the service functionality in the Telematics Architecture for Play-based Adaptable Service systems (TAPAS). This basic entity is the role-figure, which executes in the nodes of the network. The formal model is denoted as the role-figure model. It comprises behaviour specification, interfaces, capabilities, queue of messages, and executing methods for role-figures. Its semantics is based on an ODP (Open Distributed Processing) semantic model and rewriting logic, and is used to prove properties such as: plug ability, consumption ability, and play ability.
