This paper presents the realisation, using a Service Oriented Architecture, of an approach for dynamic flexibility and evolution in workflows through the support of flexible work practices, based not on proprietary frameworks, but on accepted ideas of how people actually work. A set of principles have been derived from a sound theoretical base and applied to the development of worklets, an exte...

A voice over IP quality monitoring architecture based on the development of the VQuality library is described. VQuality implements the E-model and its extensions for objective voice quality measurement. The library also supports generation of a customized voice quality CDR with extensions that permit transfer of call quality parameters measured over different instants of time, besides interacti...

Service granularity generally refers to the size of a service. The fact that services should be large-sized or coarse-grained is often postulated as a fundamental design principle of service oriented architecture (SOA). However, multiple meanings are put on the term granularity and the impact of granularity on architectural qualities is not always clear. In order to structure the discussion, we...

AMnet provides a framework for flexible and rapid service creation. Its primary goal is to provide customized multicast services on demand, thus providing a framework for a flexible open communication platform. AMnet is based on active and programmable networking technologies and uses active nodes (AMnodes) within the network. These AMnodes are executing on-demand loadable service modules to en...

Financial applications in the field of risk/return management demand for powerful and at the same time flexible information technology resources. These requirements seem to be highly suitable for service-oriented computing concepts. In this paper we identify promising risk/return management services and analyze the specific value proposition of service-oriented computing in this context. Taking...

As the share of services in economies grow globally, the efficiency of service production becomes crucial. Despite the many studies on service efficiency, it has proven difficult to find the right measures. The main reason is wide range of services from simple to complex, and from mass to professional services. Consequently, there are no commonly accepted measurement frameworks for comparing th...
